Family HETEROCERIDiE. 



These beetles are oblong, convex, densely clothed with short silken pubes- 

 cence. The thorax is almost square, the corners rounded, head small with the 

 mandibles projecting prominently. They are yellowish in color mottled with 

 blackish spots or bands, and live in galleries in sand or mud along the banks of 

 ponds, streams or ditches. They fly at night and are often attracted to light. 

 The larvae are found with the beetles and are supposed to feed upon the decayed 

 vegetation or microscopic organisms found there.
