MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 213 



Types. — Holotype, male, in Museum of Comparative Zoology; col- 

 lector and date unknown. 

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



Bahamas: Nassau (M.C.Z.). 



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



Remarks. — This species has a very distinct appearance which is 

 due in part to its flattened dorsum. It diilers from odius by the 

 male characters and from chapini by the less tortuous elytral 

 punctures. 



I have received no record of its habits. 



4. STENUS ODlUS, new species 



Description. — Shining black. Head rather feebly longitudinally 

 biimpressed between the eyes; labrum rather truncate in front; with 

 very coarse and deep but irregular punctures generally separated 

 by one-half their diameter or less; without distinct smooth spaces; 

 without ground sculpture. Pronotum with deep but irregular punc- 

 tures frequently elongate transversely, the intei'vals abrujot and ir- 

 regular; one-eighth longer than wide; widest at middle, moderately 

 narrowed to apex, rather abruptly emarginate behind ; without trace 

 of ground sculpture. Elytra as wide as long, one-half wider than 

 pronotum; humeral callus feeble; punctures as on pronotum but a 

 little coarser and with intervals somewhat flattened; pubescence 

 rather long. Ahdomen strongly margined throughout; with rather 

 small punctures separated by their diameter or more by flat inter- 

 vals; pubescence moderate. Tarsus with fourth segment not at all 

 bilobed; posterior tarsus moderately long; first segment nearly as 

 long as fifth. Male., seventh tergite feebly emarginate, eighth with 

 a very broad but shallow and completely rounded emargination. 

 Female., unknown. Length, 3% mm. 



Type locality. — Cuba, Soledad near Cienfuegos. 



Types. — Holotype, male, in Museum of Comparative Zoology. 



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

 Cuba: Soledad (Darlington, in M.C.Z.). 



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



Remarks. — This species differs from chapini in having the pro- 

 notal and elytral punctures less uniting and tortuous, and in being 

 much more strongly shining. 



I have received no record of its habits.
