not rounded behind although posterior angles are rounded; eyes large, 

 at about their length from base; labruni minutely bidenticulate, indis- 

 tinctly dentate at outer angles; umhilicate punctures moderate, some- 

 limes elongate in front; vertex with a smooth median area; without 

 ground sculpture, Pronotvm as wide as long, five-sixths as wide as 

 head; widest at anterior angles, sides distinctly emarginate in front, 

 distinctly arcuate posteriorly; with a distinctly elevated smooth middle 

 band, umbilicate punctures dense, with intervals wider and shiny just 

 behind middle on each side but not forming a distinct smooth area; 

 without ground sculpture. Elytra scarcely' wider than long, a trifle

Type locality. — Jamaica, Chester Vale district. 



Types. — Unique type in the collection of Dr. Cameron. 



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



Jamaica: (Leng and Mutchler, 1917), Chester Vale (Cameron, 1913), Spanish 

 Town (Blaekwelder station 377), Santa Cruz ( Blackwelder station 421), 

 Milk River (Blackwelder s(;ition 415), TiiniryvilJe ( Blackwelder station 428), 

 Blue Mountains (Darlington, in M.C.Z. and U.S.N.M.), Kingston (Darling- 

 ton, in M.C.Z. ). 



Specimens examined. — I have seen the unique type in Dr. Cameron's 

 collection, 11 specimens from the Museum of Comparative Zoology, 

 and 8 examples collected by Chapin and Blackwelder in February 1937. 



Reinmhs. — Tliis species is described from specimens I compared with 

 the type. It is chiefly distinguished by its elytral punctation and male 

 characters. 



My sjjecimens were caught flying at dusk.
