STAPHYLINID.E. 45 



shining, testaceous, the pronotum barely at all darker, the pale elytra 

 postero-externally and toward the suture infumate, the head and abdomen 

 black, the segmental apices feebly pale, the legs pale; punctures fine and 

 dense, asperulate on the elytra, the abdominal asperities isolated and 

 strong, becoming larger and sparser posteriorly; pubescence close, coarser 

 and less close on the abdomen; head parallel, wider than long, fully 

 three-fifths as wide as the prothorax, the eyes moderate, slightly convex 

 and prominent; antennae short, dark, paler basally, rather rapidly 

 incrassate and stout apically, the second joint distinctly longer than the 

 third, fourth as long as wide, the tenth rather strongly transverse, 

 eleventh fully as long as the two preceding, obtusely pointed at tip; 

 prothorax as in the preceding but relatively larger, unimpressed; elytra 

 evidently though not greatly shorter than wide, subparallel, at base 

 barely as wide as the prothorax, the suture about a fourth longer, the 

 apical sinuses rather shallow; abdomen nearly as wide as the elytra, 

 parallel throughout, the margins rather thick, very thin on the moder- 

 ately long though transverse fifth tergite, giving the appearance of 

 slight posterior narrowing; basal joint of the hind tarsi as long as the 

 next two combined. Length 1.9-2. 4 mm.; width 0.48-0.65 mm. New 

 Jersey (Atlantic City). 



Much stouter than the preceding and differing in numerous fea- 

 tures; fully as stout as agitata, and with much more developed pro- 

 thorax. 



The remaining thirteen species here described, having less asperate 

 though not necessarily denser abdominal sculpture, are divisible into 

 a few rather feebly differentiated sections, which possibly may be 

 recognized. The two following species are rather narrow, almost 

 perfectly parallel and of very dark coloration, the elytra less de- 

 veloped than in most of those of Group IV: 



Oxypoda morula n. sp. Parallel, only moderately convex, dull, the 

 abdomen more shining and with rather coarse, asperulately imbricate 

 sculpture, the anterior parts throughout very densely punctate, the 

 elytra more coarsely and roughly, the vestiture short and dense, sparser 

 and longer on the abdomen; color piceous-black, the head and abdomen 

 deep black, the legs dark brown; head triangular, widest at base, wider 

 than long, nearly two-thirds as wide as the prothorax, the eyes at one- 

 half more than their own length from the base, the infra-lateral carinae 

 wholly obsolete; antennae short, rather slender, only feebly incrassate, 

 dark piceous throughout, the basal joint somewhat longer than the 

 second, the latter longer than the third, fourth not quite as long as wide, 

 the outer joints strongly obtrapezoidal and rather transverse, the last 

 obtuse at tip and not quite as long as the two preceding; prothorax 

 nearly one-half wider than long, the sides evenly arcuate, converging 

 but little more apically than basally, the base rounded, with the angles 

 obtuse though distinct, the surface very finely and feebly impressed along
