The avowed aim of all modern classification in biological science is to gronp together those forms of life which have a close genetic ivlationship, and to show how they are related.

Mr. Darwin-'^ has called attention to the fact that, however unconsciously on the part of the systeniatist, descent has really entered into the classification in that no matter to what degree the two sexes may differ in the most important charac- ters, they are placed together in the same most limited division, the species. The ideal natural system would consist of a complete gene- alogical table of all forms, exhibiting the phylogenies of groups and their subdivisions. There could be only one such perfect system, but it would admit of various expression. However far we are from its attainment, we may well be glad that a start has been made in the right direction. The attention of students is now being directed from the analytic to the synthetic aspect of the subject. From a dry, wearying process of sorting and pigeon-holing different forms for convenience in management, we have advanced to a study of theii" development and of the varying lines of descent through which they have attained their present condition — a study of great philosophic importance and of absorbing interest to the student. In his " Evolution and Taxonomy,"t Professor Comstock suggests that " the logical way to go to work to determine the affinities of a group of organisms is first to endeavor to ascertain the structure of the primitive members of this group, and then endeavor to learn in what v/ays these primitive forms have been modified by natural selection, keeping in mind that in each generation those forms have survived whose parts were best fitted to perform their functions." He lilso suggests that the study be prosecuted by applying the method to a single organ ; then to another, and so on till a consistent history is obtained. The essay gives his study of the evolution of the wings of insects, especially of the Lepidoptera, and presents a provisional system of classification based upon the results of that study. At the suggestion of Professor Comstock, and under his dii'ection and encouragement, the present study of the antennie has been undertaken. The material for the work has been obtained largely from my own collecting in the vicinity of Ithaca, N. Y., and I have been allowed to avail myself freely of specimens from the extensive collection of the University. The slides of mounted antennae of all specimens used in the mori)hological study are deposited in the University collection. ••• The Origin of Species.

ANTENNiE OF LEPIDOPTERA. 6 I wish to ticknowlcd^t' my i:rcat indebtedness to Professor Com- stock for his coustiint readiness with suugestioii and advice and for the invahiable assistance lie iias given nie throngh his jjapers and by personal conversations. I am also nnder obligations to Mr. Alex. D. ]\IaeGillivray for tlic invariable kindness with wliicli he has aided me in the work. For morphological study the antennae were removed from the head, and, after dehydration in 95 per cent, alcohol and subsequent im- mersion in clearer, mounted in Canada balsam. Each slide was labeled with the name of the species, sex, and the side from which the antenna w'as removed. The last item is of great importance, as it enables the observer to determine the relative aspects in the subse- quent study. For histological study the antenuai were removed with great cai'e not to tear away the soft parts at the base. Some were fixed and hardened with parts of the head still attached. The chitin f(n-ms A dense covering over the softer parts, and it was possible to obtain better results in the fixing and hardening, and especially in the in- filtration with collodion, if the antenna was first cut into moderate lengths so as to allow the fluids to work in from the ends. The tissues were fixed in various fluids. The Pici-o-aceto-sublimate, de- vised by Dr. P. A. Fish, gave the best results. It is composed of fifty per cent, alcohol, lOOOcc. ; glacial acetic acid, 5cc. ; corrosive sublimate, 5 grams ; picric acid, 1 gram. After immersion in this fixer for twenty-four hours, the tissues were passed through '}0, 67, 82 and 95 per cent, alcohols and imbediled in collodion. The wlu)le was cleared in the castor-thyme oil mixture* — red oil of thyme, three parts ; castor oil, one part. Where exti-a thin sections were desirable, the cut surface was painted with one per cent, collodion before each section was made. This aided very materially in pre- venting the tearing away of the softer parts from the tough chitin. For staining, both Delafield's hematoxylin and the simple hema- toxylin with a counter-stain of eosin produced excellent results. After considerable study of the natural attitude of the antennae in live specimens, both in flight and at i-est, and also of the position taken when the insect is killed and .-spread, the conclusion has been reached that the normal position is assumed when the antenn;e are extended directly laterad, with the most specialized surfaces ventrad, * A New Clearer for Col lud ionized Ohjei'ts, I\ A.

Some exceptions to the last clause will be noted later. This description of the normal position and Fig. 26, representing the de- nuded head and its appendages of Sphiiu- cher.'^is, will make clear the application of the terms of position and direction employed in the following pages. The natural position varies greatly in different species. In some the antennae are directed nearly cei)halad ; in others, almost as nearly caudad ; and all the possible positions be- tween these extremes may be assumed. As the antenna^ are true appendages, however, the general rule for the normal })osition of appendages should obtain in all cases. MORPHOLOGY. The antenme belong to the pre-oral somite, and are usually the most conspicuous pair of appendages of the head. They are slender, segmented organs, and are inserted symmetrically, one on each side of the meson, on the dorso-cephalic surface between or cephalad of the compound eyes. In the Papilionina and Hesperiina, according to Mr. Scudder,* and so far as I have observed, in the other Lepi- doptera, the antenniie are inserted at the ends of the suture between the epicranium and the clypeus, see Fig. 26. Kolbef says that, " In the Diptera, Lepidoptera and Trichoptera, whose mouth-parts are stunted, absent, or transformed into sucking organs, the antennae are l)rought very near each other, while in the biting insects they usually are sej)arated from each other." Mlcropteryx, one of the Jugatse, which has retained its mouth-})arts slightly modified, has its an- tennae inserted (|iiite far cephalad and relatively far apart; thus it offers a peculiar confirmation of the generalization of Kolbe. It would seem that, since the change in function of the mouth-parts has not yet become complete, as indicated by the presence of those organs in a condition less modified than in the other Lepidoptera, the migration of the bases of the antennae has not progressed so far as elsewhere in the order. The insertions here are at the ends of the clypeal suture, but the sutui'e itself is strongly curved with the ends bent cephalad. The proximal segment of the antenna is the largest and is termed * The Butterflies of the Eastern United States and Canada, in three Vols., by S. H.

Next it is the pedicel, which is smaller than the scape, but larger than the segments immediately distad of it, except among some of the Hesperiina and Papilionina. The scape and pedicel together are often called the base, while all the remaining segments make up the clavola. Among the moths the latter is often pectinate, or feather-like, Fig. 8. There is much confusion in the nomenclature of this form, ])ut in the following pages the general form will be tei'med pectinate ; the })art made up of the bodies of the segments, the shaft; and the projections, pectinations; Fig. 8, sh. and pe. Among the skij)[)ers and l)utterflies the clavola is divided into a proxinud, thread-like portion, the funicle, or stalk ; and a distal, fusiform, or clavate part, the club. Figs. 4 and 5. The scape is inserted into a little cup-like depression of the head, and is itself more or less rounded in at the i)roximal end. Very often a constriction causes this end to take the shape of a spherical knob, which, with the corresponding cavity in which it fits, makes a very serviceable ball and socket joint. This permits great freedom of motion in many planes, and to a considerable extent provides for a rotary motion. The scape and pedicel also are joined in such a manner as to allow considerable movement. The other joints, how- ever, are comparatively stiff and afford little or no motion. HISTOLOGY. The scape is abundantly sup])lied with strong, striated muscles, while in the other segments of all forms I have examined in sections, I have been unable to demonstrate the presence of muscular tissue. Fig. 20 represents a longisection of a segment with the two joints at the ends and shows the shape of the contiguous parts. The chitinous parts are held together by a tough, compact membrane, and it is due to the elasticity of the latter that, when the clavola is flexed by ex- ternal force, it is able of itself to resume its natural shape. A .sec- tion of this membrane is well shown in fig. 18, me. Figs. 20 and 22 will make clear the internal anatomy of the clavola. Just entad of the chitinous coat is a layer of varying thickness composed of dermal and nerve-cells with numerous interlacing nerve-fibres. Along the ventral part of the shaft runs ji large tracheal trunk supplying the branches to the segments. Just dorsad of this trachea lie a pair of large nerves wbieh come from the frontal ganglion and send out branclies to the various organs of sen.se locateil in the antenna. The TKANS. AM. ENT. SOC.

The chitinous covering of the antennae is of the same general character as that of the body, but it is neither so thick nor so com- pact in structure. It lies just ectad of the layer of dermal cells making up the limiting stratum of the vital tissues of the insect and is doubtless formed by the secretion from those cells. Its surface is fre(|uently marked off into more or less nearly hexagonal areas. Fig. 34, which, in some cases, are said by various authorities to corre- spond to the underlying layers of cells. They are limited by very thin, continuous ridges of chitin sometimes, e. g. in Notolophus lea- costigma, Fig. 30, raised as high as 3 m. from the surface. In other cases there is an external layer of overlapping j^lates which may or may not mark the outlines of the dermal cells. Figs. 38 and 39. The surface of the plates is often broken up into fine points and ridges which frequently obscure the outlines of the plates themselves. In still other forms there is a covering of fine hairs which are really simple projections of the chitin itself and quite different from the true hairs described below. Fig. 40. The many structures found on the antenme of the Le})idoptera which have originated from the interior may all be regarded as modifications of a simple hair. Each has its origin in a hypodermal cell, and therefore is connected with the interior through a pore- canal. The simplest form is that of a simple, protective hair, situ- ated at the ectal end of a pore-canal. In the structure of the chi- tinized parts it differs slightly, if at all, from the sense-hair described later, but it lacks any connection with the vital tissues. Whether it is an imperfect form of sense-hair, or whether it is in the condition best adapted to the function it has to perform, is a question Ave are unable to answer. A simple ffattening out of a hair, followed by some corresponding changes in the secondary details of structure, would give the type of a scale. These also arise from a hypodermal cell, though in the imago the connection is lost. Fig. l(j shows the position and manner of insertion of the scales. The pedicel, or stalk, is set in a goblet shaped cell lying in the chitin with its long axis nearly perj)endicular to the surface, but pointing slightly distad. The bottom of the cup is at the end of a pore-canal, but there is no evident vital connection with the interior. When the scale is extracted, or has fallen out, the insertion-cups have the appearance of two externally tangent, or antexx.t: of lepidoptera. t slightly overlapping circle, the distal one a little the larger. This manner of insertion differs considerably from that found in tiie wing- membrane and described by Professor Kellogg.* There the cups have their long axes nearly parallel with the surface, and they seem rather to be built up upon the membrane than to be hollowed out of it. Scales vary greatly in form in different j)artsof the sanie antenna. The scape bears a patch of extremely long, little specialized scales spread over the dorsal surface towards the distal end and forming one or two very pronounced, often strongly colored tufts. Single scales of this kind attain great length, while their thickness remains small. One from the scape of a male Hemileuca maia measured 1888 X 5.2 vi. Mr. Scudder saysf that in the butterflies (by which term he includes the Hesperiina and Papilionina) the basal pai't of the base (i e., the scape) is always naked. In many cases, however, these tufts cover at least the distal half of the scape ; in some all the surface except that Avhich forms a part of the joint. This tuft- ing is carried to an extreme, or rather it is reinforced in a peculiar manner among the Epipaschiin?e. Here the length of the scales is supplemented by an extension of the dorsal surface of the scape into a long process, which in some sjiecies reaches nearly to the abdomen. Fig. 28. This is thickly clothed with long, spatulate scales, the whole forming a very prominent feature in the appearance of the insect. It is regarded l>y ^Ir. Hulst^; as a secondary sexual development. On the clavola the scales are more specialized, and have the same form as those on the wing of the same insect. Among the moths, for the most part, they are arranged on the dorsal surface in two transverse bands, the scales themselves lying with their long axes parallel with the axis of the clavola, and the free ends pointed distad, Fig. 49. Thus the scales of the distal band cover the joint between the segment on which they are born and the one succeeding. In many pectinate forms the pectinations also bear scales. Even in those antennse which are scaled apparently over their whole surface, there is a comparatively free space on the ventral and more highly specialized face. * The Taxonomic Value of the Seniles of the Lepidoptera, V.

JANTARV, 1896. 8 • DONALDSON BODINE. Of the various antennal organs which have a communication with nerves, and are therefore presumably organs of special sense, I shall describe six kinds : 1. Short, slender, pointed sense-hairs which are hollow, but closed at the free ends ; Fig. 23, 1 , shows these in their relation to the rest of the antenna; Fig. 13 represents a section magnified about 500 diameters. The hair is attached to the chitinous ring at the end of a pore-canal. It has been described as movably articulated, but there is no muscular tissue connected with it as with the hair of ^[ammuls. The elasticity of the connecting zone of chitin may allow a certain amount of flexion and of subsequent extension, but it can scarcely be said to be movable in the active sense. In the specimens I have examined the external part of the hair does not exceed 45 m. in length, and it is usually more or less flexible. From the interior a fibre from a branch of the antennal nerve passes out into the cavity of the hair. Ruland* says the question whether the nerve, ascending through the pore-canal to a ganglioual swelling, ends in the base ; or whether it sends up a modified continuation into the interior, is not yet settled. He is unable to decide to his satisfaction. Some of my preparations seem to me to show clearly that the nerve itself extends some distance into the hair. Just entad of the hair Hes a large nerve-cell. It is more or less ovate in form, with the smaller end produced into the pore-canal. It contains from three to six nuclei, which are coarsely granular in apjiearance. Au " axis-cylinder" is clearly visible in the apical part of the cell, but it fades from sight toward the middle. This ty})e of sense-hair has a wide distribution. It occurs very generally in both the Jugatic and the Frenatie. Mr. Scudderf says that in no instance has he observed the antennae of the butterflies clothed with hairs. He doubtless refers, however, to hairs of a dif- ferent type described below. Those of the fir.st kind are more or less abundant in many forms. 2.

Tliey are usually shorter than the third type of sense-hair, but in some cases they are longer. In Xotolojjhiis leucodujma, Fig. :-50, they measure 350 m. It is extremely difficult to obtain good sections of the soft parts of these sense-organs, because of the toughness of the chitinous parts, and the ease with which the cellular elements tear away from them in the cutting. As shown in Fig. 14, we have here more than one cell in connection with the sense-hair. I liave been unable to determine whether all three are nerve-cells and receive branches from the nerve-trunk. That at least one is supplied with a nerve is cer- tain. At a later date, with fresh material, I hope to devote further study to the histology of this form. Whether in all these cases the cell is really a nerve-cell and has true nerve processes, is a matter of uljt. AVhether the nerve is really a part of the cell, or sin)ply intimately connected with it by the apposition of a brush end has not been determined, and could j)erhaps be oatisfactorily demonstrated only by the application of the ( Jolgi method. AVhichever condition may be the true one, however, it is doubtless constant in all forms, and so cannot affect the problem under consideration in this paper. The distribution of the sense-hair of the second ty})e is as wide as that of the first type, but the number is limited to a very few on a single segment. 8. Long, rather stout and stiff hairs which, like those first de- scribed, are hollow and closed at the free ends ; Fig. 23, 3, shows these in relation to the rest of the antenna, and Fig. 12 represents a section of one from a male Callosamia promethea, magnified about 500 diameters. It will be seen from the figure that the structure differs but little from the first type. The nerve-cell, however, is relatively smaller, and the hair is more firmly attached. The ex- ternal portion of the hair usually measures from 80 to 100 )n. I have found none less than 75 m., while some attain a length of 350 m. In distribution they are more limited than the other types. They do not occur in the Jugatse, nor in the Hesperiina and Papili- onina. 4. Pits, or depressions, guarded at the opening l)y stiff i)rojections of chitin, ami containing single rods or cones, which are connected with nerves from the interior; Fig. 15 represents a section of one from a male Callommi a promethea. In this species the pit is a de- pression in the chitin from 8 to 10 m. deep, and of almut the same TEANS. AM. ENT. SOC. XX III. (2) JANUAKY, 1896. 10 DONALDSON BODINE. diameter. Rising from the floor is a chitinous cone about 3 vi. in diameter at the base and 6 m. high. The apex is somewhat atten- uate and is open. The nerv^ous apparatus is much like that in the first type of sense-hair. It is broader at the apical part and passes directly into the cone, filling the broad base. Sometimes two, or even three of these pits are grown together. In such cases there is a reduplication of all parts. Among the butterflies they are much deeper, and are supplied with stiff* guarding projections from the walls, Fig. 17. The cone, also, is smaller in diameter at the base, and is almost or quite rod-like in form. In at least some cases, e. g. Pijramels eardni, there is a circle of stiff* points around the base of the cone. Hauser* describes such a bristle circle in Vanessa io. Kraepelin and Raland,t however, from the study of diff*erent species, dispute the existence of such a structure. Pits have a wide distri- bution throughout the whole order. They are found for the most part on the ventral surfaces both of the shaft and of the pectina- tions. In the butterflies they are most numerous on the club. Hauser says they are not limited to the two terminal segments alone, as Lespes has declared, but are spread over the whole club. In Van- essa atalanta I have found them in all but the three proximal seg- ments of the clavola. 5. Short projections which have become so thick as to lose their character of hairs, and which in many cases have a covering con- tinuous with the general integument of the segments ; Fig. 20, 5, represents the form of these cones and shows their relation to the segment. Fig. 18 represents a section of one from a male (h/lo- samia promethea. The nerve apparatus resembles that of the rods in the pits described under 4. In fact the whole api)aratus seems like an everted pit. The termination of the cone varies in different species. In some the end is blunt and even hollowed out; in others there is a fine point at the a})ex ; in still others there are several points. Figs. 41-45. The distribution of the cones is wide. They occur in all the families of the Frenatje, excepting the Hesperiina and Papilionina, and possibly the Fyromor[)hid:c. They are not fi)und in the Jugataj. Notwithstanding their broad distribution, there is usually only a single one on a segment, and in many cases only on the segments of the distal portion of the clavola. * Physiologische uiid histologische Uiitersuchtunjieii iibcr dus Geruchsorfjander Insekten, Gustav Hauser, Eiiangen.

There is another set of nervous appuratus whicli, though it cannot aftbrd any taxononiic characters, at least not without invol- ving the careful preparation of difficult sections, may throw some light on the question of function. It is always situated in the pedi- cel. Fig. 19 represents a section through the apparatus in the an- tenna of a male Callosamia 2}roviethea. It is a sagittal section of the ventral half of the pedicel, with parts of the adjacent segments ; but the apparatus extends around the whole segment, so that a lon- gisection in any plane would present essentially the same appear- ance. As the antennal nerve-trunk enters the pedicel, it gives off on all sides nuiiierous branches, which extend peripherad. When it approaches the outer wall each nerve bends distad and joins a nerve-cell with a distinct nucleus. Extending distad from the cell is a long, slender rod with one or more nucleal bodies. These rods are gathered into small conical bundles and terminate within pores situated in the mend)ranous ring which connects the chitinized walls of the pedicel and the proximal joint of the clavola. It will be remembered that the base is the movable part of the antenna ; while the clavola, except in case of the application of external force, is as one piece. It at once becomes evident that any movement of the clavola upon the base, whether due to its contact with some object or to a vibration caused by a vibration in the air, would be at once felt in the membrane in which these rods lie. As there are rods in every part of this membrane a definite impression of the movement would be produced in the sense-rods. FUNCTION. That the antenna) function as organs of s])ecial sense there can be no question. Just what the sense, or senses, may be, we cannot tell, but we may ai)proxiinate the true character. When we consider how little we know of the essential operations which accompany our own perceptions, we nnist realize the difficulty of the i)roblem. We can form definite ideas of what sensations are possible to insects mainly by interpretations of physiological action and of histological structure, as conqoared with similar actions and structures in our- selves and in the higher animals. Doubtless the range of perception in insects is widely different from our own ; yet, that there must be considerable similarity in the organs, fidlows from the fact that the external substances or forces nmst work through the same media in both cases. TRANS. AM. ENT. SOC. XXIII. JANUARY, 1896. 12 DONALDSON BODINE. The senses which might be supposed to have their peripheral or- gans in the antennse are touch, taste, smell, and hearing. The evi- dences of their existence we may class under two heads : histological and physiological, normal, and artificial or experimental. Touch. — A very little observation will convince one that the an- tennse arc peculiarly sensitive to . impressions of touch, and it seems very probable that the several types of sense-hairs already described are especially adapted to the receptio'is of such impressions. Blix* holds that in man all hairs are organs of touch, though at the same time they serve for protection. The sensation of pressure at least is closely associated with the hairs. In insects where the body is cov- ered with a hard sliell of chitin, we may fairly assume that the hairs are even more effective as intermediate organs between the external influence and the nerve termination. It is not at all improbable that the diflerent types of hairs are receptive of diflferent sorts of sensa- tions, as of touch, j^ressure, weight, etc. The greater abundance of hairs in the nocturnal nioths and their sparser distribution among the diurnal forms would seem to be correlated with their use as touch organs. One who has watched Ctenucha virginica, or some form of night-flying moth, will have little doubt that the antennse serve as "feelers." It may not be impossible or even improbable that the sense of touch in these organs is not limited to conditions of actual contact with the objects perceived. Many phenomena connected with the actions of moths possessing these organs very highly developed point to the conclusion that there must be a sort of feeling at a distance sucii as we know of among some higher forms which are sightless. Taste. — Histologically, we might suppose it possible that the pits and rods or the cones might function as organs of taste. Some authors hold that during life the pits may be filled with a mucous secretion. I do not think so, but if there were a fluid in them the api)aratus would closely a[)i)ro\'imate the condition found to prevail in the taste organs of the higher animals. Experiments, however, have shown pretty conclusively that taste does not reside in the antennre. It has been found that by the use of the antennae waspsf could not distinguish powdered sugar from alum or dolomite, and only recog- nized the difference when some of the substance reached the mouth. * Exper.

OF LEPIDOPTKRA. 13 Smell. — There can l)e little doubt that the .sense of smell is very acute in the Lepidoptera. Hundreds of species of both moths and butterflies are known to possess special organs for the emission of odors. Di-. Fritz Muller* says that the males of DuJonl'^ bihli^, one of the Nymphalidie, is able to emit as many as three distinct odors, each kind being produced by a separate apparatus. The possession of contrivances for the emission of such odors would in itself argue the existence of organs for their detection. The wonderful celerity with which the Noctuidse and Arctiida? can iind "sugar" at trees or in open places lends additional weight to the belief that thei*e must be well-developed organs of smell. The only tenable theory to ac- count for the well-known habit of " assembling" among Le})idoptera is based upon their [)ossession of an extremely acute sense of smell or something very akin to it. This habit is not confined to any one grouj), though it is most fre(piently observed among the Saturniina. It has been notedf in many widely separated families, e. g., Hei)iali(he, Tortricina, Geometrina, Noctuina, Lymantriidje, Lithosiidse, Zy- gsenidpe, etc. The most remarkable exam})le that has come under my notice is recoi'ded in "The Entomologist" of December, 1S4, 121, 163, 218; vol. xxvi, j). 21 ; vol. xxvii, p.

The Avhole ap- proach was made in a more or less indefinite manner, as if they were guided by the varying strength of the scent, and, even v/hen the fe- males were close to them and in ])lain sight, the males would still fly blindly about striking the sides of the building, and at last reaching the cage only after many wide detours. Dr. Westcott describes, in the " Entomological News" for JNIay, 1895, his experience with Ce- cropias. In four days he took 342 males who came to a cage where females were confined. At one time he counted 218 about the cage at the same time, when it contained only four females. Males of Samia ceeropia have been known to anticipate the emer- gence of the female from the cocoon. In many forms where the female has lost her wings, or possesses them in a very rudimentary condition, she does not fly at all, or does so only to seek a place for depositing her eggs. As many as 183 species have been enumer- ated where the wings of the females are either greatly reduced or entirely absent. In these cases the males must seek the females, and observations show that they succeed in doing so in a wonderfully short space of time. These are certainly i*emarkable manifestations of some sense of pei'ception, which, in many respects, must resemble our sense of smell. That the sense here concerned is not in any direct way connected with that of touch or with the sympathetic vibration of sense-hairs or organs, is proved by the example quoted above where the males were attracted to a bag from which the fe- males had been removed for some time. The fact that " assembling" takes place among moths which have filiform antennre also argues against the view that the pectinate forms by the vibration of their abundant hairs communicate at a distance. There are many reasons why the pits and rods of the antennse should be regarded as the peripheral organs of this sense. Histo- logically, there is much evidence in favor of the view. There is a supporting tissue with a perforated end, which would allow free communication between the air and the nerve or a thin protecting membrane, through which the perception may take place. The origin of the anteniial nerve also presents some evidence that the sense of smell resides in the antennse. Viallanes* says the antennal * Etudes histologique et orgauologiqiic sur les centres nei'veux et les Orjianes des Sens des Aniniaux articules. Ann. de Sci. Nat. Zoologie, Huitieme Serie, T. 14.

His chief argument for this theory is that the antennal cases of the pupae are practically alike in both sexes and are larger and more complex than the adult antennte of the female would warrant, though at the same time less developed than the adult male antennae. A different ex- planation, however, may be offered. In these families ovij)osition takes place very soon after the emergence of the female from the cocoon and neither the male nor female adults seek footl to j)rolong their existence. Their m()uth-[)arts have been lost or have ceased to he functional. If this habit of early oviposition was acquired before the antennae had time to develop very far, it is plain that there would lie little tendency in either male or female to attain better antennae for aitl in the search for food. At the same time the struggle of the males to find the females quickly would cause a sudden and extreme specialization of their antennae, without a corresponding influence upon the female. Darwin has pointed out that " peculiarities ap- pearing in the males of our domestic breeds are often transmitted either exclusively, or in a much greater degree in the males alone." This would seem the more natural explanation of the condition we find among the Lepidoptera. It is so common to find the female with antennie much less developed, that it is difficult to believe that they all have degenerated from a form intermediate between the l)resent male and female antennae. It is a much simpler and reason- able explanation and one which is as fully in accord with the facts to believe that in the large majority of cases the females have simply not kej)t })ace with the males in the specialization of their autennie. Whichever may be the true explanation, the comparative study of the series is equally instructive. Degeneration is apt to retrace the steps by which the form Avas specialized, and so affords nearly as good illustrations of intermediate stages as would the real progressive series. Another suggestive serie-s is afforded by the gradation of the pec- tinations on the different portions of the same antenna. The medial and proximal parts show the more advanced stages, while the distal retains the earlier and simpler ones; see the gradation in Fcltia subgothica, Figs, 9, 11, 10. This, however, is not true in the case of those organs which find their most favorable situation at the distal end. TRANS. AM. ENT. SOC. XXIII. JANUARY, 1896. 22 DONALDSON BODINE. From a comparative study of these corresponding forms in the two sexes and of a large series of male antennae, I conclude that the evolution of the pectinations was essentially as follows: A single pair of pectinations originated on the ventro-distal edge of the seg- ment. As development went on there was a steady selection of those, forms in which the pectinations had their origin less toward the ex- treme distal end. The result was that the bases of the pectinations graduallv migrated proximad. In addition to this movement there was also a tendency towards a migration dorsad. This last was a slower and a later method of specialization, but one which more directly resulted in an increase of the sensitive ventral surface. Among the Saturniina we find a further development. Here, with the exception of the Bombycidse proper, we find the pectinations are dorsal, and where they have largely developed and have migrated to the extreme proximal ends of the segments, a second pair have originated as outgrowths from the distal edge of one segment towards the overshadowing pectinations of the proximal edge of the adjacent segment. The earlier form of this is seen in Automerb to, Fig. 8, w^here the distal pair of one segment is so closely apposed to the larger proximal pair of the next, that it is difficult to see the line of junction except with a considerable magnification. In Tropcea luna the distal pair have begun to migrate proximad and have be- come independent of the older and more firmly established ones. In Saniia ceeropia the two })airs of each segment are more nearly equal throughout the clavola, while in Philoifamia cynthia, Fig. 3, the distal pair have migrated so far proximad as to occupy almost the middle of the segment. We have seen how natural selection has caused an increase in the area and spread of the sensitive surface. Along with this process there was a diflPerentiation of the hair structures themselves, and doubtless a corres])onding increase in their efiiciency. It is probable that in the primitive form of antenna a diflferentiation had already taken place between hairs for protection and for sense-perception. The simplest form of the latter sort has already been described as a hair of the first type. A comparative study of types two and three will show that, while they are quite distinct from the first and from each other, no great change would be necessary to transform the first into either the second or third. Intermediate forms do not exist in the same antenna, but difierent species show difierent degrees of variation from the first type. ANTENNiE OF LEPIDOPTERA. 23 The long, stout, rigid hair of the second type arose very early, before the separation of the Jugatre from the Frenatie, and long before the third type originated. The latter type was developed subsequent to another division which took place after the separation of the Jugatue from the Frenatai, and also after the Hesperiina and Papilionina had branched off from the Frenate stem. It departs less widely from the first type, and it is evidently specialized as a touch organ. It reaches its highest development among the Noc- tui(l:e, Lymantriidie and Arctiidic. At first siglit the pits are very different from the simple sense-hair. Nevertheless, I believe that in essential characters they differ from them much less than do the hairs of the second type. The antenuie of a female Eparyyrem titijru.i will show that iu many of the pits hairs very like those of the first type occupy the place of the short rods found in the more highly developed pits, and different specimens will present various stages of transition from the hair in a compara- tively slight pit to a short rod in a deeper one. This shoAVs that the structure is not yet definitely fixed in character, and that it may vary greatly in a short time. The cones are a distinct development, however, and in all prob- ability originated but once. This must have been after the separa- tion of the Jugatse and the Frenati3e, and also after the Hesperiina and Papilionina had l)ranclied off from the latter. All the Frenatie, except these two superfamilies and possibly the Pyromorphidio, pos- sess these organs. They are quite constant in location. In all of the ]Microfrenatpe, and in most of the Macrofrenatre, they are dis- tributed one to a segment as shown in Figs. 46 -50, and they form a very conspicuous feature of the antenna. In some of the Macrofre- natie, however, they number more than one to a segment, and in pectinate antennte they have often migrated from the shaft to a posi- tion ui)on tlie i)ectinations. Fig. 25 represents a portion of the ven- tral aspect of the antenna of Phryga)udea calif ornica where the cones still occcupy a position on tlie shaft. Fig. 27, representing a portion of the right antenna of a male Zeuzera pyriui, shows this migration with the cones situated part way toward the distal ends of the pectinations. Fig. 30 shows a portion of a pectination of the antenna of a male Xotolophus lencodujma with the cone at the ex- treme distal end. Among the Saturnidic, the number of cones to a segment is greatly increased. Fig. 7 represents a distal portion of the antenna of a female Trojxva /una with clusters of cones in the TKANS. AM. KNT. SOC. XXIII. JANUARY. 1896 24 DONALDSON BODINE. same position usually occupied by the single one. It is perhaps worth noting here that, while the females are usually behind the males in the development of pectinations, they are not at all deficient in the number or the perfection of the cones. There is yet another feature which is of importance in determining the relationship of an antenna. This is the character of the surface of the chitinous exoskeleton of the clavola. In the Jugatps the sur- face as a whole is even, but has numerous slender prolongations which have received the name of fixed hairs, Figs. 51 and 53. These are not articulated with the chitin as are the true hairs. They are simply points which are continuous with and parts of the general surface and do not originate at the ends of pore canals. In the Fi'enatj« these are not found, but the surface of the whole clavola is divided up into more or less hexagonal areas bounded by thin con- tinuous plates set normal to the surface, or into a series of more or less imbricated plates with various surfaces and outlines. These two distinct kinds of surface covering are of great importance, as they represent specializations differing in kind, and therefore indicate a dichotomous division in the line of descent. There are other char- acters which would indicate the same thing, but no other autennal character shows that the Hesperiina and Papilionina branched off* from the other Frenatae after their separation from the Jugataj. The degrees of specialization attained in this character of surface are also worthy of attention as they sometimes afford clues to the real posi- tions of families. The surface marking of the chitin of the clavola in the Frenatse presents a great variety of forms, but with the possible exception of a few apparently aberrant cases it is possible to trace a pretty definite line of development })assing through them all. This is important, because it means that the system originated but once. The sim})lest and i)rol)ably the most primitive condition exists in the anteinia; of the Pyralidina. Here we find the general surface smooth, but di- vided up into more or less hexagonal ai'eas, fenced off' as it were by continuous plates of chitin standing nornuxl to the surface. The areas thus demarcated are said by some authorities to correspond with the outlines of the underlying dermal cells, and it may be that the plates represent the edges of separate areas of chitin developed from the cells as centres. In the adult condition of most forms, however, I do not believe that the arrangement has any relation to the underlying structures. Fig. 34 represents a portion of the an- ANTENNvE OF LEPIDOPTERA. 25 tennal surface of a male Pyramta oxydalis, and shows the great regularity of the areas so characteristic of this group of moths. Among the TortricicUe we find that in most cases the areas become elongated. Fig. 35, a portion of the antcMina of a male Dlcliella sulfureana, shows this condition. This elongation of the areas is carried much farther among the Tineids. Tinea dorsutrigella, Y'xg. 36, shows this extreme lengthening of cells and straightening out of the cross-lines ; yet here we still find the plates continuous. The function of these plates is doubtless to strengthen the thin layer of chitin and give it greater rigidity. In those forms which have long slender pectinations we find the longitudinal plates nnich thicker and heavier, while the transverse ones are less developed and have a tendency to straighten out or to disa})])ear. This is evidently better adapted than the hexagonal arrangement to stiffen these slender forms. Fig. 30 represents the dorsal aspect of a pectination of a male Notolophus leueosfigma, and shows at the sides some of the plates in j)rofile, while the accentuation of the longitudinal plates is clearly seen in the middle of the figure. Note also that the longi- tudinal plates extend slightly beyond the end of the pectination. One cannot help being struck with the resemblance between the striae or ribs of the scales and these thicker ridges on the chitin surface. On the ventral aspect of the same pectination we find a modification somewhat different, but yet along the same line. The abundance of the sense-hairs and the other organs makes a lighter and more deli- cate surface desirable, and here the transverse plates are either want- ing entirely or transformed into longitudinal ones. In fact, we may state it as a general rule that the development of chitin on the ven- tral and sensitive surface is not carried so far as elsewhere. Fig. 31 represents this condition. In all these forms the general surface is approximately level and the plates represent the only elevations from the surface. Now we come to another development. F'ig. 32 re[)- resents a portion of the dorsal surface of the antenna of a nuile Automerls to; ab is the niesal line of the shaft, and the part to the left is the extension of the surface upon the pectination. It will be seen that the portion near the meson resembles the condition found in Notolophm lencodlgma, with this difference however : in AutonierU io the general surface, instead of being level, rises on one side of each plate so as to make each area constitute a single slope with its crest at the plate on the distal edge. The surface of the sloping area is divided up into ridges with what was originally a transverse plate TRANS. AM. KNT. SOC. XXIII. (4) FEBRUARY, 1896. 26 DONALDSON BODINE. at the crest of each ridge. These ridges Avhen greatly developed extend beyond the apex of the slope and give the whole an appear- ance of being covered with fine points. This modification may be carried to an extreme. Cerura cinerea, represented in Fig. 37, will show an unusual degree of development in this direction. As a rule, however, the plates are smaller and more uniform, and form a regular imbricated surface, such as is found in Hemileuca maia or Papi/io po/i/.reiies, Figs. 38 and 39. In a smaller number of cases the surface rises to the plates on each side, making a double slope, with the plate at the crest. This may be illustrated in the antenna of Daremvia lOidv/om, Fig. 33. As might be expected, the extent to which these surface modifica- tions of tlie structure of the chitin is carried depends largely upon the development of scales. Where the antenna is heavily clothed, we find usually less departure from the primitive form of surface, especially if the scales are closely and compactly arranged. In most cases the surface of the scape and pedicel is practically smooth. This is doubtless in consequence of the covering of thick tufts of long slender scales, and also because the abundant scales of the vertex of the head aff'ord it sufficient protection. DISCUSSION OF FAMILIES. This chapter will contain a discussion of the antennae of Lepi- pidoptera by families, or groups of families, as the case may be, and will give my interpretations of the evidences they pi-esent, which may be of taxonomic value. In this discussion the provisional clas- sification of Pi'ofessor Comstock will be followed, because it is the one with which I am most familiar and because I believe it repre- sents the true relationships better than any other.* The character- izations of gr()U{)s (]Uoted in the following })ages are taken from the " ^Manual." It would be presumptuous for me to proi)ose any changes in the classification, but where the evidence of the antennal struc- tures is contrary to that of the wings, note will be made of such con- tradictions as indicating the need of further study of the group. To be complete, a classification must take into account all the structures found in the body, and it was for the pur})ose of adding the evidence of one more organ that the present work was undertaken. In most of those species where the antennae of the males and females differ * Mamial for tlie Study of Insects. John Henry Comstock and Anna Botsford Comstock, Comstock Tub. Co., Itliaca, N.

JUGAT^E. The suborder Jugataj was established by Professor Comstock, and was based principally upon important characters in some of the wing structures which represent specializations differing in kind from those of analogous structures in insects of the other suborder.* This division of the order into the Jugatse and Frenatre represents the earliest dichotomous division of the stem form of the Lepidoptera, The antennal character which distinguishes between the two lines of descent is the presence in the first of fixed-hairs upon the surface of the clavola ; and in the second, of plates or their modifications. Professor Kellogg has already pointed out that the Jugatie possess fixed hairs upon the wing-membranes ; and he regards them as an example of a " persistence of a primitive wing-covering, probably represented in the wing-covering of the living Trichoptera." It may be added that he believes their absence among the Frenatie is due to a disai)pearance. I believe that the system of fixed hairs is a distinct kind of specialization, closely resembling that found in the Trichoptera and also in the Diptcra and Hymenoptera ; while the system of plates with its later developments is just as distinct and differs from the first. If this is so, it indicates that the Jugatse are more closely related to the Trichoptera than to the Frenatse ; that the stem form passed down in two lines of descent, and that the Frenataj represent one, while the Jugatse and the Trichoptera rep- resent subsequent divisions of the other. This conclusion would really mean that the Jugatte are Trichoptera rather than Lepidop- tera. It may at first sight seem that the character of the surface coverhig is a trivial one and not worthy of so much attention. Dar- win, however, laid it down as a geneaal rule that " the le»s any part of an organization is concerned with special hal)its, the more impor- tant it becomes for classification." We may recall in this connec- tion that certain features apparently of little physiological import- ance often afford the most reliable characters. This is especially true of surface covering, e. g. hair of Mammals, feathers of Birds, scales of Reptiles, etc. * The Descent of the Lepidopteiii. J. H. Comstock, Proc. Am. Ass. Adv. So. vol. xli, 1892, pp. 199-200. TRANS. AM. KNT. SOC. XXIII. FKBRUARY, 1896. 28 DONALDSON BODINE. There are other reasons for considering the Jugatfe closely allied to the Trichoptera. The possession of a jugum, the branched con- dition of radius of the hind wings, and some other characters of the venation, the condition of the mouth-parts in Micropteryx, all point to the same conclusion. In view of all these indications, it may at least be regarded as an open question whether the Jugatse are true Lepidoptera. Another antennal character for the suborders is the absence of cones in the Jugatae and their presence in the Frenatte. The cones form a conspicuous featui'e of the antennae of nearly all Frenatae. The only exceptions known to me are the family Pyromorphidie and the superfamilies Hesperiina and Papilionina. The antennae of the Pyromorphidie, however, are all pectinate, and those of the Hespe- riina and Papilionina are so peculiarly specialized as to be easily recognizable. The presence or absence of cones, therefore, is a prac- tical recognition character. The suborder Jugatse includes two families, the Hepialidae and the Micropterygidae, and each is represented in North America by a single genus. The Hepialid/E. — The members of this family have very gener- alized antennae. Their size as compared with that of the body of the insect is extremely small. At the same time they })resent some evidences that a degeneration has lately taken place, or is even now in progress. Fig. 2 represents the antenna of a female Hep la I as argentata. The lack of regularity in the segments of the clavola and the incompleteness of the joints would seem to indicate that the character of the segmentation has not yet had time to become fixed, or that it is now in the process of evolution. The fixed hairs are very numerous, and are somewhat stouter relatively than those in Micropteryx. Correlated with this abundance of hairs there are few scales. These are inserted along the dorsal aspect of the proximal part of the clavola. The scape and pedicel are large, and are )iretty thickly clothed with long scales over nearly their whole surface. The clavolas vary considerably in the number of segments. Thirty- one is the largest number in any of the si)ecimens in the University collection. The ventral expansion of the shaft is inappreciable, and there are no pectinations in any of the forms I have seen. Sense- hairs of the first type are numerous, and there are several of the second type to a segment. Pits are })resent, but vary greatly in their (listril)ution. H. ((n/eiitdtd has few ; II. incylashani has many, thougli they ai'e not very higldy organized. ANTENNA OF LEPIDOPTERA. 29 The MrCROPTERYGiD.T5. — The members of this family have the most generalized antenuaj of any of the living Lepidoptera. As has been already noted, I find two types of antenna in the same genus. Micropteryx semipurpurella has already been described somewhat at length in the chapter on the evolution of the antennae, and may stand as a representative of the simpler type. It is so generalized in structure that I can find in it no character which would distinguish it from some of the Trichoptex'a. Compare it with Mystacides nigra, and the striking re?*emblance in structural cliarac- ters will be evident. Nor is the resemblance superficial only. The clothing of scales is practically alike in form and arrangement, the same organs exist in both. The only appreciable difference is in the number and relative length of the segments, neither of which char- acters can be regarded as of any great taxonojuic value among the Lepidoptera. The second type exhibits a remarkable peculiarity in the arrangement of the scales. ]Most of them are gathered into two radiating tufts and have their origin in two circular or oval depres- sions, one on each side of the distal half of the segment. This is a unique specialization, and I have no idea of its purpose. Fig. 51 represents a segment of the antenna of a male Micropteryx seppela (?) and shows this arrangement of scales. M. purpurella has the same arrangement on a much smaller scale, and other species vary between these extremes. Another indication of the higher specialization of this type is the presence of very broad, short scales on the scape and pedicel in addition to the ordinary covering of long narrow ones. There are also numerous long curved sense-hairs of the second type which form a sort of pointed sheath around the segment and give it the appearance of that of Anabolia bimaculata, one of the Tri- choptera. A comparison of the antenna^ of the He})iali(Ue and Micropter- ygidae will show that those of the former family are more highly specialized. Aside from tlie specialization in the scales just noted, the antennte of the Micropterygidte are very primitive. Pits and rods do occur, but in no case have I been able to find more than a single one to a segment, while in the Hepialidoe there are often many. The nearly naked surface of the clavola in Hepialm must also be regarded as an indication of a higher type. FRENATiE. The suborder Frenatte is divided by Professor Comstock into two principal sections: the Generalized Frenatie, including those fami- TRANS. AM. ENT. SOC. XXIII. I'EBRUAEY, 1896. 30 DONALDSON BODINE. lies which " are supposed to retain more nearly than any other Frenatae the form of the primitive Frenatse, those that were the first to appear on earth," and the Specialized Frenatse, including those " that depart more widely from the primitive type of Lei)idoptera, being more highly modified for special conditions of existence." The first group is a small one and comprises only five families, none of which are large. The Generalized Frenat^. I believe the evidences of the antennae of this group agree with those of the wings as given by Professor Comstock. The five fami- lies represent lower branches from the primitive stem, and so have a bond of connection in that none of them have departed very widely from the primitive type. While the evidence is not conclusive enough to show that any two of the families are genetically related, except through the common stem, there are some indications in the structure of the antennae that the Megalopygidse and Eucleidse are more closely connected than any other two families ; while the Py- romorphidie seem to represent a perfectly distinct line of descent. It is evident that if each of these families represents a distinct line of development, the grou]) as a whole will be a homogeneous one only in the sense of containing those forms which are very gener- alized, and that is the character of the group as given by Px'ofessor Comstock. That there is a wide difierence between the degree of specialization attained by the members of these families and those of any others is quite certain. I do not think any one familiar with various forms of antennae would fail to pick out those belonging to this group. The extent to which the scape and pedicel are clothed with scales ; the method of insertion of the scales more or less ob- liquely to the surface, and the irregularity in their arrangement; the scarcity of pits in most forms and the simplicity of their struc- ture ; the very slight extent of the ventral expansion of the seg- ments ; all are characters which, though perhaps not so constant in all cases as to permit of exact definition of hmits, will yet enable one to distinguish these families without much difficulty. The Megalopygid.e. — The members of this family have very generalized antennae. The segments are short and numerous. Me- ex. F. Cones very short ZYGiENlD^. FF. Cones large LYM ANTRIID^. The extent of my study and the limits of this thesis will not per- mit me to discuss each family of the Frenulum-conservers, but cer- tain features are especially worthy of note. The evidences presented by antennal structures which might point to some relationships dif- ferent from those shown in the classification of Professor Comstock are as follows : The antennte of the Cymatophoridje and the Thy- rididie seem to be closely related, and neither of them are widely separated from the higher forms of the Pyralidina. The antennae, therefore, would seem to indicate a lower position for these families than that now assigned them. The antennie of the Dioptidte are very close to those of the Notodontidie. The pectinations are more higlily developed in the former, but the cones have not even begun to migrate along the pectinations. Instead of that, they are situated upoTi slight ventral elevations of the segnients between and a little cephalad of the bases of the pectinations. In the Notodontidse, the TRANS. AM. ENT. SOC. XXIII. FEBKUAEV, 189ti. 40 DONALDSON BODINE. cones have begun to migrate as in Nerice bidentata, where they have only reached a point near the bases of the pectinations, or they have ah'eady reached the apex as in Cerurci cinerea, or Icthyura inclusa. The antennae of the Noctuidse, Lymantriidse, Agaristidse and Peri- copidse, are very similar in structure. There is a closer relation be- tween the Noctuidte and the Againstidse and between the Lyman- triidse and the Pericopidae than exists in any other arrangement of the families. The Pericopid?e also present many points of resem- blance to the Zygaenidse, especially to the more generalized forms. The Zygienidte, however, seem to be most closely related to the Py- romorphidse among the Generalized Freuat?e. Without any doubt, they belong where they are placed, high up among the Frenulum- conservers ; therefore, I believe they are the ends of the branch, which, at an earlier time, gave rise to the Pyromorphid?e. Certain of the Deltoid Noctuids exhibit a strong resemblance to the Pyralids. They are of a higher type of structure however. One group, in- cluding Herminia, Pityolita, Zauclognatha, Renla, etc., have a pecu- liar modification near the middle of the clavola, which at once sug- gests the condition of things in Desmia funeralis. In Herminia morhidalis there are simply a couple of spurs on the ventral part of a segment. The greatest development is reached in Renia re- strictalis. Fig. 28 represents this highly specialized organ in this species. The antennje of the Sphingidie resemble, in some features, those of the Notodontidre and the Noctuidse, but they are prob- ably most closely related genetically to the Sesiidse, and are repre- sentatives of a later development from the same branch. The Sphinx antenna shows as high a degree of specialization in certain directions as any of the moths. The Saturniina have more com- plicated pectinations, but that kind of a development is particu- larly adapted to their conditions of life. Among the swiftly flying Sphinxes such antennte would be unwieldy and very liable to injury. Here we find a specialization imich better fitted for habits of swift flight. Instead of long and numerous pectinations, we find greatly developed ventral expansions. The antenna of Daremma undulosa is a good example of the type ; Fig. 46 repre- sents one of the segments of the clavola. The scape is short and very stout ; the pedicel also is short and stout, and is especially well supplied with the peculiar sense apparatus common to all forms ; the clavola is large, and its shaft is heavier than in any other Lep- idoptera ; it is well protected by an abundance of scales on the AXTENX.T?

These have hairs of the third type ar- ranged on their sides in a semicircle with its opening directed ven- trad. Within the semicircle is an abundance of pits and rods. The ventral expansions are as long as the segments which bear them, and n(>ar the apex of the clavola, where the shaft is smaller in (U.ini- eter, they cause it to be more or less recnirved, as we find it among the Hosperiina. In some of the pectinate forms, e. g., Snieruithus (jeiiiiiKititx, the ventral expansions are well developed and extend far ventrad of the bases of the {)eetinations. Such forms are found among those members of the groiq) which are not so swift in flight as the other Sphingidje. The evidence of the antennte in all these cases just noted is neither clear enough nor strong enough in itself to warrant any change in the classification, but it may suggest the direction of work on other organs. For the relationships of the larger groups, I do not believe the antenuje furnish as good guides as do other organs. For, while they are subject to great variation by reason of the pe- culiar habits and environment of the particular genus or species, the}' do not afford a sufficiently large basis for variation to leave a stable and constant ground-work for the tracing out of the paths by which the specializations are brought about. In smaller groups they are of great value. The best example of this is perhaps to be seen among the Saturniina in the Fi-enulum-losers. They are often of value also when other organs seem to be constant in a number of forms, e. r/., in the Xoctuidae, Agaristidre, Pericopidae and Lyman- triidie, the wing structures are pretty constant, but the antennal structures show considerable variation and afford characters to dis- tinguish the groups. The FRENULtrM-LOSERS. The FiTiiulum-losers include the Saturniina, Lacosoniid;e, Lasio- campidse anumg the moths, and the superfamilies Hesperiina and Papilionina comprising the skijjpers and butterflies. The following table will serve to separate the anteniue of the males of this group. THE FRENULUM-LOSERS. A. Antenna pectinate. B. Pectinations ventral. C.

B. Clavola usually prolonged beyond the club, segments with some ventral expansion, often causing a recurving of the clavola beyond the club HESPERIINA. BB. Clavola not prolonged beyond the club, segments without appreciable ventral exjjansion PAPILIONINA. The most generalized antenna of this group belongs to the family Lacosomidaa. It bears a close resemblance to the antenna of the Bombycidse and the Lasiocampidae. In all three families the pecti- nations are long and slender, and arise from the ventral a,spect of the segments. They are abundantly supj)lied with hairs of the third type and have pits along the dorsal aspect, especially near the apex of the pectinations. In the Lacosomidse the pectinations are scaled, and there are fewer pits along the dorsal aspect. A study of the antennae alone would lead to the belief that the Bom- bycidse were more closely related to the Lacosomida; than to the other Saturniina. In fact, there is such a wide difference between the antennse of the first and those of the last two families of the Saturniina, that the first family would not be placed in the same superfamily were the classification based on those organs. The superfiiniily as now constituted includes the Bombycidie, Hemileu- cidae, Citheroniidie and Suturniidie. The antennte of the members of the grouj) may be separated by the following table : SATURNIINA. A. Pectinations ventral, single ])air to a segment BOMBYCID-^. AA. Pectinations dorsal. B. Single pair to a segment HBMILEUCID-^. BB. Two pairs to a segment. C. Distal portion of clavola filiform CITHERONIID^. CC. Qavola pectinate throughout SATURNIID.ZB. The Bombycidic are the least specialized of the Saturnians, and probably represent a branch which long ago separated from the one that produced the other families. The pectinations are well devel- 0})ed, but they are ventral, and there is only a single pair to a seg- ment. The pectinations are well sup[)lied with hairs of the third type, and the shaft also bears them for the width of the space be- tween the bases of the pectinations. A rather unexi)ected fact is that the antenme of the female are nearly as well developed as those ANTENNAE OF LKPIDOPTERA. 43 of the males, while in most of the other Satuniiimi they are much less specialized. The Hemileuriche ('xliil)it a line of (level()i)mciit distinct from that of the Bombycidie ou the one hantl in having the pectinations dorsal instead of ventral, and from the Citheroniidte and Saturniidie on the other in having a single pair of pectinations to a segment. Thus it ap])ears that they belonged to the branch which produced the latter families after it had separated from the branch giving rise to the Bombycidce. The ('itheroniidie and the Saturniidie have followed the same line of development in that they botii have two })airs of dorsal pectina- tions to a segment. The first family has not progressed so far as the second ; its members do not have their antenme pectinate throughout. The antennte (}f these families show a high degree of roximal.. .Coloradia. CC.

Distal ])air of pectinations of female longer than the proximal on the imtximal segments Philosamia. There is a gradual progression in complexity of development from Colomdia on the one hand, to Samia or Philosamia on tlie other. The females of Coloradia, Automeris and Callosaturnin, have a sin- gle pair of pectinations to a segment, while those of the other genera have two pairs. The males of tlie first two geuera have the distal pair shorter, while the other have the two pairs subequal. There is also a gradual increase in both sexes from one end of the series to the other in the number and position of the cones. In Samia there is not only an abiuidauce on tlie shaft, but many are on the pecti- nations of the distal portion of the clavola. There is some doubt as to whether S-tmia or P/ii/o.'i titynns, Fig. 4, our most common large skipper, does not occur in all forms. Megathi/inan yiuxtt, another ski{)per of about the same size, but belonging to another family, lacks the hook, and there is only a slight curving of the end of the clavola, not more than is seen in some of the butterflies. In such forms, however, the ventral expansion is a feature which distinguishes them from the Papilionina. The Papilionina includes the Pajjilionidie, Pieridic, Lycsenidie and Nym})hali(Ue. The Papilionina' rei)resents one line resulting from a dichotomous division of the stem-form of the Pai)ilionina, and the three other families represent the other. The members of the sub- family Papilioninie have developed a type of antenna quite different in some respects from that of the other forms. This confirms one of tiie most important changes made in the older classifications ])y TRANS. AM. EXT. SOC. XXIII. MARCH. ISyb. 46 DONALDSON BODINE. that of Professor Coiiistock — the separation of the Pieridie from the Pupiliouidse and association of them with the Nymphalidse and Ly- csenidre, while the Papilionidse are left standing alone, except for the few almost archaic forms representing the Parnassians. Instead of scales and pits along the clavola as in the Nymphalidre, or scales alone as in most of the members of the other families, there are in the Papilioninre no scales distad of the first segment of the clavola, but there is an abundance of short hairs or rods which no doubt serve as sense organs, and possibly serve to compensate for the scar- city of well-developed pits of the usual type. The sense organs are scattered over the whole surface of the clavola with considerable regularity, and the lack of scales is doubtless due to their large de- velopment. In the Parnassiime we find the same short hairs or rods, but instead of extending over the whole surface of the clavola, they are confined to a more limited area along the distal portion. The Parnassians are doubtless nearer the stem form of the Papilionina than are the Papilioninse. There are only four species, comprising a single genus, in the fauna of North America, and from their gen- eral structure they are regarded as a not very highly developed group. They have a thick covering of scales over the clavola, at least on the dorsal aspect, but the presence of the short hairs allies them to the Papilioninse and separates them from the other families of butterflies. The antennae of the Papilionidse, then, indicate that they are distinct from the other butterflies, and that they are less highly specialized. I am unable to find any definite characters in the antennje them- selves which are constant for the separate families, and which will separate the Pieridre, Lyca?nida3 and Nymphalidte. The Pieridie, however, differ from the Lyctenidse in the insertion of their antennae. In the former the antennjie do not infringe upon the eyes, while in the latter family, at least, the sockets do encroach upon the eyes. The Nyraphalidae have the most highly organized antennae of all the butterflies. They are abundantly supplied with well-developed pits. The clavola has pits upon the ventral surface even to the proximal segment in some forms, and there are other indications that these forms express the highest antennal development among the butterflies. It would perhaps be futile to compare the antennas of the skip])ers and butterflies with those of the moths. There is a wide difference between the structure and the organs of the antennae of two such ANTENNAE OF LEPIDOPTKUA. 47 extreme forms as Satnia cecropla ami EuvdHexm antiopa, but that each is best adapted to the other structures and to the life habits of the possessoi", and is most efficient in supplyin^j the needs of its ex- istence, is perhaps un(|uesti()ned. Samia cecrojna is chiefly nocturnal ; even in closely allied diurnal forms, such as Callosaviia promdhea, vision a})pears to be of little service as a j^uide to the motion of the moth ; and in such forms \\c find a higher degree of development in pectinations which bear an abundance of long sense-hairs of the third type. Eiivanessa and the skippers and butterflies in general ajDpear to have excellent vision, and in no case do they have pecti- nations or sense-hairs of the third type. The pits and rods, how- ever, which are common to all families of the LejDidoptera, reach a higher developnient in Euvanessa than in Samia. We may assert, then, with a fair degree of confidence that the antennae of the but- terflies are more limited in their functions, but that within the limits of their scope they are more efficient. SUMMARY. The character of the subject of this thesis makes it difficult to sunnnarize the results of th(^ work. The niore important features, however, may be noticed under the following numbers: 1. jNIuscles in the head move the scape ; muscles in the scape move the pedicel ; distad of the scape no muscles have been demonstrated, and the clavola is therefore capable of motion in itself only when acted upon by some external force causing a flexure and a subsequent extension. 2. Besides organs for protection, there are at least six types of sense organs situated in the antennae, and all but one are developed from a simple sense-hair inserted at the ectal end of a pore-canal through which it is connected with a multinuclear sense-cell. 3. The antennae doubtless function as sense organs of touch, smell and hearing, altliough those senses are not subject to the same limi- tations as in the higher animals and may be considerably diflerent in their range of perception. ' 4. T!ie antenme show that all Lepidoptera are descended from one primitive stem form, of which we may preilicate the more essen- tial features of structure. 5. The evohition of ventral expansions, of pectinations, of the chitinous surface, of the sense organs shows an increasing differen-- tiation of structure following the demand for increasing specialization of function. TRANS. AM. ENT. SOC. XXIII. MAECH. 1896. 48 DONALDSON BODINE. n. In the more essential features, the evidence of the antennae of all the families of the Lepidoptera confirms the provisional classifi- (jation based upon the wing structures, though in a number of cases it indicated a change in the relationships of some of the families. These arc indicated in the chapter on the discussion of the families. CONCLUSION. The work carried on upon the antennte of the Lepidoptera proves that these organs are worthy of more extended study. Aside from the great interest which attaches to them as the most specialized sense organs, their value as records of the descent of families is very considerable in taxonomic work. In the determination of the I'ela- tionships of the larger groups, they do not furnish as good guides as some of the larger organs, for while they are subject to great varia- tion, they do not afford a sufficiently large basis for variation to leave a stable and constant ground-work for the tracing out of the patlis by which the specializations are brought about. As supple- menting the evidence of the wings they are valuable. This thesis has dealt only with the relationships of families and superfamilies, but there is a large field for work within these groups, and in many cases the antennre will be found most important in taxonomic work. Owing to the difficulty of observation and the necessity for especial preparation, they afford few characters which would be practicable for recognition characters in ordinary systematic work, but for the more careful and painstaking work of the study of relationships they are of great value. BIBLIOGRAPHY. The following is a pretty complete bibliography of the subject of the antenme of the Lepidoptera. Most of the works referred to are upon the histology of tlie organs, or upon the question of the })hysio- logical signilicance of the antenuiie. So far as I have been able to discover, nothing has been done with the comparative study of dif- ferent families. A few of tlie works given have not been at my conunand, and they are given from references made to them by other authors. Alpheraky, S. — De Tolfiiction chez les Lepidopteres. Bull. Soc. Ent.

AMERICAN IIYMENOPTERA. 85 A MONOGRAPH OF THE GEXIJS SYIWEROUS Haitig. BY C. P. GILLETTE. I find ill the college collection, as a result of our rearings for the past three years, a considerable number of Synergus species, some of which are new to science. As I have the original descriptions and also representatives of all the North American species, and as many of the descrij)tions are inaccessible to students of Entomology, I have concluded to bring together, in one paper, descriptions of all the species, with au epitome of our present knowledge in regard to their habits. Ill this connection I wish to thank Mr. W. H. Ashmead who has, in past years, determined several species of Synergus for me, and who has sent me types of those species described by himself. The members of this genus are all Intpiilines, or guest-Hies, in- habiting the galls of the oak-infesting Cynipidse. Although true parasites, so far as the gall within which they develop is concerned, they are not parasites in the ordinary acceptation of that term as applied to insects, as they do not attack the true gall producer. They are vegetable feeders and not flesh consumers. Tiiis genus is not a large one as at present known in this country. In Europe there are 31 described species of Synergus, while, includ- ing the eight new species in this paper, there have been but 24 spe- cies described from North America. As yet none of these 55 species are known to occur on both sides of the Atlantic. The bibliography given in this paper is largely copied from Dr. De Dalla Torre's " Catalogus Hymenopterorum." SY!VEROUS. Hartig:, Zeitscbr. f. Eiitmn. ii, 1840, p. 186, n. 13. This genus is readily se})arated from all other Hymenoptera by the closed marginal cell of the wing, the coarsely striated face, the fluted petiole and first abdominal segment, and by the large second abdominal segment, which occupies nearly or quite all of the abdomen. The species may all be separated into three natural groups as follov.'s : Antennffi of feinaU' 1.3-.jointec] Group I. AntPiiiia' of female 14-,joiiitcd Group II.

Without close examination this species would be taken for small individuals of Siiiirrgii>< mmpanida O.

Baron Osteii Sacken did not know the galls IVoni which he ob- tained his specimens. The specimens in my collection I bred from Avoody twig galls taken at Lansing, Mich., on red oak and no true gall-tiies were reared. The flies issued in large numbers and vary much in color, especially in the females. The females also vary from one and a half to three mm. in length. The darkest of these show a slight rufous coloration only on the lower portion of the face, about the eyes and a small spot in front of the tegulse ; light ones have the whole head, except a dark spot on the vertex, the neck, and a large space on the shoulders, bright rufous as in the males. This species is quite close to lignicola O. S., but differs from that species in having a very coarsely transversely Avrinklcd mesonotum. SyiK'd'giis bi(*olor Ash. Si/nerfjun bicolor Ash., Trans. Am.

From Walsh's description of" rhoditiforinU, which he acknowl- edged to be only a dark form of Ivjuicola, we learn that the anteunje in the male is 15-jointed, and that the last joint in the female an- tenna is once iind a half the preceding, and also that the mesonotum in dark specimens may be entirely black. Osten 8acken, in his synopsis of the s{)ecies oi' fSifncryus in volume iv, of the " Proceedings of the Entomological Society of Philadel- phia," J). 378, says that the fourth joint of the female antenna is hut little more than one-half the leuirth of the third.

I have four type specimens of this si)ecies sent me by Mr. ^Vsh- mead. There is, evidently, a ty})()graphical error in the original description, for the three females in my possession all have 13-jointed antennae. Like other 13-jointed species the third joint is nearly twice the fourth in length. The sides of the second alxlominal seg- ment are without punctures. S[)ecimens of lignicola in my possession, which were also sent me by Mr. Ashmead, and which were bred by him from the galls of A)idvk'H>i cornigera, enable me to separate this species from >nedalke as Ibllows : The parapsidal grooves are much more distinct in ligni- cola than in medulla' ; in the latter species the antenna is very short, hardly reaching beyond the middle of the mesonotum ; in lignicola they are decidedly longer, easily reaching the scutellum, and the terminal joint in the female is unusually long, fully as long as the third. In the males, the last joint scarcely, if at all, exceeds the preceding in medullce, while it is nearly twice the penultimate joint in lignicola. I also notice in my specimens of female medulke that in no case do the ovipositor sheaths project from the second segment, while in lignicola they arc considerably protruded and directed upwards.

Five males of this Western form have the thorax entirely black in every case, while a single male from Ottawa, Canada, the only other male that I have seen, has the thorax black, except a narrow margin on the propleurie. Judging from Harris' description, it seems probable that his speci- mens came from galls of Holcaspii (jlobulns, and it is from this gall that Fitch and Osten Sacken obtained their specimens. My speci- mens were bred from galls of Cyidps strobilaiia 0. S. both in Mich- igan and Iowa, and from galls of Holcaspis rubens Gill, and Dryo- j)li entirely aciculated, black. Abdomen yellow, with a shining black blotch or dorsum, densely punctured on posterior one-half of second segment ; this segment somewhat incised on dorsum, exposing the following segments (in one example the third and following seg- ments are retracted under the second and the ovii)ositor slieaths are left standing out away from the alidominal segments), ovipositor sheaths attaining the dorsal line. Feet light honey-yellow, except as mentioned above. Length 2.75-3.5 mm. Described from four females bred from the galls of Holcaspis hrevipennata Gill, from ISIaiiitou, Colo. This species is separated from oneratm O.

Hence it would seem that this species is not double brooded like keviventrls." Mr. Cresson, in his " Synopsis of the Hymeuoptera," etc., pub- lished in 1887, make this species .syuonymous with laiue Fitch, which I think is a mistake. In laiue the head, except the vertex, is straw- colored, while in albipes it is all black ; in kuue the second abdominal segment does not completely cover the succeeding, wdiile in albipes it iloes ; in lance the females are 15-jointed, while in albipes they are but 14-jointed. I have both species in my collection, and they are very distinct.

LENG, B.S., WITH NOTES AND DESCRIPTIONS BY JOHN HAMILTON, M.D. After spending much time and bestowing much labor on the present work, Mr. Leng was compelled to abandon its further prosecution by causes beyond his control. All work done was placed in the hands of the writer to use as might be thought best. Mr. Leng had the paper prepared for the press as far as Leptostylus, and that part is published from his manuscript. From Leptostylus onward the most of the tables, bibliography and distribution, were furnished by Mr. Leng. What renuiined to be done was the completion of these and the furnishing of descriptive notes under the species ; this is represented in the text by the matter inclosed in square brackets. The writer is responsible for all following the close of the synopsis proper, being notices of synonymy and species introduced or described since 1884, the date of the commencement of the synopsis of the Cerambycidte. As this paper is likely to fall into the hands of many who have not. access to detailed systematic descri[)tions, to make it useful to such the salient features of each species are given, being taken from the insects themselves, except when not obtained. John Hamilton. Allegheny. Pa., March 18, 1896. Preliminary Remarks by Mr. Leng. Since 1767, when Linne described Lagocheirti^ araneijormi^, the number of our Laniiinie described has continually increased, and owing to the scarcity of the books containing them, the descriptions are accessible to but few students. The object of the present paj)er is to bring together these descriptions and thus complete the series conunenced some years ago in the Bulletin of the Brooklyn Ento- mological Society. All the genera containing numerous species have been recently treated in synoptic form by Dr. Horn, and they will therefore be but briefly copied here. For a more detailed study the reader is referred to the original papers, viz. : " Notes on some genera of Cerambycidse of the United States," Trans. Am. PCnt. Soc. vii, TRANS. AM. ENT. SOC. XXIII. MARCH, 1896. 102 , LKNG AXT) ITAMFT-TON. 1878 ; " Notes on some genera of" (Jeranibycidte with descriptions of new species," Trans, viii, 1880 ; and " Descriptions of some new Ceranibycidse with notes," Trans, xii, 1885. In tlic stndy of this sul)fainily tlie specimens that accnmnlate dis- j)hiy ditferences in color, in punctnation and in vestiture, tliat do not always indicate specific difference. Tlie influence of climate and of the food-})lant is very marked, and the variation thereby occasioned has led to the description of some species that are now considered races or synonyms. Where slight difference in color, etc., accompany difference in food-plant or locality I have considered them indicative of races ; where these differences, though they may seem of consider- able import when only two extremes are compared, are connected by intergrades I have considered them as indicative of individual variation. Should the reader possess only the two extremes, I beg him to believe that the intergrades, nevertheless, do exist. It is a pleasure to acknowledge the assistance I have received from Mr. Frederick Blanchard and Dr. John Hamilton, to whom I owe many of my specimens; to Mr. Samuel Tlenshaw, who has revised the lists of localities given ; and to Dr. Horn, who has allowed me to use his collection and library, and, in addition, has given much advice throughout the paper.

This species, described from a single male, is stated to differ from lepidus in having the pronotum in front of the coxie strongly de- pressed and coarsely densely punctato-rugulose ; in lepidus this space is divided by a polished longitudinal elevation, thus forming two depressed areas. Xylotreclms gemellus Casey, 1893, An. N. Y. Acad. Sci. vii, 590. Length 14-15 ram. = .54-.60 incli. Habitat. — Indiana. Described from two examples and represented as differing from undulaUis chiefly by the coarser sculpture of the pronotum, suffused pale pubescence extending across the base of the elytra and less prominent frontal carina ; the transverse bands different in form, being wider and posteriorly arcuate at the point where, in undalafK.^, they are anteriorly angulate. The individuals of undulatus vary greatly in coai^seness or fineness of sculpture, in })ubescence, and in distinctness of the elytral bands, and none of the differences mentioned by Mr. Casey seem of any value, unless it be the last mentioned. Cijrto])horus insinuans Casey, 1898, An. N. Y. Acad. Sci. vii, 590. This is the male of Micvodytus gazellula. The description was made from a unicpie taken in Ontario, Canada, with the statement that it only dilfered from Microclyfus gazellula by having the third antennal joint briefly dentato-spinose. The five males of that species before me all have rudimentay den- tations at the apex of the third joint, and a little amplication of this most probably exists in Mr. Casey's uni(iue. The antennal cliaracters of Mlcrochjtus in the " Classification" belong to the^ female ; those of the male, then unknown, are the same as in Cyrtophorus, exce})t in the less or non-develoi)ment of the antennal spine.

This is synonymous with sexnotata, which is quite variable in color of the legs and antennae and in coarseness or fineness of the punc- tuation. The truncation of the female elytra at tip is relied on by Mr. Casey to separate it from sexnotata, but in a sufiiciently large series, the tip will be seen to vary from acute to truncate, especially in Western examples.

When two forms are in dispute spetMlically the (leHnite way of determining \vhether they are distinct or not i.s to observe if they interbreed. This means, oftentimes, a long delay in confirming the validity of species after new discoveries are made. We can, iji the absence of such proof, resort to the systematic study and comparison of characters. The breaking in on the attending series of evolutionary changes in nature allows, by induction, a dis- tinction to be made of species by the exclusion of inconstant varia- tions of structure. A large series of specimens of a common nj)ecies of grouse locust will illustrate, viz. : 1. A generation of individuals closely resembling each other, but with structural peculiarities mani- fest as slight departures in each specimen from the parent ( individual variation); 2. A group composed of examples in which slight, but similar lines of departure of structure occur (varieties) ; 3. Another in which analysis confirms progressive fixation of structure (insipient or sub-species) ; 4. Lastly, stronger though variable structural pecu- liarities recognizable as common characters (species). Besides, tiieri' are atavic; dimorphic forms which are subordinate to si)ecies. The advent of modern discussions in evolutionary doctrines has made it particularly important to note the differences or plasticity in the or- ganism. The contention that constant structural j)eculiarities be used in separating species leaves out those forms falling under the classes one to four. There has been a notable indifference to the grouping and characterization of species now in tlie actual process of evolving as in those outlined above. In the interest of advancing'- scientific knowledge their consideration is of much interest. Where mention is made of " species" is this group, the Tettigidie, we are a good way along in permanency of characters. The great degree of variation occurring in the grouse locusts is well known. In so shoit TKANS. AM. KNT. SOC. X.Xiri. JULY. 1»96 230 J. L. HANCOCK. a paper we must leave the subject of tlie stages leaciing up to their origin to be considered at another time. Some earlier naturalists separated species on the ephemeral " color characters." As remarked by Uhler and more recently reaffirmed by others, they are practically of no classificatory significance. It is on the whole but proper to speak ])rovisionally where variations are such a constituent part of the organism that we no sooner are desirous of immortalizing our iype than forces of evolution mold or modify the characters by changing the lines of configuration in the monument raised in its behalf. Such is a picture of the Tettigidse. Members are to be received tentatively until a careful revison is formulated after the descriptive stage has been completed in our North America forms. With reference to the general classification of the grouse locusts, the excellent special essay by Bolivar,* aside from containing some confusing statements on North American forms already noted by Morse, is the most comprehensive work published. The absence of pulvilli between the claws, the shape of the pronotum, which extends backwards like a roof over the wings, often extending beyond the end of the abdomen and the small loboform wing covers (elytra) distinctly defines the group. To Brunner De Wattenwyll entomological science is indebted for elevating the knowledge of the general relations of the Orthoptera to a much higher |)lane. In his " Revision, "f page 102, this grouj) is placed as the first of nine tribes constituting the orthopterous division Acridiodie. The current bibliography in America is replete with interesting [)apers. Especially noteworthy are articles by A. P. Morse, which, besides giving biological notes of merit, also note descriptions of new North American species. The writings of this author include a synopsis of the Tettigid?e in " Notes on the Acrididie of New England" " Psyche," October, 1894, and a serial paper (two articles) on "New North American Tettiginaj" in Mar(;h and Sep- tember numbers of the journal New York Entomological Society. Jerome McNeill has contributed some valuable notes in " Indiana Orthoptera," "Psyche," 1894. W. S. Blatchley has enriched the literature in a serial pa[)or under the title of " Indiana Acrididie" iu " Canadian Enton\ologist." * Essai sur les Acridiens do la tribu des Tettigidse (Ann. de la Soc.

That portion of northern Illinois known as the Des Plaines, and a part of the Calumet River region in Cook County, formed the central focus of observations. So far recorded this grouj) of locusts as found here is given in the accompanying list ; a number are new. Among speci- mens from M. J.

As tlie result of" the work of systematlsts, two methods of ckissifi- cation are found in our lists and text books. The first is in eonnnon use in iMirope, and is the system of Lederer. The second is in use in America, and is the system of Guenee. Lederer's system, pub- lished in 1853, was far in advance of anything published before him, and, as based in large part upon structure, has deserved the respect it has always received. Guenee's system was given a life on this side of the ocean by the fact that Dr. Packard, in his Monograph, closely followed it, and that Monograph has made our lists and given us our names. This system, professedly attempting to cover every- thing, is exact in nothing, and as a system is absolutely without worth, and, apart from Dr. Packard's following, has never had any recognition. In 1892, Mr. Meyrick pul)lished a "Classification of the Geome- trina of the European Fauna" (Trans. Ento. Soc. London, 1892, part 1, pp. 53-140), in which he endeavored to arrange the family on the basis of invarial)le structure. This classification does not as yet seem to be adopted, but is, in many respects by far the best yet proposed, and is the result of wide comparative study and consistent generalization. It is this system which, in the greater part, I have followed. And yet I have made in one respect at least a radical departure from it. Mr. Meyrick lays down as one of the funda- mentals of his classification the following rule : " No genus, family or higher group, is tenal)le unless distinctly separable from all others by points of structure, which, whether singly or in conjunction, are capable of accurate definition. If a systematist is not able to define by a clear and not simply comparative character, the distinction between two genera, he is bound to merge them together." This rule is a most excellent one, but Mr. Meyrick, in his rigid and con- sistent application of it, gives it an interpretation not warranted in [)ractiee, for he makes not difference in structure, but difference in TRANS. AM. ENT. SOC. XXIII. JULY, 1896. 246 GEORGE D. HULST. structure without tlie known existence of intermediate forms in nature, to be the application of the rule. As a result some of his genera cover almost subfamily differences, as witness such as Pseudo- panthera and Crocota. All divisions are artificial in theory, and accidental in fact, and it is more natural, and it seems to me more scientific, while using discretion, to consider wide variations in structure as valid bases for genera even though intermediate forms may exist which may be referred with equal propriety to one or to the other. I have also given more importance to some details of structure than is given by Mr. Meyrick. As an example, my own experience leads me to regard the pencil found on the hind tibiae of the males of many species as a thoroughly reliable point of structure. It may often be rubbed off, and the groove in which it rests be difficult to discern, but the structure is not variable in the same species. There are other structural peculiarities which may modify classifi- cation in the future. Some of these may be found in the larval and pupal stages, but, apart from what I have noted, nothing has as yet been observed which seems reliable. A character in the imago which may be of greater importance than I have given it, is the peculiar form of the subcostal vein of hind wings near the base. Prof. Comstock, who discovered this peculiarity, makes it of family im- portance. My own observations lead me to believe it cannot be considered exclusive. First, it is scarcely distinct in some of the Sterrhinse, and is wanting in some that we must consider true Geom- eters such as the genera Mccoceras, Melanchroia, etc., as well as some genera of the Monocteniinae and Strophidiiuaj. On the other hand the tendency to the basal angulation of the costal vein of the hind wings seems to me to be as fully developed in some of the Geometri- form Noctuina, as in the Sterrhiiuie and Monocteniinte, and much more so than in some other genera. In some of the Catocalce this angle is clear, though it is apt to be overlooked, as the vein is very faint, while the vein, which would be vein 9, and which is coincident with 8 just beyond base is very strong, and is ordinarily regarded as the only one. Very considerable use may in the future be made of modifications of the antennae, based on a form of structure, so far as I know, not hitherto observed. In the species which have the antenuie bipecti- nate in the males the position of the pectinations with regard to the segments upon which they stand is very different. In a very few AMERICAN LKPIDOPTERA. 247 (Tiipulu) the anteniue are doubly bi})ectinate, having two pectina- tions at tlie summit and two at the base of each segment ; this is also the case with the pectinate species of Erannis, a fact not here- tofore noticed. In many species the pectinations are at the summit of the segments, and in others at the base only. This tendency is shown in the species which do not have bipectinate antennae, as well as in the females, the tend('n(;y of the ciliations being to gather into tufts at both suiiiiuit and i)ase as in K('tropl><, etc., or at bottom, or at top oidy. 1 have not been able to make any exclusive generali- zations as y(;t, but the Sterrhinie seem thus to separate from the Geomctriiuc, the former having the pectinations at the bottom, the latter at the top of the segments. In the Ennominie the species having the pectinations at the top of the segments generally corre- spond with those which have the fovea at the base of the fore wings in the male, but this is not always the case. A few species have the antennie serrate, and a few others have them flattened and more or less lamellate ; generally with this structure the antennjc are naked, at least below. I have found only one instance of unipectinate an- tennse among our species, and this is the 9 of Gonodontis hijpo- chraria H.-Sch., but I am not sure that any emphasis can be placed upon this fact. In most species the pectinations on one side are shorter than on the other, and in this species in the female the longer pectinations have apparently just begun, or are just losing their existence, while the shorter ones have not begun, or have ceased to be. There are also very considerable differences in the position and shape of the tibial epiphysis. In many species it is below the middle of the tibia and short. In others it is above and often reaches con- siderably beyond the end of the tibia ; sometimes it is considerably tufted. The tarsi vary considerably compared with the tibite and witli each other. They are often spinulated, sometimes strongly so. These characteristics, so far as my observations go, are compara- tive only. I have as yet not been able to make use of them in clas- sification, but suggest their variability that the future student may make use of them as a larger and better study of material may warrant. I have been able to make nothing of the ocelli ; other students have seen them in a few species, but I have to confess I have never yet seen the organ developed in a single Geometer, though for the purpose of study I have bleached hundreds of heads, and in some TRANS. AM. ENT. SOC. XXIII. JULY, 1896. 248 GEORGE D. HULST, species for this very purpose. In a very few cases, however, I have found the minute rudiments of maxilhiry palpi. I have endeavored to follow strictly the law of priority in generic and specific names, and have therefore, without hesitation, taken Hiibner's genera as given in the Verzeichniss. I have not endorsed the names of the " Tentamen," as I can find nothing which shows it to be a publication. It is simply a printed letter, and can have no authority, because it was written in type. I have, however, noted where the " Tentamen" names apply, for the convenience of those who disagree with me in my opinion of their validity. I have been unable to make very little of the genera of Guenee and Walker, based upon exotic, mostly tropical material. Their diagnoses are in the main without exact reference to structure, and I have been unable to examine their types. I have also made little use of the genera of some later writers, as the structural basis for these genera is the position of various veins which is excessively variable in the same species. The validity of these can only be de- termined after extensive comparison of structure in the same species, and in species nearly related. It was the custom of the French Lepidopterists of former times to call the group the Phalsenidse, and in this Guenee was followed by Dr. Packard In his Monograph. Phakeiia, as used by Linnaeus, is nearly equal to the Heterocera as now used. Geometer was the name he gave to group under consideration. Fabricius afterwards ignored this name, and called the group Phahviia, but it is clearly a synonym, and so neither it nor its derivitives have any standing. I have given the group superfamily standing, though the most of systematists may not agree with nie. But as will be seen I give the group a wider reach than most Lepidopterists. The Geometrina separate from other groups of the Lepido})tera as follows : The antennae are never club shaped or fusiform, and they are thus distinguished from the Rhopalocera, Spliingina, and some other grou])s. The larva have one or more pairs of the anterior abdominal legs wanting, and they are thus distinguished from the Bombycina in the widest reach of that term ; vein 5 of the fore wings is from or near the centre of the outer margin of the cell, and they are thus distinguished from the Noctuina. There are only one or two internal veins to the hind wings, and thus, as well as l)y the peculiarity of the larva', they are separated from the Microlepidop- tera. In my judgment their nearest relatives are the Noctuina, AMKKU'AN LKIMDOl'TERA. 24i) though in this opinion I have the sympathy of very few, W, indeed, of any otlier Lepi(h)pteri.sts. GEOMETRINA.

Hind wings with lines corresponding to the fore wings, but less distinct, becoming obsolete towards base, and with interspaces more uniform light fuscous, except that the lines have a dark outer shading. Female varying in colors of thorax and abdomen from light gray to dark fus- cous, the thorax being the darker, at times almost blackish, and the abdomen .sometimes annulate with gray. Wings gray, with a deep black band beyond middle. Described from four males ami five females, one pair sent by Prof. Fletcher, the rest from Mr. W. H. Danby, all of these taken by Mr. Danby at Victoria, Brit. Col., from early in November to about middle of December. The females seem to vary considerably in size, some being hardly larger than the $ of Raehela bruceata, while others are almost as large as the 9 of Erannis tiliaria. The spe- cific name is given in honor of its discoverer, Mr. Danby. 7 RACHEL A n. gen. Type bruceata Hulst.

R. occidentalis n. sp. — Expands 32-34 mm. I give this name to an insect of which I have received many specimens from Victoria, Brit. Col. It is very uniform in appear- ance, and without doubt nearly related to R. bruceata. It is, how- ever, in the % uniformly darker on all wings, and the fore wings have the apex more rounded and the inner margin shorter. The inner angle is thus broader and the wing more oval in shape. The 9 is blackish gray instead of fuscous. R. latipennis n. sp. — Expands 28 mm. I give this name to a species received from California, of which I have no females. The wings are much broader than in R. bruceata or latipennis, and the apex much less extended. It has much the same markings as bruceata, but they are more decided in color the lines of the hind wings being especially pronounced. In general appearance it approaches Opheroptem bruniata of Europe. R. hyperborean n. sp. — Expands 23 mm. Very much in appearance like E. luHpennia. with narrower wings, the two outer lines quite distinct, the central band obsolete, and the vestiture more hairy, and uniformly of very much smaller size. I suspect this may be a subarctic form of R. bruceata. My speci- mens of R. hyperborea are all from Alaska, and are very uniform in size and appearance, and are all smaller than any specimen of R. bruceata I have ever seen. HYDRIOMIN^. The Hydriominje are, with the Dyspteridina^, in the main very easily and clearly distinguished by the peculiar anastomosing of vein 8 of the hind wings with the cell. The exceptions, where the vein is separate, but joined by a cross-bar beyond the middle of the cell are peculiar, but can in no wise be made another subfamily as the females are normal. As noticed by Mr. Meyrick the most of the species with this peculiar structure have the inner margin in the S with a fold or pocket, and the anterior part seems to be broadened and the anterior veins separated as a compensation. A second exception which, as has been seen, I have made a sub- family is in the case of a few genera where the frenulum is wanting. This I have called the Dyspteridime, from Dyspteris, the ty])ical genus. Another exception which I have j)laced with the Geometrinie is a genus of the "greens" which ditlers from this subfamily and agrees AMERICAN LKl'IDOPTKRA. 255 witli the Geometriiiie in the position of vein 5 in the fore and hind wiiiffs, as well as in other very important particulars. A final ex- ception is Fernaldella, which is immediately distinguished by the absence of vein 5 in the hind wings, thus belonging to the Ennomidse. The venation of one genus {Zenophleps) is very peculiar, 6 and 7 being stemmed and separate from 8 in the fore wings. It is close to the European genus Oititc/i/sme Hb., and I agree with Mr. Meyrick its appearance is due to the obsolescence of the posterior wall of the second accessory cell. It might very properly be made the basis of a separate subfamily. In the Hydriomiuie the tongue is with rare exceptions present. In the fore wings there is generally one inner vein 3 and 4 are separate, and 12 is free. The position and relations of veins 9, 10, 11 and 12 are very uniform and unvarying. In the hind wings 3 and 4 are generally separate, and H and 7 stennned. In the description of genera the general form is understood, unless otherwise noted. HvDRIOMINiE. Synopsis of Genera. 1.

Mr. Meyrick calls this genus Erannis Hiib., but it seems to me incorrectly. Hiibner's genus Eranim has four species under it, three of which, and these are the first in order, are congeneric, and therefore typical of the genus, and there can be no question this was his intention. DefoUnria is the type species ; another genus of Hiib- ner, Alsophila, has as its type (escularla Schif., and this is congeneric with the fourth species under Enmnis. There can be no doubt as to the application and limitations of the two terms. Latreille ap- plied the name Hi/herniIIII.<>1>SIA n. gen. Type mvi(jenita Walk.

A very common, iind perhaps the most remarkable of these, is the tendency of the hind legs to obsolescence, in part or as a whole. The spurs are often partly or altogether absent. Some- times the hind tibine are largely developed with heavy hair pencil in the males, the tarsi being much shortened, and again the wliole leg is sometimes practically obsolete in the males. The development seems to have been as follows : The hair pencil has developed on the hind tibite, and, with its increased develo[)ment and use for orna- mentation, the spurs and tarsi have been absorbed, so that the hind legs have become useless for their normal purpose. A change of development then seems to have taken place ; the pencil has been gradually aborted, and the leg being useless for its normal purpose has tended to become obsolete. I have found no instance where the leg is absolutely wanting, but there are many where it is very de- cidedly reduced. This tendency, also shown auiong the Geometrinse, is, so far as I know, unique among the Lepidoptera. In this family the tongue is always developed, the fore tibiae are never clawed, and the clypeus never tubercled. The venation of the fore wings is to an extent variable, but the number of accessory cells is rarely subject to variation. A peculiar feature is the ab- normal and deltoid development of the })alpi in a few species. Of the typical genus Sten-ha Hiib., of which Acidalla Treit. is a synonym, I have as yet found no representative in our fauna. STERRHIN^. Synojisis of Genera. 1.

They consist of the same simill frail insects, with the same aspect, and with, in the main, the same structure. They are, however, gener- ally easily distinguished by their color, which has given them the designation " the greens." While the Sterrhinae approach the char- acteristic venation of the Geometriuie, there is no difficulty in sepa- rating them by the position of vein 5 of both wings. These sub- families seem also to divide on the structure of the antennje. So far as I have examined the antennse of the species, which are bipec- tinate in the male, those of the kSterrhina3 have the pectinations situated upon the bottom of the segments, while those of the Geo- metrintie have them upon the top. The Geometrina' hav'e the same tendency towards the obsolescence of the hind legs already noticed in the Sterrhime. The larva', so far as known, are characteristic and peculiar. They are furnished with [)rotuberances on the segments, anil have, to some extent, the habit of covering themselves with debris of leaves, thus more effectually concealing themselves. The family as limited seems to include more specialized forms of other subfomilies. Among our species, apart from the characteristic venation, there are found some with the distinctive venation of the Hydriominse, some with that of the Sterrhime, and some with that of the Ennomina). They make distinct sections of the subfamily, and I am not entirely sure but that the genus Annemoria would better i)e placed with the Hydriominse. The subfamily is mostly tropical, and our si)ecies are few and rarely plentiful. I sus|)ect that some of our genera will be found identical with others described from tropical material from l)()th hemispheres, but nothing definite can l)e determined till ty[)es are examined and com- pared, which I have not had the opportunity of doing. The typical genus Geometra I have not found in our fauna. Anaplodes is very TKANS. AM. ENT. SOC. XXIII. SEPTEMBR, 1896. 312 GEORGE D.

Under Alxoph'da I have sj)oken of the application of the generic term Krantils. It cannot be a])plied to the s])ecies ordinarily grouped under Aiiisopteryx Steph. as they belong to Hiibner's genus Also- jj/ii/tt. The only proper application is to regard defoliaria as the type of ErannU, as this was beyond (piestion the idea of Hiibner. The species ordinarily grouped together in that genus I do not l)e- lieve to be properly congeneric. Apart from other things there are great differences in the antennie of the males, the majority having the antennte bipectinate and so decidedly different from the antennae of E. defolidfia. Hybenda Latr. if not regarded as a synonym of Erannis, must stand for the species with bipectinate antennae in the % . But that group had already been called Agrilopl.-< by Hubncr. Our species are all of the defoliaria group. Species. — E. defoliaria var. vancoiiverensis Hulst. E. filiaria Ilarr. E. coloradida Hulst, n. sp. E. defoliaria var. vancouveren-sis n. var.

Mr. ^leyrick joins CrocalUa Treit. with this. The type of Cro- ealll.fi is eiuigaarla L., which is also the type of Easarca Hub. of the Teatamen. Eiiiu/uarla is not congeneric with Gonodontis how- ever, as the tongue is wanting. I have joined with this genus Epir- miif/n's Hiib., the type of which is vbjinnaria Hub., which has broad, rounded wings, but which is insensibly connected with the species having waved or angiflate wings. Mr. Warren gives the name Mdarrhauthla to obfirmdrla, " because pidverata has been re- moved to the Orthostixinpe." Epirratdhlf was created by Hiibner with two species under it, palvemtu and objinnaria. Boisduval, find- ing tiiem not congeneric, created the genus Ploseria with piifvcnita as type, thus leaving objinnaria as type oi'-Epirranthitt. This was right, and the reference was, so far as I know, universally recognised by systematists till ^Ii'. Meyrick, without explanation, \)ut pnlce rata under Ejjirraidhif<. 1 do not believe Epirraid/ii-i a valid genus, but if so or not, its type is objir nutria Hub. Hiib. Verz. 268, 1818, gave the name Gonodoida to a genus of Noctuidte. Under the })resent recognised law of priority, the luime Gotiodoidifi, not being a mere distinction of gender, is not a syno- nym, and must not, therefore, give way to Epirraidhis.

This subfamily had always been regarded as Lithosian till its larva was discovered, which showed it to be a true Geometer. It is, how- ever, not typical, as the base of vein 8 of hind wings is scarcely bent, and is not angulated. The species are brightly colored, as a ride, and decidedly showy in appearance. TRANS. AM.

Since the publication of my paper on the Desinori of North America, the greater part of my spare time lias been devoted to a study of our North American Ceutorhynchini. To make these .studies as complete as possible I have also examined a large number of foreign," especially European species, representing, with one ex- ception (Mecysmoderes), all the genera of this tribe described by Lacordaire. Before proceeding to the elucidation of the subject proper, I desire to call attention to a few characters which, to the best of my knowl- edge, have escaped observation heretofore. The formation of the ventral segments presents certain modifications, of which I have made use in the classification of the genera. 1. The second ventral segment fully as long or longer than the two following segments together, the latter always short, the third segment not narrowed on the sides by a prolongation of the hind angles of the preceding segment. PI, xiii, fig. 19«. 2. The second ventral segment scarcely as long or shorter than the two following segments, hind angles prolonged, the prolongation in- tervening to a greater or less extent between the third segment and the lateral margin of the abdomen and showing thus a tendency to the Tychini. PI. xii, fig. 1. Another character, though of a sexual nature only, is this, that in the majority of the species the middle and posterior tibise (generally) of the males are unguiculate at the apex, while unarmed in the females, and occurs especially in the fir.st three subtribes. Aside from this last-mentioned character the sexes can, as a rule, be readily distinguished. The males have the beak stouter and less elongate, the antennae less slender and inserted nearer the apex (rarely the same in both sexes), and by the fifth ventral segment being subtruncate and frequently foveate. TRANS. AM. K.VT. SOC. XXIII. SEPTEMBER. 1896 388 WILLIAM G. DIETZ, M.D. Family CURCULIONIDJE. Tribe Ceutorhynchini. Beak variable, very slender, filiform in Mononychi, slender in Ceutorhynchi, somewhat stouter in Cceliodes, until in the subtribe Phytobii the beak becomes quite robust and short in some of the species. Scrobes lateral or infra-lateral, directed against the eyes, more rarely oblique and directed lieneath the eyes {Phytobii veri). Antennae generally slender, funicle G- or 7-jointed, club variable, from short ovoidal to elongate, acuminate. Eyes rather large, finely granulated, never closely approximate above, more or less concealed in repose by prothoracic lobes (except Phytobii veri). Head sub- coninal, occiput carinate ; prothorax generally wider than long, nar- rowed in front, with lateral tubercles distinct in almost all, postocular lobes more or less developed in all except Phytobii veri; scutel very small or not visible. Elytra broadly oval, convex, in the majority of species, more rarely elongate, generally distinctly wider at the base than the prothorax and separately rounded at the apex. Pygidium nearly perpendicular, exposed, larger in the males than in the females, with a transverse elevated line (except Mononychis), a continuation of the lateral margin of the abdomen and against which the apex of the elytra abuts. In front of this elevated line is a short carina. Prosternum canaliculate, the canal sometimes effaced before the an- terior coxte (Phytobii), of variable length in front of the latter, with or without antecoxal ridges, more or less deeply emarginate for the reception of the beak in repose ; mesosternum canaliculate or excavate in Mononychi and Qrliodes, declivous and entire in Ceu- torhynchi and Phytobii (depressed and transversely sulcate in liiley- onymus) ; side pieces wide, ascending between the prothorax and the humeral angle of the elytra and generally visible from above ; metasternum canaliculate in Moiionyehus (and some foreign Ofliodea), emarginate or excavate anteriorly in some Cceliodex and forming the posterior limit of the pectoral canal, entire in Ceutorhynchi and Phytobii. First ventral segment longer than the second and sepa- rated from it l)y a straight suture (see above); sutures 2-4 deeply impressed and curved backward on the sides. Fifth ventral seg- ment longer than either of the two preceding segments (except Rilexjonymus) ; anterior coxae conical, not contiguous, middle coxae rounded, entirely enclosed by the coxal cavities (open within in Rileyoiiymm) and generally more widely separated than the anterior.

Legs variable, generally slender, never very stout ; femora mutic or dentate, more or less clavate (posterior strongly incrassate in OvcJtedomeru>i) ; tibise very variable, acutely angulate near the base in Cuemogonm and CraponiuH, external apical angle of the anterior tibiie produced into a toothed j)rocess in Cne- mogou.as and Accuithoaceli^, the middle and posterior fre slender, first joint stout, short, second lonj^ and slender, and nearly equal in length to the three following joints united, club abrupt, large, first joint occupying more than one-half of its mass. Eyes oval, partially covered in repose ; prothorax transver.se, strongly narrowed anteriorly, surface uneven, (piadri-tuberculate, anterior pair of tubercles larger, obtuse, posterior smaller, acute ; base bi.sinuate, produced in front of scutel, latter very small, glabrous. Elytra suddenly wider than the pro- thorax and wider than long, humeri protuberant ; sternal side-pieces scarcely visible from above; prosternum long in front of the coxa?; pectoral sulcus deep, prolonged to the end of the metasternum. Ab- domen short, second ventral segment shorter than the two following together, prolonged at the sides to the fourth segment, the third not attaining the lateral margin ; sutures 3. and 4 deeply impressed, fifth segment about as long as the first; pygidium with ill-defined longi- tudiiuil furrow ; femora uot toothed, deeply grooved for the reception of the tibije, latter flattened, acutely angulate near the base, suleate along the external luargin for the reception of the tarsi, latter with the third joint very broadly bilobed, fourth rather short, claws armed with a slender tooth about half the length of the former.

Under this generic term I have separated from its near allies that heterogenous aggregation of forms heretofore known in our lists and collections as Coeliodes acephnlux and ciirtus. The formation of the ventral segments at once separate it from Gdiodes, which, indeed, it resembles very little in general habitus. Its nearest relative is Cnetutxjoii ((.•<, witii which it agrees in the pectoral canal not extend- ing beyond the mesosternum and in the presence of tiie apical pro- cess of the anterior tibite, and from which it difiers in habitus and the absence of the acute tooth near the base of the tibiae. The beak is moderately stout, nearly straight, shorter and cylin- drical in the male, somewhat attenuated and shining towards the a[)cx in the female; scrobes expanding posteriorly, antennal funicle 7-jointed.

Hab.- — Ea.'^terii, Middle and Western States. A careful comparison with Say's descrijjtion, supplemented by those of Gcrmar* and Bohemann,t leaves no doubt in my mind that this is Say's species. It varies considerably in size, Say's statement — "length more than one-tenth inch" — is too indefinite. The size as given by Germar — "magnitudive dellodk (/utti(la'" agrees, al- though the foot-note, " mihi invisa" makes it difficult to discover the source of his information unless based on Say's original description. C sabulirostris Sch. applies to the female ; it does not differ otherwise. This species may readily be distinguished from all the preceding species by the posterior tibise being sinjply subangidate and rather slender ; from all the following by the much stouter tarsi and on the whole larger size. The impressed abdomen of the male with its long- pubescence occurs in other species. A form occurring in Utah and Colorado differs considerably from the typical. Var. tenebrosm. — Dorsal channel of the ])rothorax reduced to a well defined and deeply impressed basal fovea, prothorax more strongly convex and very densely and finely punctured, the scaly vestiture is much finer and more sparse, scarcely at all mottled, giv- ing the whole insect a much darker appearance. This may possibly be C. /e/;ro,s«,s Boh., the descriptive phrase " thorace non canalicu- lata" being a])plicable to the variety under consideration, but the im])ression at the base of the prothorax is superficial. I have not been able to identify this species with any specimen before me. A specimen in the National Museum collection bcai's tlie cal)inct label, " C. lepro.nis,'' but the prothorax is distinctly canaliculate, the scaly vestiture a dirty ochreous. Why Bohemann should refer this spe- cies to Say as its author is difficult to understand, as I have been unable to discover any species described under that name in Say's writings. A. tarsaliM n. sp.

Agrees in all j»articulai-s with well authenticated specimens from various localities in Europe in my collections. This species has the third ventral segment less narrowed at the sides than in any other. The fifth ventral segment has a fovea-like im[)ression in both sexes. A specimen in my col- lection has the cruciform scutellar spot replaced by a sim})le basal spot as in Rhirwncus ; it does not differ otherwise. The lateral spots on the elytra are obsolete in some specimens. Group II. The few species constituting this group do not differ in general habitus from those of the first. The metasternum is not excavate for the reception of the apex of the beak ; the elytra are without obvious asperities. But two species belong here, which are distinguished as follows : Larger, metasternum with an acute, transverse ridge, scales unicolorons, white. iiasalis. Smaller, metasternum flattened, scales brownish, mottled with white. nebuIoi^iiM.

The mottling of the elytra is frequently indistinct ; when well marked this species more nearly resembles xuhfrncidttis, but differs abundantly by its much finer sculjjture and almost entire absence of elytral asperities. FKI.EXOSO.IIUS sen. uov. A peculiar species, unlike any other of the present subtribe known to me, forms the type of this genus.

Structurally, this genus is closely related to Auleatex, from which it is distinguished by the great irregularity of the prothorax, the tufts and crests of erect scales on tlie elytra and the dense scaly vestiture. It is represented by a single species. P. cristatiiN n. s]).

PI. xiv, figs. 34, 34rt, 34'>. — Very similar in appearance, less roliu-st. and a trifle smaller than the preceding species, and with which it also agrees in coloration and the scaly vestiture. It differs as follows: Prothorax fully one-fourth wider than long, sides straight and parallel in their basal half, feebly rounded in front, narrowly and not distinctly constricted at the apex, scarcely impressed before the middle, tubercles and apical cusps smaller, without tuberosity each side of the dorsal channel, the latter almost interrupted at the middle. Elytral interspaces equal, the cruciform scutellar spot differs in that the transverse bar is somewhat oblique ; a spot on the seventh interspace represents the oblique lateral line of the jjreceding species, another spot on the third inter- space near the apex; prosternum very deeply and less widely emarginate, sides of the emargination sti'aight, i)arallel, without ante-coxal ridges; pectus densely clothed with large white scales. Abdomen le.ss densely clothed with piliform scales. Legs as in zimmenminni, but more slender. Length 2.75 nmi. ; 0.11 inch. Hub. — Detroit, Mich., Illinois. Two female specimens, Mr. Dike's and my own collection. This species very closely resembles Perigaster obscurus in form and ar- rangement of the elytral .spots, but aside from the difference in the form of rostrum and the sci-obes has the anterior cusps of the pro- thorax less prominent and the last joint of the tarsi less elongate. The cruciform spot on the elytra is absent in Mr. Hike's specimen and rei)resented by the basal spot in the third interspace only. Group II. Phytobii veri. The genera and species comprising the Phytobii veri present an appearance peculiarly their own. The eyes are more or less promi- nent and not or only partially concealed in repose.

Eyes large, round, moderately convex, partially concealed in repose, with acutely elevated orbital margin ; prothorax strongly narrowed in front, ocular lobes obsolete, apical margin bicuspid, lateral tubercles present, basal margin nearly straight each side ; scutel very small. Elytra wider at the base than the prothorax, broadly oval ; pygidium nearly perpendicular ; pro- sternum rather short and deeply emarginate in front of the coxa?, not canaliculate, mesosternum short, feebly emarginate in front, truncate behind and forming less than one-half of the middle coxal cavities; motasternum long, entering well between the middle coxa3 ; second abdominal segment shorter than the two following segments together, the third nai-rowed on the sides ; anterior coxjc conical, prominent, rather widely separated, middle coxie small, globular, separated twice the distance of the anterior coxai and less than half the distance of the posterior. Legs slender, femora nnitic, scarcely •AMERICAN COLEOPTERA. 459 clavate, tibire very slender, not armed at the apex, tarsi with the third joint broadly bilobed, claws simple, divaricate. Thus defined this genus is readily distingujshed from Cidogaster by the stout and shorter beak, the oblique scrobes, obsolete post- ocular lobes and simple claws. From the following genus it is dis- tinguished by its short, robust form, the distinct prothoracic tuber- cles and the broadly bilobed third tarsal joint. From the rest of the genera of this subtribe, the present genus is separated by the shorter second abdominal segment and the third segment narrowed on tiie sides. The two species are distinguished thus : Larger, prothorax impressed at the base, elytra not conspicuously mottled. cretiira.

The elytra are more shining, not densely scaly and distinctly mottled with spots of white scales. M. scoliasus n. sp. — Oval elliptic, convex, black, antennsp and legs rufous, infuscate; above rather densely clothed with dirty gray scales, variable in size, underside clothed with small oval scales, not at all crowded except on the meso- sternum and the last ventral segment.

Beak stout, widened towards tlie apex, scrobes oblique, deep; an- tenna} with 7-jointed t'unicle, clava elliptic, acuminate. Kves large, rounded, more or less convex, witiiout distinct supra-(U'bital ridges; scutel not visible ; ])r()sternum long in front of the coxae, deeply emarginate, with distinct ante-coxal ridges ; mesosternum oblique, metasternum a little shorter than the first ventral segment ; second ventral segment as long, or longer than the two following segments together, the third segment not narrowed on the sides, fully attain- ing the lateral margin ; anterior coxie conical, i)rominent and rather widely separated, middle coxie globular, separated about tw'ice the distance of the anterior coxse, their cavities formed equally by the meso- and metasternum. Legs rather slender, third tarsal joint l)ilobed, claws armed with a long tooth. The species of this genus, although varying from a broadly oval to an elongate form, present a habitus peculiarly their own. The expression " without distinct orbital ridges," as used in the analytical table and again in the above description of the genus requires some explanation, inasmuch as such a ridge, ill-defined as it is, exists in most of the species examined by me. Dr. LeConte's statement, " no trace of supra-orbital ridge," is therefore erroneous. In the Euro- pean species, R. fopiarius, this ridge is quite prominent and the front concave, as much so as in certain Pelenomi ; it is entirely absent only in R. /oiuju/us Lee. and its European congener, R. perpeudicu- /((rls. In all the anterior coxiB are much more widely separated than in Pelenomn-^ or Mecopeltus. In all the species there exists a conspicuous scutellar spot of white or pale scales, and the anterior thoracic margin is entire. The ai)ical armature of the tibiiu in the male difiers in each of the three species. I have no additions to make to the three species heretofore known and which may be distinguished as follows : Eyes as widely sepaiated above as the width of the beak, the latter longer than the liead : form stout.

This species is known in our lists and collections as pericarpius, and it is not without hesitancy that I propose a new name for a fairly well-known species. In size and general appearance it agrees well with the European species, but difiers from it in the followijig points : 1. beak carinate ; this is constant, though varying in degree in all the numerous specimens before me, while in eight European speci- mens of pericarpius from different localities a slight indication of a carina exists only in two specimens ; 2. the curved imj)ression at the base of the rostrum is not noticeable in pericarpius ; 8. the fourth tarsal joint projecting about the length of the third joint, whereas in pericarpius the third is relatively shorter, the fourth })rojects distinctly more than the length of the former.

This genus is at once distinguished from the other genera of this subtribe by the very slender tarsi, the fourth joint equaling in length the three preceding joints. The rostrum is less stout, longer than the head, scrobes oblique, straight, at some distance from the eyes ; antennae with 6-jointed fuuicle, joints 1-3 elongate, club variable. Eyes rather small, round, convex and entirely exposed ; base of prothorax produced into an acute, triangular process at the middle ; scutel scarcely visible. Elytra wider at the base than the prothbrax, distinctly narrowed posteriorly ; pygidium large, prosternum very short in front of the coxve, broadly emarginate, without ante-coxal ridges, mesosternum broad, truncate behind, forming one-half of the middle coxal cavities, side pieces wide, ascending ; metasternum short, side pieces wide; first ventral segment a little longer than the second, segments 3-4 short, third not narrowed on the sides ; aiiterior coxie conical, prominent, subcontiguous, separated by a very thin lamina of the prosternum, middle coxse subglobose, rather widely separated, posterior cox^ small, distant from the lateral margin and but a little more widely separated than the middle coxae. Legs long and slender, femora mutic, tibiae not armed at the apex, tai'si as described above, claws simple. The two species thus far known to occur within our faunal limits present structural differences of sufficient importance to warrant the •establishment of two subgenera, as follows : Mesosternal side pieces wider, epimera ascending between the protliorax and the elytra, freely visible from above Phytobius. Mesosternal side pieces narrower, epimera not ascending between prothorax and tlie elytra, not visible from above Euhrj'-chiopsis. Subsenus Phytobius. Prothorax much wider than long, narrowed anteriorly ; mesos- ternal side pieces freely visible from above ; the derm is covered with a dense layer of scales, which, on the upper surface, overlap each other, forming a sort of water-proof covering .similar to that seen in certain genera of the Erirhinini.

Two males, one in Dr. Horn's (without Ibcality label), the other in Mr. Ulke's coll., are before me. Very closely related, if not identical with the European P. velaim, a male specimen of whicli, in Dr. Horn's collection, is .also before me, and from which it appears to differ only in the more elongate beak and the more slender an- tennae; the scaly vestiture on the upper surface also differs somewhat. I have retained the name of this species by which it is known in our collections and in the Third Supplement to the List of N. A. Cole- optera by Mr. Samuel Henshaw. As I had not seen any description^ of this species I wi'ote to Islv. E. A. Schwarz, the reputed author, for information, and to kindly give me the name, etc., of the publica- tion containing the description of this and two other species. This inquiry Mr. Schwarz has not seen fit to answer. I also wrote to several other gentlemen who might be in a position to give me the desired information, but with negative results. Under these circum- stances no other course is left for me but to describe the species as new. Subgenus Euhrychiop&is.
