With the constantly increasing activity in applied entomology in America, the necessity for rooms or apartments especially adapted for the study of the development of insects is becoming each year more imperative. The insectary has, in fact, become almost as necessary to the working entomologist as has the laboratory to the chemist. While it is especially true in entomological investigations that one must “study nature where nature is,” it is equally true that on cannot, in all cases, watch with the necessary care and constant application in the fields that he will be able to do in a faily well equipped insectary. Not only can forms be transported thousands of miles while in an inactive state and their development watched at close range, as it were, but eggs and larvae may be brought in during late autumn or winter and studied through their various stages, frequently long before they have appeared outside; and in cases of uncommon or unfamiliar forms this will give the investigator a vast amount of information that he can use to great advantage when the species appears in the fields under a natural condition, perhaps months later.

The following descriptions of species which appear to be additions to our fauna were prepared more than a year ago, but were withheld in the hope that more material might be obtained last season. That hope was, however, not fulfilled; largely, perhaps, be it confessed, through lack of sufficient perseverance on the part of the writer in collecting:

1. Lygocerus pallipes, n. sp.

♀.—Length 1.5—2 mm. Black, finely punctulate and sparsely pubescent. Mandibles and palpi yellowish; antennae balck, except the scape at base and beneath; scape stout, first joint of flagellum about half as long as scape, second as long as pedicel, remaining joints subequal. Legs, including coxae, yellow. Wings subhyaline, stigma large, yellow. Abdomen stout, pointed at tip.

The following notes relate in large part to additions recently made to the Canadian fauna through the activity of collectors in the Dominion. several species which their possessors were unable to identify by means of the tables have been submitted to me, and, proving new to the Canadian lists, are incorporated in these pages, that students may have access to the descriptions. The families are taken up in the order of their treatment in the Canadian Entomologist.

I have been much interested in reading the notes upon the odour of scale insects by Professors Webster and Cockerell in the January and February issues of this journal. Durning my inspections in orchards and nurseries I have frequently detected the odour emitte by Aspidiotus perniciosus, mentioned by Webster, especially where the trees were badly infested, and have wondered what relationship it bore to the species. I have detected the most pronounced odours, however, in the genera Chionaspis and Lecanium. The odour produced by the Euonymus scale, Chionaspis euonymi, is very unpleasant to some persons. It is most marked upon badly infested, freshly cut twigs. If they are left in a tightly closed room for a few hours, the air will become very foul.

In the Canadian Entomologist, XXVI., pp. 69, 70, Mr. Geo. A. Ehrmann described as new three West African moths. Very recently this gentleman has been so obliging as to forward his types to me for examination. I should like to put on record a few observations on them for the benefit of students of the African fauna.

Aleurodes graminicola, n. sp.

Egg.—Size, .25x.13 mm.; uniformly brownish in colour; unmarked; oblong, truncate at base; pedicel short, attached to one corner; eggs held nearly upright on leaf by short pedicel and truncated end.

Larva.—Length, .7 mm.; width, .3 mm.; oblong-elliptical in shape; colour, yellowish-white; eye spots reddish. There is a marginal fringe all around of white cottony waxen threads. No marginal rim, and but faint crenulation. In other respects, essentially as in pupa-case.

Epizeuxis gopheri, n. sp.

Ground colour a very pale mouse-gray, the wings with the appearance of being thinly scaled. On the thorax is a slightly warmer, more brown or reddish tinge, while the under side is darker and somewhat more smoky throughout. Primaries with all the lines diffuse and vague, except the s. t., which is distinct and very sharply dentated. The basal line is wanting. The t. a. line is pale, without defined margins, and crosses the wings with scarcely an out-curve. The t. p. line is yet more feebly marked except on the costa, and crosses the wing with a feeble outcurve, a little more marked than the outer margin of the wing itself. In the male this line seems to be better defined than in the female. The s. t. line is whitish, distinct, and irregularly toothed in both directions; that is, inwardly as well as outwardly — as a whole keeping al about the same distance from the outer margin throughout. The ordinary spots are very feebly marked; the orbicular a faint yellowish dot, and the reniform a somewhat larger blotch of the same colour; but in both cases indefinite. The secondaries are distinctly paler, more washed out and becoming almost whitish at the base.
