MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 95 



ments smootli, eighth sternite feebly lobed at center, ninth convex. 

 Length, 2^4 "i"^- 



Type locality. — Trinidad, about 5 miles southwest by south of 

 Manzanilhi junction on the Phun Mitan Koad, county of St. Andrew, 

 ward of Turure. 



Types'. — Holotype, male, and paratype, female, U.S.N.M. No. 52370, 

 collected by nie on December 18, 1935. 



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



Trinidad: Maiiztuiilla (Blackwelder station 103A). 



Specimens examined. — I have seen only the two types. 



Remarks. — This species seems to be very similar to 0. sidcifer 

 Fauvel from Venezuela but differs from his description as follows: 

 Clypeus dentate in both sexes, pronotum with five sulci, elytra feebly 

 rugose at base ; size less than 2V2 i^iii^- These differences may be due 

 to omissions in Fauvel's description, but until the two species can 

 be directly compared I think it better to treat them as distinct. 



My specimens were collected from rotting cocoa pods.
