The life history of the Purblind Spinx, Smerinthus myops, Fig. 3, is very similar to that of the species just described. It appears in the perfect state also in June and July, The moth is very handsome. The head and thorax are chocolate brown with a purplish tinge, the thorax is striped with yellow and the abdomen brown marked with yellowish spots. The fore wings are angulated and excavated on the hind margin, and are or- namented with bands and patches of black on a chocolate-brown ground, The hind wings are dull yellow with the outer half a rich brown, and have an eye-like spot to- wards the inner margin, black with a pale blue centre. The caterpillar much resembles Fig. 2. It is green with two rows of reddish brown spots on each side and six oblique yellow lines, with two shorter lines of the same colour on the anterior segments. The head is bluish green, margined with yellow, and the curved horn at the tail green, tinged with yellow at the sides. When full grown it measures about two inches in length, and is nearly cylindrical in form. It feeds on the leaves of the cherry tree, both the wild and cultivated varieties. The insect passes the winter in the pupa state under the earth ; the chrysalis is smooth and of a dark brown colour. Both these insects are comparatively rare, and have never, as far as we know, appeared in sufficient numbers to prove injurious to the trees- on which they feed. Pulvinaria Innumerabilis—Rathvon. This insect, which has commonly been known as the Grape-vine Bark-louse, might with perhaps greater propriety be now designated the Maple-tree Bark-louse, for the reason that it has been more frequently found on maples, and has inflicted more injury on these trees than it has on grape-vines. The great abundance of this insect during the past season has called general attention to it and elicited many enquiries in reference to its history and habits; indee
