Long. 1 lin. Hah. — Brazil. 



Head rotundate, vertex smooth, impunctate; encarpas 

 obsolete ; carina broad, its apex angulate, slightly raised,

 half longer than the third. Thorax three times as broad 

 as long; sides nearly straight, converging from base to 

 apex, anterior angle obliquely truncate, its outer edge 

 l^roduced slightly outwards; upper surface finely but not 

 closely punctured. Elytra broader than the thorax, regu- 

 larly rounded at the apex, distinctly punctured. 



Eupleciroscelis nigripennis. 



Breviter ovata, valde convexa, fulva, nitida, thorace 

 rufo-fulvo, Iffivi, minute punctato; elytris nigris, confuse, 

 tenuiter punctatis. 



Long. 1^ lin. Hab. — Para. 



Head subtrigonate ; vertex and front narrow, longitudi-
