NORTH AMERICAN BUPRESTID BEETLES 235 



conceals the sculpture on the front and vertex; epistoma slightly 

 transverse between the antennae, and broadly, deeply, arcuately 

 emarginate in front; antennae extending nearly to middle of pro- 

 notum, serrate from the fifth joint, and the outer joints as wide as 

 long; eyes moderately large, strongly oblong, and equally rounded 

 above and beneath. 



Pronotum slightly wider than long, slightly narrower at base than 

 apex, and widest near apical third; sides arcuately rounded from 

 apical angles to behind middle, then more obliquely narrowed to 

 near the posterior angles, where they are strongly sinuate; posterior 

 angles prominent and slightly acute; when viewed from the side the 

 marginal carina is sinuate, very strongly, arcuately deflexed ante- 

 riorly, the submarginal carina slightly sinuate, and the two carinae 

 widely separated at apical fourth, but connected to each other at 

 apex and near base; anterior margin feebly sinuate, and with a 

 prominent, broadly rounded, median lobe ; base transversely sinuate, 

 with the median lobe broadly rounded, and subtruncate in front of 

 scutellum; disk strongly convex in front, gibbous when viewed in 

 profile, the basal half broadly, transversely depressed, the depression 

 extending along the lateral margins to apical fourth, and with feebly 

 indicated, vaguely sinuate, prehumeral carinae, extending from base 

 to middle of lateral depressions; surface coarsely, concentrically 

 rugose, sparsely clothed with short, recumbent whitish hairs, and on 

 each side a narrow, longitudinal vitta of rather densely placed, re- 

 cumbent, yellowish white hairs, extending from base to middle of 

 elytron forward to posterior margin of gibbosity, then obliquely 

 outward to the apical angles. Scutellum not transversely carinate, 

 but the surface more or less reticulate. 



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

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

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

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

 separately, narrowly rounded, and feebly serrulate ; sides of abdomen 

 very broadly exposed above; disk feebly, longitudinally depressed 

 along sutural margins, which are feebly elevated posteriorly, and 

 with broad, shallow basal depressions; surface coarsely imbricate- 

 punctate, sparsely, uniformly clothed with short, inconspicuous hairs, 

 and each elytron ornamented with a longitudinal vitta of rather 

 densely placed, recumbent, yellowish white hairs, extending along 

 sutural depression from apex to basal depression. 



Abdomen beneath sparsely, coarsely punctate, becoming more or 

 less transversely rugose at sides of basal segments, rather densely 

 clothed with moderated long, recumbent, yellowish white pubescence,
