AET. 27 NEW BUPRESTID BEETLES FISHER 13 



slightly produced and broadly rounded; base transversely truncate 

 to middle of each elytron, with the median lobe strongly produced 

 and broadly rounded ; disk moderately convex, with a broad, longi- 

 tudinal, median depression extending from apex to base, a broad, 

 oblique depression on each side at lateral margin, a large, round 

 swelling replacing the prehumeral carina near each posterior angle, 

 and with a round, deep fovea between the swelling and basal margin ; 

 surface vaguely rugose toward the sides, rather densely, coarsely, 

 irregularly punctate, and sparsely clothed with short, inconspicuous 

 hairs. Scutellum depressed at middle, without a transverse carina, 

 the surface densely, finely reticulate. 



Elytra as wide as pronotum at base, slightly narrower at base than 

 behind middle; sides slightly expanded behind base, broadly, arcu- 

 ately constricted at middle, arcuately expanded behind middle, then 

 arcuately narrowed to the tips, which are separately narrowly rounded 

 and feebly serrulate; sides of abdomen narrowly exposed above; disk 

 slightly flattened, the sutural margins slightly elevated posteriorly, 

 with broad, deep, basal depressions, and two rather distinct, smooth, 

 longitudinal costae on each elytron, the costae not extending to the 

 base or apex; surface densely, coarsely imbricate-punctate, nearly 

 glabrous. 



Abdomen beneath vaguely granulose, rather coarsely, sparsely 

 punctate, denseh^ marked with transverse, crenulate lines toward 

 the sides of basal segments, and sparsely, uniformly clothed with 

 short, inconspicuous, white hairs; first segment convex at middle, 

 the suture between the first and second segments distinct at the sides ; 

 last segment broadly rounded at apex; vertical portions of the seg- 

 ments densely clothed with long, whitish ]3ubescence; pygidium 

 densely, coarsety punctate, and without a projecting carina at apex. 

 Prosternum vaguely granulose, sparsely, coarsely punctate, sparsely 

 clothed with moderately long, semierect, white hairs, the surface 

 deeply, narrowly, transversely depressed behind the prosternal lobe, 

 which is broad, strongly declivous, and broadly, rather deeply, arcu- 

 ately emarginate in front ; prosternal process broad, the sides parallel 

 to behind the coxal cavities, then obliquely narrowed to the apex, 

 which is acute. Tibiae slightly flattened, anterior pair slightly 

 arcuate, and all pairs unarmed at apices. Posterior tarsi nearly 

 as long as the tibiae, the first joint as long as the following three 

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

 the inner tooth slightly broader and distinctly shorter than the 

 outer one, and not turned inward.
