During the summer of 1930, I returned to the north shore of the Gulf of the St. Lawrence and spent three months collecting there. Most of the collecting was done at Thunder River, a village on the mainland opposite the western end of Anticosti Island, and at Bradore Bay, situated at the western extremity of the Straits of Belle Isle.

The following species, with one exception. are a part of those loaned me by various institutions during the course of my work on a revision of the North American species of the family.

The location of the type is, in every case, indicated immediately after the description.

Incubation.—Eggs laid in the laboratory January 25 required only 12 days to hatch. This is apparently the length of the normal incubation period. The embryo does not completely fill the egg until shortly before hatching, and its white color forms a contrast against the transparency of the egg shell.

In the “Canadian Entomologist” for March, 1930 (pp. 54-62) I commented on the Ephenteroptera collected in 1929 by W. J. Brown at various points along the north shore of the Gulf of St. Lawrence. Further studies by Mr. Brown in 1930 at Thunder River (June 12-28 and Aug. 15-29) and at Bradore Bay (July 4-16 and July 29-Aug. 12) have resulted in a number of additional records which I present in the following paper.

Male. Very similar in all respects to guttata McD. but noticeably larger in size. Thorax deep blackish, tinged with brown in the pleural sutures. Abdomen with segments 2-6 and anterior portion of 7 whitish, hyaline, with considerable brownish shading on 2. In place of the lateral black dots of guttata there is a short black transverse streak in the postero-lateral corner of segments 2-6 with some slight brown suffusion anterior to it, especially on segment 2. Rear segments deep chocolate-brown.

Antennae blackish brown annulated with white to grayish; markings in some specimens indistinct giving the antennae a light blackish brown appearance. Palpi, second joint blackish brown with the apex, a narrow strip and the base internally, white; terminal joint blackish brown with tip and base white scaled; face and head white with the tips of the scales light blackish brown. Patagia, base blackish brown, posterior part white mottled with blackish brown. Fore wing, ground color white ; many of the scales tipped with blackish to light brown; at base on costa a blackish brown area; just before middle, on costa a large blackish brown triangular patch, the apex of which extends into the center of the wing; a few yellow ochre scales on the margins of the triangular patch.

General ground color semihyaline to white, marked with orange. Vertex with semblance of five white spots more or less surrounded with orange bands. Median white spot usually elongated and with very thin median orange line. Pronotum with median elongated spot often touuching posterior margin, usual angular spot back of each eye.

Orthotype. Chelifer sculpturatus Lewis.

Diagnosis and remarks. Characterized and discriminated from its relatives in the preceding keys. Three species (two South African and one Indian) may be referred to the genus. They may be separated by means of the following keys.

Several interesting records on Canadian Sarcophagidae have come to hand during the past several years. Two of these records, with the description of an undescribed species from Canada, are as follows.

An effort has been made in the preceding pages to present all the species of Erythroneura that have been described in the Maculata Group as well as a large number of new species. The scutelleris Group is included also because it was found they could not easily be separated on the external characters as given by other writers and the genitalia showed close relation to the Maculata Group. No doubt other species will be found as more intensive collecting is done in various parts of the country.

The foliowing is the original description: “Markings of head, thorax and scutellum as usual inthe maculata type, yellow; tegmen with a streak along claval suture auteriorly, an oblique dash at base of corium and another at anterior end of costal plaque, yellow; dot at posterior end of plaque, and in base of fourth apical cell black; and the following markings red, broad vitta based on costal plaque, extending inwardly and crossing clavus as oblique broad band, and a straight narrow stripe, connected narrowly behind to a spot which spreads so as to fill spaces betuween sectors anterior to third and fourth apical cells, also ramose marking on cross veins ; costal plaque dusky bluish hyaline, apical cells fumose. Color below pale yellow. Length: 2.75 mm.

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.

The Canadian bees now described were received from Mr. Albert F. Winn; the types are in my possession.

Andrena lucifera n. sp.

♀. Length about 9 mm., expanse 18; black, including mandibles and legs, the antennae black with the flagellum thickened and faintly brownish beneath beyond the base; pubescence of head and thorai very scanty, dull white, the thorax almost nude above, the sparse hair easily deciduous; head broad, facial quadrangle conspicuously broader than long; mandibles ordinary, malar space linear; process of labrum very large, obtusely triangular, shining; clypeus wholly dull, with a minutely granular surface, and sparse punctures; no smooth line, though the middle is slightly elevated: on each side above the clypeus, from the antennae to the orbits, is a broad highly polished area, but the supraclypeal area and middle of front are dull; facial foveae moderately broad, with shining white tomentum; distance from upper end of fovea to lateral ocellus about or nearly as great as width of fovea; below the foveae extend (with approximately even width) below level of antennae, and are separated from orbits by a shining line; cheeks shining, convex, very broad, the upper part strongly keeled behind; third antennal joint fully as long as 4+5; meso-thorax dullish, more shining posteriorly, without evident punctures under a lens, but the microscope shows a minutely tessellated surface and scattered small punctures; scutellum polished, with a median impressed line; mesopleura glistening, rugulose, the lower part produced into a sort of tubercle, and the shining anterior face of lower part having a triangular outline; metathorax dull and granular, but the large basal area triangular, with numerous conspicuous plicae, radiating at sides and a few stronger ones in middle; tegulae reddish brown, anteriorly blackened; wings conspicuously reddish, stigma dark reddish brown, the middle darker than the margins, veins brown; basal nervure falling well short of nervulus; second cubital cell narrow, much higher than broad, receiving recurrent nervure not far from end; legs with pale brown hair, the hind tibial scopa wholly pale, faintly reddish, the hairs on outer side simple; spurs normal, pale reddish; abdomen broad, highly polished, nude above, without bands, the hind margins of the tergites obscurely brownish; under a lens no distinct punctures are visible, but the microscope shows sparse minute punctures; apical depression of first tergite short, of second less than half distance from base to apex, but rather more than two-fifths; apical fimbria pale brown; venter with dull whitish hair.

On May 29, 1926, the writer found several Gomphus nymphs on the muddy bottom of the Credit river at Erindale, Ont. It was on a quiet pond-like part of the river, where there are patches of cat-tails (Typha latifolia L.) and some other emergent plants, but only a few yards below a considerable stretch of shallow rapids.

The species described below are from sereral lots of beetles submitted to the author during recent months. Several of the species are of unusual interest, especially the Phytobius and the Trichocellus. The latter represents a subgentls new to North America and was included in a fine lot of arctic beetles collected by Mr. A. E. Porsild. The collections made in British Columbia by Mr. G. Stace Smith continue to add materially to our knowledge of the beetles of the province.

This species has apparently been introduced in recent years and become established as a pest of the common native alder (Alnus rubra) on the west coast of Washington and British Columbia, particularly in the lower part of the Fraser River Valley. The earliest specimens I have at hand are a series of 15 females taken at White Rock, B. C., June 28, 1929, collected by Mr. G. Beall.

Characterized by the reduction of white shading on primaries, notably in the basal and median areas; in the latter section the reniform alone shows up prominently as a white half-moon; there are traces of pale filling in the t. a. and t. p. lines; s. t. line scarcely indicated. Expanse 40-45 mm.

The following notes are based on material in the Canadian National Collection at Ottawa. A large proportion of the reared material was obtained by Dr. J. McDunnough at Bobcaygeon, Ont. in the course of his studies on the Lepidoptera of that region. His rearings of several species of Haploptilia yielded a number of parasites the habits of which have heretofore been little known in Canada. Other material mentioned below was reared by the writer and by various economic officers of the Entomological Branch staff. The determinations of the lepidopterous hosts of the Bobcaygeon material are by Dr. McDunnough.

The purpose of this paper is to present what is known at the present time concerning the life histories and habits of the Mesoveliidae, particularly those of three species of the genus Mesovelia Muls. found in North America. Studies on our most common species, Mesovelia mulsanti bisignata Uhler, were carried out in Michigan and Kansas, while biological notes on the other two species were taken in the region of Douglas Lake, Michigan, their only known habitat. Isolated rearings and life history studies of all three species were made at Lawrence, Kansas.

Two of my colleagues, in years long gone by, have brought back to me from their journeyings specimens of interesting undescribed mayflies that I have placed in the Cornell University collection to arvait for study a more convenient season. Three of these I now describe. The first two are rather unique species of two well-known genera.
