Length, 8 mm. Habits.—I took a specimen of this beetlefrom beneath the bark of a large felled \Vcndlandiiitinctoria tree in a clearing on Kadu Hill in theMohnyin forests in Katha. The beetle was fullymature, and appeared to be hibernating in the |,-[(tree. The tree was infested by phitypids (p. 627).9003. I ill! H FAMILY TROGOSITIDAE Family TROGOSITIDAE. Some of the forest forms of this family are readily recognizable owingto their elongate black form, with the large square prothorax and prominenthead and mandibles. Others are not, however, so easy to distinguish. The antennae have often the terminal joints expanded to one side, thus rather resembling the lamellicorn antennae ; the eyes and Beetle. mandibles usually well developed; the elytra, which wholly cover the body, are often prominently striate- punctate, and the legs short with four-jointed tarsi (there are five joints, the first being very small). The grub of this family is elongate, white or yellow (so far as is known),with a black or brown head and prothorax, with well-Larva, developed mandibles, and a pair of calliper-like processes terminating the last segment of the body. The forest species of the family known are predaceous in both the larvaland beetle stages, and the importance of some of the species in keepingdo
