THE DEVELOPMENT OF THE WINGS IN THE LEPIDOPTERA.

plates i-v.

By William Fairfield Mercer.

The development of the wings inside of the body of the larvae of insects with a complete metamorphosis is one of the most striking features in the transformations of insects ; it is, however, one that is not generally understood. Although the fact that caterpillars have wings was discovered by Malpighi (1687) and by Swammerdam (173*^)5 it is only in the last half of the present century that any exact information as to their method of development has been ob- tained ; and this information is only just finding its way into the general text-books.

The beginning of the solution of the problem was made by Weissmann('64 and '66) in his remarkable papers on the development of flies. These papers were followed by important contributions by Landois ('71), Ganin ('76), Dewitz ('81), Pancritius ('84), Schaffer ('89), Mayer ('96), Gonin ('92), and others. The most complete account that has yet appeared is that of Gonin.

Nearly two years ago, in the course of some studies of the develop- ment of the wings of Pieris, Professor Comstock came to the conclu- sion that in some respects the excellent account by Gonin was inac- curate. And at his suggestion I undertook the repetition of the tracing of the development of the wings in this insect. The follow- ing paper is the result of this investigation.

As Gonin's contribution appeared in a journal which is to be found in but few libraries in this country, it seems worth while to publish for American readers my complete results even though in many particu- lars they duplicate the results of Gonin.

It is with pleasure that I acknowledge the aid of Professor Corn- stock and his able corps of assistants ; without this and the resources of the entomological department of Cornell University, which were put at my disposal, this investigation would have been impossible.

The LiFE-His'i'ORV of F/rn's.

The observations on the number and duration of the stages of this insect were made on the July brood, which is one of the four broods of the year. The butterfly lays its eggs upon the food-plant of the caterpillar, sticking one at a time upon the leaves at varying dis- tances. The egg hatches in from four to five days. As the cater- pillar emerges, the head measures .36 mm. Excepting the first, the ratio of increase in head measurement at each moult is 1.55 ; in the case of the first moult it is slightly greater.

The caterpillar moults for the first time in from 30 to 48 hours after hatching. The head measures after this moult .6 mm. I'he cat- erpillar moults for the second time in from two to three days after the preceding moult, and the head measures .93 mm. In one day it moults again, and the head measures 1.44 mm. In one day more it moults again, and the head measures 2.22 mm. After four days it moults for the pupa, and seven days later the adult emerges. The butterflies pair when about 24 hours old, and the female at once be- gins to lay the eggs for a new brood. The whole life-cycle covers a period of about 22 days. The time of these changes varies some- what with the nourishment and the temperature. These points are summed up in the following table :

The caterpillar eats much and grows rapidly, and seemingly has nothing to do but to store up energy and fat to bring out the adult insect.

In moulting, the cuticle splits down the dorsal line of the first and second thoracic segments. During the latter part of the last larval stage the caterpillar ceases to eat and prepares to hang itself up for the pupal life. The approach of this event may be detected from the red color of the excrement, which is supposed to come from the cast- off cells of the epithelial wall of the alimentary canal. At the same time the caterpillar is searching about for a suitable place to hang itself up. It soon forms a button of silk to which it holds with its caudal prolegs and at once begins its girdle of silk over the thorax, fastening the ends to its support on either side of its body. The cat- erpillar is now shorter and changed in form somewhat as a preparation for i)upation, which will take place in about 24 hours.

Throughout this discussion the term prepupal period is applied to the time the caterpillar is hung up before pupation. This period is characterized by the fact that the wings are outside of the body wall although beneath the larval cuticle, the change in position taking place while the caterpillar is spinning the silken support for the pupa stage.

Technique.

The caterpillars were killed in hot water, small caterpillars being left in one-half minute, and large ones one minute.

Perenyi's fluid gave the best results as a fixing reagent. In fixing for wings the caterpillars were cut caudad of the third thoracic seg- ment, and also the head was removed before placing them in the fluid. The chitinous coat that covers insects is very hard to penetrate, there- fore to get a good fixation the greatest care is necessary. A large amount of the fluid in proportion to the caterpillars was used, the thoracic segments of from six to ten caterpillars being placed in from 30 cc. to 50 cc. of the fluid. The fluid was heated to 50° C, and the caterpillars transferred directly from the hot water and left from 8 to 12 hours in the fixing fluid. They w^ere then hardened in suc- cessive grades of alcohol as follows :

Absolute alcohol . . . . • 12 "

Absolute alcohol and cedar oil, equal parts, 12 hrs.

4 Journal New York Entomological Society. iv..i.viii.

Cedar oil, 24 hrs., or until the specimen was thoroughly cleared.

In the process of imbedding, the infiltration must be carefully done. To insure the best results, it is well to get the specimens into the hard paraffin and set them back into the oven for a few hours. This insures a uniform medium for cutting.

Sections cut from ten to fifteen microns thick gave the best results for the general outline, while for the finer cell structure sections seven microns thick were better. Sections were stained on the slide with hematoxylin and counter-stained with safranin to bring out the chitin. When staining with safranin it is necessary to leave the slides in for at least 24 hours, then differentiate very rapidly, dehydrate, clear, and mount all within a very few minutes. Orange (i. was also found to give good results as a counter-stain for chitin.

For the study of the wings as a whole it is necessary to dissect them from the body and mount in glycerine jelly ; the jelly must be cooled cjuickly in order to insure the trachea.' not being filled with it. To accomplish this, lay open the larva along the dorsal line and pin the cut edges of the tegument to the wax bottom of a dish, all being- done under water. The wings are recognized as small fiat l)odies a little longer than wide. Figure 12 shows a drawing made from a photograph taken and mounted as above. The dissection of the pupal wings to bring out the tracheae, for the study of the wings as a whole, is nicely brought about by placing the pupa in 4% formal for from six to ten hours ; this hardens the tissues and at the same time leaves the air in the trache;^, which appear as black lines under the micro- scope.

The First Larval Stace. (Plate I, Figs, i, 2, and 3.)

The wing-buds are found in the very earliest stages of the lar\al life ; embryos were not examined. Figure £ represents a section through the body-wall of one side of a thoracic segment at a point where a wing-bud is developing ; r represents the cuticle and // the subjacent layer of cells, the hypodermis. The section was taken from a larva which was not more than one-half hour old. At a point op- posite a trachea (Fig. i, /) the cells of the hypodermis are elongated ; these elongated cells constitute the rudiment of a wing or a wing-bud. Rudiments like this of organs that are not to be functional till the adult stage are often termed imaginal discs or imaginal buds. Near the center of the outer surface of this group of cells forming the

Mar. iy>D.] MeRCER : DEVELOPMENT OF WlNGS IN LePIDOPTERA. 5

iniaginal hud there is a slight depression beneath the cuticle (Fig.

As the larva advances in age during this stage (Figs. 2 and 3) the elongation of the cells is increased, the depression enlarged, until llnally the iniaginal bud (Fig. 3, i/)) is quite distinct and a thickening of the cuticle appears opposite a depression in the imaginal bud. This thickening began to show even in the early part of the stage. Near the trachea and the wing-bud there is in each case a group of cells which bear some resemblance to leucocytes and which were termed by A'erson embryonic cells (^cc); these are believed by Schiiffer ('89) to be a sort of lymphatic gland, a center in which leucocytes are develojied. From the study of these figures it is easily seen that the imaginal bud (//') in this stage is simply a thickening of the hypodermis.

The Sec(;)xd Larval Stage. (Plate I, Fig. 4.)

In passing from the first stage to this, the growth of the wing-bud has been gradual and not \ery extensive. The cells have elongated .somewhat and the small pit, referred to in the first stage, has in- creased to a definite invagination into which extends a chitinous plug (Fig. 4, /'j from the cuticle.

The Third Larval Stage. (Plate I, Figs. 5, 6, and 6a.)

After the second moult the cells of the wing-bud have increased in length, the invaginating process has been going on until the wing-bud is deeply sunken in the body cavity ; it remains, however, connected with the hypodermis by a thin membrane, the peripodal membrane ( Fig. 5, <?). The term peripodal membrane was proposed by Van Rees ('88) and was suggested by the fact that in the internal development of the legs of flies a similar membrane is formed ; as the leg-buds and the wing-buds closely agree in structure the terms applied to parts of the leg-buds are also applied to the wing-buds. Figure 6 represents a section at a point which shows the peripodal membrane {e) on both sides. The trachea has increased in size. 'Jlie plug of chitin at the opening of the invagination (Fig. 5, /' ) is readily noticed. To get a clear idea of the invagination it is necessary to study a series of sec- tions through it. A section through the center of the invagination will show the chitinous plug (Fig. 5, /') and the opening into the

in\agination. At a point two or three sections distant from the cen- ter, the invagination is closed in by the hypodermis of the body-wall (Fig. 6, /'). The opening of the invagination is, therefore, a narrow- pore.

The single layer of the hypodermis appears to pass into two or more layers in the wing-bud, *but upon a careful examination it will be seen that there is but one layer, the nuclei of the cells being at different levels, while the cell walls may be traced from one side of the wing-bud to the other. In this stage, at the point of nearest ap- proach of the trachea to the wing, there is a slight depression and the cells of the trachea are elongated slightly on the side toward the de- pression (Fig. G).

Different specimens of larwe in the third stage exhibit a great differ- ence in the appearance of the basement meml)rane of the hvpodermis of the body-wall. In some it is distinguished with difficulty, being merely a line limiting the inner ends of the hypodermal cells ; which, in this case, are the same diameter throughout their length. In others the inner ends of the hypodermal cells are prolonged into delicate fibers between which are spaces ; in this case the basement membrane con- necting the tips of their fibers is remote from the main body of the cell (Fig. 6(7, /-'///). In both cases the basement membrane of the wing- bud, which is directly continuous with that of the hypodermis of the body-wall, appears merely as a line bounding the ental surface of the bud. The tissue of the bud is solid, without the spaces represented in Figure 6c7. It is, therefore, difficult in some specimens to dis- tinguish the basement membrane of the wing-bud in this stage.

ThkFourtfi Larval Stage. (Plate I, Figs. 7-11 : Plate II, Fig. 15.) Sections of a larva taken in this stage (Figs. 7 and 8) show that the process of invagination has been going on at a rapid rate. The slight depression in the region of the trachea in the third stage (Fig. 6) has increased to a prominent evagination. It will be observed that in the course of this internal development of the wing there is first an invagination of the hypodermis, and later an evagination of a portion of this invagination. The evaginated portion is what is destined to become the wing ; while the remaining, thinner portion of the invagination forms the peripodal membrane.

It is in this stage that a temporary set of tracheoles is developed. The cells of the epithelium of the large trachea near the wing-bud

Mar. I900.J MeRCER : DEVELOPMENT OF WiNGS IN LEPIDQPTERA. T

(Fig. 7, T) are elongated on the side toward the evagination of the wing (Fig. 7, met). A little later in this stage these cells appear very much larger \vith large nuclei (Fig. 8, met). These cells are destined to form the tracheoles ; and may be termed the mother cells of the tracheoles. In some of these cells, very fine tubes are seen, through which the light passes in the section. This is the first ap- pearance of the temporary respiratory organs of the wing, or the tracheoles. Later in this stage the cells have wholly disappeared except the nuclei, and in their place are great bundles of capillary air tubes, the tracheoles, which difler from tracheae in lacking the spiral thickening of the intima (Fig. 15, //). The nuclei pf these mother- cells of the tracheoles do not disappear until after the development of the tracheoles (Figs. 10 and 11). It is evident from this that the tracheoles are not formed, as Landois supposed, from the nuclei of the cells, but from the body of the cells as described by Gonin. Figure 1 1 shows a group of cells in cross section, very much enlarged. In two of them the nucleus is cut through and appears, while in the other two the razor has not passed through the nucleus. In cut.ting across a group of cells containing a bundle of tubes, the section would show round holes, which is the case with these cells. Two other cells (Fig. 10) are shown in longi-section. These show the nuclei with a bundle of tubes surrounding them.

During this stage the tracheoles have no communication with the lumen of the large trachea about which they are developed. But as the new intima (Fig. 15, nin) is formed, which is to line this trachea in the next stage, it is not extended over the mouths of the tracheoles. It will be seen, therefore, that on the removal of the old intima (Fig. 15, oin:) af the following moult, the air in the lumen of the trachea will have free access to the mouths of the tracheoles (Fig. 15, mt) which now become functional.

Proliferation of the Traelieee.—.^i the very beginning of the fifth stage at the latest, and there is considerable evidence that in the latter part of the fourth stage, there begins the development of the permanent wing-trachese. These arise as a pocket-like evagination of the epithelial walls of the trachea that gives birth to the tracheoles. This is shown diagrammatically in Figure 9, ef. This evagination is increased in size, and others are formed, some of which branch andextend into the lumen of the wing, following in a general way the course of the bundles of tracheoles. Figure 9 is diagrammatic to show more clearly

8 Journal New York Entomological Society. [VoI.viii.

what is suggested in Figure 14, T. These evaginations are extended into the lumen of the wing, which process takes place while the tracheoles are becoming completed and straightened out. The lumen of these small tracheal in the wing, has no connection with the main lateral tracheal trunk (Fig. 9, //), since they are closed by the pre- existing intima, therefore these tracheae are not functional. As the tracheae lengthen the tracheoles straighten out and extend to the mar - gin of the wing. Tlie tracheoles occupy the space, the vein cavity, along the course of the tracheae as they push out into the wing. Ver- son thought that the tracheoles never reached the margin of the wing, but my observations bear out those of Gonin who says they do extend to the margin of the wing unless hindered by the more dense por- tion of the edge of the organ. It is probable that the pressure of the air is the main agent in straightening out the tracheoles.

The Fjkth Larval Stage. (Plate II, Figs. 12-14, 16, 17. Plate

III, Fig. 23.) In the study of this period two methods were used, that of direct observation of the entire wing-bud and that of the study of sections. The external lateral trachea sends out branches to the wing and these enter it at about one third of the distance from the hypodermal attachment to the margin and give the appearance, as Gonin states, of the stem of a nasturtion leaf (Fig. 12). The tracheae seem to enter as into an arm pit and the tracheoles extend from this point to all parts of the organ, even to near the margin where the cells are denser and do not allow them to penetrate. The tracheoles extend in masses of bundles from the trachea as previously described. Tracheae, be- ing filled with lymph at this stage, are not easily seen in the entire wing-bud, but the photograph for Figure 12 was taken under very favorable conditions and they are faintly outlined.

Upon the study of sections (Fig. 14) it will be observed that the process of evagination has gone on from that described in the stage preceding this until the v^'ing is nearly surrounded by the peripodal membrane (e). The evaginated portion is better shown in Figure 16 which is a frontal section of the larva and gives a longi-section of a part of the wing. In cutting the section shown in Figure 14 five layers of hypodermal origin were passed through, viz., the outside body wall or hypodermis (Ji), the external part of the peripodal mem- brane (if'), the external boundary of the wing-bud (//), the internal

Mar. ijoo.] Mercer : Development of Wings in Lepidoptera. 9

boundary of the wing-bud (■<('), and the internal wall of the perii)odal membrane (<').

T/ie Parts of tlic Wiui^. — These can be best studied from the sec- tions of the wings in various planes. Figure 13 shows a cross section of a wing through a vein cavity ( /r'). This vein cavity contains a trachea (/) which is not functional, is filled with lymph, and contains no chitinous intima. This trachea consists of a single layer of epi- thelial cells which will finally change somewhat upon their internal margin and form the chitinous intima in a manner to be described later. In this vein cavity sections of tracheoles, both cross and lon- gitudinal, are found; those in cross section appear as holes through a mother-cell (//). Leucocytes (/) are also found.

In a frontal section (Fig. 16) the lateral trachea ( Z") is cut in longi-section, and the razor has passed through a wing trachea (/) in longi-section. This trachea has passed into the lumen of the wing (/7t'). The tracheoles (//) are connected with the lumen of the main trachea at a point (w/) while at the same time the chitinous intima (///) extends across the mouth of the trachea (/') which, as yet, has no chitinous intima and is not functional.

Figure 17 is a section of a wing in a slightly different plane than Figure 14 ; enough so that a mass of tracheoles (/"/) appears instead of the bases of the developing tracheae (Fig. 14, T).

iJuring this stage the wing has been growing very rapidly and the ventral margin has extended toward the feet, and at the latter part of the period the wing changes from the inside of the body to the out- side. This is all brought about while the caterpillar is searching for a suitable place to hang itself up.

The basement membrane (/v//) is not easily distinguished in some sections in this period though quite distinct in others ; it is shown in Figures 16 and 23. In many places between the vein cavities in the wing the two layers of the basement membrane appear as coming to- gether and are somewhat fused. In some sections (Fig. 13) the line of union is seen with difficulty, but even in this section the line of contact is faintly made out by careful focusing. The union of these two layers forms the so-called middle membrane (Fig. 23, bin) which will be discussed more fully later.

The Cuticle of the \\'ixg-Bud. There has been a long dispute as to whether or not a cuticle is formed around the wing-bud in the younger stages.

10 Journal New York Entomological Society. ;v„i. viii.

Pancritius thinks it is and figures it as a thick layer of chitin with the same structure as the outside cuticle of the body. Gonin thinks it is not formed at all until the latter part of the last larval stage. In Sanniuoidea exitiosa (Fig. 20, /V) there is no doubt of a definite layer of cuticle surrounding the wing. In Aiitomeris io there is a much more definite layer of cuticle ; this is true in an early stage, even be- fore the proliferation of the tracheae (Fig. 21, r). The tracheoles alone are functioning at this period. The thick hard cuticle in this specimen may be traced quite a distance into the invagination ; and it will be noticed that it gradually thins and finally l^ecomes very thin and delicate. Iri Pieris the layer of cuticle extends in the form of a plug as described in the discussion of the first period, and the wing- bud is not surrounded by a chitinous layer until the fifth stage when a very thin, delicate, structureless membrane of cuticular nature appears which is destined to become the cuticle of the wing of the pui)a.

The Ori(;ix of ihe Cuticle. My observations indicate that the cuticle is a product of a trans- formation of the outer ends of the hypodermal cells instead of a secre- tion thrown out from these cells. By the use of chitin stains, the chitinous nature of the ends of the cells in the pu|:)a wings (Fig. 35, c~) is brought out. As more evidence that it is not a secretion, the cuticle in the development of the prepupal wing (Fig. 28, pc) is seen to gradually decrease in density as it approaches the hypodermal cells and gradually fades into the cells themselves. These facts have been observed many times and in many places upon the insect other than upon the wings, during the course of this investigation.

Several observers have noted that the cuticle is often divided into polygonal areas corresponding to the subadjacent hypodermal cells. It is not probable that this would be the case if the cuticle were a se- cretion thrown out from the cells ; for in such a case the products of the different cells would naturally merge into a continuous layer. But the formation of a cuticle by a transformation of the outer por- tions of the body of the cells would result in the formation of such areas.

Ordinarily this division of the cuticle into areas is not \ery evident in sections. But in the case of one larva of Sanniuoidea exitiosa the areas were remarkably distinct : so much so that the sections of the cuticle broke up into little blocks corresponding to the hypodermal cells (Fig. 37).

The Preplpal Period. (Plate III, Figs. 22-25; 27-28. Plate

IV, Fig. 29.) In all the previous stages of the caterpillar the wings are inside of the body cavity. In this stage they are found upon the outside. I one dissects the wings out in this stage, he finds it necessary to dissect away the body wall before he can get to the wings if he works from the inside as he did in the other stages. But if he takes the expenevice of Swammerdam and plunges the caterpillar into hot water a te^^ times, then carefully takes off the chitinous covering, he will find the wings as external appendages the same as the legs.

For some time before the last moult, that is betore the larva hangs itself up for the pupal period, the wings are transparent m the body, and their position is recognized only by their accompanying trachea. As the wing becomes gradually opaque it also becomes very much smaller and the contour is irregular and folded. The wings have now disappeared from the interior of the body, but are easily found in their new position by the method given above.

This change in position takes place in a very short time whde the caterpillar is searching for a place to hang itself up and spinning he button of silk to which it attaches itself. This is a very curious phenomenon, and one that needs explanation Ceroid explains U easily ' ' The germs of the wing ' ' he says ' ' although hidden under the skin have a great tendency to come to the outside." Landois^ who considered the wings as appendages of the tracheal trunk instead If an invagination of the hypodermis, thought that these germ opened away through the muscular bed with their points and tha then tl.e hypodermis withdrew, thereby letting it appear under the form of an evagination of the integument. Weissmann and others have advanced the idea of the breaking down of the l^YPoderm^ o allow the wings to reach the outside. Dewitz does not refer to the taking down of the hypodermis. According to him the o^^ning of the cavity of the invagination is enlarged just enough to gn a free removal of the wing and it remains for some time like a picture n a f ame. Soon the wing becomes free and the hypodermal frame becomes a part of the body wall. Goi^n says, " This theory raise two principal objections. First, it is difficult or ^^^ ^rific of the neripodal cavity to be able in a few hours to enlarge itself without a ea or ent ; in the second place, in order that all of the envelope coiild find a, place upon the thorax it would be necessary that the

12 Journal New York Entomological Society. [Voi. viii.

circumference of it should be much increased. Now this is not the case. The second and third segments are swollen only while they contain the germs of the wings. After these organs issue the diam- eter does not exceed that of the neighboring segments." Gonin ex- plains the transition of the wings according to the theory of the destruction of the envelope. As evidence of this he cites the fact of there being a large amount of debris around the wing and between the two layers of the integument. He also refers to the fact of hav- ing a series of slides in which the front wing is entirely exterior while the hind wing has not completed the transformation.

I have observed all this, but I believe that this structureless sub- stance referred to by flonin is none other than the moulting fluid. The reagents act upon this substance, coagulating it, which gives it the appearance of degenerating tissue. Stains act upon this substance very vigorously, even more so than upon the hypodermis. But since I find this structure around the entire larva (Fig. 29, ;///) as well as around the wing, in about equal (quantities, I believe it has no con- nection with broken down tissue.

A careful study of Figures 18, 19, and 20 which were taken from the peach-tree borer, Figure 18, from a caterpillar just before spin- ning its cocoon. Figure 19, from one which had begun to spin its cocoon, and Figure 20, from one which had just completed its cocoon, will show the method of the transition of the wing from the inside of the body cavity to the outside. It is found that the dorsal part of the wing (c/ ) emerges first. Figure 18, .v shows the two layers of the hypodermis, the one the external hypodermis and the other the peripodal membrane, drawn back a little but not fused as shown in Figure 19, .v. The fusion of the two layers and the draw- ing dorsad in the direction of the arrow in the latter case is very evi- dent. In the stage shown in Figure 20 the dorsal fold at .v has entirely straightened out. During this time the wing has grown con- siderably as shown by the relative size of the figures. Figures 19 and 20 both being drawn to the same scale. The same result is shown by the ventral fold v. In the stage represented by the first two figures the walls have not fused, while it is easily seen that they are coming closer together in the course of the development. In the third case, represented in Figure 20, the walls have fused at v and drawn ven- trally in the direction of the outside arrow. During the course of the development the wings now grow very rapidly in the direction of the

Mar. I90C.] MeRCER : DEVELOPMENT OF WiNGS IN LePIDOPTERA. 13

feet. From the very nature of this growth and the extent of it the peripodal membrane on the internal ventral side is swung dorsad in the direction of the inside arrow. Finally the ventral fold has straightened out as the dorsal fold did and the hypodermis has assumed the position shown in Figure 29, j'. The wing is now on the outside of the body. The fused portion of the hypodermal wall is broken down and disappears with the development of the adult hypodermis. The ventral hypodermis approaches the dorsal hypo- dermis as the larva increases in age until there is only a narrow open- ing into the lumen of the wing (Fig. 29, ho) which corresponds more nearly to the lumen of the adult wing.

Gonin's objection to the idea of Landois, who thought the folds entirely straightened out thereby placing the wing on the outside of the body-wall, is not sustained. Gonin observes correctly that the thorax is not larger after the transition than it was before. Accord- ing to my observations given above there would be no necessity for the enlargement referred to, for what slack there is is needed to form the ventral wall (Fig. 29, _r) after the transformation has taken place. It will be seen also from the above description that the part of the fold that disappears is a small portion of the peripodal membrane and a piece of the hypodermal wall.

During the time of the last larval stage and especially during the latter part of it (prepupal period) the wings have been growing veiy rapidly. Now after the Avings are on the exterior of the body this growth is even more rapid. The wings have reached the region of the feet and yet the growth is increasing. In order to allow this growth and still have the wings confined in the limits of the segments of their origin they become folded and wrinkled, so that the surface appears convoluted (Fig. 28). During this stage the wings become free and conspicuous in the section. A thin layer of cuticle is laid down upon the surface and follows the contour of the wings (Fig. 28, pc). This cuticle is thicker on the portions of the wing that will come to the air upon pupation, at the same time it must be very different in texture from the outside cuticle of the body for upon pupation it nmst needs straighten out as the wing expands.

On studying the wing-buds as a whole the trachea can be seen, not because they are filled with air but on account of their chitinous intima (Fig. 22, T). Tracheoles (//) are shown in the wing with their point of attachment in the axis of the wing. At the time the

1^ Journal New York Entomological Society. [voi.viii.

caterpillar spins up, the tracheae show very flilntly but as the age in- creases they appear more prominent and the intima is very evident. During the early part and the middle of the last larval stage the tra- cheoles (Fig. 12, // ) are in great abundance, but in the prepupal stage they have begun to decrease in number and extent (Fig. 22, // ). As the caterpillar moults for the pupa the intima of the main trachea (Fig. 16, ///) is pulled out which opens the mouths of the wing trachere and allows air to enter ; and the trachea; thus become func- tional. It is a question as to what now becomes of the tracheoles. Gonin says' that they are drawn out at the time of this moult. He al- so says that this can be easily demonstrated. But the results of my observations are very different, as will appear later.

The Pupal Wim(;s. (Plate III, Figs. 24 and 26. Plate IV, ex- cept Fig. 29 and Plate V. )

During the pupal stage several important changes take place in the structure of the wing : the temporary or larval tracheoles disappear ; a secondary or pupal system of tracheoles arises : important changes take place in the trachea; ; and a complicated series of changes takes place in the form of the hypodermal cells and of the l)asement mem- brane.

The Disappearance of f/ie Temporary Tracheoles. — The temporary tracheoles are found in pupal wings (Fig. 26, //) but not in such great numbers as in larval wings. They run in straight lines much the same as in the larval wings, but they are found oi)ly in the axial region of the wing, and that only in very young pupa;. They are at- tached to the epithelial wall of the trachea (Fig. 2)2,^ ^H- '^'his evi- dence will add to the proof of the theory of Landois and Pancritius who thought that the tracheoles of the larva disappeared by absorption in the pupa, and disapproves the statement of Gonin referred to above.

The Deve/opinenf of the Secondary or Pupal Tracheoles. — A new system of tracheoles now arises from the trachea;. This may be called the secondary system of tracheoles. The two systems are en- tirely different and have no relation the one to the other. The tem- porary or larval system has its origin from the main tracheal trunk or from the bases of the Aving trachea, while the pupal system has its origin from the trachea; in the wing itself and functions during the pupal life. The secondary system extends at right angles to the trachea; and ])enetrates the wing substance (Fig. 24, //) while the

Mar. I900.] MerCER : DEVELOPMENT OF WinQS IN LfPIDOPTERA. 15

temporary system extends in straight lines from the axial region and follows the course of the tracheae TFig- 26. //) practically parallel with them and functions only during the larval life.

The C/nvii^i's in tlie Structure of the Trachecc. — In the very young pupa the tracheae (Fig. 30, /) retain the characteristics of the tracheae of the ])receding stage except that the cells of the epithelial layer are not so distinct. This indistinctness increases with the age of the pupa until in the old pupa (Fig. 35, T) the walls between the cells have disappeared. At this time the epithelium appears under low powers to be thrown into folds ; under high powers its degeneration is revealed. The nuclei are still (piite distinct ; but the cell body is becoming semi-transparent except in a branched central area where the i)rotoplasm is of greater relative density. In this stage of the de- generation of the trachea the intima appears as a thin membranous structure in the lumen. Sometimes it appears merely as a line, at other times as a loop in a great variety of forms (PI. ^', P'ig. 38, ///).

In a later stage the inner boundary of the cells is broken down and the cell l)ody is evidently disappearing. The central branched part of the cell body is the last to go (PI. V, Fig. 39) and projects for a time into the lumen of the trachea.

A degenerating trachea in this stage is figured by Schiiffer (his figure 37) and described as Semper's Fliigelrippen (p. 646). He re- gards the branched remains of the cell body described above as tree- like processes of an intima, and the remains of the intima he believes to be a secretioai from the walls of the tube.

Semper's original description of the so-called wing-ribs ('57, Taf. XV, Fig. 6) was evidently based on an examination of a trachea which had just begun to degenerate. The intima had separated from the ei)ithelium and was mistaken for a central nerve, but the epithelial cells were still distinct and of the usual form.

This mistake of Semper has found its way into a large part of the literature on this subject and has been the cause of much confusion.

It is evident that this degeneration of the wing tracheae finally be- comes complete ; for in the wing-veins of the adult the trachea; are lacking.

The Ch(i/i}(es in the Hypoderniis and tlie Basement Alcmbrane. — Our knowledge of the changes that take place in the course of the develop- ment of a wing has been greatly confused by what are evidently mis- conceptions regarding the nature of the membrane limiting the inner

ends of the hyi^odermal cells. This membrane is easily seen in the early larval stages to be continuous with the basement membrane of the hypodermis of the body wall and is obviously a homologous struc- ture. In the fourth larval stage, tlie upper and lower hypodermal lay- ers of the bud come together and the two opposed basement mem- branes appear as a single membrane : this has been termed the middle moiihraih- of the larval wings, and its homology with the two base- ment membranes of the u])])er and the lower hypodermal layers of the wing overlooked. At the end of the fifth larval stage just before the evagination of the wings, which is characteristic of the prepupal period, the wing-buds become transparent so that they are seen in dis- section with difficulty ; tFieir position, as already indicated, is rec- ognizable only by the accompanying trachCcV. In sections of the wing-buds made at this time, the so-called middle membrane is seen only with difficulty. This has given rise to the belief that it disap- pears at this time. Later when the wings become more opacpie, /. c, in the pupa stage, the two basement membranes are again easily seen. Semper ('57 ) believed that the reappearing basement membrane was a new structure, which he named the,v;v///r//;/f7;//v(?// ; and he describes its formation from mesenchymatous cells that had wandered into the wing. The result has been that students of the subject have been confused by descriptions of three different structures, the Ijasement membrane of the hypodermis, the middle membrane of the larval wing-buds, and the grundmemljran of the pupal wing ; when in real- ity there is only a single structure, the basement membrane.

The Developmeuf of the Venatuui of the Jl7//xs- — As stated above, during the fourth larval stage, the upper and lower hypodermal layers of the wing-bud come together, and the two opposed basement mem- branes appear as a single membrane, the so-called middle membrane. This union of the two layers of the wing does not take place, how- ever, throughout the entire extent of the bud. Along certain lines, spaces occupied by tracheoles and lymph remain. These are thefore- runfiers of vein cavities, and into these the tracheix; extend during the fifth stage (Fig. 12). In the fifth stage, therefore, the \'enation of the wing is outlined, each vein consisting of a cavity filled with lymph and containing a trachea. It is not, however, till the pupa stage that the wing-veins in the same sense in which the term is used by Ento- mologists (/. e., the cuticular framework of the wing) are developed. These so-called wing-veins are merely thickened lines of the cuticle bounding the pre-existing vein-cavities.

^r,•u■. .900.] Mercer: Development of Wings in Lepidop.era. it

In some cases the formation of a distinct vein-cavity follows .the development of the trachea within. This is shown in the section represented in Figure 14. Here there is one large vein-cavity con- taining a trachea ; but the other tracheae are closely surrounded by the hypodermal tissue of the wing. It is probable that this surrounding tissue is forced away later by blood pressure thus forming the large vein cavities characteristic of later stages.

T/ie Formation of (he Hypodermal Pillars. — During the prepupal period, that is between the time at which the wings pass out from the body cavity and the time of moulting the last larval skin, there is a great increase in size of tTie wings. This e.xpansion is doubtless brought about by blood pressure. If there were no provision to prevent it, the forcing of the blood into the lumen of the wing would distend it like a filled bag. But the upper and lower sides of the wing are tied together by fibers of hypodermal origin, which have been termed the hypodermal pillars. The result is that the expand- ing of the wing is in a single plane.

According to the ol)servations of Mayer ('96) the formation of these hypodermal pillars takes place in a complicated manner: but I have not been able to confirm his observations. In Pieris it takes place as follows :

During the period in which the two basement membranes are closely applied to each other, thus forming the so-called middle mem- brane, these membranes fuse in places, thus uniting hypodermal cells of the opposite sides of the wing. Later, at these points of fusion tie fused basement membranes disintegrate, or at least are not to be distinguished from the bodies of the united cells, which form a fiber passing from one cuticle to the other.

When the wing is expanded, the hypodermal cells, each of which must cover a much larger area of the surface of the wing, are greatly shortened ; and thus the two basement membranes are pulled apart ex- cept in those places where they have fused. Thus is presented the appearance shown in Figure 12, Is, which represents a section of a vein cavity and several spaces l)etween hypodermal pillars.

Later in the pupal stage, the hypodermal pillars appear to contract, for the two surfaces of the wing are brought even closer together (Figs. 31 and 35). In fact, in sections of wings of the adult very little hypodermal tissue can be found ; and in many places the two cuticular layers are closely applied. The details of the disappearance of the hypodermal pillars have not been worked out.

Urophora intcmif'fa Macquait is a synonym of Rivellia hoscii, and Orlalis bipars Walker, of Rivellia viridulans. Loew was correct in placing Ortalis ofrccda Walker as a synonym of the last named species, with which the description fully agrees, while it does not at all agree with Cluvlopsis cenea, to which Osten Sacken assigned it from an ex- amination of the supposed types.

Tcphroiiota hiniiilis Loew is a synonym of Trypeta narytia \\'alker. The fact that Walker attached the label to a specimen of Clurfopsis (Enca, as observed by Osten Sacken, is sim])ly another instance of that author's well-known carelessness; his description oi iia>ytia agrees per- fectly with liii/iiilis, while it is not at all applicable to icfiea.

Our s[)ecies of Ccfoxys should be placed under Melieria of Des- voidy (Essai Myod., p. 715; 1830). The name of Ccfoxys, which dates from the year 1835, could be used for the European species placed by Schiner under Mrckclia, the latter name being preoccupied.

ON THE LARViE OF ATOMACERA AND SOME OTHER SAW-FLIES.

B\ Harrison (r. Dvar.

Atomacera* desmodii, sp. nov.

Male agrees with Say's description of A. i/c/'///s, but is smaller, length 2 mm. or less. Four submarginal cells are present : the third joint of antenna; does not taper to tip, but is somewhat thickened on its basal fourth.

Female agrees with Norton's description of .4. nificollis, but the thorax above is wholly yellow red, without any black s])ot and the third joint of antenna is more thickened. Length 4 mm. Closely allied to A. nificollis Xort., but the third submarginal cell has its bor- dering veins parallel, while in nificollis they are divergent. Larva, last three stages observed.

Stage. — Head .6 mm. As in the next, translucent yellow, the tood green, shining ; spinous tubes black walled.

Pcniiltimafc sArgt'. — Head .<S mm., pale brown, eyes black. Body as in the last stage, but more yellowish, yellow except for the green food, the tubercles only very faintly shaded ; nothing conspicuous but the black-walled tubes in twelve transverse rows which make the larva look shortly spiny. Thoracic feet stumpy, thorax a little widened.

Zast s/tig('. — Head round, brownish green, shining, ocellus in a black spot ; antenna; rudimentary ; width i mm. Body somewhat flattened, the subventral region protruding, fluted ; feet on joints 6 to 12 and 13, rather slender. Segments with four rounded areas on each side like short tubes on the posterior third of the segment, subdorsal, lateral, stigmatal (posterior) and subventral. These tubes are hollow, colorless, dusky edged, erect, and from the top of each a round drop exudes when the larva is irritated. Before the subdorsal tube on an- nulet I is a tubercle with a seta; another on annulet 2, also before the tube, consisting of two tubercles conjoined or separate; below the subdorsal tube and touching it a large tubercle with one seta ; the stigmatal tube arises from the upper edge of a large tubercle with one

seta ; the subventral tube from a large tubercle forming the projection of the subventral ridge on which are several seta^ ; foot with small seta^. All the tubercles are shaded with dusky black except in their centers. Segments obscurely 2-annulate, the annulets minutely gran- ular in the center. Body otherwise green, shining, smooth. The glandular tubes form a row on the anterior edge of the cervical shield and on joint 13, fringing the body; the anal plate is smooth.

Cocoon. — Loose, irregular, of yellowish brown somewhat reticular silk. Xo ultimate stage, the glandular tubes becoming shrunken on spinning.

Food-plant. — Desmodium. Found by Mr. A. Busck and the writer in Alexandria Co., Virginia. Chain Bridge, ^'a. (Busck); Rosslyn, Va. (Dyar). Atomacera ruficollis Norton.

No males have been bred, but they will probably prove to be A. debilis Say when obtained, as originally suggested by ^^'alsh.

The following notes are taken from the books of the Department of Agriculture (no. 3198) and were written by A. Koebele.

"August 24, 1883, found a small saw-fly larva on TT/yVjv/^v- mos- cheutos L., sometimes two or three on one leaf. They are about 10 to 12 mm. in length, of a light green color on the upper side and almost white on the under side ; head black ; a transverse row of short black spines on each segment, longest in front ; stigmata black. There is also a variety where the spines are not l)lack, but evidently the same insect. Spun a (quadrangular cocoon."

In the preserved alcoholic material the head is round, prominent, brown black, a space in clypeus and mouth whitish; width i.i mm. Antennas rudimentary, not joined. Body with segmentary rows of stout, rather long, black tubes, somewhat longer on the thorax. These are longer than in A. desniodii. Anal plate rectangular, dark brown except at tip. Thoracic feet large, the thorax a little enlarged laterally ; abdomen smaller, somewhat flattened, its feet small, on joints 6 to 12 and 13. Feet all pale. There are a few minute set^e which can hardly be deciphered in the specimens ; probably they are as in A. desmodii. In the pale variety mentioned above, the head is brown over the vertex, a (juadrangular patch in clypeus and eye black. Body tubes colorless. Both species of Atomacera rest flat on the venter like slugs, eating the parenchyma of the leaf from below. They are slightly gregarious.

Priophorus irregularis, sp. no\ .

Male. Length 4.5 mm.; antenn?e long and slender, third joint shorter than fourth, finely pilose, joints 3 to 5 a little expanded at the apices. Face on each side of the ocelli channeled; a flat ridge pass- ing down between antennie ; claws with a tooth at middle. Shining black, ])alpi, knees and tibia; whitish except the tip of the middle and hinder tibix^ ; first joint of tarsi whitish at base, the rest black. Wings hyaline at tip, the basal three-fourths smoky black. Outer cross nervure of lower under wing cell received at middle of upper cell. One male. "\\"eirs, New Hani^jshire.

Possibly this is P. (vqiialis Nort. (just as P. soliiaris Dyar may be P. sinipliiiconiis Nort.) but my specimen does not coincide well with the description.

Lar\\x% last two stages observed.

PeiiiiHii)iafc stiv^e. — Head wider than high, mouth projecting, shin- ing black with a few hairs ; width i mm. Body of uniform width, rather wider than high, slightly smaller at both extremities ; a large, con- spicuous, black anal plate. The two rows of low, obscure but rather large watery tubercles bear evident stiff, recurved simple white hairs long on the posterior row, short on the anterior one. P^ody not dis- tinctly annulated. i)ale honey yellow, shading into orange on joints 2-3 and 12-13. -^ J'O"' of large, rounded, segmental, subdorsal l)lack spots and a similar smaller subventral row. Abdominal feet on joints 6 to II and 13, the feet slightly spreading, not conspicuous from above, pale or blackish tinted.

Last s/ai^r. — Head black ; width 1.2 mm. Body rather flat, with manv white hairs from irregular warts in two transverse rows. An- terior row of hairs moderate, posterior larger and from larger tubercles. The segments are 3 -annulate but the anterior annulet bears very few or no hairs. Body whitish, joints 2-3 and 11-12 orange yellow. A row of large black subdorsal spots on joints 2 to 12 over the front row of hairs ; anal ])late black, large. ^\'arts colorless, transparent. Rarely there are traces of small black dots subventrally. Tracheal line white ; feet colorless : hairs all white, recurved. Later the sub- dorsal dots become very large, the subventral ones distinct or absent, white fat granules appear dorsally except at the vessel. The spots may extend from joints 3 to 13.

Found on smooth willow at Woods Holl, Mass., and Weirs, N. H.; in the latter place there were hundreds of larvae on one bush which

they had defoh'ated. Usually only a few on a bush, sitting flat on the venter on the under side of the leaf. The cocoon is spun between leaves. No ultimate stage.

Larva referred to as "N," Can. Ent., XXVII, 340.

FHeronus ostryae Marlatt.

What I consider to be this species occurred to me on Carpiiius Virginiana in Maryland, but it was not bred. The name has probably been given after the wrong tree.

Stage I. — Eating a hole in the middle of the leaf, the body curled in S-shape. Head smoky testaceous, a dark lateral shade, eye black, shining; width .4 mm. Body translucent whitish, finely annulate, shining, food green ; anal segment swollen ; feet on joints 6 to 1 1 and 13, not used.

Stage II. — Head whitish, slightly testaceous, eye black with a shade behind ; width .7 mm. Body colorless, the food green, finelv annulate; joint 13 enlarged; feet on joints 6 to 11 small ; antenna a rudimentary point.

Stage III. — Head rounded, greenish, shining, a black shade on each side and an elongate one on the vertex ; width i mm. Body translucent green, the segments about 6 annulate ; thoracic feet clear with black marks at the bases ; abdominal feet short ; joint 13 swollen, with a pair of thick, swollen-tipped clear anal prongs. Neither tra- cheal line nor dorsal vessel contrasted.

Stage IV. — Head pale brownish green, a black shade behind the ocellus and a linear one on the vertex posteriorly ; with 1.3 mm. Seg- ments rather obscurely 6-annulate, translucent green, dorsal vessel not showing at all, tracheal line fine. Feet on joints 6 to 11 distinct, small, joints 12-13 a little enlarged, the bulbous prongs brown at tip. Thor- acic feet clear, testaceous at base.

Stage V. has been briefly described Journ. N. Y. Ext. Soc. V, 26.

Harpiphorus tarsatus Say.

A local form of this species occurs on Long Island, N. Y., in which the larvae differ from the form that I have previously described in pos- sessing the white pruinose coating. This is, doubtless, the true tar- satus, as the flies have the hinder tibiae entirely black as described and not more or less pale on the basal portion as in those bred from the non-pruinose larva.

Harpiphorus testaceous Xorton.

There is a published note (Insect Life I, 345) stating that the larva of this species was found on Polygonum and Vitis. However, on consulting the note books of the Department of Agriculture, I find that the \zx\x. refused these plants and it is pretty evident that they had been wandering after having defoliated their bush of Cornus. These particular larvte were not bred, but others, stated in the notes to be "identical" were bred, and, though labelled /(^j/d-rif^tfi- corre- spond with my specimens of varianits. Some preserved larvae bear- ing the same number (Dept. Agri., 3543) are also true varianiis. The true testaceous seems not to have been bred as yet.

Thoracic feet short, distinct and spreading, marked with black, visible distinctly from the lower side of the mine. Body colorless or faintly yellowish, the food in alimentary canal green ; two dark spots on venter of thorax. Segments 3-annulate, with small blackish tul^ercles on each annulet ; one on the first, four on the second reaching to the black spiracle, three on the third and a few on the subventral folds. Abdominal feet very small and short on joints 6 to II with also slight lumps that resemble feet on joints 12 and 13 anteriorly. Anal plate transverse, dusky black.

PRELIMINARY NOTES ON THE LARV^ OF THE GENUS ARCTIA.

By Harrison G. Dyar.*

I think it would be very appropriate if the members of this society should attempt to find out what is still unknown about the life histories of our species oi Arctia or Euprcpia, as the genus is now called. It is a specially interesting one as we have a number of closely allied forms, the exact limits of which are still imperfectly known. The larvae resemble each other closely, yet present some well marked points of difference. As the species are all rather common and so many of them live in our usual collecting grounds, it ought to be comparatively easy to find them and work the matter up. As a prelim- inary to this w'ork, I will briefly review for you how our knowledge of these larvfe stands at present. You will be able thus to avoid du- plication of work, and also to correct the previous work, where it has been erroneous. As some of you may receive eggs of larvae from cor- respondents in different states, I will review all the matter that is ac- cessible concerning the North American species. Some of this, gathered from the material in the National Museum and the notes of the Department of Agriculture, has not been published.

I. Virgo as moth is a distinct and well marked species. Superfi- cially, smaller specimens resemble iutcrmcdia or partJicnicc, but are always distinguished by the broad lining of the median vein and the two discal spots of secondaries. MicJiabo is the nearest ally, but these species have a different facies and are not likely to get mixed together. Virgo is abundant, particularly northward, and is a striking species, readily attracting attention ; yet our knowledge of the larva is incom- plete. The mature larva is black, abdominal feet and subventral warts reddish ; hair bristly, black, reddish subventrally and at the an- terior end ; no markings on the skin. The larvae hibernate nearly full grown, apparently in the penultimate stage or in the one before that, width of head 2.4 or 3 mm. I think there is only one annual generation and the hibernating larvae feed up in the Spring to emerge as moths in late July and early August. A number of descriptions of this larva are extant, but are brief and do not cover all the stages. Abbot's figure is much too pale and Stretch describes the larva as hav- ing a narrow flesh-colored dorsal line. It remains to be determined whether the larva ever really varies to this extent, and the full life history, including all the larval stages, should be described. The char- acterization that I give of the larva is taken from the specimens in the National Museum (Dept. Agr. no. 2484) and from some living specimens received from Mr. Doll in the late Fall of 1893.

36 Journal New Yokk Entomological Society. [Voi. viii.

2. VirginiLiila is also a neatly distinct species not likely to be con- fused with anything. The absence of the transverse lines and the yellow secondaries give it a very characteristiq look. About the larva very little is known. The moth flies early ; I have not taken any after the middle of June and I presume the larva must hibernate full grown. I have not had the larva, nor has it been bred at the Depart- ment of Agriculture. A brief description has been published by Mr. Coquillet, but I cannot gather from the description anything that will distinguish the larva from that of virgo. Practically everything is still to be learned about this species.

3. Miiliabo is a peculiar form, in markings close to virgo, but in color so near argc that the two are liable to be confused, and have been so in some collections. It is a simpler form than arge, the bands retaining their usual shape, only the inner one being occasionally somewhat tooth-like. The species ranges throughout the Atlantic States like the preceding, but it is commoner southward. I have no dates of flight, except one record of emergence of a moth from Florida on April 15th. The larva doubtless hibernates full grown. No description is extant ; but fortunately I have a blown larva before me from the Riley collection as well as cast skins from the Department of Agriculture and some notes (Dept. Agr. no. 2588). The larva is grayish black, head black, the body rather grayish brown, with a broad, distinct, straight, cream-colored dorsal stripe. Hair rather long and, though coarse, somewhat soft and brownish. Spiracles white. The notes a'dd a more or less interrupted white subdorsal line, but it does not show in the blown or alcoholic specimens nor in the cast skins. The larva is a close ally of arge^ but differs in the absence (or reduction) of the subdorsal lines. The full life history is needed.

4. Arge is probably our best known species. The moth is peculiar and distinct with its broad vein linings, tooth-like bands and pale pink coloration. It is double brooded, the moths flying in May and July- August. . The full grown larva is not infrequently met with late in Fall or in warm days in Winter, having emerged from hibernation. It is grayish black with dorsal and subdorsal lines alike broad, distinct, cream-color, and a broken, waved subventral line ; the warts grayish, the hair rather long, coarse, but not bristly, brownish or gray. There are eighteen descriptions of this larva extant and I have notes on all the seven stages * of the first brood, taken from larvas that Dr. Seifert

kindly furnished me with in 1897. In the first stage the larva 'has simple seta3, except on wart iii on joints 5 to 13 which bears two hairs, no subprimary setae. The mature markings are outlined in stage II when the warts appear, and the successsive moults disclose no striking differences. I find the moths mate readily in the mating cage, the male flying in during the night.

It might be well to determine the number of larval stages under varying conditions, and especially of the second or hibernating brood, always giving the width of head for each stage. Otherwise the larvae are fairly well known.

Department of Agriculture numbers are 728P, 1045, 2451, 4117, 41 19 and 5865.

5. Qiienselii is strictly an arctic species. It occurs in the cold parts of both Europe and America, our nearest points being the sum- mits of the White Mountains of New Hampshire. The moth has the usual melanotic and blurred appearance of arctic forms and- the lining of the veins varies considerably, so that, in my seven specimens, I cannot always say that the median vein is broadly lined. However, the species is distinct enough in appearance from all other common forms.

The larva is known from European material ; Hoffman figures it black with pale dorsal line, the subventral hairs reddish. The only American description is one by Dr. Packard of a " supposed " larva of qiienscln, taken on the summit of Mt. Washington. I have had a larva very like this from the same place, sent me by Mrs. Slosson in 1895 ; but I failed to breed it. As neither Dr. Packard's larva nor mine correspond with the European qucnselii, and they are not un- likely to belong to some other species, we must await the result of positive breeding.

Any of the members visiting the summit next season would do well to search for qucnselii. It has been noted in Europe that the moth appears only in every other year.'* The same may be the case with us.

6. Nais is on debatable ground. This and the two following species are doubtfully distinct and often confused. It is not certain whether we have three, two, or but one species. The matter is further confused by wrong determinations and the larvre also are much mixed as I shall proceed to show. I have before me 50 moths that I

*Sandberg, Ent. Tidsk., IV, 16.

38 Journal New York Entomological Society. [Voi. vin.

attribute to //(^/V, 20 each oi phaierafir ^i\d vitfata {decorata) . The nais vary much in the degree of obsolescence of the bands and in the color of the hind wings ; but they all agree in having the costal edge of primaries narrowly black. The species is double brooded, flying in June and August.

Concerning the larva, I can find no description that can be reliably referred to this form. I have, however, a blown specimen from the Riley collection (no. ZZZ) ^^''^ notes from the Department of Agri- culture (no. 2582) with the moths correctly associated. The larva is brownish black or brown with a very faint, narrow, whitish, dorsal line, not at all contrasted. The hairs are short, stiff, grayish black, reddish subventrally.

Professor French describes the life-history (six stages), but his determination of the moth is doubtful. One specimen seems to have been ///rtZ^niA? anci of the other the determining character is not given.

The full grown larva may be taken early in Spring, hibernating under stones. It is a common species, and ought to be fully worked out soon.

7. Phalcrata resembles nais, but the costal edge is yellow and there is scarcely any tendency to the obsolescence of the markings. My 20 specimens are very uniform. This does not prove specific dis- tinctness, of course ; but I was impressed with the fact that a gap seemed to exist between this form and uais at the time that I was col- lecting both forms at Poughkeepsie, N. Y. I have taken plialcrata in August, and have a date of issue, March 30th (Dept. Agric. 2580), making it double brooded with hibernation as mature larva, as in 7iais. Concerning the larva. Professor French's descrijjtion, seemingly refer- al)le here, gives it a dorsal nankeen yellow line, expanded somewhat in the middle of each joint. This would be quite distinct from the other forms ; but the notes of the Department of Agriculture, of which I have the moth before me, an undoubted phakfata, are differ- ent. They give a black larva resembling virgo, but the warts not pol- ished ; no dorsal line is mentioned.

The members ought to settle this contradiction and work out the full life history of this interesting form.

8.- Vitfata (decoi-ata) is closely allied to piialerata. The costal edge is likewise yellow, but there is a great tendency to melanism ; the W-mark is lost in all the females and rarely complete even in the males. The hind wings vary from yellow to red, but tend to a very broad outer black border. The abdomen, too, is often largely black.

Mar.igoc] Dyar: On Larv^ of the Genus Arctia. 39

The species is a trifle larger than the two preceding. The appearance of my 20 specimens is quite different from //^a/.r^A?, but yet I have no strong character to separate them by. Professor French's description of the larva makes it black without a dorsal line. I have three alcohohc larvae (Dept. Agr. 2587 and Riley coll. 1 261) as well as descriptions (Dept. Agr. nos. 2544, 2581 and 2587). The bred mothsare vittata, but not all perfectly typical as in none of them, except no. 2544, is the abdomen broadly black. The larva of the typical vittala (no. 2544) is said to be black, body olive, the warts black and rough; hair brown, lighter in front ; spiracles orange. This agrees with Pro- fessor French. The others are the same ; but in no. 2581 ''an indis- tinct pale orange dorsal line" is mentioned and one of the alcoholic no. 2587 has a distinct, broad, broken white dorsal line. Of course these larvai may have been mixed ; but the matter is not decided be- yond question as to whether ///.//mr/^ or vittata has the larva with the dorsal stripes, or whether this is a specific character at all.

I believe some of the members are more familiar with these forms than I am, and I hope they will put their notes together for publication. Much evidence from many sources is needed in this connection.

9. Intermedia is often confused with virgo, but as I have shown you already, quite unnecessarily so. The moth inhabits the Atlantic states, but has a southern range. Specimens occur in New York, but I do not think it is common here or extends much farther north. It is simply an enlarged edition of parthenice, which replaces it in the north, the transverse bands more distinct and more frequently travers- ing the submedian bar. There are absolutely no firm characters between this 2^x1^ parthenice ; but the life history is entirely unknown, and it may be found to furnish some further points of difference. I recommend this species to your attention, as any information on the early stages will be worthy of note.

10. Parthenice is fairly common in the northern Atlantic states, northern New York, New Hampshire and Maine to Wisconsin : south- ward it is replaced by intermedia. The moth flies in August, some- what later than virgo, with which it is, usually associated. I think there is only one annual generation. The species is allied to inter- media, as I have shown ; but it is also very near to rectilinea. The veins are a little more heavily lined than in rectilinea with no ten- dency to obsolescence, and the bands are more or less bent, not rigid. The color of the hind wings, too, is a little more orange-red. Again

40 Journal New York Entomological Society. [Voi. viii.

partJienice comes very near anna. In fact, it has been suggested that ainm was only a form of partlienicc. Anna has yellow hind wings and a much greater tendency to melanism ; but the pattern of the fore wings is almost identical. Thus partlicnice is a central form with close allies on all sides, leading through recti It nea lo phxilira and the group without linings on the veins, and through anna to ornata and the western species.

The larva has been described by Saunders as black, with a flesh- colored dorsal stripe and yellowish warts and feet ; but this was many years ago, and the observation has not been verified. Larvre, which I have had from eggs oi parthenice, did not agree with this description, but were almost absolutely indistinguishable from those of vifgo. They were, however, much smaller and hibernated in the fourth or fifth stage, less than half grown; width of head .9 or 1.25 mm. I have not seen the mature larva, and it is possible that it may agree with Saunders' description, though I fear that this'is unlikely, as it is not customary for the dorsal line to reappear after it is once lost. The process is usually the reverse.

11. Anna is really the variety, being the rarer and aberrant form o( pc/stp/ione ; but the name was puljlished earlier. The second- aries are yellow with a strong tendency to melanism. In my 12 specimens, none have the outer black border broken through, and one has the wings wholly black. The fore wings are like pafthenice, but the longitudinal bands are occasionally very heavy and the submedian stripe usually runs closer to the median vein. The species is, un- doubtedly a good one, though very near to partlienice. It inhabits the dry oak woods of Long Island and New Jersey, extending well south, but also into northern New York, Missouri, Nebraska, Iowa and Wisconsin. It is never very common, though well distributed in its wide range. The moths appear in June, and I think there is but one annual generation. The larva is entirely deep black, with shining warts and stiff black hairs, alike in color throughout. I have described the life history up to hibernation (Psyche, viii, 53) which seems to occur in the last larval stage. This point is not certain, and hibernated larvae should be looked for in April or May, and the heads measured to determine whether there is any moult in the Spring.

12. Oithona (^rectilinea')^ is a puzzling form. We naturally

* Oithona Streck. is an aberrant form of rectilinea French, as I learn from an examination of Dr. Strecker's type.

Mar. 1900.] DyAR : On LaRV^ OF THE GeNUS ArCTJA. 41

associate it with the species with the veins lined, yet, except for this character, it is absolutely the same as phyllira. In fact, several of my old specimens are labelled phyllira, and this is probably the reason that the form was left undescribed by the early authors. Now, the character of the linings of the veins is not fixed in this case, as it usually is. I have two specimens in which the linings do not attain the outer margin ; others in which only the subcostal, median and internal veins are lined on basal portion, in fact true intergrades to phyllira. I feel quite certain that rcctiliiica is only a form ol phyllira ; just the same relation between them as between the western ornata and achaia ; but to clinch the argument, we must do some breeding to get either form from the other. I trust the opportunity will arise to some of us.

The larva ha? not been described and none of my 22 specimens are bred. The range is all over the eastern part of the country, New York, New Hampshire, Illinois, Missouri and Mississippi.

13. Phyllira is again a central form around which clusters much uncertainty. My ten specimens do not vary much. There is in some a trace of lining on the median vein, completing the links with recti- linea, and in a itw the bands are somewhat broken up and abbreviated; but it is the inner bands that are affected first and the W-mark remains the most distinct. The secondaries are very uniform with the narrow black edge, three submarginal spots and small discal spot, the latter sometimes absent. The species is southern in its range. I have noth- ing north of Maryland and most of my specimens are from Florida. This is surprising if we have to do with an alternative form of recti- liuca ; but may be due to the smallness of the collection, as phyllira is not often taken now. Or else it may be due to climatic causes.

The larva was figured by Abbot and Smith in 1797. There are no descriptions since. I have, however, blown specimens from the De- partment of Agriculture (no. 2494) and they agree sufficiently with Abbot's figure. The insect is brown-black, mottled, with shining dorsal warts and a distinct, pale yellow dorsal line that widens almost to spots in the center of each segment and is narrowed, or even broken in the incisures. The hair is short, black and bristly, grayish sub- ventrally.

Most of the details of the life history remain to be determined.

Celia Saunders (^franconia Hy. Edw, ) has been made a synonym of this species. It differs in the yellow secondaries with a strong ten-

dency to melanism, confluent basal spots being present. The range is northern. I have a specimen from northern New York and I know of no southern records ; but my material is extremely limited. Saunders describes the larva as brownish black, the hair black, brownish sub- ventrally and at the ends, abdominal feet yellowish. No dorsal line is mentioned and the larva would appear very distinct from phyllira. It needs thorough investigation.

Figurnta {/-pallida Streck. , cxcclsa Neum. ) has been made a variety o{ phyllira. It is a melanotic form, but the melanism affects first the outer borders of the wings, so that the W-mark is absent even when the other lines are bright and distinct and the secondaries have an even black border. The hind wings are either red or yellow. It is a southern form and is but rarely taken. It reaches southern New York where Mr. Graef collected a female and by fortunate breeding secured a number of examples. I have also from Staten Island larvce labelled figurata (Dept. Agr. , no. 2552) ; but none of the motiis are before me so that I cannot verify the determination.

Mr. Graef describes the larva as black, mentioning no marks. My blown larvK agree, but the hairs are a little brownish, and there is a very faint, straight, whitish dorsal line, broken or continuous, easily overlooked on cursory examination. In one of four alcoholic speci- mens the lime comes out very heavy and distinct ; but of course there may have been a mixture of species.

I see no essential difference between the larvoe of celia diwApigiirala; but the considerable difference oi pliyllira shows that the whole matter of synonymy as well as the life histories of the forms needs to be studied further.

14. Placenfia is a peculiar and distinct form inhabiting the South. The records are Georgia, Florida, Kansas and Texas. It may range further north. Indeed I should expect it would be found as far as Long Island in open, sandy districts ; but this may not be the case. The fore wings are black, diversified by only a few pale dots, rarely indicating the usual lines, but always broken up. The hind wings are much as mjigiirafa. I found the species at Miami, Florida, in the sandy pine barren and got the larva as far as stage III. The first stage was as usual in the genus, single hairs, except wart iii on joints 5 to 13, which bears two hairs ; no subprimary sette. In stage III the color was blackish without lines, the hair black, short and gray sub- ventrally. Abbot and Smith's figure of the full grown larva is gray,

the dorsal stripe red, yellowish and broken in the incisures ; head and hair black. There has been no verification of this figure ; and larvae that I got in Florida, which I thought -were placenfia, -were quite dif- ferent. However I did not breed them, and the matter is still open.

15. 6^/7/(7/(;? has two forms, very distinct at first sight, but intergrading. The typical ornata is without linings on the veins, and occurs sparingly in the southern part of the range of that species. I have it from San Francisco, Lake county and Mariposa county, California. The species as a whole ranges along the west coast from California to British Co- lumbia. I do not know the exact limits of distribution. The variety coiuplicata is dominant in Portland, Oregon. This species is the western representative of anna, from which it differs in the greater number of bands on the forewings and the tendency to orange of the hind wings. The spotting of the latter also runs somewhat differently. In the occasional disappearance of the vein linings, it resembles oithona-pJiyllira as already noted.

The larva (form achaia) has been described by Stretch, who makes it black with a double, somewhat waved, dull reddish dorsal line ; feet flesh color ; hair light brown, soft and silky. My larvae (from orna/a, Psyche, vi, 380-^=) were finally black with the subventral hairs reddish and no lines. They did not reach maturity, and I do not know Avhether they would have appeared like Stretch's or not ; I think not.

This species will have to be gone over again ; perhaps more than once.

*I described these as blakei [jievadeitsis), mistaking the female (?;'««/« for a moth of the group without the vein linings. Subsequent specimens from the same locality give the hint as to what the species really was.

44 Journal New York Entomological Society. [Voi. viil

1 6. Ohlitcrafa is only a name, and the species, if species it be, is not known beyond Stretch's description. As far as this description goes, it suggests a qiiensclii with red wings ; but I do not know if such a thing ever occurs.

17. Nex'cidcnsis is one of the forms that inhabit the arid region from southern California and Arizona, through Colorado and Nevada to eastern Washington and Montana. You may have thought that the eastern species were in some confusion, but they are quite plain in comparison with the confusion that exists here. ^Vhether there are half a dozen species, or only one, I am unable to say ; but I will treat them as in the last revision, making four species. Nevadeiisis with its forms incornipta and nevadensis is the most abundant. The veins are unlined, Ixit the transverse maculation is fully present, four bands be- side the W-mark. In one form the bands are rather narrow, in the other (incorn/pfa) broad. A^evadcnsis has the thorax black. It looks very distinct, and I have no intergrades ; but it occurs with the wings of both the narrow and broad banded forms and scattered all over the same regions. Besides Dr. Strecker has specimens with the black thorax and without it, said to have been bred from the same brood. Mr. Coquillett has had the larva of nevadensis (black thorax) in southern California and tells me that it is black with a broken dull white dorsal line ; the hair brown.* This is essentially the same as that of sitperha, the next species. Nothing is known of the early stages of the forms without the black thorax.

18. Siiperba was separated from nevadensis as the secondaries seemed redder. This character is not at all marked, and otherwise

* Arctin nevadensis Grote. Larva. Body black, with a purplish tinge, the portion below the spiracle lighter, more grayish, a broken, dull white dorsal line ; warts light gray, hairs issuing from them in spreading clusters, not concealing the ground color, mixed black and reddish or black and yellowish, the red and yellow hairs most numerous in the middle of the dorsum and low down on each side of the body and varying in color from a bright brick red to a pale straw yellow ; spiracles yellowish brown, ringed with lilack ; head black, the sulcus on top between the two lobes, usually the sides and lower margin of the cly- peus, and a dot at the base of each antenna, yellow ; mouthparts marked with yel- low anal and abdominal prolegs largely pale yellowish ; length, 36 mm. Found a great many from half to nearly full grown feeding upon varous plants at Santa Monica, Calif., March 14, 1891. Placed leaves of Alalva borealis in their cage, and they fed greedily upon them. One moth issued July 29th ; at this date two were chrysalids and ten were larvi-p. The remaining moths issued in August and September.

the markings are the same, except that the lines are niore broken up. The form comes from the rainy coast region of the Northwest. We have specimens from Easton, Washington, with a blown larva. This is black, dotted with pale, a white dorsal line broken into three small spots on each segment ; hair mostly brown, even well up on the back, short, bristly.

Gcnetira Streck. is referred here as a synonym, but it has the full banding, the bands rather narrow, and differs from the nevadenis form in that the secondaries have larger spottings. The thorax is lined. Jt comes from Colorado.

19. ]Villiamsii\% again the variety with defeniii na fa ^ewm. as the stem form, but the varietal name has priority. The form is distributed with nevadeiisis, but mostly in the higher altitudes or northern parts of its range. The black color of the wings has turned to a faded brown, except centrally, and the transverse bands are reduced, beginning at the base, to two, or but one, beside the W-mark. The secondaries are often considerably blackened. This may be the high altitude nevadensis, just as superba may be the rainy region form of the same species. The larvae are not known.

20. Favorita is a curious blurred form ; otherwise it is nothing but phyllira. I suspect that this is only phyliira migrated to the Rocky Mountain region. I have seen very similar specimens from Grand Papids, Michigan. The larva is not known.

21. Cerviiwides is not known to me by any specimens other than Strecker's types. It is a high altitude form, coming from Colorado. Professor Smith says " this will prove an undersized //y///;v7 with black secondaries, ' ' but he might as well have said an undersized williamsii or a race oi quenselii, •since to modify //y/Z/rrt; in this way would be to make another species of it. J suspect that this form is Dr. Packard's " quenselii'''' of the Hay den Reports. It is in any case a form modi- fied by cold ; but its relations must be left till further investigations. The larva is not known.

22. Blakci (^ihdanderiy^ is a small species with brown (not black) fore wings and yellow hind wings, marked like detenninata, or with even more bands. It comes from the arid region and is prob- ably widely spread in the colder parts of this region. The type of

*After examining. Grote and Robinson's type in the Academy of Nat. Sciences at Philadelphia, I find hlakei is what I had previously called bolanderi and not neva- densis.

46 Journal New York Entomological Society. [Voi viii.

bolandcri was taken at Mt. Shasta, California ; but my specimens, agreeing very well, are from Montana. The larva is quite distinct. Black, dorsal band vermilion red, pale in the incisures; segments white dotted posteriorly ; wart iii bright red at base, the subventral warts pale. Hair stiff, reddish subventrally. I have given the full life history in Proceedings of the Boston Society of Natural History, Vol. XXVI, page 153 (1S93).

23. Proxima is a distinct form inhabiting the arid region. I have taken it at Salt Lake City and it is very abundant in southern Cali- fornia. The sexes are quite dissimilar in appearance, on account of the different color of the hind wings. The species extends into Mexico. I would request collectors not to present specimens of this species to the National Museum, as we have them already by the drawer full.

The larva is black with a series of dorsal red spots, one on a seg- ment, each pointed before ; the hair is black, mixed with brown. I have described the life history (Ent. Amer. , VI, 117) and the Na- tional Museum has a dozen blown larva; prepared by Mr. Koebele at Los Angeles, California, and Ogden, Utah. It will not be necessary for you to waste much time on this common species ; but if eggs come to hand, fuller obser\ations may be made on stage I than I was able to make at the time I bred the species.

Finally I would call your attention to a few structural points that will assist in separating the larva; of Eiiprepia. As these are not generally given in descriptions I have been unable to use them, ex- cept in the few larvi^ that are actually before me. These points re- late to the size of wart i, the presence or absence of a shining base to wart ii and the distinctness of the barbules of the hairs. Eight species that are before me separate as follows, which will illustrate the way in which I suggest that these characters be used.

ADDITIONAL NOTES ON TRYPETIDiE.

By R. W. Doane.

It is with a good deal of hesitancy that I dare to take issue with so eminent authority on Diptera as Mr. Coquillett. But since his recent paper on Trypetid^ (Jour. N. Y. Ento. Soc, Vol. 7, no. 4) appeared I have been asked to say what I thought of the synonomy as therein set forth. As the paper shows evidence of having been hastily thrown together and as I still have before me all the types described in Vol 7 no 2 of the same journal it may not be amiss to call atten- tion to some of the points in the original descriptions that seem to have been entirely overlooked and perhaps add a few notes.

Spilographa setosa Doane differs from 5. flaiwnotata in the follow- ing particulars. -No trace of lighter markings on thorax ; dark in- stead of pale bristles on hind tibiae ; posterior femora with brownish bristles near tip; more brown on basal portion of the wmg ; bristles on the third vein extending beyond the anterior cross vein.

Trxpeta straminea Doane differs from T. ocadentaUs Snow m the following particulars.-Very much smaller, only about half as large ; dark reddish yellow instead of lighter yellow ; pile on thorax and ab- domen not so long or dense ; wings comparatively narrower. Every one of these characters is constant throughout a large series of both species. They can not possibly be confused.

Eurosta conspicrcata Doane differs from E. reticulata Snow m the following particulars—Smaller ; thorax lighter brown ; no light stripe on abdomen ; the ring is much longer in proportion to its breadth; the hyaline spots are larger and somewhat differently arranged espe- cially in the posterior portion of the wing, and there are not so many small yellow spots. I have only a single male specimen of this species but it is perfect and well preserved and looks so wholly unlike any of

48 Journal New York Entomological Society. [Voi. viii.

the specimens of E. reticulata that I have before me that I cannot but believe it to be a distinct species.

Eutreta iiora Doane differs from Loew's description of Tcphritis platyptcra in the following particulars. — Front not narrowed anteri- orly, eijuals much more than half the width of the head ; abdomen dark velvety brown with a narrow median longitudinal grayish line, but with no black spots ; third vein with bristles. Lowe's descrip- tion was drawn from a single badly preserved specimen, so of course there is a possibility of it not being accurate but as it stands it does not describe the specimen now before me.

Tcplwitis ca!ifor)iica Doane and Urellia pacifica Doane. — This of course is the worst blunder of the whole lot. To declare that two forms belong to the same species when they are so wholly unlike as to leave little doubt that they even belonged to different genera is carry- ing things a little too far. Indeed the differences are so great that to point them out would simply mean to rewrite the description of each one. So I refer to the original description. If they cannot be under- stood look at the pictures of the wings. There is no possibility of them being confused. Neither of them corresponds at all with the de- scription oi Euarcsta araneosa Coq., and as it is evident that the de- scription of T. califoniica and U. pacifica have not been closely studied when they were declared to be synonyms of this species it is not worth while again going into detail. Again I refer to the original description.

As to the true generic position of several of these forms I expressed myself as being in some doubt as all generic tables given heretofore were based almost entirely upon the wing markings and I did not have the original descriptions of all the genera before me. When, however, I could not determine by the wing markings to which of two genera any form belonged I studied the general characters of the body and placed it in the genus to which it seemed the most closely related. I believe by this method I came nearer indicating their true relationship than can be done by simply studying the wing markings alone.

REVIEW OF THE AMERICAN CORYLOPHIDiE,

CRYPTOPHAGIDiE. TRITOMID^ AND DER-

MESTIDiE, WITH OTHER STUDIES.

Bv Thos. L. Casey.

The following pages record the results of a number of studies made at various times during the year just coming to an end, and may pos- sibly be of some service to collectors in arranging their cabinets. The descriptions give only the salient characters of each species, and, in a genus such as the corylophid Groucviis for example, wherein the spe- cies mutually resemble each other very closely, can be appropriately limited to the few apparent differential characters. Further elaboration in such cases would prove to be largely repetition, and serve no really useful purpose in the present preliminary outline sketches, which are only intended to partially and imperfectly point the way. FOS.T Monroe, Va., December 14, 1S99.

Limnebius Leach. The minute species composing this genus have the body elongate- oval and convex, the very small sparse punctures of the upper surface bearing each a fine decumbent hair. The labrum is transverse, with the apex sinuate at the middle. The inferior part of the eye is well developed and prominent, with the individual facets convex, but the superior part is not more convex than the frontal surface, with the facets larger and perfectly flat. The antennae are partially received in repose in a very narrow groove between the eyes and the buccal open- ing, and, curving around the lower contour of the eyes, the club is

concealed within the deep depression for the eyes in the anterior part of the hypomera. The anterior coxte are separated by a narrow promi- nent lamina. Hind tarsi slender, the first two joints short.

This genus was investigated by the writer some time since under the name Limnocharis Horn, (Bull. Cal. Acad. Sci.). The male has the sixth ventral more elongate, sometimes as long as the two preced- ing combined or even longer, the seventh transversely impressed at base and the elytral apices transversely rounded. In the female the sixth ventral is not longer than the preceding, the seventh smaller and simple, and the elytral apices are frequently oblitjuely pointed at tip. The eighth segment, heretofore noted, is the projecting part of the dorsal pygidium, and does not belong to the venter. In most of the species the male seems to be much less abundant than the female.

The American species of the genus may be defined as follows from the female throughout : —

Elytra oval in outline, the sides arcuate 2

Elytra conical, truncate at tip, the sides straight 7

2 — Elytral apices in the female obliquely subtruncate ; pubescence rather long 3

Elytral apices in the female rounded ; last joint of the maxillary palpi fusiform 4

conlciventris Csy.

June i,oo.] Casey : On North American Coleoptera. 53

Alutaceiis is the largest species, being fully 1.6 mm. in length, and coniciventris the smallest. The latter greatly resembles a species from South Africa, taken some years ago by the writer. Piceus is very abundant in the coast regions from Monterey northward, and the fe- male described by me as, politiis does not seem to differ ; it is the only species before me which is represented by both sexes. Individual ex- amples vary but little among themselves in point of size.

STAPHYLINID.E.

The genus Homvusa of Kraatz, represents an isolated group of the subtribe Aliocharina, containing a number of genera for the most part monotypic as far as known. Those before me may be characterized as follows : —

Antennae 1 1 -j ointed 2

Antennae lo-jointed 4

2 — Prothorax broadly and evenly rounded at the sides, the apical angles rounded 3

Prothorax broadly angulate at the sides at the middle, the angle rounded, the apical angles obtuse but not rounded, the base arcuate, not sensibly sinuate toward the angles, which are obtuse but not rounded ; two basal tergites broadly, equally and deeply impressed in about basal half; fine elevated anterior bounding line of the metasternum strongly and narrowly arcuate anteriorly at the middle, the mesosternal process long and finely acuminate, extending to almost opposite the apices of the coxre; infraorbial elevated line of the head feeble and obtuse ; an- tennae very strongly incrassate ; basal joint of the hind tarsi distinctly shorter than

the next two combined; [type crassicorttis Csy.] Myrmobiota Csy.

3 — Base of the prothorax transverse and broadly bisinuate, the basal angles nearly right and not at all rounded ; two basal tergites narrowly, deeply and rather abruptly impressed along the basal margin ; antennas moderately incrassate ; an- terior marginal line of the metasternum transverse and only just visibly and very broadly arcuate anteriorly at the middle, the mesosternal process as in Alyrmo- biota ; head with the infraorbital ridge very fine, and, between it and the eye, having two additional broad feeble and parallel ridges ; basal joint of the hind tarsi fully as long as the next two combined ; [type acin?ii>iata Mark. ].

Homoeusa A'rlz. Base of the prothorax arcuate, becoming feebly sinuate near each angle, the latter slightly obtuse and distinctly, though narrowly, rounded ; basal tergites not im- pressed at base ; antennse feebly incrassate, the last joint longer than the two pre- ceding combined and somewhat compressed apically ; mesosternal process angu- late, much shorter than in the two preceding, the metasternal line obscured in the type ; infraorbital ridge fine but distinct, the additional ridges of Homceiisa wanting ; basal joint of the hind tarsi distinctly shorter than the next two com- bined ; pubescence longer and more conspicuous ; [type . riiiitiila Csy. infra.].

Soliusa, gen. nov.

54 Journal New York Entomological Society. lvoI. viil

4 — Prothorax as in Honiaiisa, the base transverse and bisinuate, the angles right, not rounded and somewhat prominent, tlie sides arcuate and apical angles very broadly rounded ; basal tergites as in Soliiisa, not impressed at base ; eyes smaller than usual, the antenna; rather strongly incrassate, the tenth joint probably formed by the fusion of two, but not relatively longer than in Hoinosusa ; infraocular ridge tine but abruptly and strongly elevated, the additional ridges wanting ; basal joint of the hind tarsi as long as the last and a little longer than the next two combined ; pubescence moderate in length as in Homaiisa ; [type expansa Lee] Decusa, gen. nov.

The type of Soliusa may be briefly described as follows : —

Moderately stout and depressed, the head nearly three-fifths as wide as the prothorax, with the eyes slightly prominent ; antennae but little longer than the width of the body ; prothorax three-fourths wider than long, equal in width to the elytra and distinctly shorter, the sides rotundato-convergent anteriorly ; abdomen at base nearly as wide as the elytra, acuminate, the sides straight ; fifth tergite at apex three-fifths as wide as the first ; color throughout pale brown, the abdomen a little darker, the surface rather shining and quite feeble punctulate ; pubescence con- spicuous but subdecumbent as usual. Length, 1.75 mm. ; width 0.63 mm. New York crinitula, sp. nov.

Individuals seem to be rare in all of these genera and probably have throughout a more or less complete symbiosis with ants. Mynnobiota crassiconiis and Decusa expansa have both been sent to me by Mr. Wickham as having been discovered in ant-nests.

Mr. Wasmann (Tijd. v. Ent. XLI), states that Myrmohiota Csy. (Col. Not. V, p. 594) is identical with Iloiiuviisa Krtz., citing speci- mens collected by Mr. Wickham and forwarded to him through Mr. Schmitt. There is manifestly some mistake in identification, how- ever, and my friend's remarks must refer to the species here described under the name Soliusa crinitula or to one closely al- lied thereto \ but if the latter surmise prove to be cor- rect, I am forced to differ in opinion concerning the status of that species, for a study of the basal tergites of the abdomen, form of the mesosternum and thor- acic base, and other characters, show that crinitula. Fig. I.— Prothorax also, is gcnerically distinct. In regard to Mymwtu'ota, Myyiionota an ^]-jgj.g ^^^ ^g j-^q (Joubt of its wide isolation from IIo- nuvusa, as an inspection of the small accompanying diagrams of the prothorax will abundantly demonstrate, the upper figure referring to ^lyrniobiota and the lower to Honuvusa acuminata. That Mr. Wasmann has fallen into an error in identification, is further- more evident at once from his statement that crassicornis (Wasm. nee

Juneigoo,] CaSEY : On NoRTH AMERICAN COLEOPTERA. 55

Csy.) differs from acuminata, among other minor characters, in hav- ing finer and denser pronotal punctuation, while, as a fact, the pro- notum is much more coarsely punctured in crassiconiis Csy. than m acuminata.

Chitosa gen. nov. The type of this genus is Dinarda nigrita Rosh., which differs from Dinarda, as represented by mdrluli and dentata, very profoundly in antennal and tarsal structure, as well as in the entire form of the pro- thorax and nature of the sculpture. In Dinarda dcntata the pro- thorax is broadly and evenly bisinuate at base, and the sides near the basal angles 'are parallel and nearly rectilinear, the antennce cylin- drical, becoming somewhat acuminate at tip, and the basal joint of the hind tarsi but little longer than the second, the first four joints m fact diminishing only just visibly and quite regularly in length. In ni-rita, on the other hand, the base of the prothorax is arcuate, becom- ing emarginate at each side, and the side margin is emarginate near the basal angles ; the antenna are gradually and strongly incrassate, a form wholly foreign to Dinarda, and, finally, the hind tarsi are very remarkable in structure and wholly different from any I have seen elsewhere in the Aleocharini. The basal joint is thicker than the remainder, darker in color or more highly chitinized, cylindrical and lon-er than the next three joints combined, the latter short, gradu- ally''diminishing in length and obliquely truncate at their apices, the fifth as long as the preceding three together and more slender. These characters prove that Chitosa is a genus quite isolated from any other ; it is however related to Dinarda. It occurs in Spain.

SCAPHIDIID.E. This family seems to be very much better represented in America than in Europe, and a number of new forms have been discovered since my revision (Col. Not., V.).

Scaphidium Oliv. The species before me seem to be five in number, piceum being quite evidently distinct from the maculate forms ; they may be de- fined as follows: —

Elytra black, each with two pale subexternal spots •••■2

Elytra uniform in coloration throughout, with a few d.scal coarse punctures m short

The two species now known to me may be distinguished as fol- lows : —

Broader and somewhat oblong-oval, castaneous in color, the legs paler ; antenme pale throughout. Length 3.2-3.3 mm. ; width 1. 9-2.0 mm. North Carolina. \_siibstriatiini Reit] flavipes Lee.

ater, sp. nov.

The characters given by Reitter to distinguish siibstriatuDi (Ver- hand. Nat. Ver. Briinn, XVIII) are completely those oi flavipes, and the name must therefore be relegated to synonymy.

Scaphiomicrus, gen. nov.

The species described by LeConte under the name Scaphisonm pusilla, must form the type of a distinct genus because of the shorter and thicker antenna;, situated at a greater distance from the eyes,

June .000] CaS^Y 1 On NORTH AMERICAN C. LEOPTERA. 59

which are notably smaller, the shorter tarsi, and especially, because of the radically different form of the post-coxal plates of the abdomen. These plates in Scaphisoma are very short and only developed inter- nally, the bounding arc extending outward externally, very gradually approaching the base of the segment, while in Scaphiomicnis the plates are more nearly semi-elliptic, having the outer part of the bounding curve directed upon the base without change of direction toward the sides of the body, somewhat, in fact, as in the subgenus Pullns of the Coccinellidje. The species are all very much more minute than in Scaphisoma, and those which are represented before me may be dis- tinguished by the following characters : —

Abdominal plates ahnost evenly parabolic in form, the apex more broadly rounded and the outer side more arcuate and approaching the base scarcely less obliquely

than the inner side ; sutural line of the elytra not flexed outward basally 2

Abdominal plates more narrowly rounded at apex, the external branch of the bound- ing curve much less arcuate than the internal, and directed almost perpendicu- larly upon the base ; sutural line of the elytra flexed outward at base, parallel to

the basal margin ; elytra blackish, gradually and broadly pale toward tip 5

CORYLOPHIU.E.

The Corylophid?e constittite a small family, evidently allied to the Silphidffi, as shown by antennal structure, and, like them, display great variety in external habitus ; they are, however, remarkably homogeneous among themselves in sternal and abdominal structure. In Orthoperus a relationship with Scaphidiidse can be observed, and there are some characters, such as the 4-jointed tarsi with the third joint small, the post-coxal plates of the Corylophini and the project- ing rounded pronotum of the Parmulini — homologous with Crano- phorini, — which proclaim an indubitable relationship with the Coc-

cinellidas. The chief difference in tarsal structure between these two families resides, indeed, simply in the freedom of the third joint, this being generally anchylosed to the fourth in Coccinellid^. The anterior coxa^ are narrowly separated, displaying variations which serve to define tribal groups, and the cavities are broadly closed be- hind ; the intermediate are more widely separated and the posterior mutually very remote. The scutellum is always distinct, though small, the abdomen hexamerous, the first segment being much the longest and the palpi short, stout and acuminate. The American species may be assigned to four tribes as follows : —

All of these tribes occur on both sides of the continent, but in the first tribe the genera with 9-jointed antennae are the only ones which have thus far appeared in the Pacific district.

CORYLdPHINI.

The species of this tribe may be readily known by their rounded or oval convex form and shining glabrous integuments. The genera may be separated as follows : —

Antennae ll-jointed, inserted between and near the eyes, widely separated at base, the eyes larger and coarsely faceted ; epipleurae rather wide and inflexed 2

Antennts 9-jointed, inserted more anteriorly and more distant from the eyes, which are smaller and less coarsely faceted ; basal joint shorter ; epipleura; extremely narrow or subobsolete, not at all inflexed ; labrum broadly rounded ; prothorax emarginate at apex, the head in great part exposed ; post-coxal plates very short ; tarsi slender 5

2 — Head very deeply inserted within the prothorax, the anterior margin of which is evenly rounded and strongly descending ; post-coxal plates large, with rounded outline, the subbasal discal line of the metepisterna very oblique ; labrum rounded or subquadrate 3

Head partially protruded and less concealed by the overhanging margin of the pro- thorax ; post-coxal plates very short, the subbasal line of the metepisterna nearly transverse ; labrum small, triangular, with the apex acuminate; tarsi dilated 4

3 — Post-coxal plates of the abdomen more strongly rounded, the external part of the bounding line directed upon the base well within the sides ; third antennal joint elongate, longer than the second Bathona

Post-coxal plates of the abdomen less arcuate posteriorly, the bounding line extending to the sides of the body ; third antennal joint elongate but shorter than the sec- ond Corylophodes

4— Head entirely concealed from above, the prothorax almost evenly rounded ante- riorly and more descending, the margins not distinctly thickened and the hind angles acute and somewhat more posterior than the median parts of the base ; maxillary palpi moderately stout, regularly acuminate Qronevus

Head partially visible from above, the prothorax sensibly sinuate at apex, the margins with a distinct thickened bead and the hind angles right ; maxillary palpi very

''°"^ Rypobius

5— Anterior tibiii; flattened, the external edge acute, the axial line feebly arcuate

throughout; body larger Eutrilia

Anterior tibia; slender, inwardly bent distally ; body very minute Orthoperus

I have restored the original spelling of Rypobius, although it may not be etymologically correct. The European Morouillus of Du Val is identical, having similar structure and habits.

Bathona, gen. nov. In this genus the body is broadly oval, convex, polished and gla- brous, with the edges of the pronotum subexplanate and diaphanous, and the hind angles not posteriorly produced. The tarsi are long and are compressed toward base. The species may be defined as follows : —

Body moderately convex, the sides and apex of the pronotum widely subexplanate ; antennal club large

Body very strongly, globularly convex, the limb of the pronotum very narrowly sub- explanate ; antennal club rather less developed ' . -.

2— Elytral punctures small and sparse but very distinct, impressed, each bearing, as usual, an excessively minute fine decumbent hair, black, the pronotum piceous- black, the edges broadly transparent and hyaline ; under surface paler, the legs and antennne rufescent. Length 1. 35 mm. ; width 0.9 mm. North Carolina (Asheville) carolinae, sp. nov.

Elytra] punctures smaller and almost efiaced ; body smaller, black, the pronotal limb broadly transparent and hyaline ; under surface and legs paler. Length 1. 1 mm. ; width 0.75 mm. Virginia (Norfolk) virginica, sp. nov.'

3— Impunctuate, piceous in color, the edges of the pronotum narrowly transparent and hyaline, the disk gradually darker toward the middle and base. Length l.o mm.; width 0.78 mm. North Carolina ( Asheville) COnvexa, sp. nov.

Smaller and with feeble but visible traces of punctuation, piceous or testaceous in color, the under surface and legs more flavate. Length 0.8 mm ; width 0.7 mm. Penn.sylvania (near Philadelphia) spharicula, sp. nov.'

Individuals are rare, but viro^huca is represented before me by a number of examples, which exhibit no noteworthy variability.

Corylophodes Maifh. As in the preceding, the antenna; in this genus have five small com- pacted and gradually wider joints between the third and the first joint

of the club, and there is no vestige of an enlargement of the second joint before the club as there is in Rypobiiis, Gro?ieviis and Ortho- penis. The structure of the shaft differs in fact very radically, and, in this way, these genera are widely isolated. Corylophodes resembles Bathona in general structure, but, besides the characters indicated in the table, it differs in the generally more narrowly oval form of the body, shorter and less developed prothorax, finely margined along the basal lobe, and more slender and less coarctate five antennal joints immediately succeeding the third. The tarsi are nearly similar, but the anterior are feebly dilated in the male. The three species before me may be thus distinguished among themselves: —

Elytral punctures sparse but rather coarse, deeply impressed and very distinct, black- ish-piceous, the limb of the pronotum broadly transparent and hyaline ; legs and antenna; paler. Length 0.9 mm. ; width 0.72 mm. Rhode Island, Pennsyl- vania and North Carolina (Asheville) marginicollis Lee.

Elytral punctures extremely minute and subobsolete 2

2 — Form narrowly oval, rufo-piceous in color, the pronotum with broad hyaline margin as in the preceding and succeeding species. Length 0.85 mm. ; width 0.65 mm. Florida imputictatus, sp. nov.

Form more broadly oval, black, the legs, trophi and antennae pale ; prothorax trans- verse, the basal angles obtusely blunt as usual. Length 0.8-0.9 mm. ! width 0.7-0.75 mm. Texas (Brownsville) subtropicus, sp. nov.

As pointed out by Mr. Matthews, the distinguishing feature of Cory- lopJiodcs is the slender third antennal joint shorter than the second, but the author makes no allusion at all to the remarkable post-coxal plates. The genus as extended by its author in the " Monograph" is very composite, and I am unable to place the C. scJiwarzi, described therein from California.

Qronevus, gen. nov. This and the succeeding genus differ very greatly from the two pre- ceding, in the very short and almost obsolete post-coxal plates, the meso-coxal being even much less developed than in OrtJwpcrus, but the subtransverse line at the base of the metepisterna is present as in that genus ; the comparatively wide and steeply indexed epipleurae distinguish them at once however from Oiihopefus a.\\6. Eutri/ia. They also differ quite radically in antennal structure, and from all others of the tribe, in the shorter and slightly dilated tarsi. In Grotievus the limb of the pronotum is hyaline and moderately widely subexpla- nate, the base not margined, and the hind angles are acute and dis-

tinctly though not abruptly produced posteriorly. The European Peltimis and Corylophiis differ in having very narrow horizontal epipleurae and more slender tibiae.

The species are somewhat abundant but closely allied ; those in my cabinet may be recognized by the following characters : —

Elytra finely and sparsely but more or less distinctly punctate 2

Elytra impunctate 5

2 — Elytral punctures very minute throughout 3

Elytral punctures strong, especially on the descending flanks ; body smaller, more rounded, very strongly subglobularly convex, blackish, the pronotum paler, with narrow hyaline limb. Length 0.8 mm. ; width 0.65 mm. Iowa.

SticticUS, sp. nov.

3 — Antennal club blackish ; body more strongly and globularly convex, black, the

pronotum slightly piceous, with narrow colorless hyaline margins ; scutellum

Canada (Ottawa) fuscicornis, sp. nov.

Antennal club very pale, not differing in color from the shaft, body rather less con- vex — 4

4 — Blackish, the pronotum rufo-piceous, sometimes entirely pale from immaturity ; elytra but little more than twice as long as the prothorax ; scutellum twice as wide as long. Length 0.8-0.9 mm. ; width 0.63-0.75 mm. Massachusetts, Rhode Island,

New York and New Jersey truncatus Lee.

Paler, piceo-testaceous, the prothorax still paler, form more elongate-oval, the elytra much more than twice as long as the prothorax ; scutellum less transverse and somewhat ogival ; elytral punctures still finer, almost completely effaced pos- teriorly ; size a little larger as a rule. Length 0.95 mm. ; width 0.8 mm. Iowa

and Nebraska hesperus, sp. nov.

5 — Blackish, the pronotum and elytral suture rufescent ; elytral margin at and near the humeri more widely subexplanate than in the preceding species. Length o. 78-0.85 mm. ; width 0.65-0.75 mm. Virginia (Norfolk and Fort Monroe)

laevis, sp. nov.

Individuals of the various species are much more abundant than in the two preceding genera, as is also the case in Rypobiiis.

Rypobius Lcc. The body in this genus is evenly oval and rather strongly conve.x, the pronotum evenly declivous toward the limb, which is not reiie.xo-expla- nate and not transparent or hyaline at the edges ; the hind angles l)eing right and the apex sensibly sinuate indicates a closer affinity with Or- ihoperus. The integuments are minutely reticulate, and each of the very minute sparse punctules bears a small and very fine decumbent hair. The scutellum is less than twice as wide as long and is para- bolic in form. The tarsal claws are rather long, slender and arcuate, with a feeble internal dilatation at base.

Juneigoo.] CaSEY; On NORTH AMERICAN COLEOPTERA. 65

The genus Glceosoina, of Wollaston, occurring in the Island of Madeira, which has been considered to be identical with Rypobiiis, is altogether distinct, not only in its lo-jointed antennae and type of elytral sculpture, but in its habits and gait, the single species of Gkvosoina taking refuge under stones and running with great velocity when disturbed — habits wholly foreign to Rypobiiis. It may however be placed near Rypobiiis in a tabular arrangement of the genera of the family. A Spanish specimen sent me by Mr. Reitter under the name Rvpobiiis ve/ox, differs from the true Rypobiiis also in the elytral epipleurje, which are inclined upward and not at all inflexed, and also in the hind angles of the prothorax, which are acute and sensibly pro- duced posteriorly. I am unable to count the joints of the antennas with certainty in this example.

The two species of Rypobiiis before me may be distinguished very readily as follows : —

Base of the prothorax ahnost rectilinear, piceous, the prothorax and under surface paler; micro-reticulation of the upper surface very deep, the lustre somewhat alutaceous. Length 1. 0-1.2 mm.; width 0.7-0.85 mm. Rhode Island, New- Jersey and Virginia (near the ocean beaches) marinus Lee.

Base of the prothorax distinctly bisinuate, blackish, the pronotum mfescent ; legs, an- tenuK and ti'ophi flavate, polished, the micro-reticulation of the upper surface almost completely eftaced ; size very much smaller. Length 0.6S mm. ; width o 5 mm. Texas (Columbus) minutus, sp. nov.

In both these species the first abdominal segment is as long as the next three combined. Miiiiitiis must bear some resemblance to the Central ^VL\Qx\z2iXv guatemalcnsis Matth., but differs in sculpture.

Eutrilia, gen. nov. The single representative of this genus resembles a very large, broadly oval Ortiiopcrus, and is evidently very closely related, being identical in the form of the prothorax and in the structure of the head, coxje and under surface. It however differs in the form of the an- terior tibice, as indicated in the table, and in the virtual absence of any trace of epipleurre, these being indicated only by a slight thicken- ing of the elytral margins due to the very minute marginal bead. The meso-coxal plate is rather well developed, but the metacoxal plate is extremely short as in Orfliopenis. The intermediate tibiae are slightly thickened externally just beyond the middle with arcuate outline, the posterior straight and the tarsi slender, the claws small, arcuate and very slender. The first ventral segment is as long as the next four

combined. The integuments are micro-reticulate and very finely punctate, each puncture bearing a small decumbent hair, these how- ever being a little longer and more conspicuous than in Rypobius. The scutellum is well developed, with broadly parabolic outline, and the elytral suture is not at all margined. The wings are well de- veloped, the fringing hairs very short. As in some species of Ortho- perns, especially sciitellaris, there is a feeble impressed longitudinal line on each elytron near outer fifth or sixth, extending from the base for a short distance : —

Oval, convex, moderately shining, brownish-testaceous in color throughDUt, the pro- thorax moderately developed, the base broadly parabolic, the sides strongly con- vergent, moderately arcuate and continuous in curvature with those of the elytra; punctures not distinctly visible under a hand lens of moderate power. Length 0.95 mm.; width o.S mm. California bruonea, sp. nov.

Orthoperus StepJi. The species of this genus are among the most minute of the Coleop- tera, and may be readily recognized by their oval, moderately convex form, exposed head and 9-jointed antennce, the fifth joint being gen- erally notably longer and sometimes thicker than the sixth. The epipleurre are represented by a narrow side margin of the descending flank, delimited by a fine line. The integuments of the body are more or less shining, micro-reticulate and virtually glabrous. The pronotum is very finely and feebly margined at base, the flanks not greatly descending, becoming very narrowly and feebly reflexo-expla- nate toward the basal angles, which are nearly right, not at all pro- duced posteriorly and narrowly rounded. The scutellum is dis- tinct though small and generally parabolic in shape. The species are rather numerous but closely allied among themselves as a rule ; those before me may be recognized as follows : —

Elytral suture not margined except posteriorly 2

Elytral suture finely margined to the scutellum 8

2 — Elytra without trace of punctuation of any kind, the minute reticulation distinct ; body much larger than usual, evenly elliptical, glabrous, pale brt>wn in color throughout, the meta.sternum impunctate and with very .sparse and microscopic

hairs. Length 0.82 mm.; width 0.62 mm. Colorado princeps, sp. nov.

Elytral punctures wanting but replaced by very small, sparse and V-shaped scratches ;

size rather large 3

Elytral punctures normal, being well-detmed points but always very minute and sparse ;

size small or very minute 4

3 — Form somewhat oblong and narrowly oval, black throughout, the legs and antennae rufescent ; micro-reticulation distinct ; metasternal punctures sparse but distinct.

Sericoderini. This tribe is well differentiated from the preceding in the oval pu- bescent body, with more extensible abdomen and absence of distinct post-coxal plates, and from the following in the non-explanate limb of the pronotum ; from both it may be distinguished by the lo-jointed antenna? and shorter basal segment of the abdomen, this, in the ex- tended condition, scarcely equaling in length the next two together. There is but a single genus.

Sericoderus Sfc/^h. The species of this genus are so closely allied among themselves that it is scarcely possible to detect structural differences of any kind, and the names given below might be considered to represent subspecies of a single type form. The head is completely concealed from above and moderately deeply inserted, the pronotum broadly rounded at apex and with the hind angles acute and considerably produced pos- teriorly. The antenna; are slender, with the basal joint narrowly oval and inserted in shallow frontal fovea; at a slight distance from antero-internal margin of the eyes, the latter usually well developed and coarsely faceted. The frontal margin is feebly sinuato-truncate and the labrum short and broadly rounded. The tibia; and tarsi are slender, and the elytral epipleura; narrow, becoming strongly inflexed toward base. The following forms seem to be worthy of distinctive names : —

Species of the Atlantic and Gulf regions 2

Species of the Pacific slope 5

2 — Elytra more strongly narrowed from base to apex 3

Elytra feebly narrowed, the form more quadrate 4

debilis, sp. nov.

When discovered, individuals are rather abundant. Sericodcrus is said in the " Biologia " to have the antenna ii-jointed, but these organs are quite evidently lo-jointed in our species, and the details given by Mr. Matthews for the antenna of ^. latus show that it should properly form a genus distinct from Sericodd

cms.

Parmulini. The numerous species of this tribe can be recognized at once by the oblong or oval and less convex pubescent body, more or less widely subexplanate at the lateral and apical limb of the pronotum, and the rectangular thoracic angles. The genus Saciiim of LeConte, is said by Heyden, Reitter and Weise to be the same as Parmuliis of Gund- lach, but, as the LeContean Saciiun is composite, I am in doubt as to which if 'any is the true Parmulus and have therefore not adopted the name for any one of our genera ; it is, however, retained for the tribal designation. The three genera before me may be identified by the following characters : —

Antenna 1 1 -jointed ; prosternum well developed in front of the coxce, the posterior margin of the buccal opening deflexed at the middle, forming a broad mfenorly

vertical liguliform process ••"•

Antennae lo-jointed ; prosternum extremely short in front of the cox^^e, the buccal

These genera are all widely distributed over the continent, but Sa- cittm has not yet been found near the Pacific coast line, although occurring in Utah ; it is more northern in habitat than the other two. Molainba may perhaps prove to be the same as Paiiiuihis, but at pres- ent I have no means of determining this.

Previous authors aiipear to have entirely overlooked the very con- spicuous vertical ligula at the hind margin of the buccal opening in Saciiiin and Molamba, a character wholly wanting in Arthrolips.

Sacium Lcc. In this genus, and the next, the limb of the pronotum is broadly retlexo-explanate antero-laterally, and is scarcely at all so at the mid- dle of the apical margin, while in Arthrolips the edge seems to be more narrowly and evenly reflexed throughout the external circumfer- ence. Saciui/i, as understood by Mr. Matthews in the " Monograph," is composite, and higubre should have been assumed as the type. The genus includes some of the largest species of the family known to me, and the four represented in my cabinet may be thus defined in brief: —

Prothorax as long as wide or very nearly ; elylral punctures and pubescence rather sparse 2

Prothorax shorter and more transverse, much wider than long in both sexes ; elytral punctures and pubescence dense 4

2 — Elongate, twice as long as wide or very nearly, the elytral punctures smaller and rather sparser, piceous to blackish in color, with the usual two pale patches at the apex of the pronotum. Length 1.75-2. i mm.; width 0.9-1.0 mm. Colo- rado montanum, sp. nov.

Less elongate, always distinctly less than twice as long as wide, the elytral punctures stronger and less sparse 3

3 — Piceous in color to blackish, the elytral suture sometimes slightly paler. Length 1.6-1.S mm.; width 0.85-0.9 mm. Lake Superior lugubre Lee.

Deep black, the suture not paler ; body a little larger and relatively broader. Length 1.7-2.0 mm.; width I.o-I.l mm. Utah (southwestern) nigrum, sp. nov.

4 — Body rather smaller, piceous-brown in color, the under surface and legs still paler. Length 1.65 mm.; width 0.S5 mm. Lake Superior obscurum Lcc.

The elytra are uniform in color throughout and there is an entire absence of the paler maculation so characteristic of the two following genera.

The genus represented by Clypcastcr >naderie Kr. (^piisilliis Woll., necGyll.) is radically distinct from Sacium in the structure of the an- tenna; as figured by AVollaston, and 1 would propose the generic name Clypeastodes for that species .

Arthrolips Ei-icJis. This genus resembles the last in the outward habitus of the species, but these are in general much more minute and more narrowly oval or oblong-oval and perhaps a little more conve.\. In the structure of the anterior parts of the prosternum and of the antennre it is radically dif- ferent. The species are nearly as numerous as those of Molainba, and are equally widely disseminated over the more southern parts of the Lhiited States ; as far as known to me they may be distinguished by the following characters : —

There may be some closely allied species included in the material before me which is referred to decolor, but in any e\ent they would be so doubtfully distinct that there could be no advantage gained in separating them ; there can be little or no doubt of its identity with the Sac ill /It ealifornieuin^ of Matthews.

The antennce in Arthrolips occasionally appear to have only nine joints, the slightly elongate third joint followed by three instead of four minute joints, but this appearance may be due simply to the diffi- culty in observing these organs in their natural position.

^-Enigmaticini.

The general habitus of the itw species comprising this tribe is wholly different from that of the preceding tribes, the body being narrow and somewhat as in Corticaria. There has been but one genus characterized thus far : ,

^nigmaticum Mattli. The body is parallel, moderately convex, the head entirely exposed and but slightly inclined, the eyes moderate in size, convex, with rather coarse convex facets as usual, the antennae inserted at some dis- tance from their antero-internal margin in angulate emarginations of the front. The prothorax is narrowed at base and truncate at base and apex, the apical angles very obtusely rounded, the basal more distinct but obtuse, the elytral suture strongly and widely margined, the line extending along the well-developed and transversely triangular scutel- lum nearly to outer third of each elytron. The anterior coxre are small and distinctly, though not broadly, separated, and the pro- sternum is largely developed in front of them ; the middle coxae are rather narrowly, the posterior very widely, separated, the legs slender, ' with the tibias somewhat clavate and the tarsi rather slender, with the basal joints small. The basal segment of the abdomen is about as long as the next three combined. The two species known to me are minutely reticulate and subglabrous, each puncture bearing a very small but distinct cinereous hair ; they may be defined as follows : —

Prothorax broadly subangulate and widest at the middle, the sides straight or very feebly sinuate thence to the basal angles ; body dark castaneous, finely and sparsely but very distinctly punctate. Length 0.75-0. q nun.; width 0.42- 0.5 mm. California (San Francisco) californicum Cn .

Prothorax almost evenly rounded at the sides, becoming much more convergent toward apex, the latter scarcely more than half as wide as the base, the disk widest be- hind the middle and narrowed but slightly at base ; punctures sparse and very minute, those of the pronotum more visible and having the form of minute trans- verse arcs, enclosing each a very minute hair ; color dark brown ; size smaller and rather more slender inform than • alifoniicuin. Length 0.6 nnn.; width 0.25 mm. Florida elongatum Lee.

Eloiigatiini was described as an Orf/iopcn/shy LeConte, and the type is not before me at present, but a drawing from this type made by me some years ago seems to show that the prothorax differs so greatly in outline from that of californicum as to indicate some divergence of a generic nature.

In the recent posthumous "Monograph of the Corylophidje and Sphaeriidae," page 35, Mr. Matthews has fallen into a singular misap- prehension, as my letter to him will undoubtedly show. My language was not by any means intended to imply that his yEnii:,»iafici///i ptilioides was identical with Orthopenis elongatiis, but simply stated my conviction that the clongatus of LeConte is an ,-EiiigiiiafiLiiin.

are many minor errors throughout this important monograph, which would doubtless have been avoided had the author lived to conduct it through the press. SpJuvriiis poUtiis, for example, on page 214, is at- tributed to the author as a new species, whereas it was in reality de- scribed by Dr. Horn many years ago.

CRYPTOPHAGID^.

Under this name have been grouped two closely allied types of so- called Clavicornia, comprising numerous genera and species. The body is small to minute in size, oblong or oval, more or less convex and generally clothed with coarse subdecumbent pubescence, with additional longer and more erect hairs arranged serially on the elytra in many genera, similar to those of the Tritomida^. The tarsi are pentamerous, becoming heteromerous in the males of certain genera as in certain CucujidtC, and the anterior coxa^ are oval, mod- erate in size, smaller and more deep-set than in Tritomidce, becoming decidedly transverse in the Ephistemini, and having an external trochantin. It is this form of the coxk which principally distinguishes the family from the Cucujida;, where the anterior coxai are still smaller, equally or still more deeply inserted and subglobular. The family is also unmistakably allied in many characters, especially evident in the AtomariiuK, to the Scydmasnida^. Among these resemblances may be mentioned the basal impressions of the pronotum, so characteristic of the CryptophaginK, the side margins of the latter in Cccnoscelis, and the recurved ventral sutures of that and some other genera, the elon- gate form of the trochanters, alternating long and short joints of the antennal shaft and slender pentamerous tarsi. The only serricorn character which is especially evident is the asymmetric antennal club of EphistcDius.

Probably the most essentially peculiar structural feature of the Cryp- tophagidfe, although a distinguishing character of the Silvaninre as well, is the modification of the lateral edges of the prothorax by serra- tures or nodular thickenings, and the various forms assumed afford ex- cellent subsidiary criteria for the definition of genera. Another pecu- liarity is the narrow and feeble dehiscence of the elytra at or very near the apex, there being but few genera, such as Diploarhis and Lobcrus, in which this character virtually disappears. The eyes are rounded and convex, usually rather well developed and coarsely faceted, but somewhat variably so. The antennce are always 11-

jointed, with a loose club which is generally 3-jointed, but sometimes purely 2 -jointed, and, in one case — Anchor ins — 4-jointed, a character remindful of Tritomidre. The anterior coxal cavities are generally widely open behind, but are completely and rather broadly closed in Diplocti'liis, completely but less broadly in Cryptopliiliis, narrowly but almost completely in Haploloplius, and about half closed in Scfaria, proving that no useful generalization in the definition of the family can be drawn from the form of the cavities. The Biphyllini, as stated by Reitter, are evidently a perfectly natural part of the present family, this being proved by general organization, tarsal structure and espe- cially by the radiating straight lines of the first ventral segment, also occurring in Cryptopliiliis, and, in an arcuate form, in To/nari/s.-^ The tribe is quite out of place in the Tritomidce, to which it was assigned by LeConte and Horn.

The Cryptophagidce comprise two distinct subfamilies as shown by the following characters : — j

AntennK inserted under the acutely margined sides of the front and remotely sepa- rated at base, the palpi mutually dissimilar, the maxillary elongate and slender, with the fourth joint elongate and more or less acuminate toward the tip, the labial short, with the last joint enlarged, oval to securiform ; pronotum generally bifoveolate at base Cryptophagin.-e

Antennas inserted on the front and more or less approximate at base, the palpi mutu- ally similar, short, stout and acuminate, the last joint of both small, narrow and subuliform ; trochanters always narrow and elongate, bearing the femora dis- tally ; pronotum never bifoveolate at base, though generally impressed ; anterior coxal cavities always widely open behind, the tarsi invariably simple and fili- form ; eyes always basal, the first abdominal segment never having radiating lines Atomarun.e

In tarsal structure these two subfamilies are linked together by way of the Cryptophagini anti Ceenoscelini. The insertion of the antennae in Aufhorophagiis seems to suggest also a slight drift toward the Atoma- riince, but this is very feeble and more apparent than real. In the mode of antennal insertion, and especially in palpal structure, the two subfamilies are radically distinct ; perhaps species may be discovered showing intermediate characters, but it is more probable that these bonds have long ago become extinct.

* These lines also occur in the subfamily Silvanini"e of the Cucujidas. |Names to which an asterisk is affixed apply to tribes or genera which do not occur within the limits of the American fauna as far as discovered.

The tribe Setariini is erected for three isolated European genera Sefaria, Haplolophus and Leucohimafiiim, and there is no American re])- resentative known thus far. The European genus CrxptophUus also necessitates the creation of a distinct tribe. All the other tribes are common to the two hemispheres.

BiPHVLLINI.

This is a small tribe, comprising a relatively large number of generic types. The body is oblong-oval or elongate-oval and generally no- tably depressed, pubescent and with the abdominal sutures very fine. The tarsi are pentamerous in both sexes, with the fourth joint small and simple, the fifth generally much elongated and the subbasal thicker and lobed beneath. The pronotum generally has some ele- vated longitudinal lines at least toward the ^sides ; the scutellum is short and transverse and the antennae rather short, with well developed club, very widely separated at base and inserted under the sides of the front, the basal joint moderate or small in size. The last joint of the maxillary palpi is slender, that of the labial large and securiform. The truncate posterior edge of the prosternum passes freely over the surface of the mesosternum, and the first ventral segment has two straight cariniie diverging from the middle of the base and extending to the apical margin or very nearly. The posterior sutures are flexed back- ward at the sides to a greater or less degree. The genera before me may be defined as follows : —

Last joint of the labial palpi broadly oboval, thick and convex, with the apex broadly truncate and excavated ; antennal club broad, oval, rather compact and 4-jointed, the eighth joint, however, very small, transverse and obtrapezoidal ; pronotum longitudinally lineate throughout its width Anchorius

Antennal club 2-jointed, the eighth and ninth joints small and perfectly similar to the seventh, the tenth abruptly large, rectilinearly obconic in form and somewhat wider and longer than the eleventh, which is transversely suboval and obtusely pointed *Biphyllus

Anchorius, gen. nov.

In this genus the body is oblong-oval, rather depressed, the upper surface feebly and evenly convex. The legs are very much stouter than in Diploca-hts, the femora broadly oval and the antennte still shorter. The minute dense punctulation of the under surface is devoid of larger punctures, which is not the case in either Diploavhis or Bi- phyllits. There is but one species before me at present, which may be described as follows : —

Uniform dark brown throughout the upper surface, densely dull and devoid of lustre, extremely minutely and densely punctulate and minutely, densely pubescent ; an- tenna? as long as the width of the head, the eyes large, convex and very coarsely faceted ; prothorax twice as wide as long, with the sides moderately convergent from base to apex, evenly and distinctly arcuate, the apex broadly sinuate, with the angles bluntly rounded ; basal angles obtuse but not obviously rounded ; sur- face with ten fine and entire subelevated longitudinal lines, those toward the sides rather more widely spaced and somewhat more strongly elevated, the intervals feebly concave and with scattered coarser punctures ; elytra one-half longer than wide, three times as long as the prothorax but not at all wider, the sides feebly arcuate, not continuous in curvature with those ot the pronotum, evenly, rather strongly rounded behind ; stride composed of unimpressed series of fine punctures, the intervals feebly elevated along the middle, the crest having a single series of short coarse and somewhat paler hairs, similar to those along the crests of the

* I follow DuVal in writing and adopting Biphyllus Stephens, instead of the emen- dation Diphylliis Redt. Lacordaire writes Dipliyllus, with the statement that Biphyllus is inconsistent with the laws of etymology. This would be perfectly correct if generic words were subject to the laws of etymology — but they are not. They are simply pronounceable, and, first of all, constant, combinations of letters having latiniform endings. They cannot, when once established, be changed under any circumstances. They are not supposed to have a meaning — that is as an essential quality. Specific names, on the contrary, always have a meaning, and are therefore subject to the rules of etymology.

lineatus, sp. nov. In the type, the fourth ventral segment has a small and very shal- low, transversely oval erosion at the middle and near the hind margin, the tifth much longer than the fourth, unmodified on the disk, and and very evenly rounded behind. This species is allied to the Cuban Diplociclus cosftilaUts but differs in its larger size and in having ten, and not eight, longitudinal pronotal lines ; it also seems to difler from the mns of Reitter, in the latter character.

Diplocoelus Giicr. The species are few in number and are widely isolated structurally among themselves, in fact constituting several subgenera ; they may be outlined as follows : —

Prothorax parallel or feebly narrowing from base to apex, broadly, evenly convex, the basal angles not prominent but not at all rounded, the surface with three longitu- dinal elevated liaes at each side, of which the inner is feeble and incomplete ; eyes moderately coarsely faceted; elytra with very feebly impressed series of close- set punctures, the intervals each with a series of suberect hairs, which are short and incon.spicuous,— becoming subobsolete in the European hiimenmts— brown or blackish in color, elongate-oval, feebly convex, feebly shining, minutely, closely punctured and densely pubescent, with coarse punctures interspersed on the p'onotum, sterna and near tlie sides of the abdomen.

Telmatophilini.

In this tribe the body is elongate-oval and convex, with slender an- tenna, moderate in length and having a narrow loose 3-jointed club, with the ninth joint notably smaller than the tenth in Tclmatophihts and Loberus, and subequal to the latter in Tomanis. The basal seg- ment of the abdomen is only moderately elongate, and the elytral suture is margined. The pronotum has two small deep and widel)' separated isolated fovece at the basal margin. The abdominal segments are perfectly mobile as in Cryptophagini, and the fourth tarsal joint is very small. The three genera differ considerably among themselves in general habitus and may be defined as follows : —

Elytra not margined at base, feebly margined along the suture, the surface pubescent and closely and irregularly punctured ; prosternal process acute at tip ; eyes well developed and coarsely faceted ; tarsi thick and strongly lobed and pubescent beneath, the basal joint of the posterior not much longer than the second, the claws thick and strongly arcuate but not obviously dentate ; abdominal sutures flexed abruptly backward at the extreme sides, the first segment as long as the next two combined or longer ; pronotum having a very fine excavated line along

No representative has as yet been discovered in the Pacific coast fauna, but the tribe is much better developed in America than in Europe. Crxptophilus, which is placed near Telmatophilus by Reitter, is entirely out of place, the completely closed anterior coxal cavities betraying a greater affinity with Diploca-lus.

Telmatophilus Hccr. This genus is widely extended in range through all the palasarctic and nearctic provinces, but has not yet occurred on the Pacific coast of America. We have but one species, as follows : —

Piceous-black, ratlier shining, densely and deeply but finely puncUn-ed throughout above and beneath, the pubescence short, ashy, the elytra in addition with im- perfect single series of slightly longer hairs ; antennfe and legs rufous, the former scarcely as long as the head and prothorax ; eyes convex and prominent ; pro- thorax barely two-fifths wider than long, the sides parallel, evenly arcuate, the edges finely serrulate and single ; apex broadly arcuate and as wide as the base, which is broadly bisinuate ; basal angles acute, the apical obtusely rounded ; disk feebly convex, finely and very densely punctate ; elytra but little wider than the i)roth(irax in the male, and less than three times as long, relatively larger in the female, obtusely rounded at tip, the humeri not exi:iosed at base ; punctures not coarser and much less dense than those of the pronotum ; legs stout. Length 2.4-2.7 mm. ; width 0.9-1.0 mm. Canada, Massachusetts, New York, Iowa and Colorado (Greeley) americanus Lee.

The male is a little shorter and stouter than the female and has a deep oval pit at the apex of the fifth ventral segment, and the hind tibice strongly dentate externally near the base ; the mesosternuni is very feebly concave between the coxas. The European caricis, which resembles a/iwrica/uis very closely, has a very feeble impression at the middle of the fifth ventral of the male, and the hind tibiie of that sex are much more feebly and obtusely swollen externally near the base.

Loberus Lrc. This genus appears to be exclusively American and will prove to be tolerably rich in species. The resemblance to certain crepidoderid Chrysomelidte has l)een alluded to by LeConte and Horn, and is suf- ficiently striking, the body is however narrower than in the great ma- jority of Crepidodera^. The broad and shallow transverse depression extends between the pronotal foveas but is semi -independent of them. The species before me may be defined as follows : —

Basal depression of the pronotum broadly impressed and transverse, almost adjacent to the basal margin ; elytral margins very narrow and equal 2

Basal depression more deeply and acutely impressed and somewhat anteriorly arcu- ate, being more distant from the basal margin on the median line ; elytral margins more broadly reflexo-explanate at basal third 4

darker, extending slightly beyond the base of the prothorax, the latter very slightly narrower than the elytra in the male, more distinctly so in the female, nearly twice as wide as long, the sides parallel and feebly arcuate, abruptly sinuato-convergent near the base, the basal angles right and not blunt, the apical obtusely rounded, the base broadly bisinuate ; punctures sparse and rather coarse ; elytra fully three and one-half times as long as the prothorax, parallel and broadly arcuate at the sides, the apex rather narrowly rounded ; humeri somewhat exposed at base ; disk more or less impressed at the suture on the pos- terior declivity before the apex.

Tomarus Lee.

The body in this genus is smaller and relatively shorter than in Lobcnis, and has a markedly different general habitus. The lateral edges of the prothorax are very finely double, the outer edge more or less distinctly and unevenly undulated, the border flexed inward for a short distance at apex, and, at base, as far as the fovea;, where the margin becomes \ery fine along the basal lobe. There is a fine super- ciliary ridge as in Loberus, but the antennce differ in having the basal joint of the club about as large as the second. I have not noticed any distinctive sexual characters in the male. The three following are the only species known to me at present : —

A small specimen from North Carolina may possibly represent a distinct species or subspecies oi pulchellus ; it is smaller, more obtuse behind and somewhat differently colored. The strong basal margin of the elytra enclosing a series of foveje along its posterior edge, is a marked feature of this genus and it is this which causes the minute denticulation of the elytral humeri mentioned above.

Cryptophagini. This tribe differs from all those which precede primarily and very radically in the structure of the tarsi, which, instead of being shorter and stout, frequently lobed beneath, with the fourth joint very small and pentamerous in both sexes, are here more or less slender and fili- form, never lobed beneath, with the fourth joint similar to the preced- ing and pentamerous in the females and heteromerous in the males, as in the C^enoscelini of the next subfamily. From the Telmatophilini they differ besides, as a rule, in a coarser and denser sculpture and vestiture, stouter antenna;, with less loosely connected club and less coarsely faceted eyes than in TelmatopJiihis and Lobenis. The first segment of the abdomen is usually more elongate, being subequal to the next two combined, and never has diverging lines ; the sutures are straight throughout the width, differing in this respect from Ccrnosce/is. The genera are rather numerous, those before me being readily recog- nizable by the following characters : —

Eyes ante-basal, small, rather finely faceted and not prominent ; frontal margin deeply emarginate and impressed at the middle, especially in the male, the front not at all prolonged beyond the antennre, the basal joint of the latter large and glob- ular, the second similar to the third and following, the club rather feebly de-

The definition oi Eiiiphyliis is taken from the Europern glabei-, and, as I have not seen the American representative — americamis Lee, of the catalogue, — the genus will not be further dwelt upon ; its affinity with AntJieropliagiis is much more pronounced than with Cryptopliagits, and the sinuation of the thoracic apex — due to the prominence of the apical angles — which has been hitherto advanced as a differential character, is one of the least important.

by far the largest species, HaploIopJms being the only other which ap- proaches it in this respect. The emargination of the clypeus, very deep in the male but feeble in the female, is apparently a unique char- acter in the family, and the antennae are peculiarly thick and compact in the male, though bearing some resemblance to those of Eiuphylus ; the female antenn;i3 are much shorter, more slender and with relatively larger club. The eyes are almost without parallel in the family in their position upon the side of the head and in their relatively slight convexity, the convexity and prominence of these organs being one of the most characteristic features of the family. The body is oblong, rather convex, very finely, densely punctate and clothed, often densely, with very short subappressed pubescence. The elytra in some of the paler forms clearly show the regular series of areolae on their under surface, shining through the diaphanous chitin and perhaps of signifi- cance in indicating that the family may be derived from seriately punctate archetypes ; at present these series of areolae are not con- nected in any way with the punctuation of the surface, which is alto- gether irregular, but there are frequently very feebly impressed super- ficial lines which appear on the exposed surface above them. The species are few in number and those in my cabinet may be thus char- acterized : —

Body large, more liroadly oblong, densely clothed with pubescence which nearly con- ceals the surface, the eyes smaller, the mandibles more prominent ; tibia- rapidly enlarged from base to apex ; basal angles ot the prothorax more or less obtuse... 2

Body smaller, the sides of the protliorax parallel and straight, the basal angles right and not at all blunt; body smaller, the eyes moderately large, rather more convex and less finely faceted, the mandibles smaller and less prominent, the pubescence quite sparse, not at all concealing the surface ; tibiae but feebly enlarged from base to apex ^

Si/fi/ralis of Miiklin, I have not seen.

Crosimus, gen. nov. In the general structure of the body this genus is allied to Salebius, and especially in possessing three lateral projections at each side of the prothorax, and in the same positions, but here the nodes are not thickened and take the form of broadly rounded and rather feeble un- dulations of the edge, the salients being spiculato-serrulate. It differs greatly from Salebius or Cryptophagus in the short stout, very convex and oval form of the body, long hirsute sparse vestiture, in having the elytral punctures arranged in uneven unimpressed double series, in having a fine raised line near each side of the pronotum extending from base to apex, and in the more longitudinally convex prosternum, the process being elevated far above the coxfe from an under view, the process more strongly margined at the sides ; the antenna, oral organs and legs are throughout as in Cryptophagiis. The basal fovea of the pronotum are connected by a very deep channel along the basal mar- gin, which is never interrupted at the middle by a carina, and the callous discal spots of Cryptophagiis appear to be obsolete. The tarsi are very slender and as long as in Salebius. The eyes are unusually small, absolutely basal and extremely convex, not very coarsely faceted. The two species before me may be described as follows : —

Body more narrowly oval, polished, black, the legs and antenna testaceous, the elytra bright rufous, black at the apex, at the middle of the flanks and transversely be- hind the base near the suture ; pube.scence moderately long and sparse ; prothorax

hirtus, sp. nov.

These species are mutually very closely allied but appear to be dis- tinct. The genus is probably confined to the Atlantic regions of the

continent.

Salebius, gen. nov.

This genus, with Crosi/iius, is distinguished from CryptoJ^/uii^'iis by having three subequal obtusely dentiform nodal points along each side of the prothorax —at the apex and near apical and basal fourth of the length, instead of a single nodal point, with a submedian spicule as in that genus. The node at the apical angles in Sa/el>ii/s is merely thickened, convex and more or less pubescent, Init the two posterior often have a deep puncture at the middle of the summit analogous to the central puncture of the flattened apical node so prevalent in Cryp- tophagiis. The tarsi are long anti slender and nearly all the other anatomical structures are similar to those of Cryptopliagiis, except that only the anterior two of the pronotal callous spots are visible, and the impression along the basal margin is feebler, with the median carina always distinct. The five species in my cabinet may be recognized as follows : —

Punctures very fine but deep as usual, those of the pronotum very dense ; body dark piceous, blackish beneath, the antenna? and legs castaneous ; pubescence short, even, decumbent and rather abundant, more distinct on the pronotum along the sides and median line ; prothorax parallel and slightly rounded at the sides, not more than one-half wider than long; elytra two-thirds longer than wide, only slightly wider than the prothorax and fully three times as long, the punctures fine and rather close-set; hind tarsi nearly as long as the tibiae ( J )• Length 2.4 mm.; width 0.9 mm.

Cryptophagus Hbsf. This is a large genus, including some of the larger and more con- spicuous species of the family ; they are easily separable among them- selves but rather difficult to classify in a satisfactory manner. The body is ol)long-oval, convex, strongly punctured and always coarsely, distinctly, though not densely, pul)escent, the elytra having in addition some longer hairs, which are frequently very conspicuous and always subserial in arrangement, although the punctuation may, and usually does, exhibit no trace of series. The antenna; are moderate in length, thick, with the club abrupt, parallel and loosely 3-jointed. The prothorax is wider than long, subparallel anteriorly and narrowed toward base from about the middle, where there is a more or less dis- tinct acute and reflexed marginal tooth, and the apical angles are thickened and obliquely truncate, the oval truncature sublateral, pol- ished, generally flat or rarely concave and foveate at the middle ; the lateral edges between the submedian denticle and the well-defined and sometimes subprominent basal angles is generally obsoletely serrulate ; the disk is deeply, though finely, bifoveate at the base, the fovete connected by a fine groove following the basal margin and often sub- interrupted at the middle by a fine longitudinal carina. There are also quite generally visible two small impunctate and feebly callus-like spots at each side near lateral third. The maxillary palpi are well developed, the last joint elongate and gradually, somewhat obliquely and obtusely acuminate, the last joint of the labial moderately stout, oval and truncate at tip, the mentum large, transverse, the basal parts concave and punctured and separated from the deflexed apical parts by a strong, transversely arcuate carina, which is prolonged anteriorly on the median line to the extreme apex. The anterior coxte are obliquely oval, rather large and deep-set, and the intercoxal process is prolonged posteriorly, with its free tip ogivally acuminate and dor- sally margined. The mesosternum is broadly and feebly concave. The tarsi are slender, and the abdominal segments two to four decrease gradually in length, the first longer, generally exceeding the next two combined, the fifth about as long as the second and rounded in both

The elytra have sometimes-as in plemis—^. smooth callous discal spot near the apex of each, which may be homologous with the smooth polished mirror-like sexual spots of the melynd genus Eurelxmis. Sexual differences in the form of the body are occasion- ally very pronounced, the male being shorter and stouter than the female, with relatively broader prothorax and shorter elytra.

Henoticus T/io/ns. The general structure of the body, prosternum, legs and tarsi, trophi and antennae are here almost precisely as in CrypiopJiagits, but the con- verging sides of the front above the antennns are finely reflexo-margi- nate, and the structure of the sides of the prothorax wholly different, there being no trace of thickened nodal point, apical or otherwise ; the edge is regularly spiculato -serrulate throughout, except for a short distance near the basal angles ; it also differs in having the fine sub- sutural line entire or subentire. The deep groove near the basal mar- gin of the pronotum connecting the conspicuous basal fovese is similar to that of Crosiinus and without trace of medial interrupting carina. The elytral punctures are arranged wholly without order, the pubes- cence short and the pronotum without trace of callous spots. The species known thus far are two in number, and are both very abun- dant in individuals ; they may be outlined as follows : —

Black or blackish in color throughout when mature, the legs and antennae paler, pol- ished, oblong, convex and moderately stout in form, the pubescence short, very- sparse, even and reclined ; eyes vi'ell developed though scarcely half as long as the head ; prothorax moderately transverse, the sides very nearly parallel, broadly and evenly arcuate, the serratures even and moderately developed, some eight to ten in number ; punctures not coarse but deep, moderately close-set, the sur- face rather convex ; elytra oblong, distinctly wider than the prothorax and three times as long or a little less, obtusely rounded behind, the punctures coarse and decidedly sparse.

Pteryngium Reitt. Among the close allies of Cryptophagiis, the two species of this genus may be instantly recognized by the rather narrow, strongly de- pressed and planulate body, with parallel sides, finely, densely punc- tured surface, short pubescence and entire subsutural lines. In this last feature, as well as the evenly arcuate and minutely, evenly serru- late sides of the prothorax, they resemble Henoticus, but differ in the depressed body and in the very minute basal fove;^ of the pronotum, connected by a very fine and feeble basal groove, which is finely inter- rupted at the middle. In the structure of the legs, prosternum, trophi and antennce they perfectly resemble Cryptopluii^us, but differ from that genus, as well as Henoticus, in the somewhat shorter and thicker tarsi, and especially in the much more elongate basal segment of the abdomen, this being as long as the next three combined ; the sutures are free and perfectly straight throughout, as usual in the tribe. The frontal margin above the antennce is very obsoletely and indis- tinctly margined. The species may be thus characterized : —

Body parallel, depressed, rather feebly shining, pale rufo-ferruginous throughout, the pubescence short, even, subdecumbent and rather abundant ; eyes moderate in size and prominence, not very coarsely faceted, the antennas scarcely as long as the head and prothorax, notably stout, the club parallel and broad, its first two joints equal and very strongly transverse, joints one to three rapidly decreasing in size ; prothorax about one-half wider than long, the sides parallel, evenly, distinctly arcuate from base to apex and minutely, evenly serrulate, the apex broadly arcuate, the punctures fine but deep and very close-set ; elytra but little more than one-half longer tlian wide, about equal in width to the prothorax and two and one-half times as long, parallel, obtusely rounded behind, finely but deeply, very closely punctate.

Atomariin.e.

The genera of this subfamily may be readily recognized by the palpal structui^e and position of the antennce, these organs being inserted upon the front and more or less approximate at base, the fovese being either small and exposed or deep cavities, separated above by a short an-ular extension of the upper surface, and particularly developed m clwscelis and Stcrnodea. The tarsi are always slender and filiform, as in the Crvptophagini, of the preceding subfamily, and. as m that case there is frequently a feeble thickening of the anterior in the males The body is much smaller as a rule than in the Cryptopha- ciriK and may be either narrow and parallel, as in Agathengis, or oval and more convex, as in the great majority of genera. The subfamily may be resolved into the four following rather widely differentiated

The Sternodeini are peculiar to the pala^arctic provinces, but the other tribes are well represented in America, the Ephistemini, however, by no means so extensively as in Europe.

C.tNOSCELINI.

This tribe is composed at present of the single genus Cccnoscelis, which is very well developed in the northern parts of America, and, to a less degree, apparently, in the pah^earctic region ; its species are the largest and most conspicuous of the subfamily, and compare very closely in this respect with CryptopJiagus, but the body is narrower and more elongate as a rule.

Casnoscelis T/io/ns.

This is one of the best defined and more isolated genera of the family, distinguished by the elongate, strongly punctured and pubescent body, with double lateral margin and broadly impressed basal parts of the pronotum, convex, coarsely faceted and sparsely setulose eyes and well developed stout antennce, with the basal joint unusually large and ob- conical, the second and third diminishing in size and four to eight still narrower and alternately shorter and longer, as usual in the Ato- mariinai ; the basal joint of the club is small, the last two well devel- oped. The tarsi are very slender and the posterior are 5 -jointed in the female and 4-jointed in the male, there being otherwise but lit- tle sexual disparity; the male is usually rather narrower, with relatively larger, and occasionally somewhat less transverse, j)rothorax. Thepros- ternal process is narrower, the tip prolonged, free, concave toward tip and acurninate, the mesosternum being appreciably concave. The abdominal sutures differ greatly from the usual type and are strongly reflexed for a short distance at the sides, especially posteriorly. The American species appear to be far more numerous than the European as described thus far, and those before me may be outlined as fol- lows : —

Atomakiini. The Atomariini constitute by far the larger part of the subfamily, and comprise several genera in America. The body is much smaller throughout than in the preceding tribe and seldom or never surpasses 2 mm. in length. The genera before me may be briefly defined as follows : —

Elytra not margined at base ; body always pubescent, the antenna; separated at base by a third of the width of tlie head or less 2

Elytra marghied at base ; antennne separated at base by nearly half the entire width of the head, though purely frontal as usual ; body minute in size and virtually glab- rous 3

2 — Body elongate and parallel in form, less convex, the prothorax angulate and foveate at the lateral edges far behind the middle ; antennre very approximate at base, with the basal joint obconical and feebly arcuate ; first ventral segment behind the coxce not as long as the next two combined ; prosternal process narrow.

Agathengis

Body oval, more convex, the prothorax rounded or angulate at or before the middle, and generally having the minute fovea, in the edge at the point of angulation, less developed than in Agatheugis ; antenna less approximate at base, the basal joint shorter and oblong ; first ventral segment behind the coxa; as long as the next two, the posterior segments shorter ; prosternal process generally narrow and not prominent but becoming broader and more prominent in certain aberrent European forms, such as cephcnnioides Atomaria

3 — Body oblong-oval, strongly convex, the prothorax rounded at the sides from above and not angulate, the edge minutely beaded and not foveate ; first ventral as long as the next three combined, with a short feeble plate behind the inner part of the coxpe, becoming obsolete externally and gradually confounded with the coxal margin, the posterior segments short ; prosternal process very wide, with acute lateral edges not attaining the apical margin, nearly as in Ephiste»i!{s...TlSSiCt\a.

The last of these genera is evidently a transition toward the Ephiste- mini in some respects, but the sciitellum is broadly oval as in the others, the body more loosely connected and the prosternal process evidently free and broadly, arcuately obtuse at tip. The basal margin of the elytra will isolate it at once from any other member of the sub- family known to me, causing it to bear somewhat the same relation- ship to the others, in that respect, as Toinanis, does in the Cryp- tophaginae.

This aggregate of species, usually treated as a subgenus of ^Av//(?;7'rr, satisfies the ordinary definition of a genus in having several constant

and purely characteristic structural characters, and is therefore valid. It differs from Atomaria in the characters stated in the table, and the habital differences are such that it is seldom a matter of doubt as to the proper genus at the first glance. The body is elongate, generally quite slender and subparallel, convex and subuniformly, sparsely clothed with short and subdecumbent hairs, which become gradually still shorter in a sutural region near the elytral apex. The antennce and eves are moderately developed, the former generally rather stout, with more pronounced club than in Afomarm, and the joints of the shaft also very conspicuously alternating in length ; the eyes are never very prominent and are not very coarsely faceted. The species are numerous in North America, relatively more so, apparently, than in Europe, where thev are greatly outnumbered by Ahvnarm. Although easily separable by sight as a rule, they are even more homogeneous in adherence to a fixed type form than mAfomaria, and consequently form a difficult study for the taxonomist, as the differences are nearly all comparative. They seem to be quite local in distribution, judging from the material at hand excepting crassula which is common to the Atlantic and Rocky Mountain regions, and therefore fall very satis- factorily into primary geographic subdivisions as follows: —

forma

Oc-/uvnife;is quite strongly resembles sfric-fu-o/Z/s, but differs in the more slender form of the body and in the very much more minute and sparse punctuation. The species described under the name /^ar- vicoUis is represented by a unique, as is also the form with senately punctured elytra which I have surmised to be its male ; more material is necessary to decide this rather puzzling point, as the difference m elytral sculpture is certainly very marked. I have, however, noticed at times a slight sexual difference in density and arrangement of punc- tures elsewhere in the family. FuscicoUis of Mannerheim, and plamdata of Maklin, I have not seen, the latter is described as oblong, de- pressed, fusco-testaceous, finely and densely punctate with the legs and elytra rufo-testaceous.

Atomaria Stepli. The species of this genus are less numerous in America than Aga- thengis, and for the most part present a rather monotonous appearance. The^'body is generally oblong-oval and convex, shining and sparsely clothed with short subdecumbent hairs. The antennae are usually slender, moderate in length, with the basal joint short and oblong or more developed internally toward base than externally ; the joints

of the funicle are alternately shorter and longer as usual in the tribe, but they are somewhat more widely separated at base than in Ai^atlicn- <:;is ; the first two joints of the club are generally about as long as wide or longer, and seldom at all transverse. The eyes are larger and more coarsely faceted as a rule than in Ai::;at]ieiigis. The prothorax is narrowed anteriorly and generally more or less distinctly angulate at the middle — not nearer the base as in Ai^^af/iengis — and the marginal fovea at the point of angulation is not so marked a character as it is in that genus ; the edge is finely beaded and frequently feebly crenu- late from the angulation to the base ; the disk is evenly convex, be- coming broadly concave along the very finely margined or simple transverse base. The prosternal process is narrow, but in certain species, such as the European tiirgida and cepheuiiioides, becomes wider, more prominent and more strongly margined along the sides — a divergence in the direction of the remarkable genus Sfcnwdca. There seem to be, in fact, several cjuite well defined subgenera among the species of the European fauna having for types such forms as turgidcu with medially lobed thoracic base, stout antennre and broader and more i)rominent ijrosternal process, ceplienuioidcs, with large and broadly truncate prothorax, broad prosternal process, stout antennas and very small eyes, and uitifasciata, which is perfectly con- generic with our species and might be regarded as Afomaria proper.

The elytra are finely, irregularly punctured, frequently subinflated before the middle, truncate at base and slightly impressed within the humeral callus. The abdominal sutures are straight, the first seg- ment as long as the next two combined and the fourth shorter than the second or third. The legs and tarsi are slender.

The species in the neighborhood of ochracea form a very difificult study, aiid my treatment of them above must be regarded as pro- visional. Fallax bears some resemblance to nanula, but the antennce are more approximate in insertion upon the front, being separated by a third of the total width in the latter. Katntschatica Mots., is quoted by Mannerheim as occurring in Alaska, but I hav not seen it ; it is ovate, black, with the elytral humeri and apex testaceous and the prothorax arcuately dilated at the middle. The species lepidula of Miiklin, from Sitka, is also unknown to me ; it is described as oval, slightly convex, shining, testaceous, with the prothorax slightly rounded at the sides and deeply, the elytra finely, punctate, and the antennoe not approximate at base ; it must be an unusually large

species, as its length is given " i line," and it is said to be extremely rare.

Tisactia, gen. nov. Although bearing a certain general resemblance to Afoinan'a, this genus is really profoundly different in several structural characters, and it may be readily recognized by the marginal bead at the base of the elytra ; it also differs in having the pronotum perfectly even and unimpressed at l)ase, in its widely separated frontal antennre and in its broad prosternal process, margined at each side by an acute carini- form edge. The head is rather deeply inserted, the eyes well de- veloped and rather coarsely faceted but not very convex, and the cly- peus, which is slightly prolonged and expanded before the antennae, is separated from the front by an impressed straight suture extending between theantennal foveas. The antenm^ are nearly as in Afomaria, the first joint relatively still smaller but subsimilar in form, and the club parallel, loosely 3-jointed and well developed. The legs and tarsi are slender, the latter filiform, moderately short and pentamerous, the mesosternum moderately wide and unimpressed between the cox;Te, and the deep -set anterior cox;^ are oblique and much more transverse than in Atoinaria approaching Ephistemus in this respect, the cavities sharply angulate externally. The scutellum is moderate in size and transversely oval. The single species is the following : —

Body oblong-oval, very convex, black or blackish, the legs and antenna; paler, testa- ceous, the club of the latter blackish, apparently glabrous, each puncture, how- ever, with an excessively minute hair ; punctures throughout very fine and sparse, not denser on the prothorax, which is moderately transverse, very convex and deep on the flanks, the base distinctly wider than the apex, transverse, finely beaded and feebly lobed at the scutellum ; sides broadly arcuate from above, the lateral edges finely but acutely reflexo-beaded and nearly straight from a sublat- eral viewpoint ; elytra slightly longer than wide, ogival at tip, widest and dis- tinctly wider than the prothorax slightly before the middle, the base equal to the base of the latter, the humeri not at all exposed at base, the sides arcuate, the suture not margined, minutely dehiscent at apex as usual.

Ephistemini.

This is one of the more highly specialized tribes of the family, composed of very minute, broadly oval and convex glabrous species, feebly represented in the nearctic, but moderately abundant in the

pal?earctic provinces. It is distinguished from the other tribes of the Atomariinse, excepting the Sternodeini, by the structure of the pro- and mesosterna, and in the close juncture of the prothorax with the hind body, and, in the extremely specialized Ephislcnius, also by a form of anterior coxa, antennal club, antennal clefts of the proster- num and form of scutellum which are wholly foreign to the rest of the family. The post-coxal plates of the first ventral segment, though feebly developed, should also be alluded to as an important distinguishing character. In the general structure of the body, legs, palpi and tarsi it is however a perfectly normal member of the sub- family Atomariinai. The elytra are never margined at base, the pro- notum is always unimpressed, and the deeply seated anterior coxne are transverse and subcylindrical and attached near the sides of the body, the cavities acutely angulate externally. The species before me may be assigned to the two following widely differentiated genera : —

Antennoe free, the club more slender and bilaterally symmetric, the grooves before the eyes and prosternal clefts wholly obsolete ; scutellum transversely oval as in Atomariini ; prothorax more transversely truncate at base, feebly arcuate at the middle *CureIius

Antennae partially received in repose within narrow deep grooves before the eyes and in a broad shallow cleft and excavation between the prosternum and hypomera, the club rather more developed, parallel, loose and asymmetric, the joints being more developed on the inner side ; scutellum still more minute, cordate, pointed behind and as long as wide or longer ; prothorax broadly angulate at base.

Ephistemus

These genera are related to the Atomariini through the singularly synthetic genus Tisaciia described above, which has the unimpressed pronotum, broad, flat and laterally margined prosternal process, an- tennal insertion and sensible, though somewhat differently formed, post-coxal plates of the Ephistemini, the loosely connected body and prothorax and free prosternal process of the Atomariini, and a strongly margined elytral base, which very exceptional character is foreign to both but existent to a well-developed degree in Tonianis of the Cryp-

tophaginae.

Curelius, gen. nov.

This genus is founded upon the Ephistemus dilutus of Reitter, and exiguus of Erichson, and, as far as known to me, is exclusively European. Although abundantly distinct from Ephistemus, it does not seem to have been recognized thus far by Reitter and other European authors.

128 Journal New York Entomological Society. [Voi. viii.

Ephistemus Stcph. In this genus, as in the preceding, the body is evenly oval and rather pointed behind, the sides of the elytra and prothorax being perfectly continuous and without a reentrant angle at the contiguous bases. The surface is virtually glabrous, having only a few extremely minute hairs visible under high amplification, and is feebly and sparsely sculptured. r)ur single representative is the following : —

Oval, convex, polished, black or piceous-black the elytra gradually rufo-testaceous posteriorly almost in apical half, the legs and antennae paler ; surface impunctate ; prothorax moderately transverse, the sides convergent and rather strongly, almost evenly arcuate ; elytra rather less than three times as long as the prothorax and about a third to nearly half wider, widest at two-fifths, the sides strongly, almost evenly arcuate, converging behind, the tip narrowly rounded.

Mycetophacud.'E Auct. It matters but little what name is used to designate a genus, and consequently perhaps, a family, provided it be the oldest properly published name, and that there be unanimity of opinion in regard to the points at issue. The Geoffroyian name Trifoi/m has been adopted in the most complete European catalogue, presumably after proper investigation, for the familiar Afyccfopliagus, and, as arbitrary dissent from this decision would only tend to perpetuate ambiguity in the fundaments of nomenclature, I am ready to take any course which

* The following is a new species from the European fauna, recently received from Mr, Reitter :

Narrowly oval, polished, blackish throughout, the elytra obscurely rufescent,blackish toward base, the legs and antennae pale, extremely minutely, feebly and sparsely punctate; prothorax rather short and strongly transverse, the sides converging and arcuate as usual ; elytra relatively long, rather more than three times as long as the.prothorax but only about a fourth to a third wider, subinflated be- tween a third and two-fifths from the base and narrowly rounded at tip.

may tend to bring about permanent agreement, assuming that it is never too late to correct a mistake, however repugnant it may be to our spirit of conservatism. The name Triplax is therefore to be re- established in the Erotylidce.

The present family is taken up for investigation at this time, primarily to draw attention to the inharmonious and composite scope which has been given to it hitherto by our systematists. Of the genera which have been included within its limits by LeConte and Horn, Diploccelus 2a\A BipJiylliis are assigned by Heyden, Reitter and Wise to the Cryptophagidai, which disposition of them is eminently ap- propriate. Hypocopriis forms a subfamily of Cucujidee near the Mono- tomince, and is also to be removed.

Again, as an important fact because affecting both the European and American scope of the family, it should be stated that Bergi/n/s is in no wise allied to the Tritomidie, but belongs near Lyctiis, in fact only distinguishable from that genus by the obliquely truncate maxil- lary palpi.*

Finally, but by no means least, it is to be remarked that the Euro- pean Triphylhis does not occur in America, the species assigned by LeConte and Horn to that genus forming in reality two purely hetero- merous genera in the vicinity of the malandryid Tefrafonia. The Tetratomini are distinguished from other Malandryida^ by the 3- or 4- jointed antennal club, and will be alluded to in more detail near the close of the present paper.

The present family is evidently closely related to the Trixagidfe

* The following is an interesting new species of Berginus : — Very slender, convex, blackish, the under surface, legs and antennae paler; head and pronotum coarsely and closely punctured, the elytra with approximate series of similar coarse and close-set but well-defined punctures, each puncture throughout bearing a verj' small recurved squamiform hair ; prothorax as long as wide, slightly narrower than the elytra and a little wider than the head, the sides arcuate and parallel ; eyes small and prominent ; antennae slender, the two basal joints larger and the club 2-jointed ; under surface coarsely, sparsely punctured, except the last four segments of the abdomen which are finely and longitudinally strigato-punctate, the first segment as long as the next three combined; legs short, the femora stout, the tibiae and tarsi slender.

(Byturidte) and Dermestida?, and is (|uite out of position in the catalogue of Heyden, Reitter and Weise. Its general characters have been sufficiently presented by LeConte and Horn and need not be re- peated at the present time. The tarsi are filiform and 4-jointed and the anterior in at least the first subfamily, are 3 -jointed, more or less dilated and pubescent beneath in the males :'■> the basal joint is generally elongated. The anterior coxee are large, obliquely ovoidal and prominently convex in the first subfamily but smaller in the second, narrowly separated, with the cavities widely open or closed. The ornamentation of the elytra in many species is remindful of the Attagenini, but the eyes are coarsely faceted — in marked contrast to the Dermestidie. The Trixagidai are intermediate between the two families in this respect.

The Tritomidre of America consist of two subfamilies which differ greatly from each other in general habitus, and are sufficiently defined by the following characters : —

Anterior coxre large and convexo-prominent, the cavities widely open behind ; bases of the prothorax and el3'tra equal in width, the scutelluna well developed; sides of the prothorax defined by a thin acute edge ; hind coxje narrowly separated.

Tritomin.-e.

The latter of these is represented by a single isolated genus com- mon to Eurojie and America.

Tritomin.e. The body is oblong-oval, convex or moderately depressed and always clothed with coarse and sparse pubescence. The four American genera before me may be separated by the following primary characters : —

Basal angles broadly rounded ; body very minute 5

2 — Epipleurse horizontal and flat 3

Epipleurae concave and rapidly descending externally 4

3 — Eyes transverse, sinuate anteriorly Triloma

Thrimolus, gen. nov.

This genus is composed of a single exceedingly minute species, differing radically from those which precede in the broadly rounded basal angles of the prothorax. The body is oblong-oval, moderately convex, clothed rather sparsely with coarse and moderately long re- clined hairs, with other longer erect setae serially bristling from the elytral flanks. The head is large, transverse and well developed, the eyes moderately large, basal, not very jjrominent, somewhat trans- versely oval, entire and much less coarsely faceted than usual ; the clypeus is rather short and broad, with the suture transversely rec- tilinear, not impressed and very feeble. Antennae moderate in length, 1 1 -jointed, with a compactly cylindric stout and 3-jointed club, the joints six to eight gradually increasing in width and decreasing in length, the latter as wide as the base of the club. Prothorax broadly arcuate and very finely beaded at base. Scutellum well developed, broadly subtriangular or parabolic. A.nterior coxa; large, obliquely suboval, very convex and narrowly separated. Basal segment of the abdomen as long as the next two combined ; two to four relatively shorter than usual and gradually diminishing somewhat in length, the hind coxae very narrowly separated. Legs slender, coarsely, sparsely herissate with moderately long hairs, the tarsi extremely slender, fili- form, much shorter than the tibiae, with the basal joint but little longer than the second, normally 4-jointed throughout, the claws small and very slender ; tibial spurs small and much less developed than usual.

The antenucC are bilaterally symmetric, shorter and more compact than in Typhcea and the elytral punctures are altogether irregular in distribution. The type may be briefly defined as follows : —

Body dark luteo-testaceous in color throughout, the legs and antenna; still paler, the club of the latter very feebly infuscate, shining ; head and pronotum subimpunc- tate, the latter short and strongly transverse, more than twice as wide as long, the sides converging, broadly arcuate and subcontinuous with those of the elytra, the disk wholly devoid of basal fovea or impression ; elytra oblong-oval, rather con- vex, slightly longer than wide, broadly and obtusely rounded conjointly at tip, much wider than the prothorax and more than three times as long, the sides broadly arcuate ; punctures very fine, sparse and subasperate ; under surface shining, sparsely clothed with coarse inclined hairs.

MVRMECHIXENIN.E.

This subfemily is evidently assigned properly to the Tritomidte by LeConte and Horn, although the facies departs conspicuously by reason of the small prothorax and wide elytra, the latter rather si^arsely clothed with an even decumbent vestiture, finer and less con- spicuous than in Tritominx'. The single genus is as follows: —

Myrmechixenus Cliev.

Our single species occurs throughout the more southern parts of the United States, from the Atlantic to the Pacific, and may jjossibly be identical with some European form ; it may be briefly defined as follows : —

I'lody narrowly oI)long, convex, rather sliining tlioiigh finely, deeply and very closely punctured throughout, reddish- brown in color, the legs and antennas paler ; head subtriangular, the eyes well-developed, moderately convex, coarsely faceted as usual ; antenn;ie moderate, the club loosely 5-jointed, joints six to eight in- creasing gradually in width ; prothora< distinctly wider than the head, slightly transverse, widest near ajiical third, the sides parallel, rounded, the base and apex equal and feebly arcuate ; elytra between t^vo and three times as long as the prothorax and about two-lifihs wider, the humeri exposed at liase ; sides parallel and broadly arcuate, the apex obtusely rounded ; abdominal segments convex, gradually and but slightly decreasing in length, as usual in the Tritom- id;v, the last partly exposed dorsally. Length 1.7-I.Smm.; width 0.75-0.78 mm latridioides CrotcJi

This species does not appear to be very common ; the specimens in my cabinet are trom South Carolina, El Paso, Texas, and River- side, California, the latter sent to me by Mr. H. C. Fall. The basal joint of the hind tarsi is much elongated, as in normal members of the family, which is an additional reason for Ijelieving that it is cor- rectly placed in the Tritomidce.

DERMESTID-E.

The Dermestidx are a small family of clavicorn beetles, which, in their notably varied structural characters, seem to constitute one of the old synthetic types of Coleoptera, having some philogenetic relationship with both the Geodephaga and Serricornia. They have the anterior coxal cavities open behind, the tarsi simple and 5-jointed,

Jiineigoo.] CaSEY : On NoRTH AMERICAN COLEOPTERA. 13i^>

the claws unmodified, the sternal side pieces very wide and the hind coxae lamellate and transversely excavated. The antenna are ex- tremely varied in structure and may or may not be received within protecting pits or excavations, and the legs may be free or strongly retractile. In considering the depression for the protection of the antennae, a distinction should be drawn between a large and vaguely limited concavity of the hypomera — or inflexed side of the prothorax — as in Dermestes, and a closely circumscribed and sharply defined pit ; the former characterizes most of the genera in some form, and be- comes a true protective fossa in a few genera, but the latter only oc- curs in Anthfc/iiis.

The genus Trixagus (^Byfiinis I-at.), is evidently allied to the Dermestidae, but differs in so many radical characters, such as the closed anterior acetabula, lobed tarsi, dentate claws, narrow sternal side pieces and structure of the mesosternum, that the position as- signed it by Reitter as a distinct family is probably as satisfactory as any, and I have therefore not considered it in the following revision. As thus restricted, the American Dermestid;e may be assigned to five distinct tribes characterized as follows : —

Head without ocellus ; anterior coxte large, contiguous, the presternum not visible between them, the mesosternum between the coxae moderately wide, ogival and not sulcate ; antenna; ii-jointed, with a 3-jointed club, similar in the sexes and not received within sharply circumscribed pits ; hypomera concave anteriorly ; epipleuroe strongly defined, wide and inflexed toward base ; body clothed with short hairs Dermestini

5 — Anterior coxae contiguous at apex over the presternum, which has the form of a transverse pointed plate; antenna lljointed, the club 3-jointed, not received within al)ruptly excavated pits, the hypomera biconcave ; legs very closely retrac- tile ; body glabrous, the epipleura- distinct toward base ; scutellum well developed.

Ori'Hii.ini

Except the small and isolated tribe Trinodini, which is confined to tlie .A^tlantic and Sonoran regions, all of these groups are very general in distribution.

Dkrmkstini.

The genus Deniwsfcs differs so greatly from tlie other types of the family in the absence of the very characteristic vertexal ocellus and contiguous anterior coxre, that it is necessary to regard it as a distinct tribe. The metacoxal lamina is narrow, extending only to the para- pleura, and is notal)ly elongate internally, the XWivx. seriate with short stout si)inules and the tarsi rather stout, with the basal joint shorter than the second, generally very markedly so, but sometimes only slightly as in lardariiis.

Dermestes Linn.

The species of Dcimrsies are rather numerous and are the largest of the family. They can be readily classified by the form of the inner marginal suture of the abdomen toward base, and by the form and vestiture of the prothorax, as follows : —

Inner lateral suture of the first abdominal segment infiexed at base to the outer limit of the hind coxn:?, becoming deeply excavated at the basal margin 2

Inner lateral suture straight, not infiexed basally and distant at base from the outer limit of the coxae ; pronotum not deeply declivous latei^ally, the margin visible throughout from above 10

2 — Pronotum clothed densely throughout with variegated black and fulvous pubes- cence, except in incdialis, the flanks deeply declivous; male with the third and fourth segments foveolate at the middle 3

Pronotum clothed with dense cinerous pubescence laterally, leaving a large triangular or [jarabolic discal area sparsely clothed with almost uniform pubescence, the flanks rather deeply declivous 7

Pronotum somewhat sparsely or inconspicuously and quite uniformly pubescent throughout, the flanks less declivous, the lateral margin visible from above throughout the length ; third and fourth ventrals foveolate in the male 9

3 — Pronotum having, as a marked feature of the vestiture, three widely separated points of pale pubescence arranged transversely at about the middle of the length 4

angustus, sp. nov. Sobriniis of LeConte, I have been unable to identify amidst the material accessible to me. Rattiis and sign a/us are by no means varietal forms, but perfectly valid and very interesting species ; niannerheimi seems, however, to be a variety of the very widely dis- tributed caninus ; it is wholly different from marmflratiis, as I have previously pointed out (Bull. Bk. Ent. Soc). The identity of nmcoreus and carnivonis rests upon the authority of the Hanshaw List. Say described his nuhihis from Florida and Pennsylvania, and the characters given coincide entirely with those of caninus and not with the more pubescent form named nuhipennis above.

Attagemni.

This is the largest tribe of the family, and contains a considerable number of genera having the legs more or less free throughout. The laminate portion of the hind coxce extends about half way across the end of the parapleur?e ; the epipleurje are distinct and generally strongly defined toward base, and the prosternal process is visible, though generally narrow, between the coxoe, its free tip resting in an apical pit of the mesosternum which is frequently prolonged to the apex of the latter as a well-defined sulcus or fossa. The antennae are of varied structure, and the antennal fossa may be traced in successive stages of development through the genera in an instructive and inter- esting manner. In the first four or possibly five genera of the tribe,

144 Journal New York Entomological Society. [Voi. viii.

the hypomera are merely flat or concave, without trace of an enclosed antennal fossa, but in Trogodenna the fossa appears in one of its prim- itive stages, and may be conceived to be the result of retractility of the anterior femora. The crural fossc'e are deep and defined anteriorly by a strongly elevated acute cariniform line, extending obliijuely to the hind angles of the prothorax, and forming the posterior boundary of the hypomeral concavity. To suggest that this latter concavity has not been evolved primarily as a shelter for the antennae as in An- thremis, for example, it may be observed that it is equally large and well formed in both sexes, although the antennae differ sexually to a great degree, and it is only in the male that it is in any way com- pletely utilized or compactly filled by that organ ; in the female, where the antennae are comparatively very feebly developed, these organs lie in repose along the botton^ of the concavity, which is much too large to form a secure shelter. In Trogodenna the fossa occupies the entire length of the prothorax, but in Cryptorhopalian while hav- ing a general form which undoubtedly betrays a development from that of Trogodenna, it has become smaller and forms a secure shelter for the antennas, the.se having become similar in the sexes and assum- ing a form so radically different from those of Trogoderma that it is difficult to trace any philogenetic relationship, and in Tliaiiinatoglossa, the modification is carried still further, the two closely connected club-joints of Cryptorhopahtm becoming a single very large joint. Acolpiis appears to be a very satisfactory intermediate between the non-fossate genera and Trogoderma, and it is possible that more care- ful observation may there show the antennal fossa in a still more in- cipient stage of formation. The American genera may be defined as follows : —

Basal joint of the hind tarsi very short, much shorter than the second ; antenna! fossa not defined ; legs free, the hind femora retractile as usual 2

Basal joint elongate, generally but little shorter than the next two combined ; antenna' 1 1 -jointed in both sexes 3

If the metacoxal plates only attain the parapleurae in Acolpus, as stated by Jayne, this genus forms a remarkable exception to the entire tribe, and I strongly suspect that the author is mistaken. Neither this genus nor Tluuimatoglossa is represented before me at present, and I am therefore unable to consider them below. The species are all pubescent, generally with nubilous variation in density, usually elongate or oblong-oval in form and of less compact build than in the Anthrenini or Orphilini, but similar in this respect to the Dermestini and Trinodini.

This genus is comparatively local, occurring only in the Sonoran provinces, and is distinguishable at once from Attage/iiis by the structure of the antennal club and hyi)omera and the lo-jointed male antenna as vvell as by the complex vestiture.

Ferplcxa of Jayne, I have not seen, but it is evidently allied to hyturoides, differing in the relatively shorter last joint of the antennal club. Byfuroides was considered by Dr. Jayne as the female of horni, but this is not the case, as I have both male and female of that species as well as the allied uteana.

JVove/s/s differs from Lanoriis in antennal and hypomeral structure, and from Telopes in the structure and armature of the legs in addition.

Dearthrus Lee.

This genus is allied to Attay;enus but differs in having the meso- sternum completely divided by a narrow shallow sulcus, in the 9-jointed antennas and in the shorter, less inwardly postero-extended metacoxal lamina. The single species may be defined as follows from the male : —

Narrowly oblong-oval, moderately convex, piceous-black in color ; prothora.x twice as wide as long, strongly narrowed from base to apex, with the sides evenly and feebly arcuate, the base broadly and feebly lobed, feebly oblique and sinuate laterally, the surface rather strongly but not densely punctate, with a fine exca- vated median line not attaining base or apex ; elytra three-fourths longerthan wide, rather strongly but not very closely punctured; under surface black, the legs rufo-piceous ; pubescence throughout dark in color, uniform, short and not con.spicuous ; antennae as figured under Atlagemts.

Apparently rare ; I have before me only a single specimen in rather poor state of preservation.

Perimegatoma Horn.

In this exclusively western genus, which belongs to an important section of the Attagenini differing from those above considered in the elongate basal joint of the tarsi, the antennal club is 3 -jointed, with its two basal joints transverse and the last elongate, though to a less degree than in Attagenus. The prosternum is strongly deflexed at tip to form a protection to the mouth in repose, as in most of the other

genera of the family, the process between the coxje moderately nar- row, the mesosternum narrow and divided throughout by a relatively wide parallel sulcus. The hypomera are moderately and indefinitely concave, and the metacoKal lamina short. Belfrai;ei, which is assigned to the genus by Jayne, undoubtedly forms the type of a distinct genus because of the 5-jointed antennal club ; it is therefore not considered in the following table, which comprises all the species known to me : — Last joint of the male antennal club short, scarcely one-half longer than the two pre- ceding combined 2

Cylindrica of Kirby (Saskatchewan), and annularis Mann., (Alaska), are not known to me at present, the former is said to be distinguished by its uniform elytra! vestiture and was assigned by Kirby to Attagenus ; it was considered to be the same as piceus by Gem- minger and Harold, but is probably different, as it is said by the author to rese.vible a Ctypiophagiis. The Attagenus angularis of Man- nerheim, seems by the description to be uniformly pubescent, except toward the hind angles of the prothorax, where the hairs become whitish and condensed ; it cannot be the same dLsJaynei, of the above list, which latter was considered to be cylindrica, var. C, by Horn. The. falsa of Horn, is evidently a rare and local species, entirely un- known to me, having the male antennal club slightly longer than the funicle, with its first joint " extremely short " — language which will not apply to any other species known to me — and the last joint more than twice as long as the two preceding together and pointed at tip ; it occurs at and near Sta. Barbara, California.

The pronotum throughout the genus is coarsely and very closely punctured, and there are generally two small and very shallow sub- basal fovea at outer fourth, in which the punctures become still more crowded and coalescent. The species are difficult to identify, as there is a strong mutual resemblance throughout. Aiiipla, however, is a very striking species, differing enormously in the relative size of the sexes ; the females are the largest by far of the entire genus. Generally the divergence of the sexes in this respect is not quite so noticeable as in Attagenus, although the paucity of material before me will not allow of definite statement in this regard.

Trogoderma Latr.

In this genus the body is oblong-oval, less elongate than in Feriine- gatoma but almost similarly clothed with variegated pubescence. The species described by Dr. Jayne under the name Trogoderma simplex, seems to have a somewhat unusual construction of the side pieces of the prosternum, and it should therefore form the type of a distinct genus ; it is unknown to me.

152 Journal New York Entomological Society. [Voi. viii.

The antennas are of a different type of structure from that pre- vailing elsewhere in the tribe, the club being 6- to 8-jointed and generally loose and serriforni in the males, and 4-jointed and regular in the females. The prosternum is not so strongly defiexed at apex as in Perimegatoma, and the process between the coxfe is wider, the mesosternum between the coxas \ery much wider, transverse and divided throughout by a broad deep sulcus.

Dr. Jayne was mistaken in his diagnosis of the species of the sfenialis group in two important particulars. The mesosternum is as completely and widely divided by the median sulcus as in the others, but the metasternal process is rather more arcuate, and the broad flat marginal bead usually extends along the apex throughout the width ; this misled the author in determining the true anterior limit of the metasternum. The author also failed to observe the true structure of the male antennse, the very minute third joint giving rise to the ap- pearance of a lo-jointed condition, which is alluded to as a general fusion of the tenth and eleventh joints in the male (Proc. Am. Phil. Soc, XX, p. 363).

The species are quite numerous and those before me may be thus briefly characterized : —

Eyes entire, the inner frontal margin not sinuate; antenn;^ serrate in the male 2

Eyes sinuato-emarginate at about the middle of their inner frontal edge ; male antennte compact, not serrate, the third and fourth joints subequal and transver.se ; prono- tum minutely, sparsely punctate, becoming strongly and more densely so toward

to be very rare in individuals, and it is seldom that more than a single one it taken at any one time ; most of the species, which appear how- ever to be abundantly distinct among themselves, are therefore repre- sented at present by unique types. Peri- ^.^^^ ^ megatoma resembles it in this respect to some extent. The pale coloration of advena may be due to immaturity, at least partially.

These antennal differences, although marked, are not indicative of subgen- eric groups, as the general structure of the under surface, and partic- ularly of the hypomera, is indentical throughout.

There are a few other apparent species indicated by inadequate or poorly preserved material, and the genus is evidently a large one. In striking contrast to Trogoderma, individuals are abundant when dis- covered, and most of the species are represented by good series. The species fi/sculiim of LeConte, which is entirely valid, is said by Dr. Jayne to inhabit the Atlantic regions ; it is however Sonoran, and was

not correctly identified, and tristc is not an Atlantic, but a Pacific, species. One female of apicale in my cabinet has the two joints of the antennal club equal in length : as it is not in very good condition, 1 cannot state whether it differs specifically. The remarks m&de by Dr. Jayne in regard to the female of halteatum are erroneous, as the antennal cavity is normal in form. The same author gives " Cali- fornia" as the locality oi nificonie, whereas it is confined in reality to the southern Atlantic States. Picicorne, described by LeConte from the southern Atlantic regions, is unknown to me, but is probably a valid species.

Anthrenini.

The distinguishing characters of this tribe are the compact body, very retractile legs and the deep and acutely defined fossae for the antennal club. The tarsi are short and rather slender, the basal joint of the posterior distinctly shorter than the second, the next three subequal or progressively decreasing slightly in length. The mouth parts are completely protected in repose by the deflexed prosternum. The antennae vary in the number of joints, but these divergencies do not indicate more than subgenera, as the structure otherwise is quite homogeneous. There is but one genus : —

Anthrenus Geojf. The eyes may be sinuato-emarginate within or entire as in Trogo- dcnna, and are finely faceted as usual. The prosternal process is rather narrow, impinging upon the transverse, deeply sulcate meso- sternum, also as in that genus. The species are moderately numerous, and number among them some of the most destructive enemies of dried insects preserved in cabinets ; those before me may be easily identified as follows : —

Eyes emavginate ; antennfe ll-jointed, the club broadly oboviform and composed of three closely connate joints of which the two basal are strongly transverse and much shorter than the last ; body clothed with broad scales. [Anthrenus i n s p . ] 2

A form which I have not seen was described by LeConte, from New York, under the name flavipes ; this was supposed by Jayne to be the same as the European allndiis of Brtille, and may ha\'e been founded upon an introduced individual of that species, which in my opinion is distinct from scrophiilarice, although inscribed as a variety in the catalogues; s/'x/urf/zs and p/v/e/zs appear to be identical and to form a variety of albidus, but sencx may be another distinct species. The two European species museontiii and fiiscus are introduced above into the table, although I have never seen any examples taken in this country. Those mentioned by Jayne may have been adventitious im- portations. Erom the illustrations given of the antennse, however, it is probable that Dr. Jayne did- not have the true nmsconim before him at all, but mistook the rnuch smaller castanece for it ; miiseonim might therefore be stricken from the American lists. Verbasci and its varie- ties constitute the chief destructive element of entomological collec- tions in temperate climates, but I have never known of any such habits in scrophulariiv or allied species.

'rKiNoniNi. Tin's tribe includes at present l)ut two very anomalous minute species, differing radically in sternal structure hut perfectly homo- logous otherwise, and inhabiting the paUi^arctic and nearctic regions respectively. They represent two distinct genera as follows : —

AiilLTior cox e iianowly se[)aratcJ, the process feebly caiiiKite, free and received at tip witliin a deep anterior excavation in the broad mesosteniuni ; tarsi sliorter, the lirst joint of the posterior but little longer than the second. Europe

Anterior coxx more widely separated, the interco<al [jrocessilat, non-carinate and ex- tending beneath the anterior margin of the still bro.ider mesosternum, which is free, arcuate and feebly deflexed ; prosternura more dellexed at apex, the tarsi longer with the basal joint more elongate. Eastern America Apsectus

In both these genera the hypomera are flat, becoming broadly, feebly impressed posteriorly, the antenn;x3 long, with very sleiider shaft, received in repose within a narrow groove beneath the eyes, ex- tending posteriorly for a short distance along the suture separating the prosternum from its hypomera, the club 3-jointed, with the two basal joints small, the third large and oblong-oval. The legs are slender and free, the posterior retractile, the hind coxal plate very short, but little longer internally and extending only to the wide parapleurse, which are in a single piece.

Apsectus Lcc.

The single species seems to be rare, though rather widely dis- tributed ; its general characters are as follows : —

Oval, convex, piceous-black, polished, sparsely clothed with long erect and bristling fulvo-piceous hairs, each of which completely fills at base a very minute punc- tule, which, consequently, only become distinctly visible on the removal of the bristles ; prothorax transverse, closely fitted to the elytra and lobed as usual at base, the lateral edges entirely devoid of acute margin anteriorly but with an acute and narrowly reflexed margin in basa? two-thirds, the surface with a fine deep groove in outer third, closely paralleling the basal margin ; scutellum large, flat, equilatero-triangular ; elytra wider than the prothorax and more than three times as long, evenly and conjointly rounded behind ; under surface .sparsely and very minutely punctulate, the pubescence shorter ; legs and antenna; testaceous throughout, the large terminal joint of the latter blackish. Length 1.5 mm.; width 0.9 mm. Texas (Austin) hispidus Mehh.

The ocellus is unusually small and feeble in Apsectus but is much more distinct in Tri nodes. I have seen specimens, either of hispidus or a species closely allied, collected by Mr. Schwarz in Arizona, but probably in the higher regions.

Orphilini. This tribe is quite as anomalous as the Trinodini, and differs from any other in having the metacoxal plate well developed, almost equal in length throughout the width and extending to the sides of the body. The head rests in repose upon the vertical pointed plate form- ing the prosternum between the coxai, and the body is glabrous. The legs and head are strongly retractile, the mesosternum transverse and even between the cox^e and the epipleurre well defined. We have a single genus which is also pala^arctic in range : —

Orphilus Er.

The body is compact, oblong-oval in form, moderately convex, the elytra impressed along the suture except at base and with rather prominent humeral callus, the prothorax at base as wide as the elytra, to which it is closely fitted, the base broadly lobed in the middle. The scutellum is well developed and ogival in form. The tarsi are slender, glabrous, much shorter than the tibias and the two basal joints of the posterior are subequal and each rather shorter than the third or fourth, which also are subeipial, the fifth about as long as the first three together. The antenn;i2 are ii -jointed, with a broadly oval compact club composed of three transverse free joints, and the eyes are emarginated by the short post-antennal sides of the front. The species are rather closely allied among themselves, and those repre- sented in my cabinet may be distinguished as follows : —

Integuments deep black, without metallic lustre 2

Integuments Ijlack, with bright steel-blue reflection 4

Individuals of tlie various species appear to be abundant, and the genus, both in nuniber of species and relative abundance, is much better represented in America than in Europe. Nign- of Rossi, (= glal>rafus Fabr.), is the only European species, and its occurrence in this country has not been confirmed.

C10ID./E. Maphoca, gen. nov. The genus based upon the following characters may be placed for the present near Plcswcis. The body is narrow, parallel and moder- ately convex. Head well developed, wider than long, only moder- ately inclined, the eyes slightly behind the middle, remote from the base, moderate or rather small, entire, convex, relatively rather coarsely faceted, the facets individually strongly convex ; front broadly and evenly arcuate from eye to eye, with a small transversely oval inclosed clypeus defined by a very feeble suture, the labrum small, rounded. Antennae inserted under the sides of the front immediately before the eyes, short, 9-jointed, with a moderately developed loose parallel 2-joi'nted club, the two basal joints enlarged; three to six forming a slender shaft ; third as long as the next two combined ; four to six small, moniliform, the seventh transverse and wider. Maxillary palpi well developed, the last joint large, oval, slightly longer than wide, narrowly truncate at tip, the labial very minute ; buccal opening small, the mentum very minute, longer than wide. Antennal grooves before the eyes rather distinct, the buccal processes almost obsolete ; mandibles short and stout, bifid at tip. Prothorax widest toward anex, the disk even throughout and slightly convex ; prosternum long before the coxa, broadly truncate, the intercoxal process narrow. Elytra completely enclosing the abdomen, striato-punctate. Scutel- lum small, transversely oval or broadly angulate behind. Abdomen with five perfectly mobile segments, the sutures straight throughout, the first segment unmodified, as long as the next two combined ; two to four decreasing scarcely visibly in length, the fifth scarcely longer than the fourth and rounded. Anterior coxas small, very deep-set, transverse, the cavities narrowly open behind and angulate externally ; intermediate and posterior narrowly separated, the latter extending nearly to the sides of the body, the met-episterna extremely narrow. Mesosternum even, transversely convex, the metasternum large. Legs

rather short, slender, the femora but slightly dilated, the tarsi much shorter than the tibiae, 4-jointed, the three basal joints small, the first with a brush of long hairs beneath, the fourth long and notably stout, the claws well developed, divaricate, slender, simple and arcuate. Epipleurje extending almost to the sutural angles but narrow throughout, scarcely at all dilated but horizontal toward base, inflexed behind the middle.

The extremely minute species having the assemblage of characters given above is one of those aberrent forms continually occurring among the serricorn Clavicornia. It may be described as follows : —

Body narrow and parallel, testaceous, the elytra blackish and the under surface piceous, the legs and antennje pale ; sur^jce rather shining ; head nearly three- fourths as wide as the prothorax, the antennce as long as the width of the head ; [irothorax about a fourth wider than long, the sides rather prominently rounded at apical fourth, thence feel)ly convergent and straight or broadly, feebly sinuate nearly to the basal angles, which are somewhat obtuse ; apex broadly arcuate, ecjual in width to the base, which is even and subtruncate ; disk feebly convex, declivous at the sides, very minutely and feebly margined at base, minutely and rather sparsely punctate, each puncture with an extremely minute hair ; elytra nearly twice as long as wide, scarcely visibly wider than the prothorax, rather obtusely rounded at tip, the sides parallel and almost straight, the humeral angles right and well defined ; disk with even feebly impressed series of small punctures, the intervals each with a series of extremely minute punctures, each of which bears a very short, stiff erect hair. Length 1.05 mm.; width 0.35 mm. California (Mokelumne Hill, CalverasCo.) — Dr. F. K. lilaisdell blaisdelli, sp. nov.

No notes concerning the habits of this species have come to me, but probably they do not differ from those of other members of the family.

MELANDRYID^.

Tetratomini. The definition of this tribe must be enlarged to include all those Melandryids, with simple claws, which have the outer three or four antennal joints abruptly dilated to form a strongly developed loose and parallel club. The genera may be defined as follows : —

Last four joints of the antenna? dilated ; eyes well developed, emarginate anteriorly ; pronotal fovea; distinct 2

Last three joints abruptly and strongly dilated, forming a loose clul) ; eyes emarginate or sinuate anteriorly, generally less developed ; abdominal sutures moderately fine ; edges of the prothorax subeven 4

The last two of these genera were mutually confounded by LeConte and Horn, and both considered identical with the European tritomid genus Triphyllus. Pisenus resembles the latter considerably in form, and the noting of the 4-jointed hind tarsi, antennre and pronotal fovea? no doubt led the distinguished authors astray; an inspection of the an- terior and intermediate tarsi, which are 5 -jointed, would have enabled them to avoid the error.

Tetratoma Fabr.

This holarctic genus contains several species in the European fauna, and the two following American species seem to be perfectly con- generic, as far as can be judged by the descriptions : — Elongate -oval, strongly convex, rufo-testaceous, the head and antenna; black, the elytra steel-blue ; body above polished, glabrous, except that each puncture en- closes an infinitesimal hair ; antenna; well developed, nearly two-fifths as long as the body, the club as long as the entire preceding portion, the joints quadrate or oblong, the last a little longer and pointed and all pedunculate at base ; prothorax transverse, as wide at base as the base of the elytra, narrowed moderately from base to apex, the latter scarcely at all sinuate, with the angles broadly rounded, the base very broadly and feebly lobed at the middle and finely margined through- out like the sides, the latter broadly and very feebly irregular or subundulate ; basal angles obtuse but not in the least blunt or rounded ; punctures rather coarse and sparse, the basal fovea; distinct, deep and punctiform ; scutellum moderately transverse, cordiform, finely punctured ; elytra three-fifths longer than wide, a little more than three times as long as the prothorax, rather wider behind the middle than at base, thence rapidly, arcuately narrowed to the subogival apex ; humeral callus obtusely prominent ; punctures coarsely impressed and sparse ; under surface more finely but rather sparsely punctate and sensibly pubescent ; basal joint of the hind tarsi about as long as the last. Length 4.7-5.8 mm.; width 2.1-2.65 mm. Northern Atlantic regions truncorum Lee.

Elongate-oval, convex, finely and sparsely pubescent, shining, piceous with a red- dish tinge ; legs and base of the antenna; yellowish-brown ; head more finely punctured ; prothorax and elytra equally punctured, the former transverse, narrower in front, rounded at the sides which are narrowly margined, the base margined like the sides and with a large puncture half way between the middle and the basal angle, the latter obtuse and rounded. Length 4.0 mm. Colorado (Yeta Pass) COncolor Lcr.

The latter of these species I have not seen, but, from the originally published characters reproduced above, it would seem to be provision- ally attachable to the true Tcfrafoma ; the principal differences appear to reside in the pubescence and in the rounded basal angles of the prothorax.

Abstrulia, gen. nov.

The species of this genus differ greatly from tnincorum in general habitus and in the structure of the sides and base of the prothorax. The irregularly crenulate sides of the latter are prominent just before the middle and at basal third or fourth, and the disk is concave along the basal margin, with the fovece larger, deep and more impressed or less punctiform, the scutellum smaller and more nearly subquadrate, and the elytra are dark in color with a complex maculation of pale spots, the punctures coarse, impressed and sparse. The surface is sparsely but distinctly pubescent, and the basal joint of the hind tarsi is, as a rule, obviously shorter than the last. The species are mutu- ally closely allied, anci the three before me may be thus defined from the male : —

Basal joint of the hind tarsi very much shorter than the last 2

Basal joint scarcely visibly shorter than the last 3

2 — Oblong-oval, convex, polished, pale piceous-brown in color, the legs and antennse concolorous, the elytra blackish with pale flavous and sharply defined intricate markings, the pale areas together somewhat exceeding the dark, and having as a prominent feature a subsutural obverted C-shaped mark on each extending near the suture to apical two-fifths ; antennoe scarcely as long as the head and prothorax, the club distinctly shorter than the stem, cylindric, rather compact, the joints wider than long, the last a little longer than wide and conically pointed, the seventh joint transverse and forming a gradual passage to the club, third as long as the next two combined ; prothorax short, nearly twice as wide as long, the base and apex equal in width, the latter transverse, narrowly and feebly sinuate at each side, the middle broadly arcuate and as advanced as the very broadly rounded angles, the base broadly, feebly lobed at the middle, the angles very obtuse but not rounded ; punctures coarse and rather sparse, but not as coarse or sparse as those of the elytra, the pubescence distinct ; elytra three and a half times as long as the prothorax and equal in width, two-thirds longer than wide, parabolic behind, parallel at the sides ; basal angles obtuse, the cal-

Oblong-oval, more convex, polished, black, the antenna: piceous toward base, the legs dark testaceous, the elytral pale markings rufo-testaceous and together not occu- pying as much area as the black ground, the subsutural pale .spot not extend- ing behind the middle and not forming an obverted C-shaped macula ; antennte nearly as in tessellata but black and stouter, the third joint very much shorter than the next two combined ; prothorax much more convex, distinctly less than twice as wide as long, the sides broadly arcuate, converging anteriorly, the prom- inence before the middle almost obsolete ; apex much nanower than the base and broadly sinuate ; punctures moderately coarse and sparse ; elytra nearly similar in form and sculpture, as wide as the prothorax but only three times as long ; under surface finely, sparsely punctate. Length 3.0 mm.; width 1.4S mm. Pennsylvania variegata, sp. nov.

3 — Body throughout nearly as in tessellata but black, the antenna; concolorous, the periphery of the pronotum rather paler, the legs piceo-testaceous, the elytral pale niaculation nearly similar but less extended, much less in area than the black ground, the subsutural C-shaped marks before the middle much shorter and not extending distinctly behind the middle ; antenna nearly similar in structure but stouter, and with the third joint very much shorter than the next two combined ; prothorax and elytra nearly similar in form, the former a little narrower at apex, with the apical angles somewhat more advanced and much less broadly rounded, the pubescence longer and more conspicuous ; lateral prominence before the middle equally conspicuous and much more so than in variegata. Length 2.9 mm.; width 1.4 mm. Indiana. — Cab. Levette... maculata, sp. nov.

In tessellata the male has a large and very abruptly limited deep oval excavation, slightly wider than long, .occupying almost median third of the fifth ventral, and extending from the apex almost to the base, the bottom of the excavation polished, impunctate and glabrous, with a very few piliferous punctures posteriorly ; in maculata it is equally deep and abrupt but smaller, occupying about median fourth and is more distinctly pubescent posteriorly; in variegata it is as large as in tessellata or larger, but very much more shallow.

Incolia, gen. nov.

In this genus the body is much more elongate and less convex than in either of the preceding, and differs greatly in abdominal structure and somewhat in its finer sculpture ; in the form and structure of the antenncX and prothorax it is nearly similar to Abstritlia. The single species may be described as follows from the unique type, which ap- pears to be a female : —

Body elongate, parallel, feebly convex, polished, blackish, the antenntv toward base, legs, limb of the pronotum and an indefinite oblique elytral streak, extending for

Length 3.8 mm.; width 1.6 mm. Indiana? longipennis, sp. nov.

The locality i,s reasonably certain, but the type bore no label in the cabinet of the late Dr. Levette. I considered this to be the coiicolor of LeConte, for some time, but the description will not serve, espe- cially regarding the " narrowly margined " sides of the prothorax of

concolor.

Eupisenus, gen. nov. This is the only genus of the tribe Tetratomiui which has been discovered thus far on the Pacific coast, the others all being inhabi- tants of the Atlantic districts. The body is elongate, parallel and moderately convex, with the prothorax relatively narrower than in the preceding genera, and the elytral humeri somewhat exposed at base. The following description of the only known species will bring out other characters which may prove to be generic : —

Parallel, polished, sparsely clothed with short fine and subdecumbent pubescence, black, the legs, antennae, trophi and elytra pale luteous, the latter indefinitely shaded with piceous at the middle of the flanks and pn the suture toward tip ; antenniv rather stout, as long as the head and prothorax, the third joint about as

long as the next two together, eighth globular and perfectly similar to the seventh, the club very strong, parallel, the joints rather closely connected and strongly transverse, the last pointed and but little longer than wide ; prothorax three- fourths wider than long, not more than two-thirds wider than the head, widest near basal third, the sides broadly arcuate, gradually converging anteriorly and almost even, the apex sensibly nan-ower than the base and broadly arcuate ; basal angles slightly more than right and not at all rounded ; surface rather coarsely and closely punctate ; elytra parallel, obtusely and broadly rounded behind, four- fifths longer than wide, three and a half times as long as the prothorax and nearly a fourth wider, the punctures moderately fine but deeply impressed, somewhat close-set and nearly similar in size to those of the pronotum ; humeri obtusely rectangular, the callus distinct ; scutellum moderate, transverse ; under surface polished, finely, rather sparsely punctured ; legs slender, the four basal joints of the anterior and middle tarsi short, subequal and together but little longer than the last; basal joint of the posterior much shorter than the last. Length 4.5 mm.; width 1.65 mm. Alaska and southward elongatUS Lee.

The head has a deep frontal impression at the middle of the line between the antennae apparently in both sexes.

Pisenus, gen. nov. The species of this genus may be readily distinguished from the preceding by the shorter, more oval form, greater convexity and much smaller size, as well as by the characters of the table ; the prothorax, also, is as wide at base as the base of the elytra, so that the humeri are not exposed at base, and the sides of both form a virtually continu- ous arc. The antennee are nearly similar in structure. The two spe- cies are the following : —

Body more elongate-oval, shining, clothed sparsely with rather short fine subdecum- bent pubescence, black, the legs and antennse dark testaceous, the basal regions of the elytra, especially at the humeri, suffusedly rufous ; head about as wide as the rectilinearly truncate apex of the prothorax, the antennae stout, fully as long as the head and prothorax, the eighth jomt similar to the seventh and the club similar to that of Eiipisenus elungatus but narrower ; prothorax three-fourths or more wider than long, the sides almost perfectly even and broadly arcuate from the distinct basal angles to the apex, the latter much narrower than the base ; surface rather finely but strongly, moderately closely punctate ; scutellum trans- verse, broadly angulate behind ; elytra suboval, rather ogivally pointed behind, scarcely at all wider than the prothorax and three times as long, two-thirds longer than wide, the punctures only moderately coarse, impressed, larger than those of the pronotum and somewhat sparse ; under surface finely, rather sparsely punc- tate ; legs moderately slender, rather short, the tarsi short, with the four basal joints of the anterior and intermediate equal among themselves and together about as long as the fifth, the last joint of the posterior very nearly as long as the first three combined.

172 Journal New York Entomological Society. [Voi vin.

Body nearly similar to the preceding but shorter and more broadly oval, strongly con- vex, shining, rufo-testaceous throughout, the pubescence long, coarse, rather abundant and conspicuous, ashy in color ; head smaller, notably narrower than the apex of the prothorax,*the antennae similar to those of humeralis but still stouter, and with the third joint very much shorter than the next two combined ; prothorax similar but only a little more than one-half wider than long and with the punctures coarse, deep and densely crowded ; elytra sensibly wider than the prothorax and two and a half times as long, the sides slightly arcuate toward base, the apex gradually, rather narrowly rounded, one-half longer than wide, the punctures rather smaller than those of the pronotum and somewhat sparse, moderately coarse toward base, especially externally, gradually fine posteriorly ; under surface finely, very densely punctate ; legs rather stouter, the tarsi short but slender, the last joint of the posterior as long as the first three combined. Length 2.75 mm ; width 1.4 mm. Virginia pubescens, sp. nov.

In no individual of the Tetratomini that I have seen, is there the faintest trace of serial arrangement of the always conspicuous elytral punctures at any part of the surface ; the placing of Tetratoma near Triplax, by Redtenbacher, is an unaccountable error for this, as well as a multitude of other reasons, besides the radically different formation of the tarsi and palpi.

NEW SPECIES OF FLORIDIAN NOCTUID.E.

By John B. Smith, Sc.D.

llae following species, with one exception, were taken by Mrs Annie Trumbull Slosson to whose kindness I owe the types which will be dei)Osited in the U. S. National Museum.

It is more than probable that all these are really West Indian or Central American types; but I have been unable to identify them with any described species.

This does not include all the new species taken by Mrs. Slosson ; a few are to be described in a paper prepared for the Proceedings of the United States National Museum. There are here a number of new generic types, some of which are very peculiar. Erastria strigulataria, sp. nov.

Ground color alight sepia brown, mottled, streaked and overlaid by white scales. Head and thorax without distinct maculation. Primaries with the hues confused, the whole wing streaked in appearance, the s. t. line contrastmgly marked, as the on y prominen? feature in the wing. T. a. line single, brown, w:th long ou er teeUa broLn, incomplete. T. p. line single, brown, linear, outcurved over the cell, w.th a deep narrow sinus from the outcurve to the cell, itself, and another broader sinus which extends inward to the t. a. line. S. t. line whitish, oblique, with a broad on- ward tooth at middle, preceded by a brown shade, the terminal space darkemng a ht- I to the fringes. A series of small, black venulardots, beyond which the fringes are cut with white. Fringes white-tipped at the anal angle. The o>^di nary spots are marked by a black line in the cell. Secondaries even, smoky brown ; abroken black terminal line, fringes partly white-tipped. Beneath, primaries brown, the termina space overlaid by white scales; secondaries whitish, with a brown central lunule and a broad outer band of brown scales, irregular, broken and diftuse.

Expands 27 mm. = 1.08 inches.

Habitat: Florida (Mrs. Slosson), i female only.

Unlike any of the described species and will be separated generic- ally when more material is at hand. The specimen before me is de-

fective in the body parts ; but the wings are in good condition. The apices of primaries are pointed and the middle of the outer margin is marked. Vein 5 of the secondaries is as strong as the others and is on a little spur from the junction of 3 and 4.

Fagitana obliqua, sp. nov.

Ground color velvety red-brown, the vestifure thick. Head and thorax without markings. Primaries without strong contrasts. Costal region a little paler, outer half of median space distinctly deeper red-brown, the median lines more yellowish. T. a. line outwardly margined with brown ; starts from costa two-fifths from base inwardly oblique to inner margin at basal third. T. p. line margined by brown on both sides, evenly oblique, nearer to apex on costa than to the anal angle on inner margin. S. t. line brown, sinuate, hardly relieved. A series of brown interspaceal lunules just before the margin, which has a darker, followed by a pale line at the base of the concolor- ous fringes. Orbicular nanow, elongate, upright, faintly outlined by somewhat paler scales. Reniform lost in the darkening of the outer half of the median space. Secondaries evenly red-brown. Beneath red-brown, secondaries and terminal space of primaries somewhat paler.

Expands 27 mm. = 1.08 inches.

Habitat : Florida (Mrs. Slosson), one female.

One example only, in fair condition. The secondaries have v. 5 as strong as the others, and on a little spur from the median. The species differs at once from littera by the lack of all white markings in the primaries. This resembles very strongly the Diantlixcia tura Druce, Biol. Cent. Am. Heter., p. 291, pi. 27, f. 19 ; but is different, I believe. At all events the new species is not a Diauthixcia and, as it comes from a different faunal region, I will risk describing it.

Anticarsia ferruginea, sp. nov.

Ground color a bright, rusty-red brown, the vestiture a little rough. Head and body parts immaculate. Primaries with an upright, linear, white, contrasting reni- form and a broad, richer brown, central median shade, which, continued across the secondaries, forms a more definite brown band. T. a. line purplish, single, broken, with three small, irregular outcurves in the interspaces. T. p. line blackish, linear, even, incurved on the costa, outcurved over the cell, then almost evenly oblique to the inner margin. S. t. line is a series of blackish, diffuse, interspaceal spots, bisinuate in general course. A series of difi^use, blackish, terminal, interspaceal marks. Reniform as de.scribed ; orbicular, punctiform, whitish. Median band broad, diffuse, angulated on the median vein. Secondaries with the t. a. line con- tinued half way across the wing. A moderately broad, well-defined median brown band across the middle, forms the continuation of the t. p. line and the median shade. The series of s. t. spots is continued across the wing. Beneath, more powder}' and rusty, markings of upper surface reproduced in a general way, the ordinary spots of the primaries being blackish instead of white.

Expands 35 mm. =1.40 inches.

Sept. igoo.] Smith; New Species of NocxuiDyE 175

Habitat: Florida, Mrs. Slosson.

The type and only specimen before me is a female in good con- dition, obviously different from the described species in our own fauna and, I believe, from other described forms as well.

Capnodes punctivena, sp. nov.

Ground color dull red-brown, a little irrorated with paler scales Head and thorax concolorous. Abdomen with a little white line at each side along the margin of the second abdominal segment, else concolorous. Primaries without contrasts, the median lines marked by a series of white venular dots in a diffuse dusky line, which does not contrast to any great extent with the ground color. A white dot at base of median vein. T. a. line almost upright, a little outcurved. T. p. line outcurved over cell, incurved below, the median space being narrow as a whole and very narrow on the internal margin. S. t. line irregular, broken, composed of somewhat lunate pale marks which are preceded by irregular dusky shadings. Through the terminal space there is a series of yellow scales along the veins, a series of small, yellow, inter- spaceal terminal dots and blackish scales between them. The reniform is vaguely in- dicated by a dusky shade. Secondaries with the dusky portion of t. a. line traceable. T. p. line crosses the middle and is feebly bisinuate, the veins white dotted. S. t. line a series of dusky interspaceal spots followed by a paler shading. The terminal yellow dots are more elongate and toward the anal angle more resemble a broken line. Beneath, uniform fuscous brown, the secondaries with a linear, short, black, discal spot.

Expanse 27 mm. =: 1. 08 inches.

Habitat : Charlotte Harbor, Florida (Mrs. Slosson).

A single female, in good condition. It is possible that this can- not remain associated with Capnodes when the male is known. The middle tibise seem to have no spinules and the antennae are ciliated and bristled : — rather an unusual female character. The maculation is very simple and not at all contrasting.

Kakopoda, gen. nov.

Habitus and form of an Erebus and referable to the ErebiincE in body and wing form, in the continuous lines crossing secondaries, and in the quadrifid median vein of secondaries, on which the cell is short. Palpi long, oblique, second joint much the longest, terminal short and stout, exceeding head by half their own length. A small, pointed, frontal tuft. Antennae of the male with long lateral bristles on each joint. Legs in male abnormal. The median tibia is stout, somewhat shorter than usual, terminated by a single spur only. The posterior tibia is decidedly shorter than normal, there is only a single terminal spur, while the median spurs are very close to the base and unusually long, unequal, one of them ^ the other 3^ as long as the femur. There are no spines or other armatures. Primaries triangular, apices pointed, outer margin long, oblique, rounded, and even.

This genus is well marked by the peculiar malformation of the

middle and posterior tibite, otherwise resembling Se/eiiis in size and general appearance.

Kakopoda cincta, sp. nov.

Ground color red or umber brown shaded with bluish and black, the lines black. Vertex blackish. Upper side of antennas at basal third, smoky brown. Collar black- ish brown at base. Thorax with an anterior, median and posterior blackish, trans- verse line. Abdomen smoky black at base, obscurely ringed to the apex, which is yellowish brown. Markings of primaries distinct. Basal line geminate, blackish, marked by a paler inclosed shade on the costa. T. a. line geminate, inwardly oblique, a little arcuate, inner line narrow, smoky, outer broad, blackish, a little diffuse, in- cluded space paler on the costa. Throughout the basal space is a bluish shading and a blackish transverse line. The t. p. line consists of a narrow, thread-like paler line, preceded by a prominent black line varying in width, shading inwardly into brown, followed by a steel-blue line which is outwardly diffuse, and shade into the subter- minal space; varying in width. In course it is irregularly sinuate, as a whole about parallel with the outer margin. A narrow, obscure, blackish line runs parallel with, close to and within the t. p. line. Median shade line narrow, blackish, irregular. Reniform blackish, indefinite, moderate in size. S. t. line diffuse, yellowish brown, irregular, angulated below the apex and there emphasized by a preceding black shad- ing. A black, festooned terminal line. Secondaries with the lines of primaries con- tinued, but more crowded toward the center of the wing, leaving the basal and s. t. space clear ; the latter yellowish brown, and forming a short band which joins and matches the last abdominal segment. Beneath yellowish, smoky, both wings crossed by three median, darker, somewhat crenulated lines, and by a looped or festooned terminal line.

Expands 28 mm. = 1.12 inches.

Habitat : Biscayne Bay, Florida (Mrs. Slosson).

A single male only, in good condition. The species should be readily recognizable, though the lines probably vary somewhat and the relative intensity of colors of the maculation may be considerably changed.

Egryrlon, gen. nov.

Head moderate in size, well applied to the thorax, but hardly retracted. Eyes hemispherical, hardly prominent, hairy. Front smooth, hardly convex, with a pointed frontal tuft. Antenna; in the female simple, in the male (?). Palpi long, a little oblique, projecting half their length above the front. Middle joint a little the longest, stout, rather closely scaled ; terminal joint more slender, a little flattened, almost equal throughout and obtuse at tip. Thorax about as broad as long, only a little convex, vestiture mixed hair and scales, rather close. Legs moderate in length, closely scaled, except that the middle tibia has a brush of loose vestiture at about the middle. Abdomen conic, closely scaled, scarcely exceeding the anal angles of the secondaries. Primaries trigonate, broad, outer and inner margin of nearly equal length, outer margin arcuate. Secondaries proportionate ; discal cell short, vein 5 as. strong as the others and referable to the median series.

Sept. igoo.] DyaR : LiFE-HlSTORY OF LaCOSOMA ChiRIDOTA. 177

This genus belongs to the Erebiid series, is nearest to Trama in general appearance, and is the first example known to me of the oc- curence of hairy eyes in combination with other characters. Unfor- tunately I had no male.

Egryrlon filaria, sj). nov.

Ground color dark chocolate brown. Head, thorax and abdomen without mark- ings. Primaries with the median lines narrow, contrasting pale blue, the t. p. line followed by a bluish shading, which is broader toward the inner margin. The veins as they cross the t. a. line are a little blue powdered a short distance on each side. T. a. line a little outcurved, with a small angle on the subcostal vein, marked on each side by black scales. T. p. line outcurved over the cell, then rivulous to the inner margin. Edged on each side by black scales. S. t. line marked by a series of obscure black spots in the interspaces. There is a series of black, terminal lunules. Reniform small, narrow, upright, a little constricted, outlined by black scales. Sec- ondaries with the t. p. line of pnmaries continued as a sinuate line about three-fifths from base, shaded outwardly by blue scales and inwardly edged by black scales. There is a linear, black, discal mark. Beneath a little paler brown, each wing with a black discal lunule.

Expands 23 mm. = .92 inch.

Habitat: Biscayne Bay, Florida (Mr. Slosson).

One female only, in good condition. The species should be easily recognizable by the clean cut blue lines on the chocolate ground ; the outer is continued across the secondaries.

NOTES ON THE LARVAL-CASES OF LACOSOMI-

D-^ (PEROPHORIDiE) AND LIFE-HISTORY

OF LACOSOMA CHIRIDOTA GRT.

PLATE VI.

By Harrison G. Dyar.

No species of the family Lacosomidse has had its life-history fully written. The best known larva is the North American Cicinnus melsheiinerii Harris, of which the egg, half grown larva and mature larva have been described (see Packard, Ann. N. Y. Acad. Sci., VUI, 50). The youngest larvae known seem to live already in a rude case. The same appears to be the condition in Miniallo (nmilia Stoll (see Sepp, Surin. Ylind., pi. 20). Both these species form at maturity a

178 Journal New York Entomological Society. [Voi. viil

well constructed case ; but the height of perfection in this line is reached in Ciciunns despecta Walk, and allies, which construct a curi- ous case as hard as wood. Of one of these, C. externa, Moore says : " This caterpillar lives in a hard hammock-like case formed of the excrement, joined together with silk and mucilage. The case is sus- pended from the twig on which it feeds by silk threads and is gene- rally slung in a more or less vertical position, so that the curved end protects the upper opening from rain. Both ends of the case are alike and the caterpillar puts his head out at either end with equal fa- cility." (Proc. Lit. Phil. Soc. Liverpool, XXXVI, 54.) Figure 9 of the plate shows a case like this.* Another group of larvae form a case only at maturity, living at first under a net. Concerning one of these, Cicinnus viohii-ea,j Sepp states that the larva when half grown lives in a reticular net, but later makes a case, using silk and pieces of leaves and bark mingled with excrements. (Surin. Vlind., pi. 30.) Such nets on the oak had been known to me for some time, but I did not at first suspect that they had any relation to the Lacosomid». They are quite common in the scrub oak country along the south shore of Long Island from Babylon to the eastern end, and they prove to belong to Lacosoma chiridota, a species usually very rare. Its life- history is as follows :

brown. Skin smooth, segments 3-annulate, setae short and pale but distinct and with enlarged tips ; i, ii and those of the cervical shield and head are especially short and paddle -shaped. Toward the end of the stage the larva enlarges the net, spinning cross threads nearly up to the anchors, strung with frass.

Stage II. — Head .5 mm. As before, the dorsal setje with en- larged tips. Dorsal half of body brown with several fine, pale lines ; subventral region whitish. Shape normal, the cervical shield large, not cornified ; anal end tapering, not truncate ; segments 3-annulate, annulet i large ; feet short, dark brown.

Stage III. — Head .8 mm., pale brown, dotted and with two nar- row pale yellowish lines that continue the addorsal lines of the body ; a spot circled by pale on each side of the apex of the clypeus ; setae pale, the upper ones with bulbous tips. Body striped longitudinally with brown and pale yellowish ; a geminate brown dorsal line ; a broad subdorsal one, continuous with the brown sides of the head ; subventral ridge prominent, pale ; all with sparse pale granules. Joint 2 is as wide as the head, the posterior half of the body widened later- ally ; joint 13 small; subventral region brown, contracted. Setse short, pale. Net 10 x 13 mm. in size (Plate VI, fig. 4). At the end of this stage larva cut a "slit from the edge of the leaf to the eaten part under the net, being the first indication of a tendency to form a case. The larva also fastened the leaf firmly to the twig.

Stage IV. — Head 1.2 mm. , pale yellow, thickly dotted with brown, leaving yellow lines on the sutures and in a vertical band on the face of each lobe. Body yellow, dotted with brown, forming four irregular and broken lines between the yellow dorsal line and substigmatal fold, a little heavier on the thorax and obscurely appearing to meet around the posterior end of the body. Anal plate large, yellow ; cer- vical shield striped like the body. Tubercles small, dark, in pale areas ; iv and v in line, somewhat approximate, with swollen apices. Segments annulate, granular from the primary tubercles. Subventral region dark brown, retracted and invisible from above.

Stage V. — Head 2.1 mm., greenish yellow with dark brown mottlings in vertical streaks, leaving irregular pale areas. Body yellow, lined longitudinally with brown ; addorsal, subdorsal and lateral lines, the intervening yellow lines narrow and somewhat oblique, the brown dark only on the anterior third and posterior tip of the body, fainter luteous centrally ; subventral ridge rather prominent, subventer dark

brown on the thorax, elsewhere faintly luteous. Venter pale, trans- lucent. Feet pale, the abdominal ones very short with crotchets in an ellipse. Spiracles black. During this stage the larva left its net and constructed a rude case by uniting two leaves and partly biting them around. It spun a few threads across the opening.

Stage VI. — Head 2.7 mm. (in small male larva), round, higher than wide, the apex a little under joint 2 ; clypeus very small ; surface wrinkled, shagreened ; pale yellow, heavily mottled with brown spots which form streaks above the clypeus and leave a pale space above on the face of each lobe. Body dull greenish yellow in straight dorsal and in slightly oblique and dislocated subdorsal, lateral and suprastig- matal lines, the subventral line straight and running along the promi- nent subventral fold. Spaces between these lines filled in with dark brown at the extremities only ; /. e., in three bands on thorax and subventually and in irregular spots on joint 13. Spiracles black rimmed. Cervical shield large, with two brown bands on each half. The posterior part of joints 12 and 13, which is dark spotted, becomes transversely folded and assumes, imperfectly, the appearance of a round area, a little flattened, about the size of the hole in the case. The case is made of two leaves or of a single leaf bent over and cut off, the holes at the end made circular by thread. At the end of the stage the larva spins up one end of the case and hibernates. Pupation in the spring. A single brood in the year.

OVIPOSITING OF VANESSA ANTIOPA.

Archibald C. Weeks.

At Richmond Valley, Staten Island, on April 15th, of this year, I was fortunate enough to discover an Antiopa in the act of ovipositing. As the process is one rarely seen its record may be interesting. The locality was warm, sunny and completely sheltered from the wind. In passing through a thicket of pussy willows (Sa/Lv Candida (?)), I almost ran against the butterfly resting motionless, head downward, close to the extremity of a slender willow stem, the catkins of which were not yet in bloom. The wings were extended at right angles with the body, the under side facing the sun, but the primaries were pushed backward so as to cover the secondaries, and in this position the insect perched at the end of the stalk afforded an almost exact counterpart of a blackened and withered bowl-shaped calyx with an irregular and faded out upper edge. Aside from the short catkins, every stem, branch and twig in the vicinity was entirely denuded, the only objects suggestive of leaf or flower being some dried and with- ered seed pods of the swamp Asclepias which still clung to the extrem- ities of the dead stalks. The butterfly, as if realizing how conspicu- ous its situation was, remained as motionless and fixed as possible, without the flutter of a wing, as if forming an integral part of the stalk, only the closest observation availing to detect the movement of the abdomen and the scarcely perceptible advance down the stem — a fine example of protective mimicry. The first eggs were deposited only an inch from the end of the stalk, close to the stem, and encir- cling it just as far as the insect could reach without altering its posi- tion. When discovered the eggs had been half deposited, but the in- sect contined its work entirely oblivious of my proximity and without the slightest change of attitude. The eggs were not laid in regular rows, but in an arrangement somewhat resembling the alternate squares upon a checkerboard having the corners in contact but the sides free. The egg cluster extended irregularly along the stem some two inches, was of a pale yellow color, and contained as nearly as could be computed about four hundred and fifty eggs, probably the entire contents of the ovary ; the lowest, of course, being deposited last. The egg under a lens suggested a musk melon with the surface divided into eight longitudinal sections by as many cream-colored

ribs, each terminating at a small circle at the apex, in the <:enter of which the germ could be distinctly seen. The instinct of the butter- fly in selecting the dwarf willows, which develop earliest, as a deposi- tory for its eggs in spring, while preferring the tree willows for the August brood is a matter of common experience. Last summer a large brood of the larvae of this insect fed on the hop vines in the rear of my Brooklyn residence. A comparison of the number of eggs laid in the present instance with the ordinary number of larvK generally constituting a brood after the second or third adult (50-100) may be used as an indication of the great percentage which never attain ma- turity. The stalk with its egg cluster were preserved in order to note further developments.

Note on Trypcla iiotata.

On March 3d, of the present year, I collected a number of galls oxi Bigelovia (^Ouysothanuiiis) graveolcns (sens. lat. ) at Santa Fe, New Mexico. They were spherical, about 9 mm. diam., with a lateral pointed protuberance ; surface rather thinly covered with appressed wool-like hairs. In due time I bred from these galls numbers of the flies, which 1 took for a nevv Eiirosta ; but Mr. Coquillett has kindly compared them with his Trypeta notata, Jn. N. Y, Ent. Soc, Dec, 1899, p. 262, and finds them identical.

NOTES ON OVA AND LARVA OF HYPERCHIRIA PAMINA.

By Dr. R. E. Kunze.

While collecting in Prescott, Ariz., found a 9 Pamina, June 23, 189S, which oviposited, June 24th, one hundred eggs. I retained thirty, which hatched twenty days later, July 13th, 8 A.M., exact time for first larvae to appear, I sent sixteen ova to Professor Packard, and gave the others to a friend on the Summit Mountains to raise if possible. Nights were very cool, and thought that no ova would hatch, so long in coming out.

6>zw/« white, a black spot on top. Length, 2 mm. Width, i^ mm. Shape subconical, depressed on sides. Ova laid in piles com- posed of parallel rows.

Young /a rvce after hatching: length 5j-6 mm. when in motion, and 4 mm. at rest. Width of body 4 mm. Color dull orange or buff, head black. Dorsum with double row of gray tubercles, sur- mounted by black bifurcated spine. A subdorsal row of tubercles of a greenish-gray. Lateral parts below covered with whitish hair. Head shining black, covered sparsely by whitish hair. Thoracic and prolegs concolorous with body. A few hours after hatching larva changed to a brownish color, spines black. Larvce were fed on Quer- cus undulata.

202 Journal New York Entomological Society. [Voi. viii.

I had to return to Phoenix, where oak does not grow, and there- fore gave Sa//x fluviatalis for larvre to feed upon. Only fifteen accepted the change of food. The others gradually died between July iSth and 21st, and July 23d all were dead.

Larva eight days old. Head shining black, covered with whitish hair ; round in shape. Ground color of body, which is cylindrical, light umber-brown all over, inclined to lighter tints on abdominal parts. Dorsal and lateral parts covered by bunches of spines, which like the shafts are black. Two rows of dor.sal shafts and one each subdorsal. Segments 2 to 4, each bear a transverse row of four bunches of stinging spines. Shaft bifurcated, fork two-thirds as long as the stem, tip surmounted by a long, black, curved spine, and some of dorsal row by two spines. Shafts of segment 2 not so long as of 3 and 4. Segments 5 to 13 each contains a transverse row of four black, tuberculous shafts, each bearing a spine, and those of dorsal row a second rudimentary one. The subdorsal shafts only half so long as those of two dorsal rows. Thoracic legs darker than prolegs. Body sparingly covered by whitish secondary hairs. Length of larva at rest 6 mm., in motion 7 mm. Width i mm.

All the other larvce died inside of two weeks, although feeding constantly on Qiicrciis uiidi/Iafa, an oak they are mostly found on.

On my ne.xt trip to Prescott I found forty-nine spinose, black- looking larvae on Qiicrciis luidulafa, August 8, 1898, which proved to be Pamina. These were gregarious and when disturbed dropped to the ground. They would follow one another like H. lo, but did not rest in similar rows, more sardine-fashion. Apparently the larvi^ represented the beginning of third stage. Examined larvae August nth, at noon. Length of larvae 16 mm. at rest and 18 mm. when in motion, ^\'idth across middle of body 3 mm., and that including spines 5 mm. Antenna; brown, mouth parts light brown. Body covered by six longitudinal rows of black, tapering, spinulated tuber- cles, having on the largest of second joint 19-20 black, fleshy protu- berances or spinules, each with a seta at the end. The two dorsal rows have longest tubercles. On segment 2, tubercles are 4 mm. long. Between the black spines of dorsal tubercles is a mass of whit- ish, woolly hair. Color of body sooty black. Head shining black. A fine white, interrupted dorsal stripe lines each side of both rows of the tubercles on dorsum. There is a white, uneven, interrupted double line between subdorsal and infraspiracuiar row of tubercles.

Sept. 1900.] KuNZE : Ova and Larva of Hvperchiria Pawina. 203

Size of tubercles gradually tapers less toward abdominal segments. At the base of subdorsal and infraspiracular tubercles the spines are white and in bunches. Each segment from the first and including eleventh has six spinulated tubercles. Those of first are not quite so long as on second segment, but longer than any other. Head retracts into first segment. There are five tubercles on twelfth segment, and the dorsal ones longer than on any other joint. On the thirteenth segment are five spinulated tubercles, of which four in a row and the fifth placed behind the two dorsal ones on anal plate. Dorsal tuber- cles of same length as of twelfth segment. Thoracic legs black, feet brown. Prolegs reddish-brown, clasping surface covered by white hair. A longitudinal, reddish-brown stripe, enclosing a white line, passes centrally over entire abdominal surface.

I remained only one week in Prescott, and took three of the larvoe to Phoenix, for further observation, but all were dead by August i8th, when supply of oak gave out. I removed a small bush to Phcenix, planted in a shady spot, but it refused to live under all circumstances. My other larvte of the same brood I left in Prescott, and these were fed up to transformation on Querciis undiilata.

Observed that the tubercles of supra- and infraspiracular row were black, and that all spinules therefrom were white, with a white seta at the end. Of the dorsal rows of tubercles, the white spinules occupied the lower third of each tubercle. Could not distinguish spiracles with a magnifier. A triangular depression above the face, the apex of which meets the vertical line of forehead.

Sept. 9, 1898, received two nearly full-grown larvce from Prescott for observation. Length of larva at rest 38 mm. Width 7 mm. Body of larva cylindrical. Head shining black, with median suture. A triangular depression on clypeus. Mouth parts blackish. Antennae brownish. A few scattering hairs on lower part of face. Width of head 3^2 mm. Anterior part of 2d segment sooty, posterior half white with blackish patch in the middle. Between the subdorsal row of spines, a shining black ridge, with spur between dorsal and sub- dorsal bunch of spines. Ground color of the dorsal surface from seg- ments 3-13, white, relieved by six longitudinal, broken black lines. The dorsal lines farther apart than subdorsal. Li the middle of each segment back of the shaft of spines, are five transverse black dashes. Two of the central dashes are in a continuous broken line with the dorsal black lines. On segment 13, these transverse dashes are very

faint. On segments 5-1 1, between the dorsal tufts is an elongate black spot, with its long axis lateral. On segments 3 and 13, this black spot is quadrate, with long axis lengthwise. Subdorsally on segments 5-1 1, a broad, black interrupted band, its sections on the posterior part of joint 6 and anterior part of 7, forming a subquadrate spot ; in the middle over the incisure is a white spot. An irregular, broken black subdorsal line passes over segments 3-5. An irregular, broken, black substigmatal line on segments 2-5, and on anterior half of segment 6. On posterior half of each segment an irregular, quadrate chestnut - colored, almost ferruginous spot, concolorous with abdominal feet. On the anterior half a similar, more triangular rusty spot. A black spot between ferruginous ones, dotted whitish. Each segment from 5-9, across the stigmatal line, is obliquely crossed on anterior part of each joint by two heavy white lines, enclosing a black dash. On posterior part of the segment from bunch of spines to incisure, is a narrow white line. The lateral parts of segments 2-5, below stigmatal tufts are sooty. Segments 2-6 has a substigmatal bunch of small, whitish spines, thus giving each joint 8 bunches. Segments 7-10, each has 6 spinose tufts or bunches. Segment 1 1 has 8 such tufts. Seg- ment 12 has 7 tufts, the largest dorsally, and segment 13 has 5 tufts, the central one a little below subdorsal tufts, and of same length as the substigmatal tufts. Shafts all black. Lower third of each spinose tuft white, upper part black. Dorsal tufts of segments 2 and 3 are the longest, from 7-8 mm. Tufts of segment 13 are 7 mm. long. Stig- mata light buff. Thoracic feet ferruginous and black. Abdominal legs blackish-brown, the feet ferruginous, covered by fine white hair. Abdominal parts brownish-red, enclosing a longitudinal whitish line. Supra-anal plate shining black above, edged white below and reddish- brown between white lines. Two white dashes on a line with sub- dorsal tufts of segment 13. Upper part of clasper black, below ferru- ginous, covered by fine white hair.

The largest larva measured in length at rest 43 mm., and in motion 48 mm. Width Gj^ miii- Occiputal part of head greenish. A tri- angular greenish depression on clypeus. A greenish stripe passes ob- liquely across the face and nearly meets at triangle of the clypeus. Mouth-parts reddish. Above maxillary a transverse whitish bar. An- tennae reddish and white at base. The ground color of dorsal and lateral parts is made up of alternate, narrow longitudinal stripes of lavender and white, separated by black lines. On dorsum a lavender

stripe, bordered by a subdorsal white one. Then a very narrow laven- der stripe on a line with right and left row of dorsal tuft of spines. Next another white stripe followed by a substigmatal stripe, as broad as the one on dorsum. This is bordered by an irregular, alternate single and double white infrastigmatal stripe. This stripe is double on the anterior part of each segment, and passes obliquely downward

toward the legs.

The lower part of shafts greenish white, terminal end black, sur- mounted by a black spine and seta. The longest shafts on segments 2 z and 13, are two-thirds black on top and greenish-white at the blse Lower two-thirds of all the spines of the tufts greenish-white, almost pea-green in tint, and tips of the upper and topmost spines black The transverse black spot on dorsum of segments 5-1 1, sur- rounded by a pinkish tint. Spiracles cream-colored. Infraspiracular parts alternately marked by red and black patches, minutely dotted white A broad black band across upper part of abdominal legs, red below and dotted white. Clasping surface red. Thoracic feet red and black. Abdominal parts reddish and finely dotted white, and a yellowish longitudinal stripe passing over all segments. Anal plate black and reddish, dotted white, the clasper reddish. Thoracic and abdominal feet covered by fine white hair.

Near Prescott I found this beautiful larva at an altitude of 5,400 feet and up to a little over 6,000 feet. The food-plants were Qncra^s undrdata; Ceanothusfendleri; a white-flowered, prickly bush bearing red berries, Cercocarpus parvifoUus, or Mountain Mahogany, a small shrub from 2-15 feet high, the bark of which is aromatic like wmter- green • and in southern Arizona, of Huachuca Mts., found a few larva. on Quercus emoryii or Black-jack Oak, which bears edible acorns. One larva was found on Opuntia spec, in Yavapai County.

PROCEEDINGS OF THE NEW YORK ENTOMO- LOGICAL SOCIETY.

Meetini; of March 7, 1899.

Held at the American Museum of Natural History.

President Love in the chair. Seven members present.

Dr. Ottolengui read a paper on Collecting in the Woods of Maine, illustrated by a series of photographs of the region. He stated that few noctuids were taken at sugar and light, but Geometrid^e were more abundant, and of which he took about 200 specimens, representing 25 species. After discussion adjournment.

Meehni; (IF March 21, 1S99. Held at the American Museum of Natural History. President Love in the chair. Nine members present.

On motion it was proposed that Dr. R. Ottolengui be nominated as a candidate for the approjniation of $^0 from the John Strong Newberry fund for scientific re- searches.

Mr. Beutenmiiller spoke on TrocJiiUuin {::= ^Egeria) //^/(//c' and allied species. He stated that tibiale was found from Canada, New Hampshire and northern New York westward to Vancouver Island and T. apiforviis occurred as far west as Ne- vada. He pointed out the differences of the two species. They differ mainly in the bands on the abdomen and the markings on the thorax. T. pacificum has the abdo. men wholly yellow, except the basal segments. He also exhibited a .specimen ol Al- catho? caiidata var. 7valkeri and the types of the Sesiidaj described by T. W. Harris- Mr. Shoemaker exhibited a number of rare noctuids taken by him at sugar on

Long Island.

Meetini; of Ai'RiL 4, 1899.

Held at the American Museum of Natural History.

In the absence of the President and Vice-President, Rev. J. L. Zabriskie was elected to act as chairman pro tern. Seven members present.

Rev. Zabriskie spoke on the stridulating organ of Le7na tnlitteata, supplemented by specimens shown under the microscope, and blackboard drawings. The organ consists of a plate situated at the b.ise of the pygidium and furnished with transverse elevated ridges. The sound is produced by rubbing the pygidium against the under- side of the elytra, which is furnished with pointed elevations like the teeth of a file. Mention was also made of the stridulating organs of some Orthoptera. After discus- sion adjournment.

Meeting of May 16, 1899.

Held at the American Museum of Natural History.

President Love in the chair. Nine members present.

Mr. Beutenmiiller proposed Dr. D. M. Cammann for active membership.

It was proposed that a field meeting be held on May 27th-29th to the Ramapo Mts., N. Y.

Mr. Beutenmiiller spoke on Notolophus inornatus, described jjy him some years ago from a worn example, and was placed as a synonym of leiicostigma by Dr. Dyar.

Sept. 1900.] Proceedings of the Society. 20 T

During a short trip to St. Augustine, Fla., last April he took at the light-house on Anastasia Island a number of larvae of itiornains from which he bred three males and a number of females. The species is without doubt distinct. It differs from leuco- stigtna by having ochreous shades on the forewings and by the absence of the white spot. The egg mass is similar to that of definitus, and is not covered with white frothy substances as in leucostigma. Most of the larvae were silvery gray, though a few were dirty yellow. Orgvia falcata Schaus, from Mexico, may prove to be the same as inornatus. Mr. Schaffer exhibited a specimen of Psilopyga from Arizona new to our fauna and which he thought was identical with P. fasciata from Mexico. It differs only from the description of that species in the less extent of the red fascia of the elytra. He also showed Amphiouycha flammata and Pogonochcrus subhama- tus ; Eleitsis pallida and the closely allied Triga picipennis.

Meeting of June 6, 1S99.

Dr. Cammann was elected an active member.

An invitation of the P'eldman Society of Philadelphia to participate at a field meeting on July 4th at Anglesea was received and accepted with thanks.

Dr. Ottolengui showed a large series of Pliisia, calling attention to many rare species of this genus of which he is making a specialty. He also exhibited many other fine species from his collection.'

Meeting of October 3, 1899.

Held at the American Museum of Natural History.

President Love in the chair. Seven members present.

Messrs. George Franck, Richard Stutz and Miss M. E. Valpey were proposed for active membership.

Mr. Joutel exhibited the pupa of Fenesica fanjniiiiii's and the larv;B of Scepsis fulvicollis.

He also recorded the occurrence of Crioccris ij-ptiiiclata on Long Island, N. Y., and the capture of Callida punctata in Bronx Park, New York city ; the latter .species was also taken by Mr. Shoemaker on Long Island.

Dr. Love showed specimens of Ommatostola lintneri taken at Angelsea, N. J. He stated that Prof. J. B. Smith and himself had taken about forty specimens of this species and remarked that it was very unusual to find it in such quantity.

Meeting ok Octoi;er 17, 1899.

Held at the American Museum of Natural History.

President Love in the chair. Eight members present.

Messrs. George Franck and Richard Stutz, were elected active members.

Mr. Beutenmiiller stated that he had taken Schiiiia brcvis in Mosholu, N. Y. , on the flowers of a blue aster. The insect when at rest selects the center of the flower, which color it very much resembles, making it somewhat difficult to detect the moth. He also spoke on the Peach -borer {Sanninoidea exitiosa') and its varieties. He stated that the species was named Zyg(Ena persiccE by Barton in 1807, but was unable to find a published record of the description of this insect under this name.

208 Journal New York Entomological Society. [Voi. viii.

Mr. Joutel exhibited a (cw [lieces of wood, showing the damages done by the white ant.

Mr. Scliaeffer spoke on some species of Cychrtis and stated that it was difficult to separate the females of certain species. In a large series of Cychnis [andrewsii and ri(ii)igsii) from North Carolina he said he was able to separate the males by the structure of the anterior tarsi, but failed to find any constant characters to separate the females. The form he took to be lii/I/i^sii agreed very well with the description of this species, except in size ; it being of the same size, form and color as a)idrc7usji, differing only by the narrow dilated front tarsi of the male. He also spoke on Lcbia fiircata and vittata. He thought that they were one and the same species, there being nothing in the descriptions of these two .species to sejxarate them, except the different form of the sutural and lateral vitta;. A series of specimens from the museum collection were shown with intermediate forms connecting the two species in question. A number of L. depicta from Wyoming were also shown and which differ only from some L.furcata by the entirely black legs. L. pectita ■ittxws to be very constant; in all the specimens seen no variation was observed.

Meeting of November 21, 1S99.

Held at the American Museum of Natural History.

President Love in the chair. Fifteen members and nine visitors present.

Mr. Beutenmiiller exhibited a series of lantern slides of Lepidoptera and their transformations, in their natural attitudes and called attention to the importance of using the camera in the study of the habits of insects. About loo slides were shown.

After discussion adjournment.

Meeting of December 5, 1S99.

Held at the American Museum of Natural History.

President Love in the chair. Nine members and three visitors present.

Mr. Beutenmiiller proposed Mr. W. P. Comstock for active membership.

Mr. Kearfott called attention to a trap for catching Noctuids. He also exhibited a box of rare Mexican Noctuids. Mrs. Slo.sson presented to the Society a lot of Florida Lepidoptera, to be .sold for the lienefit of the Journal. A vote of thanks was extended to Mrs. Slosson for the generous donation.

Meeting of December 19, 1S99.

Held at the American Museum of Natural History.

President Love in the chair. Ten members and four visitors present.

Mr. Comstock was elected an active member of the Society.

Professor John B. Smith spoke on "Underground Insects" and the method of studying them by means of plaster casts. The life-history of two bees was selected and the digging habits shown in some detail. Collctes coDipacta appears in spring and digs down from 24-40 inches before it makes a cell, another is started a few inches higher up, and the lower one is filled up by the sand, taken out the upper. A third and sometimes a fourth are made above that and all are filled up so that the young bees must dig through from 23-40 inches of sand to get to the surface. Ango- chlora humeralis makes clusters of cells and hatches out in midsummer, the females only hibernating. Their borings extend sometimes over five feet below the surface.

Sept. 1900.] Proceedings of the Society. 200

The casts were made by pouring plaster-paris in the entrance of the channel, the plaster being liquid enough to allow the same to flow down into the various cells. After the plaster becoming sufficiently hard a pit was dug some distance away from the nest and gradually the soil was removed towards the channel until the same was exposed on the side wall of the pit ; they were ready for removal. It was illustrated by about 40 lantern-slides, showing the insects and the various kinds of cells made

by these species.

A vote of thanks was extended to Professor Smith for his interesting paper.

Messrs. Kearfott, Davis and Miinch were appointed as a committee to nominate officers for the following year.

Meeting of January 2, 1900.

Held at the American Museum of Natural History.

Eight members present and Prof. J. B. Smith and Dr. Herman Strecker as vis-

' """'xhe committee on nominations appointed at the last meeting proposed the follow- ing officers for the year 1900 : President, Wm. Beutenmuller ; Vice-President, Chas. Palm • Treasurer, L. H. Joutel ; Recording Secretary, Chas. Schaeffer ; Correspond- ing Secretary, Ernest Shoemaker ; Executive Committee : E. G. Love, J. L. Zabris- kie, H. Hug, R. Ottolengui and E. Shoemaker ; Publication Committee ; Wm. Beu- ten'miiller, L. H. Joutel, C. Schaeff"er and E. G. Love.

On motion, which was duly seconded and carried, the Recording Secretary was instructed to cast an affirmative ballot for the election of the officers as nominated, upon which they were declared elected.

Mr Bird read a paper on Oviposition in the Hydreecia and gave his experience in finding the larv.x- of the species. They bore in stems and roots of various kmds of plants and are concealed entirely. To find them is very difficult for the inexperienced, but a close examination of a suspiciously broken twig, a withering stem, or a knotty swelling might result in finding a Hydracia larva. Before pupating some make an exit opportune for the moth, while others leave their burrows and change in the ground. The mode of oviposition of H. riitila which he observed were described. With the antenna, in constant motion in every crack and crevice that may furnish a proper shelter an egg is deposited. The oviposition did not continue after the third night and the number of eggs was about one hundred. H. impecuniosa places the eggs in a greater or lesser number at one point. H. cataphrada has the same habit as H. rutila. The early stages of four SY>tdts—margin{dens, rutila, impecuniosa and cerus ■ sata not known before were observed by him.

Dr. Ottolengui spoke on the genus Calocampa. He called attention to the im- portance of the study of the genitalia in defining the species.

All the known species were exhibited as well as drawings and microscopic slides of the male genitalia.

After discussion adjournment.

A TROPICAL TYPE OF ACRIDIAN NEW TO THE UNITED STATES.

By Samuel H. Scudder.

Professor T. D. A. Cockerell sent me last May from New Mexico a pair of Acridians of a type wholly new to me, apparently belonging to a new genus, and even forming a group apart, intermediate between the tropical American Aleuas and Vilernre in that the fastigium of the vertex is deeply channeled and the hind femora are slender with the superior carina smooth ; unlike the species in both these groups the tegmina are abbreviated and lateral. Unfortunately I have few species of either of these groups with which to compare it and must depend largely upon the tables and diagnoses of Stal and Brunner. It bears a superficial resemblance to a Pyrgomorphid, but is a true Acridian. The genus and species are described below.

Clematodes (/cx-^;/,a, sloo'^), gen. nov.

Body elongate. Head porrect ; face oblique, bent inward, the deeply channeled fastigium of the vertex protruding beyond the eye by more than half ( J* ) or nearly the whole of ( J ) the width of the eye, paraboloid in front, with large triangular, some- what elongate lateral foveolse, facing upward and outward, their plane at right angles with the tempora, the inner margin arcuate; frontal costa narrow, subequal, deeply sulcate with carinate margins, percurrent, widening a little below ; lateral carinse of the face prominent, scarcely divergent below ; eyes rather large, prominent, espe- cially in the male, ovate, oblique or obliquely subvertical ; antennae stout and thick, not so long as head and pronotum together, tapering (especially in female) from base to a rather blunt apex, triquetral nearly throughout, punctate. Pronotum compressed- cylindrical, feebly enlarging from in front backward, multicarinate, the front margin slightly raised to embrace the head, the hind margin distinctly and angularly eniar- ginate, the lateral lobes considerably longer than deep, with nearly straight and nearly horizontal lower margin, and roundly continuous with the disk ; prozona nearly ( 9 ) or quite { $ ) twice as long as metazona, the sulci distinct and percur- rent, the anterior sulcus crossing only the disk. Prosternal spine moderate, tri-

quetral, blunt, especially in female; niesosternal lobes subquadrate, rounded at inner apical margin, separated by their own width ( 9 ) or by less than that {$ ); meta- sternal lobes subattingent ( ^ ) or distinctly separated ( 9 )• Tegmina slender lanceo- late, lateral, with prominent longitudinal veins, reaching the third abdominal seg- ment. Fore and middle legs rather short ; hind legs long and rather slender, the hind femora tapering very regularly, not very strongly compressed, with smooth superior carina and bluntly acuminate genicular lobes, angulate mesially beneath ; hind tibire pilose, with 8-9 spines on either margin, the apical spine wanting on the outer side, the margins rounded. Abdomen compressed, elongate, tapering, multi- carinate.

Clematodes larrese (Cod-, sp.), sp. nov.

Gray of the exact tint of the stems of Larrea on which it was found, the gray everywhere made up of black and white marbling in little long oval patches largely lost in desiccation, pallid beneath ; eyes with the same marbling in life ; after death the whole becomes fuscous, irregularly and feelily mottled with testaceous, all the elevated parts black. Fastigium of vertex carinate in front, the vertex also with a median carina which extends forward nearly to the front border of the eyes, and is bordered by a smooth space, and this by a heavily punctate band posterior to the hinder extremity of the lateral carinate margins of the fastigium, which are just above the middle of the eyes. Pronotum rugose by longitudinal ruga: in which a median carina is easily distinguishable and a number of broken subordinate carina;, both on disk and lateral lobes. Tegmina extending to just beyond the base of the hind legs. Hind femora extending posteriorly a little beyond tip of abdomen, mottled and with obscure fuscous fasciation, the lighter colors principally above, the inferior sulcus bright crimsQU ( 9 )» or orange ( ^ ), the latter fading to luteous after death.

Length of body, ^ , 21 mm., 9> 37 umi-i antenna?, ^, 7 mm., 9; S mm.; hind femora, J*, 12 mm., 9' '5 mm.

I ^,1 9, Messilla Park, N. Mex., May 22, T. D. A. Cockerell.

'* I was yesterday afternoon," writes Mr. Cockerell, "on my back under a Larrea bush, watching the great red-eyed bees visit the flow- ers. As I looked up it gradually dawned upon me that there was something Orthopterous on one of the Larrea stems, and taking hold of it, it proved to be a (? and 9 in copulation of a species of Acridiinte exactly mimicking in color the stems of the Larrea. This was par- ticularly interesting, as we have already Bootettix argeiitatiis con- fined to the Larrea (Bruner gives the food plant wrong) and exactly resembling the foliage ; and now here is a species like the stems."

I have introduced into my description the notes on the color of the living insect given me by Mr. Cockerell in a brief description of the species, and have adopted his specific name.

NEW AMERICAN TINEINA.

By August Busck.

U. S. Department of Agricidliire, Washington, D. C.

In the present unsatisfactory state of our knowledge of American Tineina it is of little value (or worse) to describe promiscuously new species from collected material, difficult of subsecjuent recognition. No one is any the better off because he learns that such and such a new species of Geleciiia or LitJiocoIletis has been taken in such and such a locality. Only when working up a group, either faunistic, or preferably systematic, does it seem to me excusable at present to de- scribe more species, which are known from the type specimen only. Exceptions may be made in the case of new generic forms or espe- cially striking or otherwise interesting species. I believe anyone will endorse this view who has tried to grope through Chambers' flood of descriptions, many of which represent only valueless names, a dead weight on our lists, and which will not for a long time, if ever again, be connected with the species they represent. But as it will take years before the American Tineina fauna can be worked up systematically by groups, which is the end for which we should strive, it does not seem desirable in the meanwhile to withhold from publication new forms, of which the life history has been ascertained and which are of such interest as to be of some positive gain to our knowledge.

And here I might point out an opportunity for any student, who has not the facilities or the desire to do systematic work, but who still

Dec. 1900.] BuscK : New Species of Tineina. 235

has time and desire to add truly valuable contributions to science — namely the working out of life histories of these charming little wonders. The opportunity is open to anyone who has eyes to see and leisure time to spare in fields and woods.

I will be glad to determine any bred material sent to me and to assist with any other information on the subject, within my reach.

That there is enough to do for many observers is shown by the fact that of the 1,200 species, described from this country, the life histor- ies of only a small percentage are known, and that in the District of Col- umbia, where comparatively much collecting has been done, on an average every tenth specimen collected during the last three years rep- resents an undescribed species.

The following are a few species only out of a large collection of bred material on hand, the notes on which I hope from time to time to get in shape for publication.

I am indebted to Dr. Edw. Meyrick, of England, for notes on the new genera, characterized in this paper. I sent him material of these supposed new genera, and he has kindly informed me, that he is not acquainted with any such generic forms from Europe or Australia.

GELECHIID.^. Polyhymno acaciella, sp. nov. (Plate IX, Fig. i.)

Antenna dark mouse gray, white at base. Labial palpi whitish above, dark gray below (that is in front). Face and head white. Thorax white with four longi- tudinal dark mouse-brown stripes. Fore wings elongate, caudate, dark mouse brown; in the middle of the wing from base to beyond end of cell a broad spindle-shaped longitudinal white band ; between this and the dorsal edge is a short white longi- tudinal streak beginning about the middle of the wing and becoming narrower and fainter outwards, loosing itself in the dorsal cilise. At the end of the central white band are three white streaks, one below and two above, converging towards a com- mon point just before apex, in the costal cilia are three short nearly perpendicular streaks converging towards the same point, which is of a somewhat lighter yellowish gray color, than the rest of the wing. Apical cilia white with black tips and a trans- verse dark streak above the produced tips of the wing, while below it is white with gray tips and two very distinct deep black round dots one above the other at base. Dorsal cilia light yellowish gray. Hind wing dark gray; cilia with a golden sheen ; abdomen dark gray, anal tuft yellowish. Alar expanse 1 2. 5-14 ram.

U. S. National Museum, type no. 5353.

Co-type in Lord Walsingham's collection.

236 Journal New York Entomological Society. [Voi. viii.

Described from six specimens reared by Mr. Th. Pergande from A cacia fa rnesiana .

The larva, which is very dark, nearly black, with black head, was found by Mr. E. A. Schwarz to web up and feed between the leaves of the above tree in the streets of San Diego, Texas.

The moth, while easily distinguished from the smaller lighter golden type of the genus Ititeostrigella Cham., is still very close to it in general appearance and in habit.

The food plant oi P. hifeostrigella Cham, is Cassia chai/iiTcrisfa, on which the larva, which is difficult to detect, spins together the leaf- lets. I have reared this species repeatedly in the District of Columbia in late July and early Aiigust.

The only other described species of this genus from the American continent is P. sexstrigella Cham. A much smaller species, diverging considerably from the two others in coloration, but agreeing well gen- erically. Lord Walsingham's three West Indian species are evidently quite distinct from any of the continental forms. Judging from the description and figure, acaciella Busck seems to resemble most Poly- hymno cleoiioreUa\^2\%\x\.^z.vi\, described from Africa.

Neither Chambers' nor Walsingham's delineation of the wing of hitcosingella (Journ. Cin. Soc. Nat. Hist., Vol. II, i8So, Plate III, Fig. 26, and Trans. Ent. Soc. Lond., 1S91, Plate VH, Fig. 78) is very good, and gives no true idea of this elegant form. Chambers' venation is wrong, even with his MS. correction, published by Mr. Beutenmiiller, and Walsingham's figure does not show the caudate apex sufficiently. Fig. i, Plate IX, is drawn from P. acaciella, but is identical in venation and form with the wing of T'. luleostrigella Chzxa.

Tridonella pergandeella, sp. nov. (Plate IX, Fig. 2.)

Antenn;i; purplish black, with two silvery white, thin, longitudinal lines from base to tip. Labial palpi black, second joint with four longitudinal thin silvery white lines, terminal with one longitudinal white line in front. Tongue thinly scaled, white. Face and head brownish black with a thin white line over the eyes. Thorax clear light golden brown concolorous with basal part of fore wings. Abdomen pur- plish black. Fore wings, basal half light yellow brown with a small black, white-edged dot on the middle of the cell. The brown color extends along the costa into the apical half of the wing, the ground color of which is purplish black, edged towards the brown part by a thin white line. In the black part of the wing are scattered sparse white scales segregating into a whitish spot near tornus ; basal part of cilia black sprinkled with white scales, tips of cilia mouse gray. Hind wings purplish gray, darker towards the tip ; cilia brownish. The venation of the hind wing shows more variation than is generally found within a species. Whiie veins 3 and 4 are always stalked and 5 always out of this stalk, the relative length of the branches and the stalk is very variable. Legs purplish black, cox?s sprinkled with silvery scales ; hind tibiie with one broad silvery annulation and with the outer spurs silvery white, inner spurs black ; tarsi with indistinct silvery annulations. Alar expanse 14 mm.

Habitat : District of Columbia.

U. S. National Museum, type no. 5354. Cotypes in the colloc- tions of Dr. Meyrick, and Lord Walsingham, England, Dr. Dietz, Miss Murtfeldt and Professor Fernald. Described from many bred speci- mens. The larva feeds on the common tick-trefoil, Mcibomia {^Des- modiuDi) dillenii.

The eggs are laid singly on the underside of a leaflet and the larva lives in a roomy inclosure between two leaflets spun together. When full grown it is about 12 mm. long, cylindrical, slightly depressed and tapering fore and back. Legs normal ; head is yellow with a black spot over the eye and one on top ; body black marked with yellow as follows : Anterior half of first thoracic joint ; a continuous dorsal spot and two lateral spots on second and third thoracic segments ; two small dorsal dots on segments 5, 6 and 7 (counting head as first joint); joints 8 and 9 have the same two dorsal spots larger and more con- spicuous besides two lateral spots, one on each side. End of body all black ; entire body clothed with rather short sparse white hairs.

Dr. Dyar has given me the following description :

" Head rounded, elongate, the lobes full ; clypeus high, the paraclypeal pieces narrowly reaching the vertical triangle ; labrum longer than wide, projecting, emarginate ; surface shagreened ; setse pale, some long, others short ; pale luteous, a black patch at top of lobe next suture, and a broad blotch on the lower angle of cheek behind ocelli ; ocelli weak, in a black p tch ; antenna; moderate, pale. Thoracic feet large ; abdominal ones small, slender, normal, the crochets in a com- plete small circle, smaller and almost broken on the outer side ; in a single row on the

anal feet, the posterior half of the circle being obsolete. Cervical shield rectangular, the posterior angles rounded, bisected on dorsal line, complete as to its sette ; not strongly cornified, pale, a large black patch on posterior lateral angle and a small one on anterior angle. Tubercles normal, distinct, brown-black, with rather long pale setK. On thorax ia and ib well separated, iia -|- iib, iv -|- v ; on abdomen, i dorsad to ii, iv and v in line, remote, vi normal, vii of three setce in a nearly straight line on a common elongate tubercle, viii normal. Feet surrounded by black, chitinous ring- .shields. Skin smooth, blackish ; a pale yellowish patch about tubercle i, large on joints 3, 4, 8 and g, small on the others, absent on il ; a lateral patch about tubercle iii, large on joints 2, 3, 4, 8, 9 and 12, small on the others ; smaller patches about iv and v and before vi on joints 3, 4, 8, 9 and 12. Anal flap blackish, paler centrally, not cornified." — Harrison G. Dyar.

When younger, the larva is of a much lighter appearance, the yellow predominating. It is very agile and runs quickly forwards or back- wards and lets itself fall on a silken thread, if the leaves are not care- fully handled. When ready to pupate it enlarges its cell by adding the third leaflet, and suspended by a slight web a thin white half- transparent oval cocoon is spun inside the cell, in which the larva transforms to a rather robust light brown pupa.

There are two or three overlapping generations yearly in this lo- cality, the moth issuing late in June and late in August and sometimes again late in September

The species over-winter as imago. The imago is very retired in its habits and is not taken at light.

I believe this species is very local ; I have reared the moth in numbers for three successive years, but all taken within a limited area on the eastern side of the eastern branch of the Potomac River. Al- though the food-plant is common everywhere I have, though diligently seeking, never found it elsewhere, not even iii other parts of the Dis- trict of Columbia apparently similar in nature. I have not seen a single specimen in any of the collections except those reared by myself. Neither had Miss Murtfeldt, Dr. Dietz or Professor Fernald ever met with it, and such a conspicuously marked insect would be likely to be remembered if once met with.

I have named this, the first Tineid I ever reared, in honor of my friend and teacher Mr. Th. Pergande, under whose guidance I have had the good fortune to be initiated into the closer study of insect life in the field and in the insectary.

Triclonella villella, sp. nov.

Described from a single female reared by Mr. Pergande accidentally from Xolisma {Ain/nviieda) ligustriiia, collected at Cabin John, Md., for another pur])ose.

Larva not observed and food-plant therefore not absolutely certain. The species has somewhat narrower fore wings than the type of the genus but agrees in all respects with the generic description and is clearly closely related io pcroandce//a.

Euclemensia schwarziella, sp. nov. (Plate IX, Fig. 3.)

AntennK bluish metallic black. Labial palpi light silvery strawcolored with tips darker. Head and thorax deep bluish metallic black. Fore wing bluish black with strong metallic reflections. At basal third is a transverse irregular fingered bright red or golden fascia, narrow in the middle, broadening out in one outwards and two inwards lobes or fingers at costal and dorsal edge. At the middle of the wing on costal edge are a few silvery white scales ; at the beginning of the costal cilia is a large white dash, edged below by a red spot, and at the beginning of the dorsal cilia is another white spot, edged above with red. The shade of the red on the wing varies in different specimens, as is the case in E. bassettella Clem, from a nearly golden yel- low to a rich deep red. Hind wing purplish black. Abdomen bluish metallic black '■> legs metallic black ; hind tibi?e with two silvery annulations, one at the middle and one at the end, and with spurs silvery white. Alar expanse II-I2 mm.

Habitat : Santa Rita Mountains, Arizona.

U. S. National Museum, type no. 5356.

Described from six specimens, collected by Mr. E. A. Schwarz and reared from a kermes species on oak sent by him. The moth is- sued in June through a sharply cut circular hole, the lid of which still adheres to the kermes.

This species has the same colors as, but a very distinct pattern from the common E. bassettella Clem. The generic characters are identical.

I name this beautiful species in honor of the collector, who has added many new and interesting species to the material in the U. S. National Museum.

ELACHISTID^. Scelorthus, gen nov.

Hind wings under I, lanceolate, 6 veins, 3 and 4 absent, cell open, 5 and 6 stalked from independent stem, 7 independent. Hind tibice smooth with two groups of long, stiff bristles above the spurs, one at the middle, the other at the end. At rest the hind legs are stretched upwards above the wings.

Type : ^. pispniella Bu.sck.

This genus resembles very much Lifliariaptoyx, Chambers (Can. Ent., VoL VIII, p. 217, 1876), in head, wing form, venation and gen- eral habitus ; but it is distinguished at once by the two groups of stiff bristles on posterior tibiae and differs also in the forewing by having vein lb distinctly and greatly furcate at base while in the hindwing the submedian vein is simple.

Scelorthus pisoniella, sp. nov. (Plate IX, Fig. 4.)

Antenna; metallic black. Labial palpi purplish white. Face silvery. Head and thorax shining greenish aureous. Fore wing purplish gray with blue and silvery re- flections. At base is a dorsal aureous patch and at the middle of the wing is a nar- row transverse aureous fascia ; at basal fourth is a small black costal dot, surrounded by metallic purple scales. Cilia dark ashy gray. Hind wings silvery gray becoming darker outwards towards the top where they are shining purplish black. Cilia with a golden sheen. Abdomen above metallic purplish black, below silvery white. Sides of thorax below the wings golden. All coxa^ silvery white, tibia" and tarsi purple ; spurs and spines on hind tibia? black. Alar expanse 8.5 mm.

U. S. National Museum, type no. 5357. Cotype in collection of Dr. Meyrick, England.

Described from four specimens, bred in February from Pisonia ob- tiisata, collected by Dr. Harrison G. Dyar.

The moth is a shining, elegant little form, related to and remind- ing one of Heliodines. The following are Dr. Dyar's notes on the larva :

"The larva lives on the leaves of Pisonia obti/sata, at first mining between the upper and lower epidermes, later eating little patches on the back of the leaf through to the upper epidermis from a position in a central white web, covered by a lump of frass which adheres to the web. In one instance the larvae were found on Pisonia aculeata with the same habits.

" Slender, monilifomi, joint 13 narrower ; transparent whitish-green, tubercles represented by tiny black dots. Head flattish, the clypeus high, nearly touching the vertical triangle ; whitish, ocelli black, mouth pale brown. Tubercles i and ii are in

Dorsal vessel slightly darker than the rest of the body ; $ glands colorless. Later darkish green, the dorsal tubercles purplish-black. On the thorax tubercles la and lb are separate, la small; one tubercle representing ii, one representing iv -f- v, but only one hair seen on each distinctly, the other minute. Pupa in the web, flat and wing-margined, green with diffuse brown-black dorsal stripe on the abdomen." — (Harrison G. Dyar. )

Lamprolophus, gen. nov.

Antennte j^ slightly serrate. Labial palpi very short, straight, pointed, droop- ing. Maxillary palpi obsolete. Tongue long, naked, spiraled. Fore wing elongate, ovate pointed, apex produced and deflexed, termen sinuate ; with raised scale tufts ; II veins, 8 absent, all separate, 7 to costa, lb simple. Hind wing lanceolate, 7 veins, 4 absent, cell open, 6 and 7 stalked, 5 from independent indistinct stem 2 and 3 stalked. Posterior tibite with a row of short stiff hairs above.

Type : L. litJiella Busck. Lamprolophus lithella, sp. nov. (Plate IX, Fig. 5.)

Antenna; dark metallic purple. Labial palpi golden yellowish. Face, head and thorax shining black with strong metallic green and purple reflections. Fore wing, ground color deep metallic purple with strong golden reflections, on the middle half of the wing are four equidistant costal raised scale tufts and intermediate between these are three dorsal scale tufts all strongly metallic silvery or golden bluish. At the base is a dorsal golden yellow patch ; just before the last two scale tufts are a costal and a dorsal golden yellow spot and in the apical part of the wing are two par- allel longitudinal golden yellow streaks. Cilia purplish gray.

The golden reflections of the wing make a realization of the true colors difficult ; in some lights the wing looks all golden, in others all silvery bluish. Hind wing silvery at base and along costa, outer half purplish black ; cilia dark purple. Ab- domen dark metallic purple above, below light golden or silvery according to the light. Legs golden purple with a narrow white bar at the end of the posterior tibia; and with all spurs light silvery. Alar expanse 9 mm.

Habitat: Palm Beach, Florida.

U. S. National Museum, type no. 5358. Co-types in the collection of Dr. Meyrick, England. Described from four specimens bred in February from Pisoiiia aciileata. The following are Dr. Dyar's notes on the larva :

" The larva bores in the young stems of Pisoiiia aciileata. It spins a slight web above the base of a young leaf and enters the stem, leav- ing a round hole from which the frass is ejected.

" Cylindrical, the segments short and rather thick, faintly 2-annulate. Translucent sordid whitish, no marks. Tracheal line white ; ^ glands dark ochreous. Tubercles small, brown-black, i and ii nearly in line,, iv and v approximate but distinct, iv .slightly dorsad, iii, vi and vii normal. Feet small, pale except the anal pair which are

broadly black ringed. Anal plate large, black ; also extensive black plates on joint 12, single for tubercle i and tubercle ii, paired including tubercles iii to v and the spiracle ; joint 12 is small and hunched up, 13 still smaller, scarcely divided by a suture. Skin slightly shining, minutely granular. Cervical shield elliptical, bisected, black. Head round, free, slightly bilobed, higher than wide, black, shading to brownish below ; clypeus high ; ocelli black. Tubercles ia and ib are separate on joints 3 and 4." — (Harrison G. Dyar. )

HYPONOMEUTID.^^:. Hemerophila dyari, sp. nov. (Plate IX, Fig. 9.)

Antennae nearly three-fourths black with silvery white annulations and with two longitudinal rows of cilia on the underside ; length of cilia twice the thickness of the antenna;. Labial palpi moderate, curved ascending ; second joint long, slightly rough in front, white with one black annulation ; terminal short, thickened, blunt, black, with one ring round the middle and with the extreme tip white. Maxillary palpi obsolete. Tongue well developed, spiraled. Face, head and thorax smooth, very dark olive-green, nearly black, evenly and thickly sprinkled with golden yellow sciles. Basal two-fifths of fore wing concolorous with thorax and equally evenly sprinkled with yellow scales. This basal part is sharply edged by a narrow, somewhat undulating, transverse line of bluish white scales, most pronounced on the costal half of the wing. Outside of this line the wing has a very perceptible but not easily defined purplish sheen. The ground color is the same as in the basal part of the wing, but the more thickly sprinkled light scales are of a purplish white color, which dominates this part of the wing and makes it appear much lighter colored than the basal part. Towards the end of the wing the light scales become gradually fewer and nearly golden yellow again as on basal part of the wing, but the bluish cast remains. Just at apex the triangular corner of the wing is so thickly overlaid with golden scales as to appear all gold ; this part is separated from the other by a deep black narrow line from costal edge to middle of termen. Along the outer edge of the wing runs a deep black line. Cilia dark purplish fuscous with strong metallic blue refiection. Hind wing dark olive-brown, cilia purplish with golden yellow base. Abdomen above deep bluish black, below with a light golden yellow transverse band on each segment. Legs golden with black annulations. Underside of thorax yel- lowish white. The underside of the wings dark olive-brown ; the apical corner of the fore wing, corresponding to the golden upper part, is golden yellow ; along the base of the cilia is a deep black line corresponding to that on the upper side. Alar expanse, 14 mm.

Habitat : Palm Beach, Florida.

U. S. National Museum, type no. 5362.

Described from a single bred male in perfect condition, issued in March.

The venation of this species (Plate IX, P'ig. 9) is as follows: Fore wing tortricid-shaped, 12 veins, all separate, 2 distant from corner of cell, 3-10 from end of cell, 7 to termen, 8 to costa, \b fur-

cate at base, internal vein from between 11 and 10 to between 8 and 7. Hind wing over I triangular, 8 veins, 3 and 4 short-stalked, 5, 6 and 7 parallel.

I take pleasure in naming this beautiful species after its discoverer, Dr. Harrison G. Dyar.

Only one other species of this genus, H. {Siino't/ns^ vicarialis Zel- ler is recorded from North America. This species is unknown to me except from description, but it is evidently entirely different from H. ihari.

The breeding of this species from Ficiis agrees with the known food-habits of other tropical species of the genus as recorded by Meyrick.

The genus Jra/s///x'kamia Riley is very near to Hemerophila, differ- ing principally in the thickened antennre. It agrees perfectly in wing form and venation. The difference in labial palpi is so slight that it is unfortunate that Professor Fernald has used it as a differential character in the synoptic table of his valuable paper on. these and allied genera (Can. Ent., 1900, p. 238). He calls the third segment of the labial palpi in ]]\ilsiii}:;hai)iia long and pointed, while I should decidedly call it short and blunt, very little longer indeed than in Hemcropliila. Long and short are relative terms, susceptible of varying interpretation and therefore I think Professor Fernald' s table would have been im- proved by placing Walsinghamia under the same number as Hemero- pJiila and then using the antennal character to separate.

The common food-plant and peculiar larval habits further confirm the close relationship of these two genera.

The following are Dr. Dyar's notes on the larva :

"The larva lives on the leaves of the rubber banyan tree (^Ficus aurea and F. pediincii/ata). When small, on the back of a leaf under a delicate silken tent ; when large on the upper surface under a similar broad web spun flat on the leaf across the slightly concave upper side. The larva eats holes through to the lower epidermis in a patch about half an inch in diameter under the web. These patches remain even on old leaves, showing the characteristic traces of the larva, though the delicate web is evanescent and disappears almost as soon as the larva quits it. The larvDS are very active, falling to the ground with contortions when disturbed. Each remains in its web only long enough to eat one or two patches, when it proceeds to a new leaf to form a fresh web. They are always solitary at maturity, though sev-

eral may be found in a common web when small and still living on the back of the leaf. Three stages were observed, all similar except in size; widths of head .6, .8, i.i mm."

Head rounded bilobed, clypeus reaching over halfway to vertex, mou h project- ing ; a long dark spinneret ; antennce short, but palpi distinct ; lobes and clypeus bulging, labrum distinctly emarginate ; green, ocelli black, labrum brown edged, setae black ; width I.I mm. Body a little flattened, tapering a little at the anterior end and more so posteriorly; anal feet divergent, projecting, the other abdominal ones short ; thoracic feet large, bent at right angles centrally like claws. Segments 3annulate, the anterior annulet very small. Tubercles small, concolorous, a little elevated; i and ii in line, iv and v united ; on the thorax ia and ib united, iia and iib united and iv and v likewise, all normal. Setse distinct, moderate, pale, but black on the con- colorous and invisible cervical shield and anal plate. Green, clear, uniform, the dorsal vessel darker, feet whitish gi^een. The active and sensitive larva spins its delicate web with great rapidity.

Cocoon a mass of moist silky web on the top of a leaf or other suitable place re- sembling the larval tent, but much larger and containing centrally an imperfect tube with a ribbon of white silk at the top. The pupa is pale green without marks and can wriggle up and down the tubular part of the cocoon, at will." — (Harrison O. Dyar. )

Food-plants : Ficus, spp.

TINEID.E. Leucoptera smilaciella, sp. nov. (Plate IX, Fig. 6.)

Antennre golden white, basal joint enlarged to a considerable eye cap, silvery white. Face smooth, silvery white. Head tufted, silvery white. Labial and maxil- lary palpi obsolete. Thorax and fore wing silvery white ; from middle of costa ob- liquely outwards reaching to the middle of the wing is a golden yellow streak with parallel dark edges ; between this and apex is a triangular golden yellow spot also thinly edged with black ; at tornus is a conspicuous deep black spot followed on the outside by somewhat raised bronzy silvery scales, and on the inside and above sur- rounded by a narrow golden yellow area. Just before apex is a longitudinal short golden yellow streak ; apical cilia white with dark fuscous tips and two tranverse dark fuscous streaks ; dorsal cilia gray. Hind wing dark purplish brown nearly black, cilia a shade lighter. Abdomen dark fuscous above, light silvery fuscous below. Anal tuft white ; legs golden white, posterior tibiae hairy. Alar expanse 7-5-8.5 mm.

Habitat : District of Columbia, Pennsylvania.

U. S. National Museum, type no. 5359. Co-types in collections of Murtfeldt, Fernald, Dietz, Walsingham and Meyrick. Described from many bred specimens.

Food-plant : Sniilax glauca, and S. rofundifolia.

The eggs, which are laid on the underside of a leaf singly, but

Dec. 1900.] BuscK : New Species of Tineina. 245

often 2-5 on one leaf, are oval, glistening white and very large in proportion to the moth.

The young larva eats into the leaf, forming a short, narrow, serpentine track, which soon broadens out in a large irregular upper blotchmine, often entirely obliterating the early part of the mine. The mines show reddish brown on the upper side of the leaf and con- . trast very conspicuously with the dark-green foliage. The black frass is distributed irregularly in the mine, the inside of which is a dirty domicile for such a dainty creature to issue from. The larva is, when full grown, 5.5 mm. long moniliform, somewhat flattened and taper- ing backwards ; first thoracic segments the broadest, nearly twice as wide as the head. Head light brown, body dark, glossy-greenish with two longitudinal black spots on first thoracic segment ; and legs normal. Often two to five larvae are found within a common large mine. Dr. Dyar has made the following notes :

" Head flattened, subcircular, labium slightly projecting, clypeus band-shaped but narrowed above, reaching vertex ; paraclypeal pieces large, broad, each nearly as broad as the clypeus itself, narrowed above, reaching vertex and reducing each lobe to about one-fourth of the surface of the head. Ocelli obsolescent, antennae rudi- mentary Body moniliform, joints 2 and 3 large, 4 and 5 smaller, 6 to li larger, 12 and 13 tapering rapidly, 13 elongate, divided. Feet normal, thoracic ones small abdominal short with a complete, broad ellipse of small, sparse, scarcely recurved crochets ; those of joints 7 to 10 and 13 essentially alike. Whitish, no marks, no shields, but a paired blackish patch in joint 2. Tubercles absent, set.^ very fine and slender practically absent except laterally, iv and v in line remote, iv a trace dorsad ; only iii and iv are at all well developel. On thorax the subprimaries lu and iv are present."— (Harrison G. Dyar.)

When fully grown the larva quits the mine through a moon-shaped cut in the upper epidermis and spins a beautiful glistening white brid-ework, consisting of two paralel broad flat silken bands each about ID mm. long and 1.5 mm. wide, connected at the middle, under which the spindle-shaped snow-white cocoon proper is made.

Several overlapping generations are found during the summer m this locality, the moth issuing from the middle of June to late in Sep- tember. The insect over-winters as imago. Besides two Florida species described by the writer only one other species of this genus is described from this country, namely Leiicoptera {Cemiostoma) albella Chambers, on poplar; but diligent rearing will disclose more unde- scribed species, as I have taken others at light this summer.

It will be seen from the delineation of the venation ^Plate IX,

246 Journal New York Entomological Society. [VoI. viii.

Fig. 6) that this species differs in some respects in the fore wing from that given by Dr. Meyrick as characteristic of the genus ; but the toiit-oiscinble of the insect, the larva and the cocoon is so evidently close to the European forms, that I do not hesitate in placing it in the same genus.

The venation of the present species is : Fore wing, lo veins, 4 and 8 absent, all separate, 7 to costa, ib furcate at base. Hindwing : 6 veins, 3 and 4 absent, cell open between veins 2 and 5.

Tinea oregonella, sp. nov. (Plate IX, Fig. 7.)

Antennfe dark fuscous. Labial palpi brownish, both joints tipped with white. Maxilary palpi very short white. Face and head rough, yellowish white. Fore wing rusty white, somewhat variably marked with dark l)rown, nearly black, longi- tudinal streaks. The two most conspicuous and constant are one on the fold reaching from the base to the apical third of the wing and one in the middle of the wing, reach- ing from basal third to apex. At the base of wing is a costal and a dorsal less con- spicuous streak and along the edge of the wing is a more or less regular row of dark brown spots ; cilia white, dusted with reddish brown. Hind wing dark gray, cilia yellowish. The ground color of the wing varies somewhat in different specimens, being pure dull white in some while in others ii is reddish or brownish ; and with the exception of the two first-mentioned heavy streaks all the other markings are some- times nearly effaced, while in other specimens they are emphasized. Also the color of the streaks is somewhat different in different specimens ranging from brown to pure black. Legs white ; tarsi with black annulations, tuft on hind tibise yellowish. Alar expanse 15-17 mm.

Described from some 300 specimens bred from a large woody Polyporus-like fungus on Redwood, containing about half a cubic foot, collected in Oregon by Dr. H. von Schrenk, and kindly turned over to me by Mr. E. A. Bessey, of the Division of Vegetable Pa- thology, U. S. Dept. of Agriculture.

When I received the fungus many moths had already issued, more than two hundred, in fact, from an actual count of the protruding empty pupa-skins.

I placed the fungus in a covered glass jar and during the following Aveek (late September) more than six hundred more moths issued. The fungus was a curious sight, looking like a strange hedge-hog, with the closely-set projecting empty pupa-skins sticking forth like spines.

Body slender, cylindrical, not tapering ; segments not annulate ; feet normal ; subventral fold rather prominent. The circle of crochets of feet complete ; green, translucent ; dorsum heavily darkly shaded from numerous fine dark red mottled lines, becoming more sparse and dotted towards the ends and only faintly traced on joint 2, which looks green. The dorsal ground color appears as about six fine longitudinal irregular lines. Tubercles small, black ; i dorsad to ii, iv and v in line, approximate but distinct on the subventral fold ; vi distinct ; vii on the leg base, a group of three hairs.

IN MEMORIAM: REV. DR. GEORGE D. HULST.*

By Archibald C. Weeks.

The Rev. Ur. George D. Hulst was stricken with neuralgia of the heart on the morning of November 5, 1900, as he was preparing to visit some sick members of his congregation, and expired ahiiost im- mediately.

Upon arising in the morning he complained of having suffered much pain during the night, and summoned his family physician, who prescribed a simple remedy and remained at the house until it was ob- tained, Dr. Hulst meanwhile genially rallying him upon its potency and character, and apparently as buoyant and animated as usual. After the departure of the physician he sat by the window resting his head upon his hands, and as his daughters came through the hall he rose to speak to them. Hardly had he done so than he sank slowly to the floor, death being instantaneous and as surprising as it was unex- pected. He had never had what might be termed a sick day, and by his lifelong habits of temperance had retained to a remarkable degree his boyish activity and sprightliness. Only the day before, while con- versing with members of his congregation, he had spoken of his excel- lent health.

Dec. 1900.] Weeks: In Memorfam : Rev. Dr. George D. Hulst. 249

Notwithstanding the urgent demands upon his time and endurance by his profession, he was about preparing to summon together his long- known friends and sympathizers in the pursuit of entomology, renew the associations which had been interrupted for several years by his engagements, and toil with undiminished energy toward the comple- tion of his investigations in the branches of that science to which he had particularly devoted himself for a number of years.

Dr. Hulst at the time of his death was the pastor of the South Bushwick Reformed Church, at Bushwick Avenue and Himrod Street, Brooklyn, and had held this position from the beginning of his min- istry, July 4, 1869. An unbroken pastorate extending through so many years would seem to be all the evidence required to prove his worth and the affection and esteem of his congregation for him. But this is not all. Charity and works with him went hand in hand. Every honest seeker after employment received from him a courteous hear- ing and aid to the extent of his power. Over one hundred distressed families were said to have been relieved by him during a period of so-called hard times. The funeral services were held in the church where he had ministered so long, and so large was the attendance that fully one- half of those assembled were unable to gain admission.

He was born in the old Duryea Homestead at the Penny Bridge, Brooklyn, on March 9, 1846, attended Jonesville Academy in Sara- toga County, N. Y. , entered Rutgers College at New Brunswick, N. J., and received in addition to his diploma a gold medal from that insti- tution for his proficiency in the classics. He was graduated from the Theological Seminary in 1869. From his boyhood he had manifested a deep interest in nature, especially in plant and insect life, and this interest, supplemented by painstaking study, had justly raised him to a high rank as a botanist and entomologist. His knowledge and attain- ments in these sciences were always at the service of the public, and the humblest seeker after information received equal courtesy and con- sideration from him.

Notwithstanding the demands of his congregation upon his leisure, and without neglecting his duties to them, he still found opportunity for the exercise of his natural inclinations and talents. He delivered a course of lectures upon entomology at Rutgers College, and for a time acted as State Entomologist of New Jersey; was one of the edi- tors of Entomologica Americana, a publication of the Brooklyn Ento- mological Society, from 1887 to 1889, and served that society as a

250 Journal New York Entomological Society, [Voi. viii.

member in many capacities for a number of years. He was also a member of the New York Entomological Society and a member of the Brooklyn Institute of Arts and Sciences, being President of its Depart- ment of Botany and an officer of its Department of Entomology, and annually delivered lectures before these departments in their respective courses. For twenty years he had been a member and subsequently a Fellow of the American Association for the Advancement of Science, an honor conferred upon him in recognition of his scientific researches and attainments, and for like reason he received from his own College the degree of Doctor of Philosophy. He was one of the first mem- bers of the Holland Society, tracing his descent from the Von Hoist family, who at an early period settled in Brooklyn, and from whose name his own was derived.

It is unnecessary to give in detail a list of Dr. Hulst's numerous contributions to botanical and entomological literature. Many of the latter consist of short papers upon miscellaneous subjects, scattered chiefly through the Bulletin of the Brooklyn Entomological Society, published from 1878 to 1885, Entomologica Americana published from 18S5 to 1890, Journal New York Entomological Society, and the Transactions of the American Entomological Society, in which latter the majority of his descriptions of species appears.

He worked in both macro- and micro-lepidoptera, and described many species in various genera of both divisions. One of his prin- cipal papers is a very complete synopsis of the genus Catocala, pub- lished in the June (1884) number of the Bulletin. He also did much systematic work in the Phycitida^ and Epipaschiina;, but his best efforts seem to have been reserved for the Geometridte, in which family his described species outnumber those of any other author. It had been his ambition to place the knowledge of this intricate and troublesome family upon an orderly and exact basis, and it is to be deeply regretted that he was unable to realize the fruition of his hopes in the cause of entomological learning.

His collection of Geometridce was one of the best, if not the best, in the country. Many of his types were deposited in the Museum of the Brooklyn Institute, but his collection of lepidoptera was some years ago donated and delivered to Rutgers College, Dr. Hulst only retaining in his custody such portion as he required for study and comparison.

His widow, two daughters and one son survive him.

TWO NEW SESIID^.

Bv Wm. Beutenmuller. Sesia mariona, sp. nov.

Female. Head white, vertex pinkish ; collar pale pinkish above, white beneath; palpi white. Antennae black, with a greenish lustre. Thorax green black with a very large bright red patch on each side in front, contiguous with the bright red line on each side above. Abdomen and anal tuft wholly metallic green black. Legs metallic green black, anterior coxcu white. Fore wings metallic green black with a broad, bright red line along the inner margin ; extreme edge of costa pale testaceous or dirty white. Hind wings brown with a violaceous lustre, central part with two transparent areas, the upper one broken by the discal mark. Underside of wings brown with a decided violaceous lustre, costal margins pale testaceous. Expanse, 17-20 mm.

Habitat : Trimble and Pagossa Springs, and Durango, Colorado, July 6, 19 and 30, 1899.

Types : Two females. Coll. Dr. William Barnes, Decatur, Illinois. One female. Coll, Am. Mus. Nat. Hist.

Described from three females. The male and earlier stages of the species are unknown.

Sanninoidea grsefii, var. barnesii, var. nov.

Female. Head, thorax and legs entirely metallic blue-black. Abdomen blue, black, with the fourth segment above orange. Fore wings opaque blue-black. Hind wings transparent with the margin blue-black. Expanse, 28 mm.

Habitat: Clear Creek Cafion, Colorado, August.

Type : Coll. VV. Barnes, Decatur, Illinois. Like the type form, but has the fourth abdominal segment orange above, giving it the aspect of the female oi Sanninoidea exitiosa.
