Family NITIDULJD/E. 



Sap beetles as a rule, although some live in fungi and others in or on 

 dry animal or vegetable matter. In a general way they may be classed 

 as scavengers, and have the short, chunky antennal club usual to such 

 species. The majority are more or less flattened, usually broad in pro- 

 portion to their length and some of them with somewhat abbreviated 

 elytra, exposing the end of the abdomen. Sap beetles are most abundant 

 in late fall on tree stumps cut in spring or on over-ripe and decaying 

 fruits.
