Hab. — Upper Amazons. 



Similar in its oblong form, colour, and sculpture to 

 D. harhipes, but differs in the armature of the hind 

 femora of the males, which have also no trace of the 

 hairs which distinguish that species. Two males and one 

 female.

Hah. — Ega, Amazons. 



Distinguished by the usual short inner carina of the 

 elytra being continued, although less elevated, in com- 

 pany with a well-marked stria to the apex of the elytra. 

 The elytra are uneven, with shallow wrinkles, besides 

 the rows of foveas which are much larger and more vague 

 than in the common Brazilian D. morhiUosiim. I do not 

 find a male example in my collection ; two females 

 agree exactly in their specific characters.
