California (locality not known). 



This species is distinct, among those of the present group, in 

 having the sides of the prothorax sinuate deeply behind and par- 

 allel for a considerable distance before the base as in ventricosus 

 and many other forms not closely related. It is allied to sculpti- 

 pennis, but the single male before me differs from the correspond- 

 ing sex of that species in its more elongate and less ventricose 

 form and very much larger prothorax ; the sexual characters 

 are similar,

Rather elongate and moderately ventricose, polished, the pro- 

 notum feebly alutaceous ; body deep black throughout, with very 

 feeble bluish lustre, the eh^tral margins with blue or violaceous 

 metallic reflection. Head stout, onlj' moderately elongate, the 

 vertex feebly, transversely wrinkled near the middle; gense feebly 

 developed and having a minute cleft-like incisure ; supra-orbital 

 ridges fine posteriorly, strong at the antennte, the latter not |- as 

 long as the bodj^, slender, only slightly thicker basally, the first 

 joint thicker, not quite as long as the next two but much longer 

 than the third. Prothorax relatively large, slightly wider than 

 long, strongly dilated and rounded anteriorl}^, strongly rounded 

 just before the middle, the sides thence strongly oblique and 

 straight to the subbasal sinuation, thence almost parallel and 

 straight to the base, the angles very slightly more than right ; 

 base not quite ^ the maximum width and subequal in width to the 

 head ; disk feebly convex, the impressions rather distinct ; mar- 

 gins moderately deep and almost vertically reflexed. Elytra al- 

 most evenly elliptical, -f longer than wide, 2| times as long as the 

 prothorax and not more than twice as wide, rather full and 

 strongly rounded at the humeri ; reflexed margins moderate and 

 having coarser, widely separated punctures ; disk moderately 

 convex, with rather fine but broadly and deeply impressed striae 

 bearing moderate and somewhat distant punctures, the intervals 

 relatively wide and only moderately convex, frequently inter- 

 rupted near the sides and apex but only occasionally and partially 

 toward the middle. Length 15.5-17.0 mm.; width 6.4-Y.3 mm, 



California (near Monterey), The pubescent pad of the first 

 anterior tarsal joint of the male above described, occupies much 

 less than apical half. There do not seem to be any papillae on the
