NORTH AMERICAN BUPRESTID BEETLES 259 



punctate between the rugae, and sparsely clothed with short, incon- 

 spicuous hairs. Scutellum not distinctly, transversely carinate, but 

 the surface rather uneven and densely granulose. 



Elytra about as wide as pronotum at base, and slightly wider at 

 base than behind middle; sides nearly parallel and feebly sinuate 

 for a short distance behind base., broadly, obsoletely constricted near 

 middle, feebly, arcuately expanded behind middle, then obliquely 

 narrowed to the tips, which are separately, rather acutely rounded, 

 and feebly serrulate; sides of abdomen narrowly exposed above; 

 disk slightly flattened, sutural margins strongly elevated posteriorly, 

 causing the surface to be feebly, longitudinally concave from basal 

 third to apex, and with broad, moderately deep basal depressions: 

 surface finely, densely imbricate-punctate, and sparsely, uniformly 

 clothed with short, recumbent hairs, which are whitish toward the 

 sides, becoming yellowish and slightly denser toward the sutural 

 margins, and forming a more or less distinct vitta on each elytron 

 extending from basal depression to apex. 



Abdomen beneath obsoletely granulose, rather densely, finely punc- 

 tate, the punctures connected transversely by sinuate lines, which 

 are more distinct on the basal segments, and densely, uniformly 

 clothed with long, recumbent, whitish pubescence; first and second 

 segments feebly, longitudinally flattened, and with the pubescence 

 slightly longer along the middle; last segment broadly rounded at 

 apex; vertical portions of the segments rather densely clothed with 

 long, recumbent, whitish pubescence; p}*gidium sparsely, coarsely 

 punctate, feebly carinate, but the carina not projecting. Prosternum 

 densely, coarsely punctate, and densely clothed with long, whitish 

 pubescence, which extends along middle of body to second abdominal 

 segment; prosternal lobe broad, rather strongly declivous, and 

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

 to behind the coxal cavities, and transversely truncate at apex. 

 Tibiae slender, the anterior pair feebly arcuate, and the anterior and 

 middle pairs armed with a short tooth on the inner margin at apex. 

 Posterior tarsi slightly shorter than tibiae, and the first joint as long 

 as the following two joints united. Tarsal claws similar on all feet, 

 cleft near the apex, the two teeth nearly equal in length, and the inner 

 tooth at most only feebly turned inward. 



Length, 7.5 mm. ; width, 1.9 mm. 



Female. — Differs from the male in having the front of head 

 slightly broader, and the sides more parallel; first and second ab- 

 dominal segments convex at middle and the pubescence not longer 

 than on rest of body; prosternum more sparsely punctate, and the 

 pubescence shorter and sparser ; tibiae unarmed at apex ; and the tar- 

 sal claws cleft near the middle, the inner tooth slightly shorter than 

 outer one, and feebly turned inward.
