After the removal of the Strongylogasterinœ, which, to a certain extent, from a connecting link between this family and the Tenthredinidæ, but which, on account of their elongate shape and their cephalic and abdominal characteristics, I have placed with the latter family rather than retain here, there need be no difficulty in separating the Selandriidœ from all the other families by the characters made use of in my table.

This genus will have to be transferred to the Noctuidæ.

Larva cylindrical feet normal on joints 7–10, 13, about equally developed. Tubercles minute, setæ long, fine, iv. opposite the lower edge of the spiracle, a little nearer to v. than to iii., and rather far behind the spiracle; setæ single, several on the smooth leg plates. Segments obscurely 5-annulate. All green; spiracles small, brown; no marks; cervical shield and anal plate uncornified, invisible. (Head broken off.) Feeds on “hockelberry” (Vaccinium?).

This species is one of the earliest to appear in the spring, making itself conspicuous on the wing by its bright yellow wings and rattling stridulation. It is quite common about Toronto in open, sandy, uncultivated lands, especially where these are scattered with low bushes and scrubby trees. I have never seen it about Lake Simcoe, though there are spots there which would apparently make a suitable home for it.

Many American entomologists have, doubtless, been much interested in the accounts published during the past year by Charles Janet on the relations of certain Myrmecophilus Acarians and their hosts. His very interesting papers have been noticed in various English and American journals. Particular attention was paid to two species of Eamasidæ, Discopoma comata and Antennophorus Uhlmanni.

Aspidiotus Dearnessi, n. sp.—♀. Scale suboval, about 2 mm. long, moderately convex, pale gray, more or less concentrically ridged; with the orange-yellow, partly exposed exuviæ quite to one side. Ventral scale thick and distinct. The scales resemble minute oyster-shells.

Andrena Hallii, n.sp.

♀—Length, 14–17 mm. Black, shining; pubescence black with patch on vertex, the prothorax, mesothorax (excepting posteriorly whre pubescence is not so thick and has black mixed with ferruginous, forming a more or less distinct black-appearing band between the tegulæ), scutellum and postscutellum bright ferruginous, thick, entirely obscuring punctures on thorax. Clypeus shining, large quite close punctures, a median line impunctured; antennæ black, third joint equal to fourth and fifth combined; metathorax not shining, closely and more finely punctured; scutellum with two smooth shining spots anteriorly, a few scattered punctures near-by otherwise roughened; postscutellum and metathorax roughened, enclosure triangular, distinctly outlined, carried to a point on posterior face, sometimes faintly and irregularly wrinkled in fore half, last half impunctured. Abdomen without hair bands, a few long scattered hairs on segments 3–4, 5th seg. pubescent and protuberant as is vicina; anal fimbria heavy, black; segments 1-4 depressed posteriorly, the first very slightly if at all, the remainder one-third or one-half of their length; fine scattered punctures on seg. 1–3, remainder impunctured; a sweep of hairs below like vicina. Wings dusky throughout, a violaceous reflection, otherwise like vicina; stigma and nervures piceous or very dark brown. Claws bifid, rufous; spurs black. Basal process of labrum prominent, emarginate.

The article on Diaspis amygdali Tryon, by Professor Webster, in the April issue of this magazine, has left me with the impression that the introduction of this insect to several widely separated sections of the United States has not aroused the apprehension among American entomologists that the advent of a pest of its importance justifies. The quotation from Mr. Tryon's letter to the effect that the insect is neither widely distribued nor destructive in Queensland is too reassuring. It constrains me to emphasize the fact that the species is a highly injurious one in Cape Colony. A brief account of its occurrence here may not be uninteresting.
