. Insects injurious to fruits. Illustrated with four hundred and forty wood-cuts. Insect pests. 26 INSECTS INJURIOUS TO THE APPLE. The mature larva (Fig. 11)^ which attains its full growth early in April, is about two and a lialf inches long, nearly four-tenths of an inch across about the middle, tapering â piQ^ 11, slightly towards each extremity. The head is broad, brownish, and rough above; the jaws very strong, curved, and pointed; the terminal seg- ment of the body blackish, roughened with small pointed tubercles, with a deep semicircular notch at the end, and armed at the sides with small teeth, the two hindermost of which are long, forked, and curved upwards like hooks; under this hinder segment is a large fleshy foot, furnished behind with little claws, .and around the sides with short spines; it has six true legs,âa pair under each of the first three segments. Early in spring the larva casts its skin and becomes a chrysalis, and in due time there emerges from it a perfect beetle. This beetle, when placed upon its back on a flat surface, has the power of springing suddenly into the air, and, while moving, turning its body, thus recovering its natural position. This unusual movement combines with its curious prominent eye-like spots to make it a constant source of wonder and interest. Since it feeds only on decaying wood, it scarcely deserves to be classed with destructive insects; yet, being occasionally found in the wood of the apple-tree, it is worthy of mention here. No. 8.âThe Rough Osmoderma. Osmoderma scahra (Beauv.)- This insect, also, lives in the larval state in the decaying wood of the apple, as well as in that of the cherry, con- suming the wood and inducing more rapid decay. It is a large, white, fleshy grub, with a reddish, hard-shelled head. In the autumn each larva makes for itself an oval cell of fragments of wood, cemented together with a glutinous ma-.
