MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 429 



tures. Elytra densely and rather finely punctate. Abdomen sparsely 

 punctate, especially on eighth tergite. Male^ unknown. Female., 

 (sternites not modified). Length, 6 to 7 mm. (From Fauvel and 

 Bernhauer.) 



Type locality. — Martinique. Of ea'/'mhts, Guadeloupe. 



Types. — Presumably in the collection of Blanche Rancin, Caen, 

 Trance. Of eximius, presumably in the collection of Dr. Bernhauer. 



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



Guadeloupe: (Bernhauer, 1917, hs cximius). 

 Martinique: (Fauvel, 1901; Leng and Mutchler, 1914). 



Specimens examined. — I have seen no examples of this species. 



Remarks. — There seems to be little doubt that these two names 

 represent a single species. It is distinguished by the blue color of 

 the elytra alone and by the extent of the pale area at the apex of the 

 abdomen. 



I find no record of its habits.

 any depressions on front of vertex; with moderate punctures very 

 sparse, absent on center of vertex; without ground sculpture. Pro- 

 notum over one-fifth longer than wide, widest at anterior third, 

 feebly sinuately narrowed posteriorly, with all angles rounded; 

 dorsal series of five punctures, and with about seven lateral punc- 

 tures ; with very fine strigulose ground sculpture. Elytra with mod- 

 erately coarse punctures separated by less than their diameter by 

 feebly convex intervals; with only a trace of ground sculpture. 

 Abdomen rather finely and sparsely submuricately punctate; with 

 rather indistinct transversely strigulose ground sculpture. Male, 

 eighth sternite with an abrupt rounded median posterior lobe nearly 

 as long as wide and about one-fifth as wide as apex of segment. 

 Female, unknown. Length, 5V2 ^nm.

 north of Yauco, elevation about 3,000 feet. 



Types. — Holotype, male, U.S.N.M. No. 52459, collected by me on 

 October 3, 1935. 



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



Puerto Rico: Maricao ( Blackwelder station 47B). 



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

 Remarks. — This is one of those species which is near the dividing 

 line between Belonuchus and Philonthus. It has the united gular
