ClCINDELID/E AND CARABID/E 145 



deep, broad and straight, extending posteriorly to a line through the 

 middle of the eyes; prothorax a third wider than the head, fully 

 two-fifths wider than long, the sides rounded, moderately converging 

 posteriorly, becoming gradually very broadly and feebly sinuate, 

 the hind angles right and rather sharply marked; base fully three- 

 fourths the maximum width; surface rather depressed, the transverse 

 impressions as in the preceding, the stria deep; confluent impressions 

 forming a deep concavity, which is scarcely at all punctured, the 

 inner and outer impressions more or less lineiform, separated by a 

 feeble convexity at the bottom of the concavity, the inner not 

 extending anteriorly more than slightly; lateral margin deeply but 

 not widely concave except basally, where it becomes broad as usual; 

 elytra short, oblong, less than one-half longer than wide, fully 

 two-fifths wider than the prothorax, the striae finely, very indistinctly 

 punctulate, deeply impressed basally, where the intervals are very 

 convex; seventh stria subobsolete throughout the length; male 

 with the subapical denticle of the middle tibiae very slender, small 

 in size, the apical process obsolete; last ventral evenly rounded and 

 with very fine marginal bead, having a small broad and scarcely 

 visible median sinuation. Length (cT 9 ) 15.0-17.7 mm.; width 

 5.8-6.6 mm. Indiana and Illinois. Cleveland, Ohio LeConte. 



scrutator Lee. 



Elytral striae very fine, with flat intervals posteriorly, the body smaller 

 in size and of narrower and less depressed form 4 



4 Form moderately elongate and convex, polished and deep black 

 throughout in both sexes, the tarsi piceous; antennae dark brown, 

 blackish basally, the palpi rufo-piceous; head rather large, with very 

 prominent eyes, the impressions finer and shallower than in scrutator, 

 arcuate and not extending to the middle of the eyes; labrum sinuato- 

 truncate; prothorax formed nearly as in the preceding but with the 

 sides posteriorly not sinuate, being straight or very feebly arcuate 

 nearly to the angles, where there is a scarcely perceptible sinuation, 

 the angles very obtuse but denticularly prominent, the base three- 

 fourths the maximum width; surface very feebly convex, the median 

 stria and anterior impression as in the preceding, the marginal 

 gutter and reflexed edge conspicuous, the basal impressions linear, 

 not confluent, the concavity including them shallow, impunctate; 

 elytra oblong, three-fifths longer than wide, only very slightly and 

 not evidently wider than the prothorax (of), a little wider ( 9 ), the 

 sides feebly arcuate; apex strongly rounded; striae moderate, finely 

 and obscurely punctulate, deeply impressed basally at the sides, 

 to near the middle suturally, elsewhere very fine and unimpressed, 

 the seventh almost completely obsolete, the scutellar long and deep; 

 intervals convex basally; male with the subapical spine of the middle 

 tibiae acute and distinct, the apical process feeble but evident, 

 sharply angulate; last ventral more narrowly rounded than in the 

 preceding, with a broader flattened marginal beading and a nar- 

 rower, deeper and very distinct median sinus. Length (cf 9 ) 

 15.0-15.7 mm.; width 5.2-5.75 mm. Illinois illini n. sp.
