NORTH AMERICAN BUPRESTID BEETLES 197 



expanded near middle, transversely depressed behind epistoma, and 

 with a broad,, shallow depression near the vertex; surface coarsely 

 rugose, the rugae irregular on the front, becoming longitudinal on 

 the occiput, rather densely, coarsely punctate between the rugae, and 

 sparsely clothed with long, recumbent, yellowish pubescence behind 

 the epistoma; epistoma strongly transverse between the antennae, 

 rather strongly elevated, and broadly, deeply emarginate in front; 

 antennae extending nearly to posterior angles of pronotum, serrate 

 from the fourth joint, and the outer joints distinctly longer than 

 wide; eyes large, rather narrowly oblong, and slightly more acutely 

 rounded beneath than above. 



Pronotum slightly wider than long, base and apex about equal in 

 width, and widest near the middle ; sides feebly, arcuately rounded an- 

 teriorly, and more strongly narrowed behind the middle ; when viewed 

 from the side the marginal and submarginal carinae are strongly 

 sinuate, narrowly separated anteriorly, and connected to each other 

 near the middle; anterior margin strongly sinuate, with the median 

 lobe broadly rounded; base feebly emarginate at middle of each 

 elytron, the median lobe broadly rounded, and feebly emarginate in 

 front of scutellum; disk moderately convex, feebly, broadly, trans- 

 versely concave on basal half, a round, median depression near an- 

 terior margin, a broad, oblique depression on each side along lateral 

 margin, and with distinct straight prehumeral carinae, extending 

 from posterior angles to near the middle; surface shining, densely, 

 coarsely rugose, the rugae more or less transverse at middle, becoming 

 oblique toward the sides, obsoletely granulose, rather densely, finely 

 punctate between the rugae, and sparsely clothed with moderately 

 long, recumbent, whitish or yellowish hairs at the sides. Scutellum 

 strongly, transversely carinate, and the surface densely, finely 

 reticulate. 



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

 width at base and behind the middle; sides feebly rounded behind 

 the base, broadly, arcuately constricted in front of middle, broadly, 

 arcuately expanded behind the middle, then obliquely narrowed to 

 the tips, which are separately, rather broadly rounded, and finely 

 serrulate; sides of abdomen narrowly exposed above; disk slightly 

 flattened at middle, with a short, vague costa on each side, sutural 

 margins slightly elevated posteriorly, and with rather shallow, broad, 

 basal depressions; surface densely, coarsely imbricate-punctate, 

 sparsely, uniformly clothed on apical fifth with very short, white 

 hairs, and each elytron ornamented with whitish pubescent spots as 

 follows; a large spot in basal depression, a narrow fascia extending 

 from basal fourth to middle, exterior to the posterior end of which 

 is a small round spot, and a larger round spot along suture near 

 apical third.
