NORTH AMERICAN BUPRESTID BEETLES 105 



feebly, arcuately expanded at the middle, and with a narrow, longi- 

 tudinal groove extending from the occiput to the epistoma; surface 

 finely, closely rugose, rather densely, finely punctate, and densely 

 clothed with long, recumbent, golden yellow hairs, except on the ver- 

 tex and along upper half of the eyes; epistoma rather wide between 

 the antennae, and broadly, arcuately emarginate in front; antennae 

 extending to middle of pronotum, serrate from the fourth joint, and 

 the outer joints as wide as long; eyes rather large, narrowly oblong, 

 and about equally rounded above and beneath. 



Pronotum at least one-half wider than long, the base and apex 

 about equal in width, and widest at middle; sides strongly, arcuately 

 rounded ; when viewed from the side the marginal carina is strongly 

 sinuate, the submarginal carina nearly straight, the two carinae 

 rather widely separated anteriorly, and connected to each other be- 

 hind the middle; anterior margin strongly sinuate, with a broadly 

 rounded median lobe; base distinctly emarginate at middle of each 

 elytron, the median lobe broadly rounded, and subtruncate in front 

 of scutellum; disk moderately convex, with a broad, shallow, median 

 depression extending from base nearly to apex, a broad, shallow de- 

 pression on each side along lateral margin, and without prehumeral 

 carinae; surface closely, coarsely rugose, the rugae oblique in front, 

 transverse near the base, finely punctate between the rugae, with a 

 median band of golden pubescence extending from base to anterior 

 margin, and a broader band of similar pubescence along the lateral 

 margins, the hind angles sometimes not pubescent. Scutellum usually 

 feebly, transversely carinate, and the surface finely reticulate. 



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

 at base and apical third, deeply, broadly, arcuately constricted in 

 front of middle, and arcuately attenuate from apical third to the 

 tips, which are separately, broadly rounded, and strongly serrulate ; 

 sides of abdomen broadly exposed above ; disk slightly flattened, with- 

 out trace of costae, the sutural margins slightly elevated near apex, 

 and the basal foveae broadly, and rather deeply impressed; surface 

 finely, densely imbricate-punctate, and not pubescent. 



Abdomen beneath finely punctate and granulose, sparsely along 

 the median line, more densely at the sides, especially on the first two 

 segments, which are also slightly rugose, rather densely clothed 

 with short, recumbent, whitish hairs; vertical portions of the 

 segments densely clothed with golden yellow pubescence; first seg- 

 ment slightly flattened at middle and rugose, the second with a 

 feeble longitudinal depression; last segment obtuse or truncate at 

 apex; pygidium coarsely punctate, strongly carinate, the carina pro- 

 jecting and truncate at apex. Presternum finely, densely punctate, 

 somewhat rugose, and sparsely clothed with short, whitish hairs;
