Casey — A Revision of the American Paederini. 157 



Sciocliaris Arrib. 



A part of the large collection of Staphylinidae brought 

 back from Brazil by Mr. H. H. Smith, placed in my hands 

 for examination some years ago, revealed a most astonishing 

 variety in this genus and I remember mounting about twenty 

 species; to state therefore that there are more than a hundred 

 species within the limits of Brazil alone, ought to be a very 

 conservative estimate. Sciocliaris is probably equally well 

 represented throughout Central America and Mexico, so that 

 it may be said to be one of the largest — possibly the largest — 

 genus of American Paederini. In the United States of 

 America, it is represented, as far as known to me at present, 

 by the three following species, the first of which belongs 

 more properly to the fauna of Mexico : — 



Second antennal joint much thicker but not longer than the third; punctures 

 much finer, dense, the lustre dull; body rather stout, subdepressed, 

 parallel, pale flavo-testaceous throughout, the head but little darker, 

 the elytra with a large feeble piceous cloud, not extending to the sides, 

 base or apex ; head well developed, wider than long, parallel at the sides, 

 the eyes at but little more than their own length from the base, the 

 angles rather narrowly rounded; prothorax distinctly narrower than the 

 head and wider thau long, somewhat strongly obtrapezoidal with the 

 sides straight, the angles very narrowly rounded and di-jtinct, the basal 

 broadly rounded; elytra quadrate, parallel, a fourth wider and nearly 

 one-half longer than the prothorax and slightly wider than the head. 

 Male not known. Length 3.0 mm.; width 0.75 mm. Texas (Browns- 

 ville) , — Mr. Wickham linbipeiiiiis n. sp . 



Second antennal joint much longer, as well as thicker, than the third; 

 punctures of the head and pronotum stronger 2 



2 — Color pale brown throughout, the head slightly darker, piceous; lustre 

 dull; body parallel, moderately convex, the head well developed, as 

 wide as the elytra, parallel and feebly arcuate at the sides, the eyes at 

 nearly twice their own length from the base, the angles moderately 

 rounded; prothorax distinctly obtrapezoidal, well developed, nearly as 

 wide as the head, wider than long, the sides nearly straight, all the 

 angles broadly rounded; elytra quadrate, parallel, about a sixth wider 

 and a third longer than the prothorax. Length 3.0 mm.; width 0.65 

 mm. North Carolina (Asheville) and District of Columbia. 



carolinensis n. sp. 



Color blackish, the abdomen piceous, the legs dark brown and the antennae 

 still paler; lustre alutaceous, the punctures dense; body subparallel,
