NORTH AMERICAN BUPRESTID BEETLES 327 



fifth joint, and the outer joints longer than wide; eyes large, rather 

 broadly oval, and more acutely rounded beneath than above. 



Pronotum one-third wider than long, slightly narrower at base 

 than at apex, and widest near the middle; sides nearly parallel or 

 feebly, arcuately rounded to basal fourth, then feebly narrowed to 

 the posterior angles, which are rectangular; when viewed from the 

 side the marginal carina is rather strongly sinuate, the submarginal 

 carina straight or feebly sinuate, the two carinae not very widely 

 separated anteriorly, and connected to each other at basal fourth; 

 anterior margin strongly sinuate, with a broadly rounded median 

 lobe; base transversely sinuate to middle of each elytron, with the 

 median lobe feebly, broadly rounded, and subtruncate or feebly emar- 

 ginate in front of scutellum; disk moderately convex, with one or 

 two round, feeble depressions placed longitudinally on the median 

 part, a large, deep depression on each side along lateral margin, and 

 with strongly elevated, slightly oblique, prehumeral carinae, extend- 

 ing from base to near the middle; surface coarsely, transversely 

 rugose, finely, densely granulose and with numerous fine punctures 

 between the rugae. Scutellum transversely carinate, and the surface 

 finely, densely reticulate. 



Elytra wider than pronotum at base, and about equal in width at 

 base and behind middle; sides parallel for a short distance behind 

 base, broadly, feebly constricted near middle, broadly, arcuately ex- 

 panded behind middle, then obliquely narrowed to the tips, which are 

 separately, rather broadly rounded, and finely serrulate; sides of 

 abdomen narrowly exposed above; disk feebly longitudinally de- 

 pressed along the sutural margins, which are strongly elevated pos- 

 teriorly, and with broad, moderately deep basal depressions; surface 

 rather coarsely imbricate-punctate, and clothed with a few short, 

 inconspicuous, whitish hairs, which are more distinct in the basal 

 depressions. 



Abdomen beneath rather densely, finely punctate, becoming irreg- 

 ularly, transversely striolate toward the sides of basal segments, and 

 sparsely, uniformly clothed with short, recumbent, whitish hairs; 

 vertical portions of the segments slightly more densely pubescent 

 than ventral surface; first and second segments broadly, but not 

 deeply, longitudinally concave at middle, and the concavity rather 

 densely clothed with long, semierect, whitish hairs, which point 

 obliquely backward toward the median line of the concavity ; pygid- 

 ium with a smooth median line, but not carinate. Prosternum rather 

 coarsely, sparsely granulose, and rather densely clothed with long, 

 erect, inconspicuous hairs, which extend along the median part of 

 body to the abdomen; prosternal lobe broad, slightly declivous, 

 broadly rounded in front, and with a broad, feeble, arcuate emargina-
