ClCINDELID^E AND CARABID/E 83 



distinctly shorter. Length 29.0-32.0 mm.; width 11.5-12.4 mm. 

 Indiana. Three examples from the Levette collection. 



punctulatus Hald. 



Body much less inflated and relatively less depressed, shining, deep black, 

 the side margins rather narrower, violaceous; head relatively 

 smaller, the mandibles smooth in the type, the terminal part of the 

 left slender, moderate in length, of the right broader and more 

 gradually acuminate; median lobe of the labrum broad, evenly 

 rounded, the lateral lobes obsolete and with the edge transverse; 

 impressions of the vertex strong; prothorax not quite one-half 

 wider than long, much narrower at base than at apex and rela- 

 tively narrower at base than in the preceding, the sides parallel 

 for a long distance from the distinct and right basal angles; grooves 

 and impressions nearly as in mono; elytra narrower and less rounded 

 at the sides than in the preceding, the series geminate only internally, 

 equally but similarly closely spaced externally, the punctures well 

 spaced in the series and rather large and strongly impressed, con- 

 spicuous, the humeral carina feebly prolonged in a slightly more 

 evident line at the upper limit of the flanks but without trace of a 

 more lateral ridge; series of granuliferous setigerous punctures of 

 the concave side margins unusually strong and close-set; hind tarsi 

 in the type only moderately slender and about as long as the tibiae, 

 the latter without brush of hair internally. Length 28.0 mm.; 

 width 10.7 mm. Missouri (St. Louis). A single example of unde- 

 termined sex, though probably male, was taken by the writer in the 

 suburbs sinuatus n. sp. 



15 Sides of the prothorax very moderately converging posteriorly, and, 

 toward the angles, becoming only very broadly and feebly sinuate, 

 the angles however sharply marked 16 



Sides of the prothorax strongly converging posteriorly, with a long strong 

 basal sinus, the sides becoming straight and parallel for a considerable 

 distance before the angles, which are right and sharply marked. . 17 



16 Form elongate, suboval, moderately convex, nearly similar in the 

 sexes, except that the female has the elytra slightly more elongate 

 and more parallel toward base, deep black, shining, the margins 

 bluish-violaceous and rather wide; head large, three-fourths as wide 

 as the prothorax, the mandibles well developed, finely strigose, 

 partially (cf) or almost wholly (9), the former having the slender 

 apical part a little more prolonged; labrum with a rather broad, 

 rounded or feebly bilobate median lobe; linear impressions deep; 

 prothorax barely one-half wider than long, the base much narrower 

 than the apex; marginal and basal grooves not quite attaining the 

 angles, the basal strong and even; single pair of subbasal impressions 

 distinct; elytra oval, with rounded sides (cf), oblong-oval (9), 

 smooth, only rarely exhibiting geminate series of very small and 

 feeble punctures; tarsi (c?) long, distinctly longer than the tibia?, 

 which are densely pubescent within apically, or ( 9 ) a little more 

 slender, much shorter and subequal in length to the tibia?, which have 

 fewer bristling hairs within apically. Length 26.0-28.5 mm.;
