There occurred in almost all cases one copulation in an hour, no more and no less. This definiteness in time is also observable in the courting and in the copulation, the average time spent being about ten and seven minutes, respectively. The same table also shows the fact that the males do mate with more than one fe- male, to as many as Six. Another very interesting fact observed in this connection is that which pertains to the function of the wings and balancers of the male. Since, as Mr. Gossard* stated, the male rarely takes to flight, the wings of this male scale insect are of more use as the support for the body during the process of copula- tion. In this explanation we see the significance of the pres- ence of a highly modified pair of balancers. The balancers of this insect end each with a hooklet, with which they hold on the wings and strengthen the latter. If the wings are useful for flight only this elaborate process on the balancers may not be necessary. Dipterous insects pos- sess, as we know, a pair of balancers, but with no hooklet. They nevertheless fly as easily as other insects do. The bal- ancers of the cottony maple scale again are lacking in these hooklets. Reasoning thus, I am inclined to believe that the bal- ancers of the cottony cushion scales, whatever their original function might have been, have been so modified as to strength- en the wings during the process of copulation. 8Gossard, H.

CHAMBERLIN, Forest Entomologist, Oregon State Col- lege, Corvallis, Oregon. (Continued from page 139) 44. Polycesta californica Lec. Found throughout the oak region of California, though never common. It has been taken from dead black oak (Quercus kelloggii) in Trinity County, Yosemite Valley and Mariposa County ; also taken from Quercus douglasu. 45. Chrysophana placida Lec. Found throughout the coniferous area of northern Califor- nia and the Sierras, also well distributed over western Oregon, and no doubt extends into Washington, since the writer has taken it 35 miles south of the Columbia River. Dr. Van Dyke has one specimen bred from the cones of P. ponderosa. Mr. Miller, of the Ashland Station, has bred it from the cones of Pinus attenuata. Its common host plant is Douglas fir, but it also breeds in the upper part of small lodge pole, yellow and knob-cone pine, and in the edges of fire scars of Abies concolor and A. magnifica. There are three phases: a striped phase, which is the more common, and is often taken in open fields on flowers in south- ern Oregon; an all-green variety, which occurs at higher ele- vations of the middle and southern Sierras, and which the writer has taken at Corvallis, Oregon; the third variety is un- striped, of a dark bronze or black color, and very scarce. Dr. E. C. Van Dyke, of the University of California, has very kindly furnished me with his own notes on the hosts, etc., of species he has taken in the northern part of the State. I wish, particularly, to express my indebtedness to Dr. Van Dyke for his notes on the genus Acmaeodera; practically all the information on that genus is due to his observations, since I have personally come in contact with but two species, A. vandykei and A. connexa. 46. Acmaeodera angelica Fall. “Generally to be found flying about brush or in the flowers Vol. xxviii] ENTOMOLOGICAL NEWS 167 of Yerba Santa, Erydectylon. Very common in the Sierra Madre range of southern California, but also extends north- ward. I have specimens from the following more northern lo- calities: Mariposa County, Lake County and Lake Tahoe.” 47. A. hepburnii Lec. Very common in most parts of California. Generally to be taken in flowers, such as certain compositae like Baeria and in the flowers of the evening primrose. 48. A. acuta Lec. Perhaps even more common than the preceding and found in similar places, also as widely distributed. There are two phases, the common one, where the markings are broken up, and the other, where definite stripes are formed. 49. A. connexa Lec. “Probably the most common species which we have in the State and widely distributed. Usually found in flowers like the two preceding. I have also dug it out of its pupal cham- bers from the dead branches of oak, Quercus wislizenii, in Marin County, California.” 50. A. labyrinthica Fall. “This is generally a species of southern California. I, how- ever, have specimens from Castella, July, 1912, and from Tuo- lumne County.” 51. A. plagiaticauda Horn. Found throughout the Sierras, but rare. One specimen has been seen from Siskiyou County, California, and another from Lake Tahoe. Breeds in manzanita. 52. A. variegata Lec. This Rocky Mountain and Great Basin species courses into California through the gaps in the mountains north of Mt. Shasta. “I have beaten specimens from the branches of dead yellow pine at Carrville, Trinity County, California, during June, 1913. I believe that it breeds in yellow pine.” 53. A. vandykei Fall. “Found throughout the northern and middle Sierras. It breeds in Ceanothus. I have specimens from McCloud, July, 168 ENTOMOLOGICAL NEWS~ [Apr., 757 1914; Sissons, July 5, 1900 (type material) ; Shasta County and Mariposa County.” This species occurs in southern Ore- gon. ' 54. A, mariposa Horn. “A species of the middle and southern Sierras. I, however, have specimens from Sonoma County and Lake Tahoe and it no doubt extends farther north.” 55. A, dolorosa Fall. “A southern species. I have specimens from Lake and Mariposa Counties, and it probably extends much farther north.” 56. A. hornii Fall. . “Of this Arizona species I have seen what I consider typi- cal specimens from near Placerville, El Dorado County, July, 1906 as well as from Mt. San Jacinto, in southern Cali- fornia. I have also seen a phase in which the marginal patch of yellow is broken up into large blotches (otherwise not dif- ferent) from near Placerville, Siskiyou County, and from Tuo- lumne County.” 57. A. gemina Horn. “This species is widely distributed in the State, though no- where common. It is generally to be found resting on twigs or in flowers, such as those of the wild buckwheat, Eriogonum. I have specimens from Mariposa and El Dorado Counties, and have seen them from much farther to the north. There are two fairly distinct phases, the var. nebulosa Horn, in which the markings are much broken up, and the typical form, in which the markings are of a lineate type. These phases, how- ever, mate indiscriminately and may be found in the same territory.” 58. Agrilus politus Say. Abundant throughout the West. Chiefly found on willow in which it breeds, but also on live oak, the fine twigs of which it often prunes, the larvae girdling the twig within the bark. There is a biue phase (perhaps a distinct species), which seems to be confined to the alder. Vol. xxviii] ENTOMOLOGICAL NEWS 169 59. A. vittaticollis Rand. “One specimen taken by F. W. Nunenmacher in Josephine County, Oregon, May 8, 1910, and two by myself at Carrville, Trinity County, California, July 1, 1913, on willow.” Dr. Van Dyke. 60. A. walsinghami Cr. Type locality, Yreka, California. Others have been taken in same region; also in Inyo County, California. It breeds in one of the desert shrubs. 61. A. nevadensis Horn. ‘ Western Nevada type locality. There are in the Van Dyke collection specimens from the Yosemite Valley taken on pop- lar. It may possibly extend farther north. Notes on some recent studies of Dragonfly Wing Tracheation (Odon.). By J. G. NEEDHAM, Cornell University, Ithaca, New York. It was a fortunate day for the progress of our knowledge of the Odonata when R. J. Tillyard began his observations on the dragonflies of Australia. Previously many interesting spe- cies had been described from that country, but they were all known merely as museum specimens and known only from bare systematic descriptions drawn mainly by writers in other lands. It is fortunate when the fauna of any land is studied on its own soil; but in the case of Australia it is especially for- tunate because of the large number of archaic types there oc- curring, concerning which a more intimate knowledge has long been desirable. Such knowledge has been furnished by Tillyard in a large measure ; knowledge of life-histories and of habits, of ecology and distribution, of structure and development; and it is being published in a series of fruitful papers of so great value that every Odonatologist must wish that the series may long con- tinue. 170 ENTOMOLOGICAL NEWS [Apr.0my Two of these papers! deal with wing tracheation, and, like the others, are based on a large first-hand accumulation of facts. Especially valuable is the contribution to the knowl- edge of the development of the Cordulinae, a subfamily that is represented in Australia by many remarkable forms. But all the groups of the available fauna have been extensively drawn upon. Tillyard’s studies of tracheation extend and entirely cor- roborate my own? in so far as facts are concerned; but he of- fers a different interpretation of two matters: (1) the anal veins of the Anisoptera; (2) the radial sector of the Zygop- tera. I desire to restate my views concerning these in the light of the new evidence and arguments he has produced. Tillyard’s interpretation of the anal region of the Anisop- teran wing differs but little from my own. He found, as I did earlier, that the anal trachea is closely approximated to the cubital for a distance and then descends through an ap- parent cross vein; then bends again sharply outward and fol- lows thereafter the direct course of the anal vein. He pro- poses to call the apparent cross vein the “anal crossing,” and this I consider an excellent descriptive term and better than “basal cubito-anal cross vein,’ whether it were originally a cross vein or not; in one instance at least he has shown it is not the most basal of the series of cubital-anal cross veins. Tillyard would call the vein that forms about the conjoined portion of the cubital and anal tracheae Cut A: and I see no serious objection to this, especially since he then disposes of the vein hitherto known as the anal by a device so little incon- venient as merely labeling it Av* It was not merely the thought *Tillyard, R.

Mus. 26: 703-764, 14 plates, 44 text figures, 1903. *In his studies of tracheation of the Chrysopidae (Proc. Linn. Soc. N. S. Wales 41 : 221-248, 1916), Tillyard also uses this simple device most opportunely to obviate a cumbersome terminology when apparently simple and direct veins are variously compounded. The condition there a out was previously noted by McClendon (Ent. News 17: 120, 1906). Vol. xxviii] ENTOMOLOGICAL NEWS 171 of an encumbered terminology, however, but a doubt as to real homologies of the vein that kept me from doing something like this earlier. I found that the anal trachea originates in the position of the straight adult vein, and only later in de- velopment moves up against the cubital, becoming twice angu- lated. I found the extreme base of the wing saclike and open, its membranes tardily fusing to delimit the vein cavities; and it was easy to conceive that a small marginal trachea, like the anal, occupying a constricted place at the base of the wing might have slipped over where there was obviously more room ; and there was and is much doubt in my mind as to whether the vein ever went along with the trachea. This doubt was not resolved by reading Tillyard’s paper, for he brings in no new evidence whatever, and I have not his confidence in the con- stancy of the tracheae. However, Professor Comstock, on reading his paper, set about it and found some new evidence. He reasoned that if the base of the so-called anal vein be a secondary development, some fossil form, if primitive enough, might show its absence. At once he found a single figure of a fossil Aeschna liassina of Brodie, which shows this condition. At least the drawing as offered by Brodie* and copied by Hand- lirsch® shows it. In other parts of the wing, however, this drawing shows obvious inaccuracies. Wherefore, I desired to have the facts confirmed; so I wrote Mr. Herbert Campion to request a re-examination of the specimen. He wrote at once that he though it was in the Warwick Museum, but on the 13th of May, 1916, he wrote again that it could not be found. Assuming the correctness of this detail of the figure, the best evidence now available seems, therefore, to be in favor of Tillyard’s interpretation. Tillyard’s interpretation of the radial sector of the Zygop- tera differs utterly and irreconcilably from my own. He found, as I did earlier, that the trachea corresponding to the radial sector is not attached to the radial trachea in any of the Zygoptera, but appears as an added branch of the median tra- “Brodie. Fossil Insects of the secondary rocks of England, Pl. 10, Fig. 4. *Handlirsch. Die fossile Insecten, Pl. 42, Fig. 1. 172 ENTOMOLOGICAL NEWS [Apr., ee chea. If this trachea be conceived as a new development from the median stem, I see no particular objection to labeling it Ms; it it be the old original branch from radius that has found a new basal attachment it should still be labeled Rs; but the vein which follows it I cannot believe to be other than Rs of Arisepteran wings. As to the adult vein, I entirely agree with Mr. Campion in the opinion expressed in his letter of March 18th last when he said: “That the Zygoptera do not possess Rs at all is a rather startling proposition and hardly one which can be accepted offhand. In Zygopteran and Anisopteran wings alike we find six longitudinal veins to be all located be- tween R and M. These veins occupy exactly similar positions in the two kinds of wings, and I find it exceedingly difficult to believe that they are to be interpreted in one way in the Zygop- tera and in another way in the Anisoptera.” Tillyard demands ontogenetic evidence; and yet, singularly enough, in support of his “unbranched radius theory” he of- fers just the evidence I lacked to give me the greatest assur- ance in the other interpretation. This evidence is not from tracheae, however, but from cuticularization of the nymphal wing—a sort of evidence which he himself stresses heavily in support of his theory concerning the development of the anal area of the wing. This cuticularization (anticipatory vena- tion) of the nymphal wing he shows in his text Fig. 5 (Proc. Linn. Soc. N. S. Wales, 40; 227). This shows an actual cross- ing, for which Dr. Ris’ statement that it is “preparatory to the development of the imaginal venation” is no explanation what- ever. There is nothing like it in insect wings, except in ob- lique veins where tracheae either are present or have been present in earlier stages of development. This crossing fol- lows exactly the course taken by the trachea Rs in the more generalized Anisoptera and is probably the channel which that trachea once occupied. It is for me a most satisfactory con- firmation of the identity of the vein Rs of the two suborders of Odonata. Such differences of interpretation grow out of different Vol. xxviii] ENTOMOLOGICAL NEWS 173 ideas as to how the tracheation should be used as an aid to determining the homologies of veins. The tracheation of a nymphal insect wing is never identical with the venation of the adult wing. It may correspond closely; it may entirely di- verge. Tracheation affords complete confirmation of vein homologies in some of the lower orders, such as Plecoptera and Corrodentia ; it is worthless for such use in other orders, such as Trichoptera and Diptera. It is an aid in most orders, but needs to be used with discretion and with a regard to its limi1- tations. The interpretation of vein homologies by the study of the antecedent tracheae is a method which, like most other methods that we use in zoology, is of value only for what it shows. It is not all-sufficient. Let any one who is inclined to trust to tracheation too far read Miss Morgan’s study of May- fly tracheation® and learn caution. The Odonata are not alone in furnishing examples of the replacement of one principal tracheal branch by another, in- dependent of adult venation. In explanation of its occurrence in the Zygoptera in my paper of 1903” (p. 713), I cite the par- allel well known case of the attachment of trachea M1 to the radius in Picris, a shift of tracheae which has never led Lepi- dopterists to change the designation of the adult vein. Indeed Tillyard himself is not consistent; for in the second of the two papers here under consideration he labels and discusses as branches of A, certain tracheae that spring from the cubital stem! If branches of the anal trachea may be shifted with- out disturbance of the adult vein, why may not those of the radial ? Fortunately, sufficient comparative study will enable one to learn when such shiftings have occurred, so that even in spe- cialized groups the testimony of the tracheae is not wholly in- validated. But if we proceed to change the designation of adult veins without first learning this we shall create for our- selves intolerable and unnecessary confusion. "Morgan, A. H.

By H. B. Huncerrorp, Cornell University, Ithaca, New York. (Plate XIII) After having read in the text-books on entomology that the eggs of back-swimmers are inserted in the stems of aquatic plants, it was a matter of some surprise to the writer when he was informed that such was not the case with those ob- served in America. In looking up the literature he very short- ly discovered that the basis for the statement found in our texts was the fact that Notonecta glauca, common in France, was said by Regimbart (1874) to place its eggs in the “twigs and petioles of plants.” In a paper entitled “Observations sur la Ponte du Dytiscus marginalis et de Quelques Autres In- sectes Aquatiques,’ among the other aquatic insects he de- scribes briefly the egg-laying habits of N. glauca and presents a figure of a stem containing the egg in situ, the cephalic end protruding from the stem. This article, though not the first to mention the method of oviposition of Notonecta glauca, has been widely quoted. An examination of the earlier literature will disclose the fact that the species N. glauca must also sometimes glue its eggs to the stems of water plants. The diversity of statements regarding the habits in question is best shown by a review of the Bibli- ography at end of this paper, wherein are added quotations from some of the various texts from Roesel (1746) to the present time. In 1896 Kirkaldy exhibited the ova of Notonecta glauca var. urcata before the Entomological Society of London and, after quoting Regimbart, made the following remarks: ‘The speci- mens before you, owing probably to the absence of rushes (Juncus) in the vessel, although Anacharis, which one would have thought suitable, was in abundance, are entirely external, affixed basally to the stalk by a glutinous substance, as in the allied Corixidae. That this basal fixation is not usual is evi- dent from the fact that the ova are but feebly adherent, drop- Vol. xxviii] ENTOMOLOGICAL NEWS 175 ping off upon a slight disturbance, whereas the ova of the Corixidae are attached exceedingly firmly.” In 1902 Mr. J. R. de la Torre Bueno called attention to the fact that N. undulata female does not make a slit in the epi- dermis of the leaf or stem, but merely glues the eggs along the sides in a rather irregular fashion on the surface. In his paper on “The Genus Notonecta in America, North of Mex- ica, 1905,” he states that out of some 1300 or 1400 ova of four or five species observed, in all but one instance* were the eggs attached to submerged plants or twigs. Christine Essenberg (1915), in her studies on the habits and natural history of the back-swimmers, reports that the four species with which she worked at Berkeley, California, namely, Notonecta undulata var. charon, N. insulata, Kirby, N. indica and an undescribed species, all attach their eggs to the stems of plants, as noted by Mr. Torre Bueno, and even to the backs of other insects, such as dragon fly nymphs. It would seem probable then that in the case of all of our Ameri- can species of this genus, the eggs as a rule are attached to the surface of their support. Thus a diversity in habits of oviposition between the com- mon European form, as reported by Regimbart, and our own species has been a matter of some interest, and it may add a trifle to our appreciation of the American hack-swimmers to note that among them in the genus Buenoa is one which, with more parental concern than is evinced by even the European glauca, embeds its ova in the stems of water plants. At this point it may be well to recall that there are three genera of the family Notonectidae in America north of Mex- ico. They are Notonecta, Buenoa and Plea, which are repre- sented by 12, 3 and I species, respectively. These may be sep- arated by the following table, wherein is included a key to the species of the genus Buenoa.t AX. IL@gas. cil Sines Ene Bee Sen ArSGr Geet rceao 4 sour Plea Leach. A.A.

Fieb. Of these three genera it has long been known that the tiny Plea places its eggs out of harm’s way in the stems of the aquatic plants. The observations have been for the European P. minutissima Leach, but the same is doubtless true in the case of our own Plea siriola, for the female possesses the necessary equipment for such a task. All American members of the genus Notonecta, at least those that have been observed, attach their eggs by their long axis to stems of plants, submerged brush wood and the like. The egg of \V. undulata, our commonest species, is shown in Fig. 7, Pl. XIII. It is a pleasure to report some observations on the oviposi- tion of the female of one species of the genus Buenoa, which is endophytic in this habit. After futile attempts to obtain the eggs in the aquarium which, it was supposed, would be deposited on the twigs plac- ed therein for the purpose, an examination of the female’s equipment for oviposition disclosed the device shown in Plate XI, Fig 9. With this clue, the pond was visited at once and quite for- tunately the first object examined was literally full of the same sort of ova which had been noted in the bodies of the bugs. It was an uprooted smartweed (Polygonum) floating in the pool some fifteen feet from shore. Not only were the stems of this green bit of smartweed swollen and distorted* by the many eggs it contained, but the leaves also were em- * Stem of smartweed 23 ova crowded in linear space of one centi- meter, — Vol. xxviii] ENTOMOLOGICAL NEWS W777. ployed as nidi with varying degrees of success. The leaves were punctured and the egg, when present, rested suspended beneath, attached by the collar shown in the drawing Pl. XIII, Fig. 1, to the upper surface margins of the incision. The many perforations or slits through the leaves gave their testi- mony to the many failures in attempting to employ so thin a structure for nidification. Subsequently eggs have been found in floating Typha and Juncus and have been deposited in the aquarium in the tissues of both of these plants. The drawings give perhaps a better idea of the eggs and young larvae than a description, but the following are sub- mitted for the purpose of their precise recognition. THE Ovum. Size: 1.125 mm. long by .406 mm. in its widest diameter. The size increases somewhat with the development of the embryo within, which causes a bulging of the stem in which the egg is inserted. Shape. The egg is an elongate oval when seen in surface view with the cephalic end the more pointed. (Surface view = the side, a por- tion of which is exposed to view as the egg lies imbedded in the stem.) In lateral view it appears nearly straight in the outline of its upper surface while the lower is quite strongly curved. Color. Pearly white when first laid—the surface hexagonally reticu- late as in the eggs of Notonecta. A smooth and shiny elongate oval area occupies the anterior half of the upper surface. This is the por- tion exposed and is margined by a whitish band which marks the union of the egg with the surface of the stem when in situ. As the embryo develops, the entire egg becomes deep greyish yellow and the red eye spots and other red markings show through the chorion. The part ex- posed becomes dark amber in color and very shiny in appearance. The surface appears reticulate under magnification. First INstTaR NyMPpH. Size (in millimeters) : body length 1.85, body width .625, head width .5, distance between eyes .156. Fore limb: femur .25, tibia .35, tarsus 25 mm. Middle limb .387, .333 and .275 and hind limb .625, .630 and .625 for femur, tibia and tarsus respectively. Color. Ventral aspect: White—the abdominal fringe of hairs, the ventral abdominal tuft, the hair tufts before the hind coxae and those of middle coxae—black. The hairs fringing the hind tarsi are smoky black as are the middle and fore tibia. Eyes dark red. No indication ’ 178 ENTOMOLOGICAL’ NEWS (Apr. rag of the red pigment in the abdomen so conspicuous in older nymphs and adults. White with the red eyes—the only conspicuous marking. Structural details: The absence of the median abdominal carina from the venter, as is the case also with N. undulata nymphs, is the first and most striking peculiarity. The interspace between the eyes is large. Beak four-jointed as in adult. Tarsi all one-jointed, terminating in two claws. The spiny armature of fore legs is more generalized than in later forms. The fringe of the hind legs confined to the margins of the tarsi. THE OLDER NYMPHS.

The table of measurements above is based on an average of ten speci- mens of each instar. A larger number would be desirable to obtain figures dealing with ratio of growth. The writer be- lieves that an examination of a sufficiently large amount of material would show for head-widths and limb measurements a ratio of 1:1.25. That is to say, the width of the head of the * Bueno gives length of species 6.7-8.1, lat. 2.23 mm. eee ’ Vol. xxviii] ENTOMOLOGICAL NEWS 179 second instar nymph would be approximately 1.25 times that of the first instar nymph. Upon attaining the adult stage a sexual dimorphism becomes apparent. Besides the structural differences of the genitalia, the anterior legs of the male possess on the inner faces of the femora and tibia peculiar stridular areas. The tibial structure is borne on the inner face of a promi- nence, which is formed by the elevation of the inner angle or margin of the tibia near its base into a thin but elongate spur. This spur is lacking in the female and not discovered in the nymphs. (See pl. XIII, Figs. 5 and 6.) THE DEVELOPMENTAL CHANGES. Head. The notocephalic margins of the eyes which are near together and nearly parallel in the adult are relatively much farther apart in the first instar nymph. In the newly hatched bug, the distance at synthlip- sis is nearly 1-3 (one-third) width of head with the margins of the eyes diverging broadly to the vertex. As the development proceeds from instar to instar the eyes are brought nearer and nearer to their relations in the adult where the synthlipsis is reduced to about 7.14% of the width of the head. The beak is four-segmented and the antennae of the nymphs have much the form of those in the adults. Legs. The general form as in the adult. The tarsi of all the legs one-segmented and terminated by two claws. (The tarsi of the adults are two-segmented and end in two claws.) Wings. The wing-pads are very inconspicuous even in the later nymphal instars. By the third instar the pads appear on the antero- ventral margins of the mesothorax as little flaps, the distal ends of which reach a position on a line with the trochanter of the fore leg when flexed. In the fourth instar they are much larger, the apices at- taining to a position on a line with the distal end of the mesothoracic tibiae when the limb is flexed. In the fifth instar they are still closely applied to the side of the thorax, but the tips of the more opaque pads reach a point on a line with the distal ends of the hind coxae. HABITS OF THE SPECIES. Buenoa margaritacea is the common representative of its genus in the ponds and pools of eastern Kansas. It appears to prefer the open water and is in much better equilibrium in its watery world than the Notonectae. Individuals of this species may be seen in large numbers i8o ENTOMOLOGICAL NEWS [ Apr, mee swimming slowly or even poising in mid-water some distance beneath the surface. They abound in waters teeming with Entomostraca, upon which they largely feed, the crib formed by the closure of the anterior two spiny pairs of legs being nicely adapted to the retention of such prey. Their dexterity in the manipulation of this device and its efficiency in retain- ing small beings may be demonstrated quite readily under the binocular, and affords another of nature’s illustrations of the fitness of form to function. Like others of the predatory class of water bugs they do on occasion fall upon corixids and other forms than the en- tomostraca, but not with the regularity of many of the others. Adults appear from early spring to late fall. The eggs may be found in May, the nymphs begin to emerge by the middle of the month and by the 15th of June form a dominant spe- cies to be noted in all stages of development from egg to adult in waters suitable to their needs. _They are wilder and more difficult creatures to rear than the Notonectae, but no less interesting objects of study. So far as the writer is aware there has been nothing noted hitherto concerning their biology and he is glad to record for them something of the economy of their lives. ANNOTATED BIBLIOGRAPHY.

Acronycta wanda n. sp. Ground color a uniform, very dark smoky grey. Head blackish above. Thorax without markings save the usual black line from the palpi to the base of the wings. Primaries with all the markings fairly well defined. Basal line geminate, extending to basal dash. Transverse anterior line gemi- nate, outwardly oblique, the inner line a little more strongly defined than the outer, especially from costa to basal dash. A very feeble median shade runs obliquely from costa to reniform. The transverse posterior line is geminate, the inner line very faint, the outer line black, lunulate, the intervening space paler than the ground color. A diffusely lunu- late, interrupted whitish subterminal line. A dusky terminal line with larger interspacial dots, beyond which is a dusky interline in the fringes; the latter are whitish and cut with black. In fresh specimens thé dots of the terminal line extend as fine black lines to the subterminal line. The basal streak, which in some specimens is bordered with white above, is heavy and extends to the outer portion of transverse anterior line and sometimes a little beyond. A fine dagger mark oppo- site the cell runs a trifle beyond the t. p. line. A similar mark in the submedian interspace also crosses the t. p. line and is much heavier than the other. All veins are marked blackish on outer half of wing. The orbicular is small, concolorous, black-edged, irregular and usual- ly complete. Reniform kidney-shaped, moderate in size and sometimes darkened inferiorly. The two spots are connected by a black line. Secondaries smoky in both sexes. Beneath whitish, primaries a little darker than secondaries, with the usual outer line and discal spots. Expanse, 1.65-1.90 inches (42-48 mm.)

Osburn, of the Connecticut College, New London, Connecticut, has been elected Head of the Department of Zoology and Entomology of the Ohio State University, his appoint- ment to take effect July Ist. He will assume the duties carried during the last nineteen years by Dr. Herbert Osborn, who was last year elected Research Professor and who will hereafter give his entire time to research work, including a direction of research work by graduate students, and, for the present, the Directorship of the Lake Laboratory and of the Ohio Biological Survey. Dr. R. C. Osburn graduated from the Ohio State University in 1898, received a Master’s degree from the same institution in 1900, and the Ph.D. degree from Columbia in 1906. He has been connected as a teacher with the Starling Medical College, Columbus, Ohio; Fargo College, Fargo, North Dakota; Clinton High School of Com- merce, New York City; Barnard College, Columbia University, and the Connecticut College, in which he is now Professor of Biology. Dr. Osburn is known to entomologists as the author of a number of papers on Syrphidae and Odonata and he was for several years President of the New York Entomological Society. He is much interested in the ecology of aquatic insects, but his main work has been upon aquatic invertebrates and fishes. Adult Chrysopidae Do Eat (Neur.). I was very much interested in the Notes on the Feeding Habits of Adult Chrysopidae, by L. Bradford Ripley, in the January, 1917, num- ber of Entomological News. By actual observation I can indorse Prof. Ripley’s statement that Chrysopidae take food in the adult stage. While my observation was of short duration and of a single specimen, it proved beyond a doubt that these insects are far from being abstinent. On the evening of September roth, 1916, an adult Lace-winged fly was captured and the next morning, having just finished eating a juicy pear, I had occasion to examine this specimen which was in a stupid condition, as I now believe for the want of food. No sooner had I taken it into my hand than it began to gnaw at my fingers, which were yet moist with the juice of the pear. Taking a tip from this, I sprinkled some granulated sugar on my hand which it ravenously ate. Through a hand-glass we saw grain after grain quickly disappear, and this little creature did not content itself to feed among the scatter- ing grains, but waded into the thick of the sugar. This specimen was placed back in the jar with some sugar and water where it remained until the next morning when I took it from the jar to feed it some more pear juice. When placing it on my hand, as I had the day before, I found to my disappointment that I did not have the little pet that I thought I had, for it briskly flew away, showing that the gentleness of the day before was caused by hunger. After finding that these insects feed on sugar and fruit juice I have but little doubt about their feeding on the natural sweets of flowers and plants——Wzutton T. Gor, Portland, Oregon. ae ee ENTOMOLOGICAL NEWS. PHILADELPHIA, PA., APRIL, I9I7. Ants vs. Men. The President’s address before the Geological Society of America at Albany, December 28, 1916, printed in Science for February 9, 1917, contains some remarks interesting to the entomologist which the latter would hardly look for in a dis- course entitled “The Philosophy of Geology and the Order of the State.” The speaker, distinguished and honored for his many contributions to his science, “wish[es] to nail [certain theses] on the doors of our temple” of geology. Among them are Nature makes for the individual . . . In the progressive line of development which in the present terminates in us, the procedure of nature has been one of only limited concern for the family and of tried out and abandoned experiment for social partnerships and the division of labor. A lively account of the “six-legged articulate expression of existence” which “has led. to most extraordinary displays of morphological and psychic differentiation,” culminating in the ants, “nature’s great triumph, her highest performance in com- munistic effort and in co-operative achievement,” is brought to the astonishing conclusion that The six-legged type with all its purposes, in its highest expression lies prostrate on the ground at our feet, it and its achievements have risen to nothing higher than an ant hill, its communistic relations and subservience are entirely apart from the true genius of humanity For the former the student of nature’s history sees no out- come. We say astonishing, for, while we are well aware that the anthropocentric conception of the universe still permeates the 185 bd 186 ENTOMOLOGICAL NEWS [Apr x great mass of humanity, we thought that scientific men at least were able to throw off the egotism of their own species and look at nature from a detached standpoint. We can as little foresee that there will be no outcome for the ants as Cuvier was able to foresee the downfall of his law of correlation of parts. With the human species at the present time engaged in an almost universal attempt to destroy itself, it is farcical to talk of its “active, progressive and fertile individualism,” while the success of Argentine, leaf-cutting and other ants throughout the world, despite human objections, gives one a sufficient basis for expecting as long a continuance of these pertinacious insects on the earth as of the, one would like to say, Satirically named Homo sapiens. The Host of Ablerus clisiocampae Ash. (Hym.).* The following note is in corroboration of the observations made upon the host of Ablerus clisiocampae Ash. by L. T. Williams. (Psyche, October, 1g16.) In the spring of 1915, the writer bred several specimens of Ablerus clisiocampae from the eggs of Malacosoma americana Fab., but at the time was unable to make sure that the parasite had not emerged from a scale insect, although it hardly seemed possible. In the spring of 1916, after a few specimens of Ablerus had appeared, a rumber of egg masses were taken from the twigs, and thoroughly examined for the presence of scale insects, but none were present. With all possible chance of the presence of scale insects thus eliminated, the parasites continued to emerge from the egg masses in fair numbers. A repetition of the experiment gave the same result. These observations corroborate those made by Williams and the original ones made by Ashmead, that this species, contrary to the habits of the family to which it belongs, does at least at times parasi- tize the eggs of a Lepidopterous insect. In addition to Ablerus clisiocampae, three other species of parasites were bred from the egg masses. They were kindly determined for me by Mr. A. A. Girault as Telenomus coloradensis Crawford, Tetrast- chus malacosomae Girault, and Ooencyrtus sp. Of these, Tetrastichus malacosomae was by far the most abundant, the other two species being only occasionally found.—B. A.

Decatur, Illinois, Feb- ruary, 1917. Published under the patronage of Miss Jessie D. Gillett, Elkhart. Indiana. It has been thirteen years since we have had a list of North Ameri- can Lepidoptera and, as the authors say, many new species have been described and revisions made in many groups and also changes in classification. Such a list is always useful, as far as it goes, and the present one has brought the Lepidoptera up to the present state of our knowledge. Six hundred and sixty-one species of Rhopalocera are listed as compared with six hundred and ninety-eight listed by J. B. Smith in 1903. This difference is due to some of them being reduced to the synonymy and others being considered varieties or aberrations. The genera used are more in harmony with common sense than as hitherto used by some persons, but of course there is much to be done to place them on a firm foundation, Eight thousand Vol. xxviii] ENTOMOLOGICAL NEWS IgI four hundred and ninety-five species of moths are listed, whereas Smith’s list went to seven thousand, one hundred and sixty-nine, an increase of one thousand, three hundred and twenty-six. This is a very considerable increase, and while there will be still more species of moths described, there will also be a considerable re- duction by synonymy, varieties and aberrations, as the genera are revised and the relationships of the species better known. It goes without saying that other students will not agree in all cases with the authors in regard to the standing of the species, but that is to be expected, as such a work always shows a certain amount of personal opinion. Taking it as a whole the authors have been conservative. The complete index is valuable. We find nothing to condemn and much to praise, and trust that those persons for whom the work has been prepared will be duly appreciative —H. S. Doings of Societies. Feldman Collecting Social. Meeting of December 20th, 1916, at the home of H. W. Wenzel, 5614 Stewart Street, Philadelphia; twelve members present. President H. A. Wenzel in the chair. Prof. J. G. Sanders, State Zoologist of Pennsylvania, elected an honorary member. Lepidoptera. Mr. Daecke mentioned that a Mr. Anderson had found larvae of Vanessa antiopa Linn. on willow along the Susquehanna River, at Harrisburg, Pennsylvania, from which was reared one, on September 1st, that has a yellow band covering the outer half of wings; this was exhibited and is var. hygiaea Heg.; he stated that the only record he knew of this “freak” is in Holland’s Butterfly Book, p. 169, pl. xx', fig. 4, 1910. Coleoptera. Mr. H. W. Wenzel exhibited his rearranged col- lection of Colydiide and Cucujide. Dr. Castle exhibited two specimens of Pelenomus obscurus LeC. from Detroit, Florida, October 15; a species with very peculiar antenne; he also has it from Savannah, Georgia. Mr. Wenzel said all his specimens are from Texas. Dr. C. also reported breeding Callidium antennatum Newm. from the larvae in logs brought to the meeting of September 20th by Mr. Hoyer. Mr. Laurent, quoting from an article published in Science of November 17th, 1916, entitled “The Synchronal or Simultaneous Flashing of Fireflies,” stated that he did not believe any such occurrence ever took place, that it was nothing but the twitching of the observer’s eyelids. Some years ago he saw what he thought to be a case of simultaneous flashing of fireflies (Lampyride) ; however, he soon discovered it was nothing but the twitching of his eyelids that caused the effect and the insects had nothing whatever to do with it.

Eleven persons present. Director Philip Laurent presiding. Dr. Calvert exhibited specimens of some of the more striking insects which Mrs. Calvert and he had collected in Costa Rica and which they had arranged for reproduction as a colored plate in their book on Costa Rica soon to appear. He also exhibited plates showing the progressive steps necessary to produce the finished four-color plate. He also spoke of some of the peculiarities of these insects and why they chose them for their illustration. A demonstration was made of a new stereopticon purchased by the Section. Orthoptera—Mr. Hebard exhibited a few specimens of earwigs showing extremes in size, the largest being 37 mm. and the smallest being 2.5 mm. in length. He also spoke about some of the interesting species of this family of insects.—E. T. Cresson, Jr., Recorder. Entomological Workers of Ohio.

HOWARD NOTMAN, 136 Joralemon St., Brooklyn, N. Y. ‘hs Celebrated Original Dust and Post-Proof / METAL CABINETS FOR SCHMITT BOXES _ These cabinets have a specially constructed groove or trough around the front ed with a material of our own design, which is adjustable to the pressure of the front cover. The cover, when in place, i is made fast by spring wire locks or clasps, causing a ‘constant pressure on the lining in the groove. The cabinet, in addition to being abso- lutely dust, moth and dermestes proof, is impervious to fire, smoke, water and atmos- “pheric changes. Obviously, these cabinets are far superior to any constructed of non- metallic material. ae The interior is made of metal, with upright partition in center. On the sides _ are metal supports to hold 28 boxes. The regular size is 424 in. high, 13 in. deep, 182 _in. wide, inside dimensions; usually enameled green outside. For details of Dr, Skin- _ner’s construction of this cabinet, see Entomological News, Vol. XV, page 177. METAL INSECT BOX has all the essential merits of the cabinet, having a groove, clasps, ete. Bottom inside lined with cork; the outside enameled any color desired. The regular dimensions, outside, are 9x 13x 24 in. deep, but can be furnished any size. : ‘WOOD INSECT BOX.—We do not assert that this wooden box has all the quali- ties of the metal box, especially in regard to safety from smoke, fire, water and damp- ness, but the chemically prepared materia] fastened to the under edge of the lid makes a box, we think, superior to any other wood insect box.
