Head shining black, glabrous, vertex very minutely punc- 

 tured, the puncturing only visible under a lens ; front impressed 

 with a small oblong fovea ; antennae filiform, four-fifths the 

 length of the body, black, the three upper joints pale yellowish-

 the second and eighth from the suture more elevated than the 

 rest. Outer edges of tibite and the tarsi stained with piceous.

Hab. Amazons, Para, Nauta. 



Very closely allied in form, sculpturing and in the coloration 

 of the elytra to L. vircjata, Lac. ; at once separated from that
