Long. 3 lin. 



Ilah. Brazil, Rio Janeiro (Squire). My collection. 



Head triangular, slightly broader than long ; eyes large, rotun- 

 date ; antennae longer than the body, filifoi-m, the second and third 

 joints very short, moniliform, the fourth more than twice the 

 length of the iireceding two vmited. Thorax nearly one-third 

 broader than long ; sides nearly straight and parallel, scarcely con- 

 verging at the apex ; disk nitidous, deeply bifoveolate. Elytra 

 sv;belongate, scarcely dilated posteriorly, rather coarsely and 

 closely punctured ; the entire limb of each (the base excepted) 

 edged with black. 



The solitary specimen known to me (in which the 

 terminal joint of the antennse is broken off) is a male ; 

 the female is probably broader, with shorter antennae 

 and smaller eyes.
