Resembling caperatus in size and general appearance but without color markings, apparently more closely related to apicatus and alboneura but with short wings. Length 2-2.5 mm.

Vertex bluntly angled, a little longer on middle than basal width between eyes. Elytra short covering only first four or five basal segments of abdomen, apical cells very small.

Color straw yellow, frequently unmarked. Ocelli black. 111 dark specimens with faint markings on vertex. Four large brown spots on anterior margin of pronotum and veins of elytra heavily infuscated.

Phyciodes tharos var. arctica Dos Passos. This recently described Newfoundland race (1935, Can. Ent. LXVII, 87) was differentiated from the typical form largly on the strength of the more orange coloration of the underside, especially of the hindwings, the author stating it to be “zinc orange” as compared with the “naples yellow” of tharos proper.

In the preparation of the following notes, I have become indebted to Professor E. H. Strickland and Mr. C. A. Frost for the loan of specimens and to Mr. P. J. Darlington Jr., and the Museum of Comparative Zoology for the loan of much material and for permission to study the aedeagus of the type specimen of carbo Lec. Mr. K. G. Blair, by comparisons with types, has nlade it possible for me to identify semimetallicus Walk. and aeripennis Kby.

Within the last few years parasites have become of increasing importance in the control of the oriental fruit moth, Grapholitha molesta Busck. Dr. Van Steenburgh, in a paper to be published in the Report of the Entomological Society of in Ontario for 1934, has reviewed their importance in Ontario and has shown that Glypta rufiscutellaris Cress. is the predominant native species, ranking next to the introduced Macrocentrus ancylivorus Roh. Cremastus minor Cush. is of secondary importance, while the other species occur only in small numbers.

This group includes four black species which have the size moderate or large, the antennae strongly serrate, and the apical antennal segment constricted. All of the species are well characterized and can be recognized without much difficulty. The three western species, cribrosus, maurus, and colossus were confused together by Van Dyke in his recent synopsis (1932, Proc. Cal. Ac. Sci. 4th ser., XX, 408). Dr. Fall (1934, Jour. N. Y. Ent. Soc. XLII, 32) has given reasons for rejecting Van Dylie's arrangement, and I am in full accord with his conclusions.

Under the present listing the genus includes the species anceps Steph. (confragosa Morr.) and contadina Sm.; however, on the strength of the similarity of male genitalia, I believe that loda Stkr. should be transferred here from the genus Eumichtis Hbn. The two last-named species form a group in which the male antennae are serrate and fasciculate in distinction to the pectinate antennae of the genotype, anceps. Contadina was described from a specimen from Victoria, B. C., and is easily separated from loda by the whitish thorax and strong white suffusion in basal and terminal areas of forewing, loda being a rather unicolorous dark blackish, ercept for the whitish crosslines and spots; it also occurs on Vancouver Island and in the interior of British Columbia.

On June 17, 1934, three or four green cones of Pinus ponderosa Dougl. were collected which showed some insect damage.

Upon examination, almost mature larvae of this Dioryctria were observed to have eaten away practically the entire inner portion of the cone, leaving the axis and the outer portion.attached at the top and bottom so as to form a rather large retreat.

Of the two moths obtained, one emerged June 26 and the other June 29, 1934.

In 1894 Horn (Proc. Cal. Acad. Sci. ser. 2, IV) recorded twelve species of Histeridae as occurring in Lower California. One, Carcinops viridicollis Mars., was omitted, but Lewis (1888) and Leng (1920) Both record it from lower California, and one, Iliotona beyeri Schffr. (1907), has since been described from this region. In the present paper, one known and three new Histeridae are added to the list, thus raising the total numher from this region to eighteen.

Aphids of many kinds persist in causing injury to range plants as well as to shade, forest, ornamental and crop plants. The following report deals largely with aphids taken in Utah and nearby states. The writer is indebted to Dr. A.A. Granovsky of the University of Minnesota for identifying a number of the species belonging to the tribe Callipterini.

Proboscis fully developed. First segment of palpus with a fringe of scales; second segment long, upturned and smoothly scaled. Front rough, with a flattened or somewhat truncated prominence. Genae quadrate ventrally. Male antennae ciliated, scaled above. Fore tibiae with or without claws ; mid and hind tibiae with some fringing scales; mid tibiae of male swollen and enclosing a tuft of long sex scales. Metathorax with slight, depressed tuft. Abdomen smoothly scaled. Venation : fore wing with veins 3, 4 and 5 close together at lower angle of cell, 6 from upper angle, 7 connate from end of areole with 8+9 which are long-stalked (three-fifths distance from areole to margin), 10 from areole, 11 from cell; hind wing with veins 3 and 4 usually connate, 5 arising near 4 and rapidly diverging, 6 and 7 connate from upper angle, 8 touching cell at point only.

The following new species of Eleodes have recently, come to hand and are described as follows:

Eleodes indentata n. sp. (Subgenus Blapylis Horn.)

Female—From ovate, about twice as long as wide, widest across middle of the elytra. Color deep black, luster polisheci ancl shining.

Head slightly widest across the eyes, before the post-ocular line a little more than twice as wide as long; sides of the front scarcely as prominent as the eyes, arcuately convergent to the oblique sutures and there broadly sinuate; sides of the epistoma straight and convergent, angles evenly. rounded, apex broadly sinuate : frons feebly convex, s1ight1y and broadly impressed within the moderatc supra-antennal convexities, very densely punctate, punctures coarse and more or less coalescent, smaller on the occiput. Labmrum transverse, densely punctete in apical one-half, thence to base smooth and very sparsel punctate.

The 1933 experiment in hybridizing Tropaea luna with Actias selene closed in the following manner:

Cocoons of Actias selene, formed in August, hatched in September, and the moths mated. A second brood of larvae was reared on rose leaves (purchased wholesale after the winter set in) but, owing to the difficulty of keeping this food supply fresh, the disease called Flatchery claimed all of the brood except one larva. The single cocoon, spun in December, gave us a female the following June, but this moth refused to mate with males of Tropaea luna.

Oval, slightly oblong, moderately robust, rufocastaneous to brown, dull,Clypeus feebly emarginate, the margin narrowly reflexed, coarsely and deeply punctured, frontal suture not deeply impressed. front more coarsely punctured and with short erect setae. Pronotum obtusely angulate, the lateral margins coarsely crenate and with rather long ciliae, punctures moderate in size separated by 2 to 3 times their own diameters slightly denser near margins, each puncture bearing a short semi-erect seta, median smooth line indistinct to absent in some specimens. Scutellum wider than long, punctures fine and shallow each bearing a short seta, evenly distributed. Elytra with punctures finer than on pronotum separated by 2 to 3 times their onn diameters, each puncture with short semierect setae, longer setae arising from punctures on each side of the scutellum and along the sutural costae and lateral margins, sutural costae well defined, others obsolete.

In the Canadian Entomologist (1882 and 1883) Marten describes 7 species of Tabanus from the western United States of which the location of the types is unfortunately unknown. Certain characters now considered essential for comparative analysis were not adequately treated by him and as the descriptions were apparently based on damaged specimens in 2 instances, and on very restricted numbers in others, some confusion has arisen as to the identity of certain of these species.

During the past few years several workers in culicid biology have made studies of the rest period that accompanies the hibernation of certain temperate and subtropical treehole mosquitoes. Incidental to these studies several attempts have been made to bring on prematurely the phase of active development by artificial agents. Roubaud (2, p. 1126) has shown that young, first stage, Aedes geniculatus larvae can be Induced to hatch from the egg and to begin active development by means of certain enzymatic ferments. As far as the writer knows, no one has yet reported any successful attempts to activate resting larvae in the more advanced stages.

Male. Antennae weakly bipectinate. or more properly speaking lamellate and fasciculate, the width of each lamella being noticeably less than in the closely allied pulla Grt. Palpi and head clothed with rough blackish hairs ; tegulae crested,the basal portion deep smoky, the upper half light grayish tipped with darker, a fine blackish transverse line at the point of denemarcation of the two colors; patagia clothed with mixed gray and blackish hairs ; thoracic vestiture deep smoky with a small blackish median tuft on metanotum.

As our knowledge of the western Ephemerid fauna, particularly in its nymphal stages, increases, cur conception of the individual species becomes more accurate, necessitating in some instances corrections of previous statements, and enabling us to differentiate closely allied species in various groups which here-tofore had been lumped under one name. The basis for the following notes has been the rearings carried on by my assistant, Mr. A. N. Gartrell, in the Okanagan region of British Columbia in 1934.

The Island of Newfoundland is divided into tliree faunal zones—Arctic, Hudsonian and Canadian. The latter two are of about equal size but the first is only a narrow strip along the North and North East coasts. TheCollection hereinafter referred to came exclusively from the southwestern part the island in the Canadian zone. The locality is interesting because this part of Newfoundland remained unglaciated during the last continental glaciation. It possesses a large relict flora of species which have persisted since pleistocene times and it is possible that some insects of that period also survie.

Through the courtesy of Dr. McDunnough, I have recently been permitted to study many specimens of mayflies allied to the genus Iron, which were collected in Western Canada. Imagoes of both sexes and correctly associated nymphs of several species were included in the material, which was loaned to me from the Canadian National Collection. A study of these specimens, together with others in the Cornell University Collection, convinces me that two new genera are represented, which I designate respectively as Ironodes and Ironpsis.

In arranging the National Collection material in Xenoschesis, two species were encountered which appear to be undescribed. The following descriptions are therefore presented with a table to the American species, which are all represented by specimens in the National Collection. Colour appears to be most valuable in separating our species and has therefore been used in the following key. The specimens before me exhibit only slight variation.
