58 MANDIBULATA. — COLEOPTERA. 



bisinuated : scutellum minute : elytra short, broad, depressed on the back, 

 each rounded at the apex, and a little shorter than the abdomen : legs rather 

 short and stout; femora unarmed; tibia slightly compressed, truncate at 

 the apex, which is a little spinose. 



This genus chiefly difl"ers from Tychius by its depressed back, 

 and the produced posterior margin of the thorax ; and by the struc- 

 ture of the antennae, the funiculus of which is always 6-jointed: 

 like Tychius, the body is very densely clothed with compact short 

 pubescence : — the species appear rare in Britain.

 obsolete fuscous blotch, edged posteriorly with whitish, on the back : legs
