NORTH AMERICAN BUPRESTID BEETLES 43 



of each elytron, the median lobe broadly rounded, and transversely 

 truncate in front of the scutellum; disk moderately convex, with 

 two deep, broadly rounded depressions on the median line, one near 

 the anterior margin, the other in front of scutellum, with a very 

 broad, deep depression on each side, extending obliquely from the 

 lateral margin to near the median line, and with short, obtuse ele- 

 vations in place of prehumeral carinae; surface coarsely, densely, 

 transversely rugose, and sparsely punctate between the rugae. Scu- 

 tellum transversely carinate, and the surface finely, densely reticulate. 



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

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

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

 feebly expanded behind middle, then arcuately narrowed to the tips, 

 which are separately, rather broadly rounded, and finely serrulate; 

 sides of abdomen narrowly exposed above; disk slightly flattened, 

 sometimes with a very vague trace of costa, sutural margins slightly 

 elevated behind middle, and with broad, moderately deep basal 

 depressions; surface densely finely granulose. 



Abdomen beneath obsoletely granulose, finely, sparsely punctate, 

 the punctures more or less connected transversely by sinuate lines, 

 which are coarser on the two basal segments, and sparsely clothed 

 with short, inconspicuous hairs; first segment vaguely flattened at 

 middle; last segment broadly rounded at apex; vertical portions of 

 segments not conspicuously pubescent; pygidium sparsely, coarsely 

 punctate, and only vaguely carinate anteriorly. • Prosternum sparsely 

 punctate, more or less granulose, and sparsely clothed with long, 

 erect, fine hairs; prostemal lobe broad, moderately declivous, and 

 broadly but not deeply, arcuately emarginate in front; prosternal 

 process rather broad, the sides parallel to behind the coxal cavities, 

 then obliquely narrowed to the apex, which is acute. Tibiae slender, 

 anterior pair with a very short tooth on inner margin at apex, middle 

 and posterior pairs simple. Posterior tarsi slightly shorter than 

 tibiae, and the first joint about as long as the following three joints 

 united. Tarsal claws similar on all feet, cleft near middle, the teeth 

 nearly equal in length, and the inner tooth turned inward. 



Female. — Differs from the male in having the first abdominal seg- 

 ment more convex at middle; anterior tibiae unarmed at apex, and 

 the prosternum not clothed with long, erect hairs at middle. 



Length, 5-6.25 mm. ; width, 1.3-1.9 mm.
