wide, with sides nearly parallel, base broadly rounded ; dorsal series of 

 five punctures, and with about seven lateral punctures; ground sculp- 

 ture as on head. Elytra with rather coarse and dense punctures, some- 

 times not sharply outlined and in transverse rows; without ground 

 sculpture. Abdomen with sparse and moderately coarse punctures, 

 generally excavated behind; without distinct ground sculpture, but 

 somewhat iridescent. Male^ eighth sternite with an abrupt rounded 

 emargination twice as wide as deep. Female^ eighth sternite rounded. 

 Length, 8 to 9 mm. 



Type locality. — Dominica, Hillsboro Estate, at mouth of the Layou 

 River, Leeward side. 



Type,^. — Holotype, male, and four j^aratypes, U.S.N.M. No. 52462, 

 collected by me on June 2, 1936. One i)aratype in my own collection. 



Records. — The following is the only record known to me : 



Dominica: ( Blackwelder station 237). 



Spechnens exami7ied. — I have seen only the six types. 



Remarks. — This species is distinct by its rufescent color, by its male 

 characters, and by the parallel pronotum. The six specimens are very 

 uniform in these respects and seem to preclude the possibility of the 

 color being due to immaturity. 



The types were found in rotting cocoa pods.
