290 BULLETIN 182, UNITED STATES NATIONAL MUSEURI 



impression on each side near base ; punctures fine and close, much finer 

 than on head. Elytra finely and closely but less distinctly punctured 

 than pronotum. Male^ unknown. Female (presinnably with ster- 

 nites unmodified). Leno:th, 2>% mm. (From Cameron.) 



Type locality. — Grenada, Balthazai*. 



Types. — Unique female in the British Museum. 



Records. — ^The following are the records, known to me : 



Cuba: Aguadores, in Oriente (Darlington, in M.C.Z.). 



Grenada: (Cameron, 1913; Leng and Mutchler, 1917; Scheerpeltz, 1933; British 

 Museum). 



Specimens examined. — I have seen only the unique type and one 

 specimen from the Museum of Comparative Zoolog}', as explained 

 below. 



Remarks. — Although the original description does not mention the 

 presence or absence of ground sculpture on the head, I assume that it 

 is not present. This species belongs in the subgenus Scopaeus s. str. 



Since the above description was written I have received one ex- 

 ample from Cuba that agrees very closely with it. The specimen is a 

 female and shows the following additional characters: Head with- 

 out gi'ound sculi)ture ; eyes separated from base of head b}' two and a 

 half times their length; pronotum unusually rounded but much de- 

 pressed, Avithout posterior depressions, although the disk is flattened; 

 length, 3 mm. 



I find no record of its habits.
