A gall from a Golden-rod, out of which a moth of this species has escaped, is figured in Second Report Insects of Missouri, page 134. In the accompanying description the author says: “There are some doubts in my mind as to whether it is a real gall-maker, or an inquiline, or an intruder on my true Solidago gall-maker (Gelechia gallœsolidaginis).” “My reasons for thinking this insect an intruder are, first, because if it were a true gall-maker, we should naturally expect to find its gall more common; second, because on several occasions I have found within the Gelechia galls,a pale worm very different from the true gray gall-making larva.” In the Can. Ent., x., 202, I asserted, perhaps too abruptly, that this moth is not an intruder, but the cause of the gall in which it resides during the larval and pupal states. In the paper cited I gave my reasons for this conclusion, reasons which I considered sufficient, namely: that it was very abundant about Buffalo, that I had followed the larvæ in the galls from soon after hatching and soon after they had pierced the stem until final transformation, and that their gall habits were somewhat characteristic.

Egg—Nearly globular; the surface smooth under a low power, but under a high one, thickly covered with shallow depressions, which are irregular in size and also in form, being pentagonal, rounded or oval; color pale green. Duration of this stage about 6 days.

Young Larva.—Length .12 inch; cylindrical, nearly even, tapering a little posteriorly, the last segment bluntly forked; color delicate green; over the surface many white hairs, and among these are black clubbed hairs disposed in longitudinal rows, four on the dorsum of each segment, two in front, two in rear; feet and legs green; head large, about twice as broad as any body segment, sub-globose, a little depressed at top; on each vertex a short semi-ovoid appendage, at the top giving out two divergent black hairs; just below vertex, on the front, is a similar smaller appendage with single hair, and on the side half way down is a second; color black. Towards the end of this stage the color of body changes to decided green, and several longitudinal stripes appear; on either side of a dark green medio-dorsal stripe is a whitish one, a similar one on middle of side and another along base. Duration of this stage about 8 days, but depending on the weather.

Nearly a year ago my attention was especially called to the insects which prey upon woolen fabrics, and which are generally known as “clothes moths.” In going over the literature of the subject at that time and comparing it with the notes which I had made from time to time, I became convinced that what we have in our books pertaining to these insects is very imperfect and faulty, and that there was need of a thorough revision. This held true, not only of the species which destroy clothing, but also of many other species in the family Tineidœ.

I therefore obtained, by purchase and otherwise, as large a collection as possible from all parts of the United States—over twelve hundred specimens—and sent them to Lord Walsingham, in England, for comparison with the European species. This collection has just been returned to me, and the notes and descriptions which his lordship has made on it will soon appear in the Trans. Am. Ent. Soc.

Copablepharon Longipenne, n. s.

Eyes naked; tibiæ spinose. Fore wings clear light buff yellow with an outer line merely a succession of minute dots, at usual place of s. t. line. Hind wings fuscons with pale fringes. Head and thorax yellow; pectus and palpi whitish. Beneath the whitish wings are clouded with pale fuscous. A little slighter than Absidum (= Aedophron grandis of Strecker). Montana Coll. B. Neumoegen, Esq.

Copablepharon Subflavidens, n. s.

Eyes naked; tibiæ armed; fore tibiæ with a very slight claw in addition. Primaries pure light yellow, immaculate. Hind wings pure white, immaculate. Abdomen white; white beneath. Montana, Coll. B. Neumoegen, Esq. Size of the other species. C. Album is also in the collection before me.

Recently I had the opportunity of watching in a live box, under a low power of the microscope, the seizing and devouring of some plant-lice by the larva of an undetermined species of Chrysopa, and was interested in the manner in which it emptied the body of its victims. The jaws are large, hooked, pointed and tubular, with a small opening at or near the points. Approaching its prey the body of the Aphis is grasped by the hooked mandibles which at the same time pierce it. The Chrysopa larva remains stationary, and proceeds to pump its victim dry. At the base of each of the mandibles the integuments are dilated into a sac-like form capable of expansion and compression at will, a portion of the thorax is similarly constructed, and it is by the repeated dilating and compressing of these sacs that the fluid contents of teh body of the Aphis are transferred through the tubular mandibles to the stomach of the Chrysopa larva.
