214 BULLETIN 18 2, UNITED STATES NATIONAL MUSEUM 



Description. — Similar to alumnus Sharp but differing as follows: 

 Black, subopaque. Head as wide as elytra; more strongly and 

 densely punctate; without metallic lustre; antennae not clavate. 

 Pronotum shorter, scarcely longer than wide; more coarsely and 

 densely punchite. Elytra much shorter, together somewhat wider 

 than long; more coarsely punctate and much more densely and con- 

 fusedly channeled. Ahdomen cylindrical; somewhat more densely 

 punctate. Male^ seventh sternite somewhat flattened ; eighth sternite 

 with a broad triangular emargination, not large and extending not 

 far in the surface of the sternite. Length, 2 mm. (From Bern- 

 hauer.) 



Type locality. — Cuba, Habana. 



Types. — One male, presumably in the collection of Max Bernhauer. 



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

 Cuba: (Leng and Mutchler, 1914), Habana (Bernhauer, 1910). 



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



Remarks. — This species was rather briefly described without men- 

 tion of subgeneric characters. These have been assumed from its 

 position in the catalog (Bernhauer and Schubert, 1910, p. 172). If 

 the species is really subopaque, it is quite distinct from all those 

 from the West Indies before me by that character. 



I find no record of its habits. 



6. STENUS JAMAICENSIS, new species 



Description. — Black, pronotum and elytra generally violet-black. 

 Head not distinctly biimpressed between the eyes; not abruptly ele- 

 vated at edge of eyes ; labrum broadly rounded ; with very coarse and 

 deep punctures separated generally by less than half their diameter, 

 intervals flat; without distinct impressed areas; without gi'ound 

 sculpture. Pronotum one-third longer than wide, widest just be- 

 hind middle, not greatly narrowed cither way ; with very coarse and 

 deep punctures, separated by less than half their diameter by evenly 

 convex intervals, without ground sculpture. Elytra about one-half 

 wnder than pronotum, one-fifteenth longer than wide; with humeral 

 callus scarcely at all elevated and without impressions; with punc- 

 tures as on pronotum but generally separated by their diameter or 

 more; without ground sculpture or pubescence. Ahdomen not mar- 

 gined; with basal segments punctured as elytra but with punctures 

 less coarse, becoming less impressed apically ; eighth tergite only with 

 distinct scaly ground sculpture; with sparse pubescence only at tip; 

 eighth sternite bordered with a row of minute spinules; basal part 

 of ninth tergite broadly emarginate and bordered with fine spinules 

 of much greater length than on the eighth sternite. Tarsus with 

 fourth segment bilobed. Length, 41/2 to 5^2 nim.
