30 MEMOIRS ON THE COLEOPTERA. 



than the second. Length 2.0 mm.; width 0.53 mm. Pennsylvania (Phila- 

 delphia). 



Readily distinguishable by the male sexual characters, strongly 

 asperate sculpture and well marked coloration. 



The following nine species can be recognized by individual pecu- 

 liarities of sculpture, coloration or male sexual characters; they all 

 belong to typical Atheta, but in no case is the sixth tergite clearly 

 crenulate at apex in the male, so far as known. 



Atheta strigosula n. sp. Large, rather stout, moderately convex, feebly 

 shining, the abdomen polished as usual but with extremely fine, feeble and 

 extremely close transverse strigilation ; punctures fine, close and asperate; 

 color brownish-piceous, the head and abdomen nearly black, the elytra and 

 legs pale brown; antennae pale basally; head rather small, the eyes at evi- 

 dently less than their own length from the base, the carinae fine, not quite 

 entire; antennae moderately long, only feebly incrassate, the second and third 

 joints long and equal, the tenth but slightly transverse; prothorax rather 

 transverse, parallel and rounded at the sides, not large, much wider than the 

 head but also very distinctly narrower than the elytra, with a small deep basal 

 impression; elytra large, rather transverse, much longer than the prothorax; 

 abdomen parallel, much narrower than the elytra, the fourth and fifth ter- 

 gites equal in length; sterna as usual, the mesosternum prolonged and finely 

 aciculate, the metasternum projecting and angulate; basal joint of the hind 

 tarsi scarcely more than half as long as the second. Length 3.5 mm.; width 

 0.8 mm. New York (Catskill Mts.). 



I have described this species from the female because of its very 

 distinct abdominal sculpture, distinguishing it from any other species 

 of true Atheta here made known; also because of its large size and 

 other striking characters. The male is unknown. 



Atheta remulsa n. sp. Moderately convex, subparallel, slightly shining, 

 minutely, asperulately punctate, loosely on the head and pronotum, closely 

 on the elytra; color dark piceous, the head darker, the abdomen black, the 

 elytra and legs pale; head moderate, with a small central fovea, the eyes 

 moderately prominent, at about their own length from the base, the carinae 

 fine, not quite entire; antennae rather short, gradually distinctly incrassate, 

 the second and third joints equal in length, cylindric and obconic respectively, 

 the outer joints rather strongly transverse; prothorax transverse, parallel, 

 rounded at the sides, much wider than the head and distinctly narrower than 

 the elytra, feebly and finely impressed along the median line; elytra distinctly 

 wider than long, much longer than the prothorax; abdomen parallel, distinctly 

 narrower than the elytra, the fourth and fifth tergites equal in length, the 

 sixth (cf ) with an acute and nearly flat tooth projecting posteriorly at each 

 side, the apex broadly sinuate medially between two feeble projections, 

 each of which is separated from the lateral teeth by a deep and narrow 

 sinus, the edges even; sterna as usual, the mesosternum not very acutely
