NORTH AMERICAN BUPRESTID BEETLES 139 



with long, recumbent, whitish pubescence, more golden colored ante- 

 riorly, and nearly concealing the surface; epistoma very wide be- 

 tween the antennae, and deeply, very broadly, arcuately emarginate 

 in front; antennae missing; eyes large, and about equally rounded 

 beneath and above. 



Pronotum one-half wider than long, base and apex about equal in 

 width, and widest near middle ; sides feebly, arcuately rounded from 

 apical angles to basal third, then strongly narrowed to the posterior 

 angles, which are rectangular; when viewed from the side the mar- 

 ginal carina is very strongly sinuate, the submarginal carina feebly 

 sinuate, the two carinae rather widely separated anteriorly, and con- 

 nected to each other at the base; anterior margin rather strongly 

 sinuate, with the median lobe broadly rounded ; base feebly emar- 

 ginate at middle of each elytron, the median lobe very broadly 

 rounded, and subtruncate or feebly emarginate in front of scutel- 

 lum ; disk moderately convex, with a broad, shallow, median depres- 

 sion, feebly divided at middle, and the posterior part slightly more 

 deeply depressed, on each side a broad, deep depression extending 

 along lateral margin from near the apical angles to middle, then 

 obliquely to the base on inner side of prehumeral carina, which is 

 sharply defined, feebly arcuate, and extending from posterior angle to 

 near the middle; surface densely, coarsely, but not deeply, trans- 

 versely rugose, finely punctate between the rugae, sparsely clothed 

 with short, recumbent, whitish hairs, and more densely clothed with 

 longer, golden pubescence in the lateral depressions. Scutellum 

 strongly, transversely carinate, and the surface feebly reticulate. 



Elytra slightly wider than pronotum at base, and distinctly wider 

 at base than at apical third; sides nearly parallel for a short distance 

 behind base, scarcely constricted in front of middle, feebly, arcuately 

 expanded at apical third, then broadly, obliquely attenuate to the 

 tips, which are separately, rather broadly rounded, and finely serru- 

 late; sides of abdomen broadly exposed above; disk rather strongly 

 flattened, the junction of the discal flattened portion with the convex 

 sides of the elytra has the appearance of an obtuse costa, the sutural 

 margins rather strongly elevated toward the apex, and with broad, 

 deep, basal depressions; surface coarsely, densely imbricate-punctate, 

 sparsely clothed with regularly placed short, recumbent, cinereous 

 hairs, and each elytron ornamented with three spots of more densely 

 placed, longer, golden hairs, one in basal depression, one in front of 

 middle, and the other near the apical fourth. 



Abdomen beneath finely, sparsely punctate along the middle, more 

 densely toward the sides, becoming transversely rugose on basal seg- 

 ment, sparsely clothed with short, recumbent cinereous hairs, and 

 with a spot of longer, more densely placed, golden pubescence at the
