. Insects injurious to fruits. Illustrated with four hundred and forty wood-cuts. Insect pests. ATTACKING THE LEAVES, 83 thirds of its length, followed by a small yellow patch, which is succeeded by a larger black spot, centred with a crescent of blue atoms, and bounded below by an irregular reddish spot, margined within with yellow. The hind wings terminate in two long black tails edged on the inside with yellow. The body is black above, margined with pale yellowish; below, yellowish streaked with black. The under surface of the wings resembles the upper, but is paler. This insect passes the winter in the chrysalis state, and ap- pears first on the wing from the middle to the end of May, but becomes more plentiful during the latter part of June and early in July. The eggs are deposited singly on the leaves of the apple and other trees and shrubs on which the larva feeds; they are about one-twenty-fourth of an inch in diame- ter, nearly round, of a dark-green color, with a smooth sur- face. In about ten or twelve day& the eggs begin to change color, becoming darker, and growing very dark just before the escape of the larvse. The very young caterpillars are black, rouochened with small brownish-black tubercles, with the first segment thickened, of a dull, glossy flesh color, a prominent fleshy tubercle on each side, and a patch of white on the seventh and eighth segments. When full grown, it appears as in Fig. 81. It is then from an inch and a half to two inches long, with a rather large reddish-brown head, and a green body, which is thick- est towards the head and tapers posteri- orly. On the an- terior segments the green is of a darker shade, but paler on the sides of the body, and partly covered with a whitish bloom. On the front edge of the first segment is a raised yellow fold, which slightly overhangs the head, and from which, when irri- tated, the larva protrudes a yellow, fleshy, forked organ, at Fig. Please note that these images are extracted from
