STAPHYLINID^E. 2 1 



a few sparse feeble elevations, broadly flattened medially, the flat- 

 tened part limited at each side by fine feeble parallel ridges, which 

 are nearly straight but curve apically partially around the contour 

 of the apical lobes; the apex of this flattened surface is strongly 

 bilobed, the lobes strongly, evenly rounded and separated by a 

 narrow deep rounded sinus. 



Atheta sibylla n. sp. Rather stout, moderately convex, black, the elytra 

 blackish-piceous, the legs pale, the antennae blackish throughout; surface 

 moderately shining, densely micro-reticulate, the abdomen more coarsely 

 though much more feebly so and strongly shining; vestiture short, not very 

 dense, the punctulation very fine, rather loose, closer on the elytra which are 

 less shining, very sparse on the abdomen; head with a central impression, 

 feebly punctulate, rather shining, the eyes at more than their own length from 

 the base, the rounded tempora parallel ; antennas rather long and thick, though 

 but feebly incrassate, the outer joints only slightly transverse, the second 

 longer than the third; carinae very fine and feeble, incomplete; prothorax 

 slightly wider than the head and a little narrower than the elytra, widest 

 before the middle, with rounded sides which become straighter basally, 

 the basal angles obtuse and rounded ; surface sparsely punctulate, flattened 

 along the middle; elytra wider than long, much longer than the prothorax; 

 abdomen distinctly narrower than the elytra, parallel, the sixth tergite (cf) 

 broadly, feebly sinuato-truncate, feebly crenulate on the edge except for a 

 moderately wide space at the middle; mesosternal process extending slightly 

 beyond the middle of the coxae, very finely aciculate at tip and distant from 

 the broadly and feebly parabolic metasternum, the intervening space deeply 

 sunken, the coxae contiguous; first four joints of the hind tarsi equal. 

 Length 2.6 mm.; width 0.75 mm. Virginia (Fort Monroe). 



To be readily known by the sternal structure, feeble carinae and 

 thick subfiliform antennas. 



Atheta weedi n. sp. Stout, rather convex, shining, black, the elytra and 

 legs pale brownish-flavate; antennae infuscate; head and pronotum sparsely 

 and not distinctly punctulate, the former not impressed, the eyes unusually 

 large, prominent, setose, distant from the base by a little less than their own, 

 length; prothorax transverse, relatively rather small, slightly wider than 

 the head but much narrower than the elytra, slightly widest just before 

 the middle, the sides rounded; basal angles obtuse and blunt; surface 

 broadly, feebly flattened medially, becoming gradually slightly impressed 

 basally; elytra large, wider than long, very much longer than the prothorax, 

 very finely, not densely and inconspicuously punctate; abdomen parallel, 

 with slightly arcuate sides, at the middle nearly as wide as the elytra, 

 minutely, sparsely punctate, the fourth and fifth tergites equal, the sixth 

 ( cf) with a projecting slender spur having its inner face concave at each 

 side of the broad apex, the edge between very broadly, evenly arcuate and 

 evenly tuberculato-crenulate; mesosternal process extending to the middle 

 of the coxae, unusually broad, nearly as in Stethusa, with its apex rounded 

 and separated from the large angulate metasternal projection by twice its
