330 PROCEEDINGS OF THE NATIONAL MUSEUM vol. ns 



Type, male, John A. Wilcox collection, from Caura River, Suapmi-e, 

 Venezuela, collected by E. A. Klages, March 20 and April 14, 1899; 

 paratype, female, USNM; one female specimen, MCZ, from Rio 

 Madeu-a, Brazil, collected by Mann and Baker. 



Remarks: In the more heavily marked specimens this species 

 resembles Neobrotica coeruleofasciata Jacoby but that species is not so 

 strongly costate and has metallic colored spots and is somewhat 

 smaller. The head of N. coeruleofasciata has no such depression in 

 the lower front as in this species.

 Nov. 15, 1874; one specimen, John A. Wilcox collection, from Caura
