MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 257 



Remarks. — This species is reacUh^ distinguished by its dense ground 

 sculpture. Some variation has been observed in the impressions and 

 channeling of the pronotum. It belongs in the subgenus Stilomedon 

 s. str. 



The examples from Cuba were taken "in ceiba" (silk cotton tree) 

 and the one from Jamaica flying at dusk.

Description. — Rufous, elytra and abdomen sometimes rufotesta- 

 ceous. Head not emarginate behind, hind angles broadly rounded; 

 eyes small, at nearly twice their length from base; labrum not de- 

 cidedly emarginate, with median denticle not very distinct, additional 

 pair rather widely separated, large at base but acute and rather 

 long; gular sutures very close but feebly converging posteriorly; 

 surface with dense umbilicate punctures, the intervals frequently 

 united in rows, without ground sculpture. Pronotwn with sides 

 rather strongly converging posteriorly; with two feeble longitudinal 

 impressions posteriorly on disk along middle ; midline not distinctly 

 channeled; punctures not umbilicate but moderately coarse, usually 

 separated by less than their diameter; without ground sculpture ex- 

 cept at posterior angles. Elytra with indistinct punctation, which is 

 evidently the result of the flattening of small tuberculi with the punc- 

 tilio on top; without distinct ground sculpture. Ahdomen rather 

 densely and finely but asperately punctured; with rather long and 

 dense pubescence. Male., seventh sternite unmodified, eighth with a 

 very broad rounded emargination. Female., sternites unmodified. 

 Length, 314 to 4 mm. 



Tijpe locality. — "Amazons" (= Amazon Valley, Brazil). 



Types. — "Two males in the British Museum" (according to the 

 original description, but a note in the collection of the British 

 Museum says, "Type not found." I found no South American exam- 

 ples in that collection).
