The head is small, the forelegs enlarged and adapted for seizing insects, as they creep about the roots of aquatic plants. Hydrometridae. The genus Gerris which represents this family in Maine, is long, narrowing alike towards both ends, being shaped like a wherry, and with their long legs they run over the surface of ponds and streams, moving backwards and forwards with great facility. They are among the earliest spring insects. The following families are terrestial, living for the most part on plants : Reduviidae. Insects with rather long, somewhat flattened bodies ; the beak is much curved ; the head is narrowed behind ; the eyes are very prominent, and the prothorax is much raised in the mid- dle, with a thin, often serrated ridge. The European Reduvius personatus feeds on bed-bugs, its larva and pupa concealed in a case of dust, the better to approach their prey. Ploiaria is very narrow, with very long legs ; it is common in gardens, and is found as late as the middle of November. Nabis ferus is stouter, and very common in gardens. Pentatomidae. This is a large family of insects, of bright colors, and often of large size. The head is received into the large, broad, short prothorax, and the scutellum or the triangular piece at the base of the wings is large and distinct; they are generally oval in form. They are found in shrubs, sucking the leaves, or often seiz- ing some caterpillar with their hooks. De Geer describes the eggs as being generally of an oval form, attached to leaves at one end by a glutinous secretion, the other being furnished with a cap, which the larva busts off when it hatches out. The larvae are rounded oval. Coreidae. These insects are narrower than the preceding group; they are flat above, and beneath convex. They run and fly well, their habits being generally very active.
