COLEOPTERA OF SOUTHWESTERN PENNSYLVANIA. 347 



a slight appearance of a dorsal line. Elytra as wide as thorax, not longer, suture 

 not inipressed, punctuation same as tliat of thorax, but coarser; sides and a basal 

 triangle blackish, a triangle on each elytron pointing at humerus rufous as seen 

 in certain Aleochara : base arcuately emarginate to admit the thorax. Abdomen 

 as wide as elytra, sides parallel, deeply margined, iirst three segments concave, 

 black shining with a few setigerous punctures; underside shining black, ventral 

 segments punctate, but not very finely ; middle coxse widely separated, mesos- 

 ternum wide and divided into three equal parts by two oblique lines deeply im- 

 pressed anteriorly, but evanescent posteriorly (sub-trilobed), separated from the 

 metasternum by an accessory piece. 



Characterized from four examples without apparent sexual dis- 

 tincti(jn. Occui's not infrequently near St. Vincent, where it is taken 

 always with ants (^Fonnlca stibserieea Say) by Rev. Jerome Schmitt, 

 who kindly permits its description, and whose name it bears in com- 

 memoration of his zeal in micro-entomology. 



Hoinalillin (laviduin. — Rufo-testaceous throughout, shining, head 

 smooth, bipunctate between the antennse, which are gradually incrassate from the 

 second joint, and with the sixth and outer ones transverse. Thorax quadrate, 

 the sides slightly narrowed from middle to apex, hind angles rectangular, disc 

 with two longitudinal impressions not reaching apex, separated by a fine groove 

 reaching apex, where it is slightly dilated giving the appearance of a small im- 

 pression at apex more or less visible, sides impressed at middle. Elytra a little 

 wider than thorax, slightly wider from base, outer angles strongly obtuse, finely 

 closely punctured in approximate rows producing a longitudinal substriolate 

 appearance. Abdomen parallel, and of the same width as the elytra, alutaceous. 



Several examples occurred near St. Vincent. 



Atoniaria liuiueralis. — Elongate, depressed, plumbeous-brown, legs 

 paler, humerus and obsolete spot near elytral apex ferruginous. Length .09 inch. 

 Head smooth, vertex with a deep puncture. Antennae approximate, eighth joint 

 smaller than the ninth forming the base of the club. Tliorax quadrate, convex 

 transvei-sely and longitudinally, finely puuctulate and pubescent, margined at 

 base. Elytra slightly widened behind, a little wider at base than thorax and 

 three times longer, depressed, circularly impressed behind the scutellum, coarsely 

 closely punctate, pubescence fine, short, cinereous. 



Two examples taken in the ev^ening about a wood pile ; resembles 



but little ochracea or ephippiata ; the elytra are of a similar form 



to those of Xy/ophiliis tubercnlifer, but with coarser punctures. 



L>«>pi(loi»]iortis setiger. — Piceous, antennae and feet ferruginous, surface 

 with small round scales, elytra with rows of setae. Length .12-. 14 inch. Head 

 densely scaly, beak dilated towards tip, a little flattened above, densely scaly. 

 Antennae inserted near the tip, scape nearly as long as the outer part, extending 

 behind the eye, which is round and very small. Thorax a little wider than long, 

 convex, slightly narrowed anteriorly, not constricted at apex, except at sides, 

 densely rather coarsely punctured, each puncture with a small round scale very 

 fugitive, trivittate with fugitive whitish scales, surface piceous; scutellum not
