MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 49 



Schwarz recorded this species (on specimens in the United States 

 National Museum) "on ceiba" (silic cotton tree). I collected it from 

 under bark of logs of the same tree, in rotten coconut husks, in old 

 banana stalks, and in rotten cocoa pods. Specimens from the Museum 

 of Comparative Zoology are labeled "fermenting palm" and "bark 

 of log."

Description. — Piceous to rufopiceous, elytra rufotestaceous. Head 

 flat, with supraantennal tumescences very feeble, merging posteriorly 

 into the flat surface of the vertex, separated from the feebly convex 

 central clypeal area by a well-impressed U-shaped line which curves 

 outward at the sides and is continued as a black line to the side mar- 

 gins; sparsely and rather finely punctate, and distinctly strigulose 

 throughout (more finely and densely on the clypeus) ; gular sutures 

 impressed, leaving gula convex through most of its length. Prono- 

 tum. quadrate, sides feebly rounded; width to length as 3 to 2; mid- 

 line feebly impressed and irregularly punctate; lateral sulci coarse, 

 extending nearly to middle of length; sparsely and finely punctate 

 with scattered larger punctures especially near the depressions, obso- 

 letely strigulose at the sides and base only. Elytra with striae finely 

 punctate, intervals each with an irregular row of moderately fine 

 punctures; sixth stria represented by an irregular band of punctures.
