438 CASEY 



Body more slender anteriorly, the hind body relatively more strongly in- 

 flated, as frequently the case in the female, rufo-piceous in color, 

 shining throughout and glabrous ; head finely, sparsely punc- 

 tured, with about two juxta-carinal folds ; prothorax formed nearly 

 as in gracilicor?iis but arcuately narrowed behind only in about 

 basal half, the apical angles not at all thickened or prominent, the 

 punctures not very small and moderately sparse, impressed, be- 

 coming unusually coarse and separated by scarcely more than 

 their own widths laterally; elytra more elongate-oval, more than 

 one-half longer than wide, the scarcely at all impressed series 

 composed of moderately coarse, deep punctures which are rather 

 more close-set than usual, the interstitial punctures extremely 

 minute and subobsolete even basally ; basal segment of the ab- 

 domen even more coarsely and plentifully punctate medially than 

 usual. Length 7.5 mm.; width 3.2 mm. (9). Arizona.

14 — Form elongate, convex, shining, the elytra somewhat alutaceous, 

 black, the under surface, legs, head and prothorax more or less 

 rufo-piceous ; minute hairs frequently distinct ; head rather coarsely 

 and longitudinally, subconfluently punctate, forming rugffi, those 

 near the strong orbital carinte not more pronounced than the 

 others ; antennae rather long and slender, the tenth joint longer 

 than wide; prothorax a little wider than the head, more distinctly 

 in the female, almost one-half wider than long, moderately and 

 arcuately narrowed behind in rather more than basal half, the 

 apical angles not thickened or prominent, the punctures rather 

 coarse, deep, well separated medially but still coarser, elongate 

 and separated by their own widths but tending to longitudinal 

 coalescence laterally ; elytra very elongate-oval, much less inflated 

 than usual, three-fifths longer than wide, the very feebly impressed 

 series composed of moderately coarse, unusually close-set punc- 

 tures and distinct to within a short distance of the apex, the inner 

 series curving outwardly toward base, where there is sometimes a 

 short post-scutellar series; interstitial punctures small and sparse, 

 confused, sometimes very distinct; abdomen, contrary to the 

 general rule, evenly and rather sparsely but strongly punctured 

 throughout, the pubescent fovea of the first segment (cj*) not im- 

 pressed and moderate in size. Length 6.4-7.3 mm. ; width 2.7- 

 2.85 mm. (c? and $). California (Tulare Co.)...rugiceps Lee. 



Form very stout, large in size, deep black, shining and glabrous 

 throughout, the legs rufo-piceous and the elytra feebly alutaceous 

 posteriorly; head slightly narrower than the prothorax, the an- 

 terior tumidity large, strong and punctured as usual, the basal 

 parts convex, very finely, sparsely punctured and smooth, with 

 about two tolds near the carinje ; antennas rather long and slender, 

 the tenth joint slightly elongate ; prothorax large, not quite one- 

 half wider than long, inflated at the middle, thence rather strongly 

 narrowed, with the sides becoming sinuate to the base, the an-
