American' Caraboidea 249 



deplaniture not so abrupt and merging gradually into the reflexed 

 margins; elytra between a fourth and third longer than wide, 

 moderately inflated posteriorly, two and one-half times as wide as 

 the prothorax; striae finer, more regular, less impressed, the intervals 

 just visibly convex, less so that in the preceding; tarsi very slender, 

 the fourth joint similarly narrowly bilobed. Length 2.45-3.0 mm.; 

 width 1.1-1.35 mm. Rhode Island and Pennsylvania (near Phila- 

 delphia) pumila Dej. 



22 — Elytra quadrate, barely perceptibly longer than wide. Body 

 ventricose, moderately convex, deep black, the elytra polished, with 

 very feeble greenish lustre, the anterior parts feebly alutaceous 

 and without trace of metallic lustre; under surface shining, black, 

 the legs very pale brownish-flavate, the tarsi darker and very slender; 

 head rhomboidal, with rather prominent but very moderate eyes, 

 the surface convex and nearly smooth; antenna? somewhat slender, 

 more than half as long as the body, the pale third joint notably 

 elongate, relatively longer than in pumila; prothorax small, in 

 almost every respect as in pumila, the transverse basal sulcus angu- 

 late at the middle, the impressed stria extending from the angle to 

 the obsolescent transverse anterior impression; elytra scarcely at 

 all inflated posteriorly, with the sides broadly arcuate, much more 

 than twice as wide as the prothorax; striae moderately fine, some- 

 what irregular, the intervals virtually flat. Length 2.8 mm.; 

 width 1.25 mm. North Carolina (Southern Pines), — Manee. 



quadrata n. sp. 



Elytra elongate, a fourth to third longer than wide 23 



23 — Antennae longer, slender, scarcely at all compressed, more than half 

 as long as the body, the latter shining, black, faintly subaeneous, 

 the anterior parts not distinctly alutaceous; under surface black, 

 the legs piceous; head rhomboidal, equal in width to the prothorax, 

 the eyes prominent but rather small, onl>' slightly longer than the 

 gradually converging tempora behind them; third antennal joint 

 piceo- testaceous; front nearly smooth; anterior superciliary punc- 

 ture notably large; prothorax almost as in the preceding species, 

 but with the anterior transverse impression more distinct, angulate 

 at the middle, the median stria — extending thence to the angulation 

 of the basal sulcus — rather deeply impressed; elytra a third longer 

 than wide, gradually arcuately subinflated posteriorly, much more 

 than twice as wide as the prothorax, the color faintly picescent; 

 striae extremely fine and feeble, in part almost obliterated, the 

 intervals flat; dorsal punctures small. Length 3.0 mm.; width 

 1.25 mm. Northern Illinois illini n. sp. 



Antennae shorter, scarcely half as long as the body and very stout, only 

 feebly compressed; body black, the anterior parts feebly alutaceous, 

 the elytra shining and very feebly subaeneous; under surface black, 

 with faintly picescent epipleura; legs dark piceous; head rhom- 

 boidal, with rather prominent though very moderate eyes, which 

 are scarcely longer than the tempora, not quite as wide as the pro- 

 thorax; surface strongly micro-reticulate, the anterior superciliary 

 puncture rather large; third antennal joint pale flavo-testaceous;
