STAPHYLINID^E 217 



Gyronycha lepida n. sp. Moderately slender, only feebly convex, 

 shining, piceous-brown, the head blackish, the elytra paler and more 

 flavate, the abdomen testaceous; punctures very fine and close-set, 

 sparse on the abdomen, pubescence moderately long; head quadrate, 

 parallel, as long as wide, evidently narrower than the prothorax, the 

 eyes slightly prominent, at much more than their own length from the 

 base, the tempora slightly less prominent, straight and parallel, broadly 

 rounding at base; antennae long, gradually and evidently incrassate, 

 throughout nearly as in fusciceps; prothorax not quite so long as wide, 

 subparallel, just visibly wider near apical third than at base, the sides 

 feebly arcuate, less so basally, the basal angles obtuse and somewhat 

 blunt, the surface with a feeble transverse ante-scutellar impression; 

 elytra rather longer than wide, parallel, with straight sides, fully a third 

 wider and three-fifths longer than the prothorax; abdomen long, parallel, 

 much narrower than the elytra, the fifth tergite fully one-half longer 

 than the fourth. Length (9 ) 2.5 mm.; width 0.6 mm. North Carolina 

 (Asheville). 



This species was confounded with fusciceps in my previous 

 revision; it is closely allied to the latter, resembling it in general 

 size and form, but differs in many minor features; the head, for 

 example, is not at all swollen behind the eyes as it is in that species, 

 the eyes are evidently not as large and the antennae less strongly 

 incrassate distally; the prothorax is .slightly broader and, finally, 

 the coloration is somewhat darker, the pubescence longer and the 

 punctures of the abdomen more numerous; the types of both 

 species are females and I have before me three examples of each. 



Gyronycha longicornis n. sp. Similar in coloration, lustre and sculp- 

 ture to the preceding and fusciceps; head smaller, not quite as long as 

 wide and four-fifths as wide as the prothorax, the eyes large, at but little 

 more than their own length from the base, the tempora parallel though 

 slightly swollen and a little more prominent than the eyes; front feebly 

 canaliculate on the median line before the middle and thence, at each 

 side of the middle, toward the antennae, the latter notably long, extending 

 to the tips of the elytra, gradually incrassate, infumate, gradually paler 

 basally, the third joint as long as the first and distinctly longer than the 

 second, fourth more than a fourth longer than wide, fourth to tenth all 

 longer than wide, obtrapezoidal though decreasingly so, the tenth a fourth 

 longer than wide, the last elongate-oval, as long as the two preceding; 

 prothorax slightly wider than long, widest before apical third, where 

 the sides are somewhat prominently rounded, thence slightly converging 

 and straight to the very obtuse basal angles, the base and apex both 

 rounded, the surface with the transverse ante-scutellar impression almost 

 obsolete; elytra not quite as long as wide, with feebly diverging straight 

 sides, about a fourth wider and less than one-half longer than the pro- 

 thorax; abdomen distinctly narrower than the elytra, parallel, very feebly
