There are several species of predaceous insects belonging to the Carabidw, or ground- beetles, which are very active in their habits, and diligently hunt for them and eat them, notably the Green Caterpillar- hunter, Calosoma scrutator (Fabr.)

An Ichneumon fly, Pimpla pedalis Cresson (Fig. 49), is a parasite on this larva, w4iile mites prey upon the eggs, identical with those which feed on the eggs of the common tent-caterpillar. No. 22.—The White-marked Tussock-moth. Orgyia leucostigma (Sm. & Abb.). The orchardist, walking among his fruit-trees after the leaves have fallen, or during the winter months, will fre- quently find a dead leaf or leaves fastened here and there to the branches of his trees ; on examination, these will usually be found to contain a gray cocoon, with in most instances a mass of eggs fastened to it. On breaking into this mass, which is brittle, it will be found to include from three hun- dred to five hundred eggs, about one-twenty-fifth of an inch in diameter, of a white color, nearly globular, and flattened on the upper side. They are placed in three or four layers, the interstices being filled with a frothy, gelatinous matter, which makes them adhere securely together, and over all is a thick coating of the same material, with a nearly smooth grayish-white surface, of a convex form, which effectually.
