For several years past, I have tried to obtain eggs from this species by confining the females in small boxes, but without success until this year, when several of these insects were taken during the third week in June, and shut up in boxes and laid aside. They were unfortunately overlooked until the 5th of July, when in one box was found a cluster of 14 eggs which were about hatching, and in another 31 in one cluster, and three detached ones near it. Those in the latter box had not been so long laid, and their colour was unchanged, and from them the follwing description was taken

The present list is based upon a paper on the genus Catocala recently published in the Transactions of the American Entomological Society. The sequence of the species there adopted is here retained, with an unimportant change in a single instance for convenience of reference. The species are grouped according to the colour and design of the hind rvings. Such an arrangement must, to a certain extent, be arbitrary, yet little violence seems to be done to the general affinities of the species by its adoption in this genus.

This huge genus comprehends insects of great variety of size and structure, but unfortunately it has not yet been found practicable to subdivide it. It contains, no doubt, material for several genera, and for the convenience of the student, if for no other reason, its subdivision is the desideratum in microlepidopterology. The young student who finds a micro with the palpi simple or but scarcely at all thickened with scales beneath, the fore wings comparatively narrow, and the hind wings deeply excised beneath the tip, and is told that it is a Gelechia, may well be astonished when he finds a larger insect, with the hind wings not at all excised beneath the tip, and the palpi overarching the vertex, with a large brush beneath the second joint, which may even present some appearance of longitudinal division, and is told thatit,too, is a Gelechia.
