 Long. 2|lin, 



Hah. Bahia (Reed). My collection. 



Head not longer than broad ; clypeal ridge raised but not 

 well-defined laterally ; antennte equal to the body in length, fili- 

 form, the second joint very short, the third slightly longer, the 

 fourth longer than the preceding two united ; the two or three 

 basal joints uigro-piceous, the ninth and tenth white, the rest 

 black. Thorax about one-fourth broader than long ; sides slightly 

 rounded anteriorly, abruptly sinuate just behind the anterior angles, 

 nearly straight and parallel posteriorly ; disk shining, impunctate, 

 distinctly bifoveolate. Elytra subelongate, slightly dilated pos- 

 teriorly, plicate on the sides, the subhumeral costa ill-defined, 

 bounded within by a broad shallow sulcation ; surface rather 

 coarsely punctured, faintlj' wrinkled on the middle disk.

Long. 2f lin. 



Hah. Upper Amazons. A single specimen in my 

 own collection. 



Head not longer than broad, triangular ; clypeal ridge ill- 

 defined; antennee equal to the body in length, the second joint 

 short, moniliform, the third one-half longer, the fourth longer than 

 the preceding two united; the three lower joints obscure piceous, 

 the ninth and tenth yellowish white. Thorax scarcely one-fourth 

 broader than long ; sides straight and parallel from the base to 

 beyond the middle, thence rounded and converging towards the 

 apex ; disk nitidous, impunctate, impressed with two large shallow 

 fovese. Elytra narrowly oblong, convex, slightly flattened along 

 the suture, rather strongly and closely punctured; outer disk 

 plicate ; each elytron with the basal and outer margins piceous, the 

 piceous colour on the lateral border becoming paler along the outer 

 edge, being scarcely darker than the disk itself.
