N011TH AMERICAN BUPRESTID BEETLES 123 



rounded, and truncate in front of scutellum; disk moderately con- 

 vex, with a broad, rather deep depression in front of scutellum, a 

 vague depression on each side in front of middle, a small, deeper 

 depression on each side along base near posterior angles, a broad, 

 shallow depression on each side along lateral margins, and a more 

 or less distinct, elongate swelling near the posterior angles instead 

 of the prehumeral carina ; surface finely, densely, transversely rugose, 

 finely punctate between the rugae, and sparsely clothed with short, 

 inconspicuous hairs. Scutellum not transversely carinate, and the 

 surface obsoletely reticulate. 



Elytra slightly wider than pronotum at base, and about equal in 

 width at base and apical third ; sides nearly parallel for a short dis- 

 tance behind the base, feebly, broadly, arcuately constricted in front 

 of midde, broadly, arcuately expanded at apical third, then obliquely 

 attenuate to the tips, which are separately, narrowly rounded, and 

 strongly serrulate; sides of abdomen broadly exposed above; disk 

 feebly flattened, without longitudinal costae, the sutural margins 

 rather strongly elevated behind the middle, and with broad, rather 

 shallow, basal depressions; surface densely, coarsely imbricate-punc- 

 tate, and sparsely, uniformly clothed with short, recumbent, whitish 

 hairs. 



Abdomen beneath finely, sparsely punctate along the middle, more 

 denseh r toward the sides, becoming coarsely, transversely rugose on 

 the basal segment, and sparsely clothed with short, recumbent, whit- 

 ish pubescence; first segment broadly concave at middle, the second 

 with a rather broad, deep, smooth groove, which is wider in front 

 than behind, and extending from the anterior margin of segment to 

 near the posterior margin; last segment feebly emarginate or sub- 

 truncate at apex ; vertical portions of the segments not conspicuously 

 pubescent; pygidium strongly carinate, the carina projecting and 

 truncate at apex. Prosternum coarsely punctate, strongly rugose, 

 and sparsely clothed with short, semierect, whitish hairs; prosternal 

 lobe moderately broad, strongly declivous, and broadly rounded in 

 front, with a feeble emargination at the middle; prosternal process 

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

 attenuate to the apex, which is acute. Tibiae slender, nearly 

 straight, anterior and middle pairs with a small tooth on the inner 

 margin at apex, and the posterior pair simple. Posterior tarsi about 

 as long as the tibiae, and the first joint about equal in length to the 

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

 near the middle, the teeth slender, nearly equal in length, and the 

 inner tooth not turned inward. 



Length, 7.5 mm. ; width, 2 mm.
