1. Chœtopsylla setosus sp. nov.— Nearest to Ch. ursi, Rothsch. (1902), but easily recognized by the shape of the abdominal sclerites and the tarsi.

Head.—The labial palpus consists of about ten segments, reaching beyond the trochanter, while in ursi there are seven or eight segments only. There is one row of four or five bristles before the eye. The occiput bears two or three hairs behind the base of the antenna, a lateral row of four or five bristles in the centre, and a subapical row.

Shortly before the destruction of my laboratory in 1903, I began to study some of the young females of several species of Coccidœ, for the purpose of determining if there were any constant structural characters present that would enable one to identify the adult female scale, and if there were any characters could be used in the classification of the several genera.

Among some mosquitoes lately sent from Alaska is a species which, coming from the far north (65° N.), has the unique position of standing near three mosquitoes found in much warmer climates, i.e., Theobaldia annulata, Sharnk, found in Europe, Mexico and California, an Italian species of which Falbici says, “Fin ora fu trovata solamenta a Macareseed a Pato,” and penetrans, R. Desvoidy, found in France.

Orthezia Californica, sp. n.—Female about 4½ mm. long3½ mm. broad, and 2 mm. high. Body flat, very firm, and covered with thick lamellæ of a light brown colour. Margin beset with broad wax lamellæ, which grow larger caudad, ending in two, which form a shield-like process. There are three shield-like lamellæ on the anteriro part of teh dorsum; candad of these is a deep carina, formed by two rows of lamellæ running parallel and ending at the caudal shield-like process.

In looking over my collection, preparatory to a rearrangement of them forms, I find several new species, that I desscribe below. One of them represents an interesting new genus, allied to Nemoura. I have added illustrations of the gential structures, as these are of considerable value in the determination of the species. I hope soon to be able to prepare a revision of our species of this family, one of teh most primitive of existing winged insects.

Conotrachelus tuberculicollis, new species.— Form and size of juglandis, but thorax distinctly tuberculate, colour more uniform grayish, and the post-median fascia on elytra indistinct. Head densely covered with ochreous and white scale-like hairs; eyes separated by about the width of the beak; the beal slender, separated from the heady by a shglt transverse impression, about as long as head and thorax and slightly curved, distinctly tricarinate to about apical third, where it is closlely punctate; from base to about middle the surface is sparsely clothed with pale scale-like hairs; antennæ insterted about apical third, first joint of funicle slightly stouter than the second, but of nearly equal length.

The long-expected paper by Dr. Wm Dietz entitled: “Revision of the Tineid Subfamilies, Amydriinœ and Tineinœ, inhabiting North America,” appeared during the writer's absence in Europe, and a subsequent summer's expedition to the West Indies make it impossible to give this important contribution to the knowledge of our American Tinediæ the attention it deserved before early this year.

During the past summer the Locust Mite (Trombidum locustarum, Riley) has been very common at Guelph, especially on the Red-legged Locust (Melanoplus femur rubrum), but a few specimens have also been found upon the Two-striped Locust (Melanoplus bivittatus). The mite is most generally found attached to the base of the second pair of wings, although it is alos found on the wing itself, and on any other part of the body where it cannot be readily detached by the locust; a favourite position upon the body is between the segments of the thorax and abdomen, and also behind the upper joints of the legs; in such postion their only means of attachment to their host is apparently by theri mandibles.

Dolerus Cookei, n. sp.—Female.—Length, 4 to 4.5 mm. Expanse of wings from tip to tipm 8 to 9 mm. General colour effect of body dark brown to black. Head back of, about and beneath ocelli, sparsely clothed with whitish hairs. Clyepus sinuate, incurved, yellow, sparsely pilose. Labrum polished yellow. Antennæ dark brown to black, stout, pilose. Joint i annd ii subequal, short; rest subequal, longer. Antennal foveæ circular, deep.
