half wider than the prothorax; striae coarse, rather deeply impressed, 

 fine and obsolescent only very near the apex; punctures coarse, 

 deep, moderately close, obsolescent near apical fourth; seventh 

 stria represented by a distinct series of minute punctures; foveae 

 strong, near basal and apical third. Length (9) 5.4 mm.; width 

 2.3 mm. British Columbia (Victoria), YVickham. 



insopitans n. sp. 



Prothorax strongly narrowed behind, the base much narrower than the 

 apex; elytra feebly and very nubilously rufescent apically as a rule; 

 seventh stria subobsolete 43 



43 Sides of the prothorax abruptly parallel in basal fifth or sixth. Body 

 short and strongly convex, highly polished throughout, bluish-black; 

 head well developed, three-fourths as wide as the prothorax and as 

 wide as an elytron; antennae long, slender, fuscous, gradually tes- 

 taceous basally; prothorax relatively large, convex, a third wider 

 than long; base not three-fourths the maximum width, the sides 

 evenly and strongly rounded to the abrupt short posterior sinus; 

 surface smooth, the impressions subobsolete, the stria fine, abbre- 

 viated in front; foveae small, smooth, short, linear and very deep, 

 the carina extremely short and fine; elytra scarcely one-half longer 

 than wide, two-fifths wider than the prothorax and less than three 

 times as long, the sides broadly arcuate, rapidly rounding at the 

 humeri, ogival in posterior two-fifths, the striae coarse and deep, 

 becoming wholly obsolete in apical fifth or sixth; punctures notably 

 coarse and deep, separated by barely their diameters, rapidly obso- 

 lescent at the ends of the striae; foveae moderate, near basal and 

 apical third. Length (cf) 5.3 mm.; width 1.9 mm. A single 

 Levette specimen, probably from Indiana histricum n. sp. 



Sides of the prothorax becoming parallel only very near the basal angles; 

 elytra more elongate 44 



44 Form elongate, convex, highly polished throughout, greenish-black 

 above; head moderate, three-fourths as wide as the prothorax, dis- 

 tinctly narrower than an elytron, the sulci deep; antennae long, as 

 in the preceding species, fuscous, gradually testaceous basally; eyes 

 not so strongly convex as in some others of this subsection; pro- 

 thorax relatively much smaller than in the preceding or succeeding 

 species, a third wider than long, convex, the sides strongly rounded, 

 becoming rather abruptly sinuate near the base; surface smooth, 

 the impressions very feeble, the stria very fine, biabbreviated ; foveae 

 moderate, linear, smooth, very deep, close to the moderately strong 

 distinct carina; elytra three-fifths longer than wide, rather more 

 than one-half wider than the prothorax, gradually ogival behind, 

 the sides but feebly arcuate, the humeri rather rapidly rounded; 

 striae moderate, somewhat feebly impressed, obsolete near apical 

 sixth or seventh; punctures only moderately coarse and widely sep- 

 arated by fully twice their diameters in most cases; foveae moder- 

 ate, near basal and apical third. Length (cf 9 ) 5.3-6.0 mm.; width 

 1.9-2.15 mm. Texas (Austin) and Iowa (Keokuk). A very pale 

 brownish-yellow specimen from New Mexico and another similar 

 from Missouri, do not seem to differ specifically, though there are
