MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 221 



Cuba: (Dyer, in the U.S.N.M.). 



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



Remarks. — This species is distinguished from adamsoni by the rela- 

 tive length of the pronotum and by the flatter intervals between the 

 pronotal punctures. It differs from cubanus in its size, in having 

 the abdominal segments not very abruptly constricted, and in having 

 the smooth areas of the head poorly defined. 



I have no record of its habits. 



14. STENUS CUBANUS, new species 



Description. — Piceous. Head distinctly biimpressed between the 

 eyes ; with an elevated central smooth area, another at upper posterior 

 angles of eye, and one behind the antennal ridge; labrum broadly 

 rounded; punctures moderately coarse but confused and crowded 

 in depressions ; without ground sculpture ; pubescence short but dis- 

 tinct. Pronotwm one-eighth longer than wide, widest near middle, 

 sides feebly arcuate in front, distinctly emarginate behind; with 

 coarse, irregular punctures, with an irregular smooth area at middle 

 and others at sides; intervals moderately convex; without ground 

 sculpture; pubescence short. Elytra three-fifths wider than pro- 

 notum, scarcely wider than long; humeral callus slightly prominent, 

 with another feeble prominence between humerus and suture; punc- 

 tures coarser than on pronotum, irregular in size and density; with- 

 out ground sculpture; pubescence short. Abdomen not margined; 

 with punctures very much finer than on elytra, rather sparse; no 

 ground sculpture except on apical segments; pubescence moderately 

 long. Tarsus with fourth segment bilobed. Male, sixth sternite 

 flattened apically and with denser pubescence, seventh same through- 

 out its length ; eighth with an even triangular emargination, slightly 

 wider than deep, apex scarcely rounded, outer angles gradually 

 rounded ; eighth tergite alone with ground sculpture. Female, apical 

 sternites not modified ; seventh and eighth tergites and sixth, seventh, 

 and eighth sternites with ground sculpture. Length, 3 to 3l^ mm. 



Type locality. — Cuba, Cayamas, 15 miles west-northwest of Cien- 

 fuegos, Santa Clara Province. 



Types. — Holotype, male and two paratypes, U.S.N.M. No. 52384, 

 collected by E. A. Schwarz on February 28 in 1902, 1903, or 1904. 



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

 Cuba: Cayamas (Schwarz, in U.S.N.M.). 



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



Remarks . — This species is distinct from all others in our region 

 by the large impunctate shining areas on the head. The male ab- 

 dominal characters are likewise distinctive. 



I have no record of its habits.
