without a definite locality, but he selected the latter specimen as the 

 type. Chamberlin (1926) gives the type locality as Hot Springs, 

 and he also records a specimen in the United States National 

 Museum collection from Oracle, Ariz., but this specimen is parapiuta

Male. — Broadly elongate, strongly flattened above, moderately shining, pur- 

 plish brown, with a vague cupreous reflection in different lights ; beneath 

 purplish, with a distinct bronzy-green tinge, and more strongly shining than 

 above. 



Head purplish brown, slightly bronzy green behind clypeus, with two smooth 

 callosities near vertex, and a broad, smooth, longitudinal carina on occiput; 

 front slightly convex; surface coarsely, confluently punctate, becoming rugose 

 toward clypeus, densely clothed with long, recumbent, whitish hairs, intervals 

 densely granulose; clypeus broadly, deeply, arcuately emarginate in front, 

 arcuately rounded on each side. Antenna piceous, subequal in width to apex; 

 intermediate segments compact, wider than long, broadly rounded at outer 

 margins; third segment one and one-half times as long as fourth. 



Pronotum more than twice as wide as long, slightly narrower at apex than 

 at base, widest at middle; sides strongly, arcuately rounded; anterior margin 

 slightly sinuate, with a vague, broadly rounded, median lobe ; base broadly, 

 arcuately emarginate on each side, median lobe moderately produced, and 

 narrowly rounded in front of scutellum ; disk flat, with a broad depression on 

 each side along lateral margin, and a vague, irregular, longitudinal depression 

 on each side of middle line ; surface sparsely, irregularly punctate at middle, 

 becoming confluently punctate at sides, with two small, round, indistinct, smooth 

 spots, and three longitudinal, smooth spaces extending from base to apex. 



Elytra wider at base than pronotum, one and one-half times as long as wide, 

 widest behind middle; sides nearly parallel from humeral angles to behind 

 middle, then arcuately converging to tips, which are separately broadly 

 rounded; lateral margins rather coarsely serrate; basal depressions very deep; 

 humeral depressions moderately deep; disk strongly flattened and uneven; sur- 

 face without distinct pubescence, irregularly punctate on elevated areas, con- 

 fluently foveolate-punctate in depressed areas, each elytron with a distinct,
