Onr readers will recognize at once in figure 8, (Lachnosterna quercina) the common May-bug in its different stages. I shows the chrysalis; 2 the larva, and 3 and 4 the perfect insect. It appears in some years in vast nnmbers, and is greatly complained of, whilst in other seasons it is comparatively rare. This depends chiefly on the long duration of its developement. The insect flies with a humming noise, so that one is aware of its approach at the distance of some yards.

The butterflies collected by Mr. Couper have been already enumerated in the “Bulletin of the Buffalo Society of Natural Sciences.” They were : Vanessa atalanta, Argynnis atlantis, Phyciodes tharos, Glaucopsyche Couperi, Cyaniris lucia, Ganoris oleracea var. borealis, Papilio brevicauda and, Cycloypides mandan. The moths, as far as the Geometridæ, have been determined by me and were as follows

This genus, though closely allied to Stilbosis, Walshia, Elathista, &c., differs from them somewhat as to the palpi, and yet more as to the neuration of the wings. In the neuration it is near Stilbosis, but in many respects is nearer Walshia.
