NORTH AMERICAN BUPRESTID BEETLES 309 



with short, recumbent, whitish hairs; epistoma slightly transverse 

 between the antennae, and broadly, deeply, arcuately emarginate in 

 front ; antennae extending beyond middle of pronotum, serrate from 

 the fifth joint, and the other joints about as wide as long; eyes mod- 

 erately large, broadly oval, and about equally rounded beneath 

 and above. 



Pronotum nearly one-fourth wider than long, base and apex about 

 equal in width, and widest near middle; sides feebly, arcuately 

 rounded to near the base, where they are nearly parallel ; when viewed 

 from the side the marginal carina is slightly sinuate, the submar- 

 ginal carina a little more sinuate, the two carinae rather widely 

 separated anteriorly and connected to each other near basal fourth; 

 anterior margin strongly sinuate, with a broadly rounded, median 

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

 median lobe broadly rounded, and subtruncate or feebly emarginate 

 in front of scutellum; disk strongly convex, without a median de- 

 pression, but with shallow, oblong, lateral depressions, and moder- 

 ately elevated, straight prehumeral carinae, extending from base to 

 near the middle; surface rather coarsely, transversely rugose, with 

 numerous fine punctures between the rugae, and from each puncture 

 arises a very short, inconspicuous white hair. Scutellum vaguely, 

 transversely carinate, and the surface finely, densely reticulate. 



Elytra as wide as pronotum at base, and about equal in width at 

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

 behind base, broadly, arcuately constricted at middle, broadly, arcu- 

 ately expanded behind the middle, then obliquely narrowed to the 

 tips, which are separately, rather narrowly rounded, and strongly 

 serrulate; sides of abdomen rather broadly exposed above; disk 

 feebly, longitudinally depressed along the sutural margins, and with 

 broad, moderately deep basal depressions; surface rather coarsely 

 imbricate-punctate, and clothed with a few short, inconspicuous, 

 whitish hairs, which are only seen under a high-power lens. 



Abdomen beneath finely, irregularly, transversely striolate, finely, 

 rather densely punctate, and sparsely clothed with short, recumbent, 

 whitish pubescence ; first and second segments broadly, longitudinally 

 concave, the concavity densely punctate, and rather densely clothed 

 with moderately long, inconspicuous, whitish hairs; last segment 

 broadly rounded at apex; vertical portions of the segments not con- 

 spicuously pubescent; pygidium feebly punctate, with a smooth 

 median line, but not distinctly carinate. Prosternum finely, trans- 

 versely rugose, sparsely punctate, and rather densely clothed with 

 long, erect, inconspicuous pubescence, which extends along middle of 

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

 broadly rounded in front; prosternal process broad, the sides nearly
