Casey — A Revision of the American Paederini. 157 
Sciocharis 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. Sciocharis is probably equally well 
represented throughout Central America and Mexico, so that 
it may be said to be oneof 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 than long, somewhat strongly obtrapezoidal with the 
sides straight, the angles very narrowly rounded and distinct, 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.; width0.75 mm. Texas (Browns- 
Ville), — Mr. Wickham......sceesseerccecccccerece nubipennis n. sp.

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.
