It attacks also the pear, the plum, and sometimesthe peach. In the Southwestern States it begins to appearduring the latter part of May, and is found during most ofthe summer months; in the Northern States and Canada itstime of appearance is June and July. It does not confine itsattacks to the base of the tree, but affects the trunk moreor less throughout, and sometimes the larger brandies. The eggs, which are yellow and irregularly ribbed, artvery small, about one-fiftieth of an inch long, of an ovoidalform, flattened at one end, and are fastened by the female. and the sunny South.

The young larva soonhatches, and, having eaten its way through the bark, feedson the sap-wood within, where, boring broad and flattishchannels, a single specimen will sometimes girdle a small the larva approaches maturity it usually bores into themore solid wood, working upward, and, when about to changeto a pupa, cuts a passage back again to the outside, eatingnearly but not quite through the bark. Within its retreatit changes to a pupa (Fig. 4, 6), which is at first white, butgradually approaches in color to that of the future beetle,and in about three weeks the perfect insect emerges, and,having eaten through the thin covering of bark, escapes androams at large to continue the work of destruction. The mature larva (Fig. 4, a) is a pale-yellow leglessgrub, with its anterior en
