ones. Prothorax narrowed behind, usually deeply furrowed. 

 Elytra truncated behind. Abdomen broadly margined. Legs 

 rather long ; intermediate coxse remote; tarsi 4:5:5, first joint of 

 the posterior pair elongate. 



This genus is widely distributed, but is more numerously repre- 

 sented in the new than in the old world, a large proportion of the 

 species being found in tropical America.
