Head rounded, inclined forward ; interocular and inter- antennal spaces generally smooth, but sometimes with a carina ;. Fig. 47.— Psylliodes tcnebrosns, Jac. Lateral view of part of hind femur, tibia and tarsus, showing the point of insertion of the tarsus in the tibia. surface generally punctate. Eyes large, convex, more or less oval. Antennae composed of ten segments, generally thin, moderately long, extending to the middle of the elytra ; their roots are nearer to the eyes than to each other ; basal segments elongate, slender, their relative lengths varying; apical segments slightly thickened, the last segment pointed. Prothorax broader than long, usually somewhat narrowed in front, anterior margin straight, lateral margins feebly rounded, sides declivous, surface convex and generally punctate. Scutellum small, almost an equilateral tri- angle. -Elytra oblong-ovate, narrowed behind, somewhat broader at the base than the prothorax, very regularly punctate-striate ;.
