LVI. Anomoglossus Chaucl. 1856. (Gr., "irregular + tongue. ") 



The members of this genus resemble those of Ghlcenms, but 

 differ by the entire absence of any men turn tooth and by the man- 

 dibles being longer and less curved. The entire surface of the ab- 

 domen is punctured and pubescent, the basal line of elytra is angu- 

 late at humerus and the labrum is emarginate. Two species occur 

 in Indiana. This genus and the next are treated by:
