During the summers of 1901–2, while at the Minnesota Seaside Station of Vancouver Island, Professor Raymond C. Osburn collected a number of Diptera, and during the these same seasons and the past summer Professor R. V. Harvey, of The Queen's School at Vancouver, British Columbia, collected in the same order. Since so little has been published on the Diptera of that province, we have thought that even a short paper on the Dipterological fauna would be of interest and probably of some value.

The first guide to the bees of the “Great Northwest” is presented in the hope that it will encourage the collection and study of these interesting insects in a region which is only now beginning to yiedl its treasures in this department of science.

The species are, in the main, arranged from generalized to specialized types; the groups follow one another, as in the recently proposed scheme of Mr. Charles Robertson, whose papers on the classificatios of bees have appeared, with few exceptions in this journal.

Mr. Jacob Schreiner, of St. Petersbug, Russia, has been sending me for names some of his rearings of parasitic Hymenoptera, among which are many interesting species.

On April 24th two ♀ ♀ of this month were found resting on the ground within a cluster of Sumach-brush, at Wooside, Long Island, N. Y. Their bright yellow colour had faded to pale ochre.

Eggs were deposited from April 24th to 28th, only during the night. According to circumstances they are secreted within the fissures of the leaf-buds and narrow crevices of bark, or into the folds of decaying leaves of the food-plant. In the first case the nearly elliptical eggs are fgastened erect, close together, in a single row; when attached to a broader surface they are arranged in small regular patches or rows, but deposited lengthwide, the next one always overlapping the preceding one with its, blunt, micropylar end.

In the first week of July my attention was drawn by my friend, Mr. Joshua Thomson, of Levis, to a strange sight, The plum trees in his grounds were infested with myriads of a new species of Torymus, as many as thirty of the insects appearing on one plum. I never witnessed anything in my entomological pursuits more remarkable. The brilliant little creatures could be seen in the act of depositing their eggs; their ovipositors thrust deep into the fruit. Some of the plums attacked showed signs of a previous attack of the Curculio, but most of them did not. Whether the larvæ of the species feed on the flesh and juices of the plum or attack the grubs of the Curcuiio, I cannot say, for I was unable to follow the life-history of the species.

Stagmatoptera typhon, n. sp.—Type ♀; Sam Marcos, Nicaragua (Baker). Acad. Nat. Sci., Phila.

Allied to sancta and birivia, Stoll., and insatiabilis, Rehn. From the sancta-insatiabilis type it differs in the shorter and broader tegmina and wings, the wider and more rotundate expansion of the pronotum, the deeper head and slenderer anterior femora. From the birivia type it can easily be distinguished by the extremely short and broad wings and legmina, the more arcuate expansions and more compressed shaft of the pronotum, as well as the absence of distinct maculations on the tegmina.

Through the courtsey of Dr. Harrison G.Dyar I have had the privilege of examining and assisting in the identification of all the specimens of the family Tortricidœ collected and bred by him and his assistants during the past summer at and in the vicinity of Kaslo, B.C. A completed list of all species will be included in Dr. Dyar's comprehensive paper on his summer's work, which is in course of preparation. All of the species that appear to be unknown are described in the following paper. Prof. C.H. Fernald has very kindly read over the MSS and examined the types, and confirmed my generic determiantions, and in the case of one species made a correction, for all of which I am glad to acknowledge my obligation.

Catocala obscura, Strecker. — Larvæ taken under hickory bark. Foodplant hickory. Described June 1st, 1903.

General colour, gray with pale brown and black markings.

No transverse band and no elevation of eighth segment.

Head broad as first segment, flattened, gray, with a black dash on each cheek, extending from mouth two-thirds of the way to top of head, and ending in a point.

Tubercles white, but not prominent; the dorsal tubercles being in a brownish stripe that is fairly distinct the entire length.

Dryinus nigrellus, sp. nov.—Femal. Length 4.25mm. Wholly black, except tarsi, part of antennæ and mandibles. Head black, finely rugulose, faintly silvery pubescent and sub-shining. Vertex impressed; front wiht a short median impressed groove above the antennæ. Cheeks roughened; mandibles pale yellow, with the tip of the teeth black' quadridentate, the outer tooth the larger and the inner one extremely minute; palpi black.

This genus was established by Lord Walsingham in Illustrations of Typical Specimens of Lepidoptera Hetercera in the collection of the British Museum, Part IV., North American Tortricidæ, p. 68 (1879), with emarginana, Wlsm, the only species under it. This variable species was taken in Mendocino and Lake Counties, California, in considerable number (about 40 speciments) in June, 1871, and five varieties were described. His Lordship had the great kindness to give me several examples representing the different varieties.
