66 MEMOIRS ox THE COLEOPTERA. 



much as twice as long as wide, the outer joints moderately transverse, 

 the last gradually pointed, equal in length to the two preceding ; prothorax 

 rather transverse, the sides parallel and evenly, notably rounded, impressed 

 along the middle only very feebly and toward base, very distinctly wider than 

 the head and narrower than the elytra, the latter transverse, truncate, paral- 

 lel, the suture about a fourth longer than the prothorax; abdomen distinctly 

 narrower than the elytra, slightly narrowing apically, the tergites subequal, 

 the sixth (c?) comparatively narrow, truncate transversely and even, with a 

 small ear-like process at each side, the punctures strong and asperate, 

 moderately numerous; sterna as in the preceding, except that there is a 

 slightly longer interval between the metasternum and the broadly obtuse 

 mesosternal apex. Length 1.8 mm.; width 0.48 mm. Pennsylvania (near 

 Philadelphia). 



Evidently allied subgenerically to the preceding, in spite of the 

 different type of male sexual modification. 



Atheta (Philhygra) frugalis n. sp. A little smaller and less stout, similar in 

 lustre and sculpture but with the fine and rather close punctures less asperate, 

 somewhat shining; color piceous, the head and abdomen, except apically 

 and toward base, black, the elytra piceo-fiavate, the legs flavate; head wider 

 than long, the eyes large, very convex and prominent, much longer and more 

 prominent than the tempora, the carinae subentire; antennae rather short, 

 gradually rather strongly incrassate, the basal joint not quite as long as the 

 next two, which are subequal and each nearly twice as long as wide, the outer 

 joints transverse, the last gradually pointed and as long as the two preceding; 

 prothorax distinctly wider than the head and narrower than the elytra, moder- 

 ately transverse, parallel, the sides subevenly and evidently arcuate, having a 

 small rounded impression at base; elytra moderately transverse, about one-half 

 longer than the prothorax; abdomen distinctly narrower than the elytra, 

 parallel, the fifth tergite slightly trapezoidal, as long as the fourth, the sixth 

 (cf) narrowly and feebly sinuate at apex, the sinuate part separated at each 

 side from a small slender process by a very small, narrow and rather 

 deep sinus; metasternal projection unusually short, its apex subparabolic. 

 Length 1.75 mm.; width 0.45 mm. New York (Catskill Mts.). 



Distinguishable from the preceding by its narrower form, dif- 

 ferent coloration and by the male sexual characters. 



Atheta (Philhygra) leviceps n. sp. Slender, moderately convex, not paral- 

 lel, rather dull in lustre, the fine punctures close-set and strongly asperulate 

 throughout; color dark piceous-brown, the elytra paler, brownish-flavate, 

 the legs rather pale piceous; pubescence very short and inconspicuous; head 

 small, orbicular, the eyes large, convex, at scarcely more than half their length 

 from the base, the tempora rapidly converging behind them, the carinae en- 

 tire; antennae short, moderately incrassate, the second joint but little longer 

 than the third, each much shorter than the first, the outer joints evidently 

 transverse, the last gradually pointed, longer than the tw T o preceding; pro- 

 thorax moderately transverse, parallel, with evenly and moderately rounded 

 sides, much wider than the head and distinctly narrower than the elytra,
