NORTH AMERICAN BUPRESTID BEETLES 301 



rugae more or less transverse at middle, and becoming irregular 

 toward the sides, sparsely, finely punctate between the rugae, and 

 sparsely clothed with long, recumbent white hairs in the median and 

 lateral depressions. Scutellum transversely carinate, and the surface 

 finely, densely reticulate. 



Elytra wider than pronotum at base, and equal in width at base 

 and behind middle ; sides nearly parallel for a short distance behind 

 base, feebly, broadly constricted in front of middle, broadly, 

 arcuately expanded behind the middle, then obliquely narrowed to 

 the tips, which are separately, broadly rounded, and finely serrulate ; 

 sides of abdomen scarcely exposed above; disk slightly flattened, 

 sutural margins rather strongly elevated posteriorly, and with broad, 

 shallow basal depressions; surface obsoletely granulose, rather 

 densely, finely punctate, more or less transversely, irregularly rugose, 

 and each elytron ornamented with whitish pubescent markings as 

 follows: A vitta extending along the sutural margin from basal 

 depression to middle (sometimes more or less interrupted), then 

 turning obliquely outward toward the lateral margin, and a broad, 

 oblique fascia at apical fourth. 



Abdomen beneath finely, densely reticulate, finely, sparsely punc- 

 tate, the punctures connected transversely by fine, sinuate lines, 

 which are coarser on the basal segment, and sparsely clothed with 

 short, recumbent, white hairs; first segment feebly flattened at 

 middle, and clothed with a few longer, erect hairs; last segment 

 broadly rounded at apex; vertical portions of first segment some- 

 times more densely pubescent than ventral surface; pygidium 

 vaguely punctured but not carinate. Prosternum finely punctate, 

 densely granulose, and sparsely clothed with long, semierect, white 

 hairs; prosternal lobe broad, strongly declivous, and broadly but 

 not very deeply arcuately emarginate in front; prosternal process 

 broad, the sides parallel to behind the coxal cavities, then strongly 

 narrowed to the apex, which is acute. Tibiae slender, and the 

 anterior and middle pairs armed with a feeble tooth on inner margin 

 at apex. Posterior tarsi distinctly shorter than tibiae, and the first 

 joint as long as the following three joints united. Tarsal claws 

 similar on all feet, cleft near the middle, the inner tooth broad, 

 shorter than outer one, and not turned inward. 



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

 tirely brownish cupreous and the lateral margins obliquely expanded 

 from bottom to top; sides of abdomen narrowly exposed above; 

 first abdominal segment more finely punctured and less densely 

 pubescent at middle, and the tibiae unarmed at apex. 



Length, 3.5--1.5 mm.; width, 0.8-1.25 mm. 



Type locality. — North America. Originally described from the 

 Dejean Collection, but present location of type is unknown to writer.
