Family XIX. COLYDIID.K. 

 TriE CvLixDRic.iL B.VRK 1>ki;tij-;s. 



This family includes a limited nnmbi^r of small beetles of an 

 elongate or cylindrical form, which live beneath the bark of trees, 

 in fungi or in the ground. They are closely allied to the Cueujidie 

 and l)y T'asey have been included as one of nine subfamilies of that 

 family.* 



From their near allies they may be knottti by the following com- 

 bination of characters : antennae 10- or ll-.iointed, rarely S-.jointed. 

 inserted under the margin of the front, sometimes gradually thick- 

 ened, but uisually terminated by a small one- or two-jointed club; 

 elytra entire, always covering the abdomen ; front coxal cavities 

 either open or closed behind, the cox* small, globular; hind coxee 

 transverse, not prominent ; abdomen with five ventral segments, the 

 first three or four grown together; legs short. tibi;e not dilated; tarsi 

 four-jointed, claws simple. The small globular front and middle 

 (■ox;p, till- fiiur-joiutcd tarsi and tlic entire elytra, fornj a trio of 

 eharactei's which readily distinguish the group.
