STENID.E. — OXYPORUS. 305 



entire, acute : labrum deeply notched in the middle : head suborbiculate, 

 large; et/es lateral, prominent: thorax short, truncate, with the sides de- 

 flexed: elutra somewhat depressed, shoulders gibbous: abdomen, short, 

 ovate : legs moderate : tihicE slightly ciliated, armed at the apex with 

 minute spurs : tarsi short, five jointed. 



The genus Oxyporus, the natural situation of which is very- 

 doubtful, may be known from the other genera of the family with 

 which it is here associated by having the labrum deeply notched, and 

 the labial palpi securiform ; the antennae are very short and clavate, 

 the club being compressed: the mandibles are long and pointed, and 

 like the Paederi the species are generally of gay and lively colours ; 

 they inhabit fungi.
