MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 217 



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

 Trinidad: St. Augustine (Darlington, in M.C.Z. and U.S.N.M.). 



Specimens examiried. — I have seen only the three types. 



Remarks. — The slight pronotal protuberance is not equally strong 

 in the three specimens, but this species can be distinguished from 

 jugalis by its much narrower head, by the absence of the whitish 

 pubescent area on the seventh sternite of the male, and by the wider 

 emargination of the eighth sternite of the male. 



I have received no record of its habits. 



9. STENUS HAITIENSIS, new species 



Description. — Shiny black to uniformly picescent. Head very 

 slightly depressed between the eyes but without raised midline ; with- 

 out smooth areas; labrum rounded but feebly truncate in front; 

 punctures moderate but irregular, sometimes separated by nearly 

 their diameter, intervals flat and shiny. Pronotum three-eighths 

 longer than wide, widest just before middle, feebly narrowed before 

 and behind, sides feebly emarginate behind; punctures moderately 

 coarse and deep, irregularly separated by one-half their diameters 

 by feebly convex intervals; without ground sculpture. Elytra one- 

 half wider than pronotum, one-twelfth longer than wide; humeral 

 callus very feeble; punctation similar to that of pronotum but 

 coarser, not at all serial; without ground sculpture. Abdomen not 

 margined; with same type of punctures as pronotum but less coarse 

 and less dense; with distinct ground sculpture on seventh and eighth 

 tergites ; pubescence very short. Tarsi with fourth segment strongly 

 bilobed. Male., sixth and seventh sternites densely and finely punc- 

 tate along middle, seventh very feebly emarginate, eighth with an 

 abrupt triangular emargination more than twice as deep as wide. 

 Female., sixth and seventh sternites punctate as in male, eighth 

 truncate. Length, 4 to 5 mm. 



Type locality. — Haiti, northeastern foothills of the Massif de La 

 Hotte ; elevation 2,000 to 4,000 feet. 



Types. — Holotype and three paratypes in Museum of Comparative 

 Zoology, collected on October 10-24, 1934, by Dr. P. J. Darlington. 

 Two paratypes with same data in the United States National Mu- 

 seum (No. 52493). 



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

 Hispanlola: Haiti, Massif de La Hotte (Darlington, in M.C.Z. and U.S.N.M.). 



Specimens examined. — I have seen only the six types. 



Remarks. — This species differs from jugalis principally as indi- 

 cated in the key, but also in the more abrupt and narrower emargina- 

 tion of the eighth sternite of the male and the feeble development 

 of the spongy area on the seventh sternite of the male. 



I have received no record of its habits.
