They emerge from their hiding places in the early spring, mate, and the female begins to lay eggs before the leaves are out. The eggs are placed sfngl}' or in groups in crevices of the bark of the twigs or in old leaf scars, and, when the leaves have unfolded, upon the leaves thems(dves. The larv» hatch in about two weeks and begin to suck the juices fi'om the leaves and petioles. Th(\v at once commence to excrete honey-dew, and when the insects are extremely numerous the amount of liijuid secreted is enormous and fairly rains from the tree. A black fungus grows on the honey-infested leaves and tree, so that tile whole soon has a smoked appear- ance. In about thirty days the larva becomes adult. Development contin- ues all through the summer, and there may be as many a five broods if the season ])e long enough. It is onl}' known to attack the pear. FAMILY MEMBRACID^. THE BUFFALO { linhalufi Say—f\^. IS.) Upon young fruit trees, particularly the apple, one sometimes sees a series of oval or elliptical scars that disfigure and weaken the })ranches and render them liable to other insect attack. These scars arc the results of the work of a curious insect, the buftalo tree-IiOpper. It is a grass-gi'een, triangular insect that hops and Hies away when disturbed. The pronotum of the thorax is enlarged, as with others of this famil}^, to cover the head and most of the abdomen. The anterior corners of the pronotum project laterally into acute angles.
