Our correspondent probably refers to the raspberry cane borer, Oberea Bimaculata, Fig. 678, from Saunders' Insects Injurious to Fruits, shows the full-grown beetle, and renders a description here unnecessary. It is one of the long-horned family (Cerambycidae) and immense family num- Fig. 678. , . v 3 ' . 3 benng some 4,000 species, many of them destruc- tive borers, which live and burrow in wood of plants and trees, , the Locust tree borer, Clytus Robinia, Fig. 679, the apple tree borer, Saperda Candida, Fig. 680, etc. * Fig. 679. The perfect beetle flies about during this month, and the female deposits her eggs in the tender part of the growing tip of the raspberry cane. She first checks the rapid growth of a portion of the cane, to make the place more and more secure in which to deposit an egg; and this she does artfully by first girdling the cane in two places, and then thrusting her eggs in it about midway between the rings. When the young larva hatches out it burrows its way down the centre of the canes, continuing its destructive opera" tions until about the end of August, when it pupates and re- mains until the following June, when the beetle gnaws its way out, to repeat the round its parent has done before it. This insect may easily be kept down by a little watch- fulness for the affected canes will droop and wilt, and if cut below the part affected and burned, they will give little Fig. 680.
