MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 239 



RemarJiS. — This is an imiisually small and obscure species, which 

 shows some variation in certain characters. Its lengthy synonymy 

 is due more to the confusion in generic names than to anything 

 else, although most of the synonyms have been recorded only once 

 each. It is distinguished from our other species by the modification 

 of the seventh sternite in the male and by the dense sculpture. It 

 belongs in the subgenus SciochareUa as herein defined. 



The name atratula is listed as a synonym on the authority of Fau- 

 vel. The two Casey species are placed as sjnionyms after a careful 

 examination of the types. Sharp's two species are included on the 

 basis of the original descriptions and a note by Fauvel. 



My specimens were found in dung, in decaying cocoa pods, in a 

 pile of dead grass, and flying at dusk.
