FAMILY TROGOSITIDAE 



Family TROGOSITIDAE. 



Some of the forest forms of this family are readily recognizable owing 

 to their elongate black form, with the large square prothorax and prominent 

 head 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 larval 

 and beetle stages, and the importance of some of the species in keeping 

 down the numbers of wood- and bark-boring pests is very considerable. The 

 family will well repay a close study on the part of the forester.
