NORTH AMERICAN BUPRESTID BEETLES 47 



foveae; surface coarsely, densely rugose, rather densely, coarsely 

 punctate between the rugae, and sparsely clothed behind the epistoma 

 with long, recumbent, yellowish hairs; epistoma not transverse be- 

 tween the antennae, slightly elevated, and broadly but not deeply, 

 arcuately emarginate in front; antennae extending beyond middle 

 of pronotum, serrate from the fourth joint, and some of the outer 

 joints longer than wide; eyes large, elongate, and equally rounded 

 above and beneath. 



Pronotum nearly three-fourths wider than long, about equal in 

 width at base and apex, and widest at middle ; sides rather strongly 

 arcuately rounded from apical angles to base; when viewed from 

 the side the marginal and submarginal carinae are slightly sinuate, 

 rather narrowly separated anteriorly, and connected to each other 

 behind the middle ; anterior margin slightly sinuate, and the median 

 lobe only feebly indicated ; base feebly, broadly emarginate at middle 

 of each elytron, with the median lobe strongly, broadly rounded, 

 and truncate in front of scutellum; disk irregularly convex, with a 

 broad, deep depression on each side along lateral margin, extending 

 nearly to the median line, which is broadly, deeply concave from 

 anterior margin to base except at the middle, where it is strongly 

 interrupted, and without prehumeral carinae; surface densely, 

 deeply, transversely rugose, rather densely, coarsely punctate be- 

 tween the rugae, and sparsely clothed with short, semierect hairs 

 toward the sides. Scutellum feebly, transversely carinate, and the 

 surface finely, densely reticulate. 



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

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

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

 broadly expanded behind the middle, then obliquely narrowed to the 

 tips, which are separately, broadly rounded, and finely serrate ; sides 

 of abdomen narrowly exposed above; disk slightly flattened, sutural 

 margins slightly elevated posteriorly, and with broad, deep basal 

 depressions; surface densely, finely, acutely granulose. 



Abdomen beneath obsoletely granulose, glabrous, densely, finely 

 punctate, the punctures coarser on the basal segment and more or 

 less connected transversely at sides of the segments; first segment 

 convex at middle; last segment broadly rounded at apex; vertical 

 portions of the segments sparsely clothed with short, recumbent, 

 yellowish hairs; pygidium sparsely, coarsely punctate, feebly cari- 

 nate, but the carina not projecting. Prosternum obsoletely granulose, 

 coarsely punctate, somewhat rugose, and sparsely clothed with short, 

 semierect, yellowish hairs; prosternal lobe rather narrow, slightly 

 declivous, and broadly, feebly, arcuately emarginate or subtruncate 

 in front; prosternal process broad, the sides nearly parallel to be- 

 hind the coxal cavities, then obliquely narrowed to the apex, which
