THE GENUS JASSUS IN AMERICA NORTH OF MEXICO. (CICADELLIDAE HEMIP.)
Authors: Lawson Paul B.
Published: January 2010

The genus Jassus is a very large genus of leafhoppers known to occur over a very large portion of the earth. Many species have been described from India, Africa, Central and South America, the Phillipines and several other countries. A very few species, however, seem to occur in America north of Mexico. Since only one of these species is well known, two but slightly known, and two apparently new to science, the writer feels that a short paper introducing us to the small part of the genus known to occur in the United States would not be out of place. A paper on the other American species is being prepared and should be ready for publication before long.
NEW NEARCTIC CRANE-FLIES (TIPULIDAE. DIPTERA). PART XII
Authors: Alexander Charles P.
Published: January 2010

The preceding part under this general title was published in 1921 (Can. Ent. 53 : 132-137). The species discussed at this time are all included in the very extensive series of these flies belonging to the Canadian National Collection and kindly sent to me for determination by Mr. Curran. I am greatly indebted to Mr. Curran, and to the various collectors of the material, for the opportunity of studying this important series of specimens.
THE LEPIDOPTERA OF THE SETON LAKE REGION, BRITISH COLUMBIA
Authors: McDunnough J.
Published: January 2010

Nemoria darwiniata Dyar. A single ♀, June 15.

Nemoria hudsonaria Tayl. Quite common during the latter half of June. In a few of the specimens the inner transverse lines are obsolete and these could as well be placed under unilinearia Tayl. as under hudsonaria. I am not sure at the present time whether the differences given by Taylor are of specific value and until I can study the matter further I use the older of the two names.
SOME NEW CANADIAN SCATOPHAGIDAE (DIPTERA)
Authors: Curran C. Howard
Published: January 2010

The family Scatophagidae, which is richly represented in the northern parts of America and the Old World, is particularly well represented in Canada and most of the species described from America occur in this country. At least some of our species referred to genera established for Palaearctic forms belong doubtfully to these genera and the determination of species is rendered very difficult because the majority of our species have been described in the genus Cordilura. An examination of Loew's types has enabled me to place his species and to determine that a great many of those in the Canadian National Collection are undescribed and descriptions of some of these are now given. Others will be described in a complete revision of the family now under preparation.
NOTES ON THE PHLEPSIDS OF THE SUBGENUS PHLEPSIUS (RHYNCHOTA HOMOPTERA)
Authors: Ball E. D.
Published: January 2010

Osborne and Lathrop have recently given us a very valuable revision of the North American forms of the genus Phlepsius. Their keys and illustrations should make it possible for those interested to make accurate determinations in what has been a very difficult group. The writer in working his material over with the help of this revision found few cases where changes appear to be necessary and most of these were apparently due to the limitations of the material at that time available.
THE LEPIDOPTERA OF THE SETON LAKE REGION, BRITISH COLUMBIA
Authors: McDunnough J.
Published: January 2010

Sericosema wilsonensis C. 8; S. Two males which seem to belong to this species according to genitalia were taken on July 8; the species differs from juturnaria in its sinaller size, lack of the strong ruddy tinges on the underside and in the position of the dark line on underside of secondaries which in wilsonensis is nearer the middle of the wing and more evenly rounded. There is a further specimen in the Canadian National Collection from Salmon Arm, B. C., July 18 (A. A. Dennys). The species does not appear to have been previously recorded from British Columbia.
NOTES ON THE DISTRIBUTION AND HOST PLANTS OF SOME NORTH AMERICAN MIRIDAE (HEMIPTERA)
Authors: Knight Harry H.
Published: January 2010

The following notes have accumulated while collecting and naming species of Miridae during the past ten years. The records are chiefly of species where the distribution is new or of special interest, or to give data on host relationships. I wish to take this occasion to acknowledge the assistance I have received from several botanists who have from time to time determined plants for me.
APHILANTHOPS QUADRINOTATUS ASHMEAD, A WASP WHICH CARRIES HER PREY ON HER STING
Authors: Hicks Charles H.
Published: January 2010

The Peckhams in “Wasps Social anl Solitary” state that (p. 76) “Ashmead quotes from Fabre the remarkable statement that Oxybelus carries her flies home impaled on her sting, an idea that probably arose from the fact that nearly the whole of the fly is visible.” The species they studied, O. quadrinotatus, carried its flies one at a time, upside down head tightly clasped with its third pair of legs, and all of the abdomen projecting beyond the abdomen of the wasp.
PSEUDOMASARIS VESPOIDES (CRESSON), A POLLEN PROVISIONING WASP
Authors: Hicks Charles H.
Published: January 2010

A first account of the habits of Pseudomasaris vespoides has been given by Dr. A. Davidson ('13). He found their nests, usually attached to a twig of a low bush, and built after the manner of the mud dauber wasp but of stony hardness. The completed cell was closed by a stopper of clay which was depressed in the center so that the top of the nest presented a series of small cups. The cup was believed to conserve the rain, soften the stopper and enable the insect to more easily emerge. The cells were thought to have been stored with small larvae. According to Bradley ('22), P. vespoides is found in South Dakota, Idaho, Colorado, New Mexico, Utah, Nevada and California.
TWO NEW SPECIES OF EMPIDIDAE FROM ONTARIO (EMPIDIDAE. DIPT.)
Authors: Walley G. Stuart
Published: January 2010

While collecting in the vicinity of Niagara Falls, Ont., last summer, a new species of Empis was secured and a description is offered below. The species was quite common there during the latter part of June and specimens were found frequenting shady nooks in the rich moist woods of Niagara Glen.
REVISION OF THE GENUS ODONTAEUS, DEJ. (SCARABAEIDAE, COLEOPTERA)
Authors: Wallis J. B.
Published: January 2010

This study of the taxonomic units comprising the genus Odontaeus Dej. has occupied, for the past three years, by far the greater part of such time as I can devote to entomology, and yet it is with a feeling of dissatisfaction that the following conclusions are offered to coleopterists.
THE EVOLUTION OF INSECTS, CHILOPODS, DIPLOPODS, CRUSTACEA AND OTHER ARTHROPODS INDICATED BY A STUDY OF THE HEAD CAPSULE.
Authors: Crampton G. C.
Published: January 2010

The stucly of the arthropod head offers some of the most interesting and important evidence indicating the paths of development followed in the evolution of the various types of arthropods, but the evidence from this source has not been brought together, and nrost of the important types of head capsule have not been figured. The present paper, and the one following it, are offered with a view to supplying this needed information; and in these papers especial attention has been paid to the Crustacea, since these furnish the proto-types of many of the modifications met with in the Insecta, Chilopoda, Diplopoda, etc., and the carcinologists have neglected to furnish us with figures of these important forms.

REVISION OF THE AMERICAN SPECIES OF ARCHYTAS (TACHINIDAE, DIPTERA)
Authors: Curran C. Howard
Published: January 2010

B1ack, antennae partly ancl the palpi apically, reddish; face and cheeks yellow.

EPHEMERID NOTES WITH DESCRIPTION OF A NEW SPECIES
Authors: McDunnough J.
Published: January 2010

In my paper on the Ephemeroptera of Covel Hill, Que., I recorded the spccies E. dorothea Needham as extremely common. In the summer of 1927 my assistant, Mr. G. S. walley, took numerous full-grown nymphs in the Covey Hill brook at a time when the so-called dorothea were emerging, so that the association of nymph and adult is fairly safe. These nymphs, however, proved to agree excellently with the description of cornuta Morg. except for the somewhat smaller size, and a careful reading of Dr. Morgan's description of the male subimago (the only other stage known to her) made it evident that the Covey Hill species should be known as cornuta Morg. and not dorothea Needh.
NOTES ON THE COLLECTION OF MALLOPHAGA
Authors: Wilson Francis H.
Published: January 2010

Probably no groups of living things offer greater difficulties to the student of science than do the parasitic insects. The Mallophaga, or bird and mammal biting lice, stand as an example of this. At the present time there is no species of this order or suborder for which we have the complete life history. There is also a paucity of species descriptions, and host records. Much of the lack of knowledge concerning this group of insects is due, no doubt, to the difficulty of obtaining specimens and the greater difficulty of knowing exactly the host from which a given specimen is taken.
REVISION OF THE AMERICAN SPECIES OF ARCHYTAS (TACHINIDAE, DIPTERA)

THE EVOLUTION OF THE HEAD REGION IN LOWER ARTHROPODS AND ITS BEARING UPON THE ORIGIN AND RELATIONSHIPS OF THE ARTHROPODAN GROUPS
Authors: Crampton G. C.
Published: January 2010

As is indicated by the numbering of the figures in the accompanying plates, the following discussion of the head capsule of lower Arthropods is a continuation of the discussion of the head capsule of higher Arthropods given in a previous paper (Canadian Entomologist, LX. 1928, p. 129). The figures were numbered consecutively throughout all of the plates which were originally intended for inclusion in a single paper, and the original numbering has been retained in the accompanying plates (despite the fact that limitation of space necessitated dividing the original discussion into two parts) because reference was made to certain of the accompanying figures in the previous paper, and it would create confusion to later change the numbers which had been referred to in a previous paper. On this account, the accompanying plates begin with “Fig. 55.” instead of “Fig. I.”

NEW OR LITTLE-KNOWN SPECIES OF THE GENUS TIPULA FROM LABRADOR. (TIPULIDAE, DIPT.)
Authors: Alexander Charles P.
Published: January 2010

Our knowledge of the crane-flies of Labrador is still very insufficient. The most extensive collections that have yet been made are those of Mr. W. W. Perrett, taken in the years 1922 to 1925, inclusive, at and near Hopedale. This important series is the property of the Canadian National Collection and was kindly loaned to me for examination by Mr. Curran, to whom I would express my sincere gratitude.

PSEUDOMASARIS EDWARDSII CRESSON, ANOTHER POLLEN-PROVISIONING WASP, WITH FURTHER NOTES ON P. VESPOIDES (CRESSON)
Authors: Hicks Charles H.
Published: January 2010

Last year I reported P. vespoides (Cr.) a pollen- provisioning wasp and gave some additional facts in regard to its nesting habits and biology. Since that time I have further verified these facts, both in California and in Colorado, and have in addition taken many nests of a smaller species, P. edwardsii Cr.*, at and near Pasadena and Sierra Madre, California. This species according to Bradley ('22) is found in Utah, Nevada, California and Washington.
THE BIONOMICS OF TETRASTICHUS VERRUCARII (CHALCIDO-IDEA) WITH NOTES ON ITS HOSTS (NEUROTERUS SPP., CYNIPIDAE) ON BUR OAK
Authors: Balduf W. V.
Published: January 2010

In an earlier volume (I) the writer presented observations on the bionomics of the parasites and inquilines from the galls of Disholcaspis mamma (Walsh) on a bur oak (Quercus macrocarpa) near Urbana, Illinois. Not less than fifteen species of Hymenoptera were then associated with that gall. In the last two years this gall and its several inhabitants were rare or lacking there, but the leaf galls of Neuroterus verrucarum O.S. and N. niger Gillette were abundant on the same tree. The larvae of the latter cynipids are heavily parasitized by a chalcid, Tetrastichus verrucarii Balduf of the family Tetrastichidae. Observations on the habits and stages of the parasite and its hosts are given below. These records incidentally extend the known hymenopterous fauna of the above tree by four or more species.

PHYSIOLOGICAL DIFFERENTIATION IN OVERWINTERING INDIVIDUAL OF CERTAIN MUSICAL ORTHOPTERA
Authors: Allard H. A.
Published: January 2010

It is well known that many of the crickets and katydids are not as uniform in their mass population as external morphological characters such as the systematist deals with would make them appear. The sequences of the seasons have made possible certain physiological segregations and expressions both in plants and animals. The winter annual among plants is well known, for it is the survival of a plant over the winter in the vegetative condition, usually in the immature rosette stage. As soon as the spring opens these chilled and sluggish plants start into growth and mature their seed in advance of seed sown in the springtime. The Annual Larkspur is a notable example of one of these. Not all plants normally produce winter annuals, for it is evident a plant must possess a high degree of cold resistance.
STUDIES IN THE SCARABAEIDAE (III.)

Published: January 2010

Length 4.5-7 mm.: width 28-4 mm. Broadly oval; moderately convex; feebly shining; blackish, the dorsum with a bluish or greenish tint; body with erect brownish hairs. Head about one-half as wide as prothorax; genae moderately arcuate.
THE SILK SPUN BY THE LARVAE OF CERTAIN SOCIAL WASPS
Authors: Rau Phil
Published: January 2010

The larva of Vespa maculata spins for itself an entire cocoon, a cell lining, plus a lid to its cell. The number of these linings, placed one atop another, shows how often the cell has been occupied by these young wasps. The masses of hard, chalky, red material found in each cell also show by their number how many times the compartment has been used. Each silken lining can be peeled off ; each bag is complete, and at its bottom is this hardened mass of excrement. When one makes a cross-section of the nest, one finds mass upon mass at the bottom of the cells, but each mass is distinct, separated from the others by this tissue.
NOTE ON THE OCCURRENCE OF THE MITE, DERMANYSSUS GALLINAE L. IN THE NEST OF A HOUSE WREN
Authors: Ainslie C. N.
Published: January 2010

Having read of mites swarming in the nests of various birds and being desirous of acquiring information on the subject, I examined the nest of a house wren, Troglodytes aedon aedon, Vieillot, at Sioux City, Iowa, during the summer of 1927. The young birds had the day before left the nest which was built in a small box located on a pillar of my front porch. When the box was opened and the twigs removed, there was a residue of gray powder in the box, amounting to six or seven drams. The microscope showed this powder to be composed of a seething mass of small mites in all stages of development, in countless numbers. Dr. H. E. Ewing, of the Bureau of Entomology, later pronounced them to be the common chicken mite. Dermanyssus gallinae L.
NEW COLEOPTERA XIII

Elongate, entire body and antennae ferruginous, legs a little paler; pubescence very short, yellowish gray, lustre dull from the density of the punctuation.

Head nearly as wide as the prothorax, densely punctate, feebly broadly impressed. Antennae slender, passing by one or two joints the hind angles of the thorax, 3rd joint slightly longer than the 2nd, these together subequal to the 4th.
A SWARM OF MALES OF THE RARE AND PRIMITIVE CRANEFLY PROTOPLASA FITCHII OBSERVED NEAR CHANDLER IN THE GASPE PENINSULA (DIPTERA)
Authors: Crampton G. C.
Published: January 2010

While making an “auto” trip around the Gaspé Peninsula (Province of Quebec) in the summer of 1928. I encountered a swarm of dark-winged insects which I at first took to be may flies “dancing” over a bridge across a river to the west of Chandler—a town on the south shore, well out toward the eastern end of the Gaspé Peninsula. Stopping the car, I descended to inalte a few “investigational” sweepings with my net, and to my utter amazement discovered that I had captured a net full of males of the rare and much-sought (because of its primitiveness) “cranefly” Pratoplasa fitchii, O.S., a member of the superfamily Psychodoidea.
THE LEPIDOPTERA OF THE NORTH SHORE OF THE GULF OF ST. LAWRENCE
Authors: McDunnough J.
Published: January 2010

The following list is compiled from specimens collected by Mr. W. J. Brown in 1929; it should prove of interest to students of geographical distribution, containing, as it does, large elements of the Labrador fauna on the one hand and typical members of the Canadian and Hudsonian zones on the other. As far as I know Wm. Couper has been the only one who has published on the Lepidoptera of this region (Can. Ent., I, 67; IV, 201; VI, 33 et seq.) and his work has been confined largely to diurnals.
CONCERNING SCOLOPS COCKERELLI, (HOMOPTERA. FULGORIDAE)
Authors: Lawson Paul B.
Published: January 2010

In his paper on the genus Scolops (Kansas University Science Bulletin, Volume XVIII, page 417, 1928), Breakey comes to the conclusion that Scolops cockerelli Fowler is a synonym of Ball's Scolops robustus. On pages 427-428 he records the comparison of specimens of a number of closely related species with the type specimen of Fowler's species by Mr. W. E. China of the British Museum.

There is a lower general row of three stout bristles and an upper genal row of six bristles. There is no genal ctenidium. The occipital bristles are arranged in three rows. The bristles of the second antennal segment are short and fine. The club of the antenna is distinctly segmented all of the way around.
NOTES ON SCOTOGRAMMA OREGONICA AND ITS ALLIES (LEPIDOPTERA)
Authors: McDunnough J.
Published: January 2010

The identity of Scotogramma oregonica Grote has always been a matter of some doubt to taxonomists. Smith gave his idea of the species in a paper entitled “Notes on Mamestra trifolii Rott. and Its Allies” (1910, Ent. News, XXI, 357); Wolley-Dod (1913, Can. Ent., XLV, 31) surmises a mixture of species in Grote's type lot of material and states that the male type in the Neumoegen Collection at Brooklyn (now incorporated in the U. S. Natioonal Museum) is the same as Smith's morana (op. cit., p. 361) ; following Dod morana was made a variety of oregonica in the 1917 Barnes and McDunnough Check List.
A COLEOPTEROUS FISH
Authors: Richmond Hector A.
Published: January 2010

While endeavouring to secure my supper from the North Fork of the Ghost River, in the foot-hills of Alberta last summer, it was my good fotune to land an eighteen-inch trout. I immediately set to work dissecting his stomach to determine upon what he was feeding, and the contents surprised me in no small way.
THE GENERA SELANDRIA AND CORYNA IN AMERICA NORTH OF MEXICO (TENTHREDINIDAE, HYMENOPTERA)
Authors: Ross Herbert H.
Published: January 2010

Selandria Leach and Coryna Lep. include the nearctic sawflies of the subfamily Selandriinae in which the costal vein is strongly swollen at its apex. They are of a short and robust form. Enslin (1913) considers Coryna as a subgenus of Selandria, whereas Rohwer (1928) considers the two as distinct. The characters given in the table for the separation of the two genera seem to be sufficient for considering Coryna a good genus.
THE TYPE LOCALITY OF TWO SPECIES OF STAPHYLINIDAE

THE STATUS OF THE BARN SWALLOW BUG. OECIACUS VICARIUS HORVATH
Authors: Spencer G. J.
Published: January 2010

In 1909 I was interested to hear from a farmer in Ontario, that barn swallows are undesirable because they harbour bedbugs which spread from their nests to human habitations. Several times since I have heard the same complaint from various sources. In 1926 an instance cropped up in Vancouver where cliff swallows nests were systematically knocked down from some public buildings, for the same alleged reason.
COLEOPTERA OF THE NORTH SHORE OF THE GULF OF THE ST. LAWRENCE

Piceous with distinct aeneous lustre; each elytron with two yellow spots; the one as long as wide, including hunerus and basal margin and extending inwardly to the third interval; the other elongate oval and slightly oblique, extending from apical third to a point near apex.
NEW COLEOPTERA XIV, WITH NOTES ON KNOWN SPECIES
Authors: Fall H. C.
Published: January 2010

If the species bearing this name in the LeConte ccllection is correctly determined, which I see little reason to doubt, its placement as synonymous with nigrinus Dej. by Horn is surely an error. There are in my collection six examples of this species from Massachusetts and Eastern Canada, and I have seen numerous other examples in the Blanchard and Frost collections, all of which differ very definitely from nigrinus in several particulars.

Mr. C. A. Frost, the coleopterist, to whom of recent years I have been indebted for many interesting and, indeed, rare Heteroptera, has again favored me with some unusual species taken by him this summer (1929), in Nova Scotia. Portaupique, so I learn from Mr. Frost, is on the North shore of Minas Basin, 30 miles west of Truro; Westchester is up in the hills at a lake in the spruce woods.

HETEROPTERA FROM THE NORTH SHORE OF THE GULF OF ST. LAWRENCE
Authors: Walley G. Stuart
Published: January 2010

During the summer of 1929, Mr. W. J. Brown collected numerous specimens of Hemiptera at various stations on the north shore of the Gulf of St. Lawrence from Trinity Bay, Que. eastward to the Labrador boundary. Though the number of species obtained is not large, the distributional records are of considerable interest in that they extend the recorded distribution and add further data on the boreal and holarctic tendencies of certain groups.

NOTES ON CERTAIN BEES, WITH A CONSIDERATION OF THE USE OF THE ABDOMEN IN NEST CONSTRUCTION
Authors: Hicks Charles H.
Published: January 2010

Some wasps make important and prolonged use of the abdomen in the final closure of the tunnel in nesting. This is well illustrated by several species of the spider wasps belonging to the Pompilidae. The use consists of forceful blows or a rapid tapping of the soil with the end or body of the abdomen, resulting in a packing of the nesting material and subsequent greater safety and security to the young. Less well-known and conspicuous examples may sometimes be met with in other wasps.
NOTE ON THE BITING MIDGE, CULICOIDES OBSOLETUS MGN., IN EASTERN CANADA
Authors: Twinn C. R.
Published: January 2010

Little appears to have been written about the tiny biting midges known popularly as “punkies”, “no-see-ums” or “sand-flies” which are prevalent in June and July and persist into August, in many wooded sections of Eastern Canada.
NEW NORTH AMERICAN CAENINAE WITH NOTES (EPHEMEROPTERA)
Authors: McDunnough J.
Published: January 2010

Apart froni the small size of the insects the main obstacle in determining material in this genus has been the difficulty in identifying the species described by older authors. For some time been have been amassing material in the group and I believe that, with more or less topotypical specimens of every described species before me, I have tied down these names with a reasonable amount of surety.

General ground color yellowish white to semihyaline marked with orange. Vertex with three white spots surrounded by thin orange bands. Pronotum with median U-shaped orange mark of varying thickness usually not touching either margin. Usual triangular spots back of each eye. Scutellum with tip orange, basal angles yellow more or less surrounded by orange. Clavi with well defined anchor-shaped spot in basal half and another spat just before tip.
PAUROPODA FROM ALASKA AND THE YUKON
Authors: Hilton William A.
Published: January 2010

I have not found any records of this group of animals from Alaska or indeed from so far north. In the summer of 1930 I searched many localities throughout this region for these and similar animals of similar habitat. I did not find a single specimen of the insect genus Campodea or Japyx. I did not find the larger Symphyla at any time but a number of these small Pauropoda were found in five widely separated places. Two genera of the group were collected with three species in one and one in the other. Although there were some similarities between these four species and others collected to the southward, all were distinct.
SOME ERYTHRONEURA (GRAPE LEAF HOPPERS) OF THE MACULATA GROUP. (HOMOPTERA CICADELLIDAE)
Authors: Beamer R. H.
Published: January 2010

General ground color yellowish white to semihyaline. Color markings red or orange. Veitex with semblance of white spots surrounded with red, heavier red spot on tip. Pronotum with median, rather small, triangular spot with U-shaped anterior margin and usual angular spots back of each eye. Scutellum with spot on tip, basal angles yellow with red dash on exterior margin of each anterior corner. Clavi with usual red basal anchor-shaped mark, often broken in middle, and quite long dash near tip.
NOTE ON THE LARVAE OF METREA OSTREONALIS (PYRAUSTINAE, LEPID.)
Authors: McDunnough J.
Published: January 2010

In the latter part of July 1929 I found several unknown Pyralid larvae tying up the leaves of a shrub of Rhamnus frangula Linn. (indentification by Dr. M. O. Malte, Botanist in the Victoria Museum, Ottawa) in the vicinity of Fulford, Que. The web formed was an untidy sort of affair mixed with dead leaves and excrement, and each web contained only a single larva.
THE BICOLOR GROUP OF THE GENUS EPHEMERELLA WITH PARTICULAR REFERENCE TO THE NYMPHAL STAGES (EPHEMER OPTERA)
Authors: McDunnough J.
Published: January 2010

The following four species are very closely allied and in the adults possess no very definite characters for specific distinction, even the male genitalia failing in this respect. This leads me to believe that we are dealing with a group the individuals of which have split away either from each other or from a parent form at a comparatively recent date and that even now fresh species may be in the act of formation. The nymphs offer much better specific characters and, once recognized, are not readily confused; long series of bred material may result in the discovery of good adult characters but for the present I am basing my conception of the different species largely on nymphal distinctions.
THE NEARCTIC SPECIES OF THE NEMESTRINID GENUS RHYNCHOCEPHALUS FISCHER, (DIPTERA)
Authors: Curran C. H.
Published: January 2010

In 1908 Professor T. D. A. Cockterell, (Trans. Am. Ent. Soc., xxxiv, 247-254) reviewed the American species of the Family Nemestrinidae occurring North of Mexico, including the fossil forms, and in that paper three species of the genus Rhynchocephalus were considered. During the summer of 1922 the author captured a number of specimens of a species of Nemestrinidae while on a collecting trip at Baldwin Hill, about 12 miles from Lawrence, Kansas.
REVISION OF THE NORTH AMERICAN AEGIALIINAE (COLEOPTERA)
Authors: Brown W. J.
Published: January 2010

The following study is based on the types of LeConte and Horn and material from the American Museum, Museum of Comparative Zooslogy, Canadian National Collectioas and from the collections of Messrs. Owen Bryant, C. A. Frost, Ralph Hopping, W. Knaus, and J. B. Wallis. Dr. W. Horn supplied specimens of two European species, of Aegialia rufa Fab. and sabuleti Panz.; these were of much aid in the study of the subgenera, the descriptions of which were made as detailed as possible so that descriptions of the species could be shorter.
THE PRESENT STATUS OF THE LARCH SAWFEY, (LYGAEONEMATUS ERICHSONII HARTIG), IN CANADA, WITH SPECIAL REFERENCE TO ITS SPECIFIC PARASITE, MESOLEIUS TENTHREDINIS MORLEY
Authors: Graham A. R.
Published: January 2010

One of the most outstanding instances of the benefits to be derived from the importation of parasites of our injurious insects, be they of foreign or domestic origin, is to be found in a study of the Larch Sawfly situation in Canada, especially in Manitoba, during the past twenty years.
NOTES ON AGROTID GENERA WITH DESCRIPTIONS OF NEW SPECIES (LEPID.)
Authors: McDunnough J.
Published: January 2010

Genus Prochloridea B. & McD. This genus has been placed in the Heliothiinae but after a study of the genitalia of a male of madonna B. & L., which is probably only a form of the genotype, modesta B. & McD., I believe it should be either placed next or sunk to Rhizagrotis as the genitalia show an extraordinary similarity to those of cloanthoides Grt., the genotype. I have already commented on the position of Rhizagrotis in the “Canadian Entomologist”, 1927, page 64, and restricted it to the species cloanthoides Grt. and albalis Grt.; the structural details of these two species fit in very well with the characterization of Prochloridea.
THE OCCURRENCE OF ATLIDES HALESUS (LEPID: LYCAENIDAE) IN NORTHWESTERN OREGON
Authors: Macy Ralph W.
Published: January 2010

To my knowledge Atlides halesus has not been reported previously as occuring farther north than about thirty-eight degrees N. latitude (southern Illinois), so I believe its presence in north-western Oregon is worth recurding. McMinnville, the location at which I took the examples, is more than seven degrees farther north than points of previous capture. Comstock (Butterflies of Cal., 1927) mentions that this insect is not common in California but that it is recorded from many parts of that state.
NEW ARCTIC COLEOPTERA

Oblong, elongate for the group, and parallel, with rounded humeri ; much depressed; the surface of the elytra are regular, showing but little evidence of impressions except for the quadrate foveae; in color, cupreus above, black beneath. The antennae are black, with the first joint and the under surface of joints three, four and five, almost white. The palpi are black with the first joint pale.
NOTES ON THE SYNONYMY OF CERTAIN EUXOA SPECIES WITH DESCRIPTIONS OF NEW SPECIES
Authors: McDunnough J.

In working over our material in this group I have come to the conclusion that olivalis Grt. was incorrectly listed as a synonym of plagigera in the Barnes and McDunnough 1917 Check List.
OBSERVATIONS ON A UNIDIRECTIONAL FLIGHT OF ARMY CUTWORM MOTHS AND THEIR POSSIBLE BEARING ON AESTIVATION
Authors: Pepper J. H.
Published: January 2010

The life history of the army cutworm moth (Chorizagrotis auxiliaris Grote), the larvae of which over-winter in the soil and mature early in the spring, is characterized by a spring flight in June, their almost complete disappearance during the early part of July and re-appearance during the latter part of August. The period during which they disappear is termed by other workers as an aestivation.
OUR IGNORANCE CONCERNING INSECTS
Authors: Lutz Frank E.
Published: January 2010

Choosing the title of a talk is often a difficult task.

Being naturally optimistic, I wanted to speak concerning some recent advances in our knowledge of insects. But coming to Canada with a talk bearing such a title would seem like carrying coals to Newcastle, since many of the recent American advances in entomological knowledge have been made on this side of the line, and, in the English-speaking world as a whole, most of the advances have been made under the British flag. Furthermore, being naturally a timid soul, I feared discrimination in the selection of examples.

NOTES ON THE EARLY STAGES OF CERTAIN NOCTUID AND GEOMETRID
SPECIES
Authors: McDunnough J.
Published: January 2010

Oncocnemis saundersiana Grt. The young larvae
of this species were first found at Bobcaygeon, Ont., in June, 1931, feeding
within the blossoms of a Pentstemon sp. but died
before reaching maturity. At the same time and place in 1932 a number of
more fully grown larvae were secured, either feeding on the blossoms or
resting flat against the main stem of the plant; the larvae are smooth,
slender and of a pale green color, variably suffused with a pinkish shade,
exactly matching the Pentstemon blossoms, and at
times they may be entirely pink, especially in those instances where the
caterpillar is resting on the flowerheads. Pupation takes place in the earth
and the moth emerges in late August.
THE LARVAL DEVELOPMENT OF THREE BARKBEETLES
Authors: Prebble M. L.
Published: January 2010

The application of Dyar's Law to lepidopterous larvae has been discussed by numerous investigators, who have shown that in many species the head-widths follow a regular geometrical progression in successive instars. Taylor reviews Dyar's Law thoroughly and tests it out on the sawfly, Phyllotoma nemorata (Fallen). The same author examines Dyar's measurements on 46 species of sawfly larvae and concludes that Dyar's Law holds as well for the sawfly larvae as for the 28 species of lepidopterous larvae on which the rule was originally based.

In typical Florida and southern United States examples of cresphontes, the ground color is pale yellow. In this tr. f. the ground color is a deep canary yellow, practically an orange or burnt umber, similar to Papilio rutulus ammoni Behrens which is well illustrated on pl. I of Comstock's “Butterflies of California.”

BOMBARDING BEETLES OF THE GENUS DICAELUS AND HARPALUS
Authors: Fattig P. W.
Published: January 2010

On November 3rd, 1928, I collected at Stone Mountain, Georgia, a Carabid beetle—Dicaelus elongatus (Bon.)—which gave off a very strong discharge of gas which turned to a dense smoke. This appeared to come from the sides of the thorax, instead of from the posterior end of the abdomen as in the genus Brachynus.

Published: January 2010

Traces to section 27 (females) in Cushman's revision of the genus (Proc. U. S. N. M. Vol. 53, p. 513, 1917). Differs from mordellistenae Cush. in having the wings brownish and the face sub-equal in width to the eye length. Differs from incompletus (Prov.) in the brownish wings, the absence of pale orbital lines, broader stigma, broader radial cell and shorter metacarpus. Resembles fuscipennis Cress., but smaller with narrower face, eyes parallel within and abdomen wholly blackish. The male traces to section 13 (males) differing from the male of mordellistenae in the brownish wings, the absence of orbital rings and uniformly dark abdomen. From incompletus it differs in the brownish wings, broader ocellocular space which is slightly greater than the diameter of the lateral ocellus, and the lack of the orbital rings.
