MONOGRAPH OF WEST IXDIAK STAPHYLINIDAE 253 



sculpture ; pubescence dense and distinct. Ahdomen very minutely and 

 densely punctulate and pubescent; with indistinct ground sculpture. 

 Male, seventh sternite with two emarginations separated by a broad 

 feebly rounded lobe and bounded laterally by two broadly triangular 

 processes; eighth with a deep rounded emargination nearly twice as 

 wide as deep. Female, unknown. Length, 6^^ mm. 



Type locality. — Trinidad, 5 miles west-southwest of Manzanilla 

 junction on the Plum Road. 



Types.— Ro\oiy]yQ, male, U.S.N.M. No. 52399, collected by me on 

 December 18, 1935. 



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



Trinidad: Manzanilla (Blackwelder station 104A). 



Specimens exatnined. — I have seen only the unique type. 



Remarks. — This species is distinguished principally by the male 

 characters. Three specimens in the British Museum under the name 

 Medon latro Sharp are probably this species, although I have not 

 examined the male characters. They were taken at Caparo, Trinidad, 

 by Klages in June 1914. 



It is possible that this species or the following one is the same as 

 A. latro Sharp, but I am not able to form an opinion without seeing 

 the male characters of the type. The latter is in the British Museum 

 and is mounted undei* glass. 



The type was collected from decaying cocoa pods.

 the sexes; very irregularly but distinctly punctate with dense pubes- 

 cence, posteriorly becoming somewhat tuberculate, more dense, and 

 with some ground sculpture. Pronotum with distinct smooth mid- 

 line, somewhat elevated; with dense but discrete tuberculi bearing 

 dense pubescence, and mixed with ground sculpture at sides posteri-
