American Caraboidea 207 



assigned to it, I do not think so radical a change as that indicated 

 can be allowed, and the species Badister micans, commonly so 

 called, must therefore be regarded as undescribed. 



The species of Badister seem to be numerous in North America, 

 though generally rare individually. Those at present in my col- 

 lection may be known as follows: 



Elytral striae deep, smooth, the intervals narrow and convex; species 

 very small in size 2 



Elytral striae less deep, the intervals feebly convex 4 



2 — Head smaller, not quite as wide as an elytron, the eyes smaller and 

 very prominent. Body narrower, convex and shining, black, with 

 pale legs, the elytra piceous, testaceous in nearly basal half, except 

 near the suture, which is narrowly testaceous throughout; head 

 three-fourths as wide as the prothorax, convex, smooth, the anterior 

 impressions minute and very feeble; last palpal joint much longer 

 than the third; antennae pale, two-thirds as long as the body, the 

 medial joints between two and three times as long as wide; pro- 

 thorax convex, a fourth wider than long, widest at apical third, 

 where the sides are rather strongly rounded, oblique and straight 

 basally, the angles obtuse and slightly blunt; anterior impression 

 near the sinuato-truncate apex and distinct, the posterior obsolete, 

 the stria rather coarse and deep, not quite entire; foveae coarse, 

 deep, elongate; sides very finely reflexed, abruptly a little more 

 so at base, which is somewhat wider than the apex; elytra three- 

 fifths longer than wide, not quite one-half wider than the prothorax, 

 elongate-oval, convex, the striae deep, relatively coarse, the intervals 

 flatter behind; dorsal punctures two, small and feeble, adhering 

 externally to the second stria; apex evenly and obtusely rounded. 

 Length (cf) 3.5 mm.; width 1.25 mm. Illinois angustus n. sp. 



Head larger, slightly wider than an elytron, the eyes relatively larger 

 but not quite so prominent; coloration almost similar, the suture 

 not definitely paler and the antero-external rufous areas even more 

 nubilous; antennae clearer testaceous basally 3 



3 — Antennae shorter, rather more compressed, three-fifths as long as the 

 body, the medial joints barely twice as long as wide; body narrower, 

 polished, strongly convex; head very smooth, convex, becoming 

 deplanate at the sides apically; fourth palpal joint subinflated and 

 wider and much longer than the third, gradually acutely pointed; 

 prothorax nearly a third wider than long, in form and structure 

 nearly as in the preceding, but with the posterior transverse im- 

 pression visible, the foveae less elongate, narrower and deeper, the 

 sides basally more reflexed ; base much narrower, not as wide as the 

 sinuato-truncate apex; elytra four-sevenths longer than wide, 

 only a third wider than the prothorax, nearly as in angustus but 

 still more obtusely rounded at apex. Length (9) 3-7 mm.; width 

 1.3 mm. New York (Long Island),- — Shoemaker.. . .gilvipes n. sp. 



Antennae in both sexes much longer and relatively more slender, nearly 

 three-fourths as long as the body, the medial joints nearly three
