NORTH AMERICAN BUPRESTID BEETLES 149 



distance behind base, very broadly, feebly constricted in front of 

 middle, broadly, arcuately expanded behind middle, then obliquely 

 narrowed to the tips, which are separately, rather broadly rounded, 

 and strongly serrulate; sides of abdomen rather narrowly exposed 

 above; disk feebly flattened, forming a vague longitudinal costa on 

 each elytron, sutural margin slightly. elevated posteriorly, and with 

 broad, deep, basal depressions; surface coarsely, but not deeply 

 imbricate-punctate, vaguely rugose, clothed with a few short, scat- 

 tered, white hairs toward apex, and ornamented with pubescent spots 

 as in nweiventris, but usually only the one at apical third distinct. 



Abdomen beneath finely, densely punctate at middle, more densely 

 toward the sides, becoming rugose or imbricate on basal segment, 

 sparsely clothed with short, recumbent, whitish hairs, and each seg- 

 ment ornamented with a more densely pubescent spot at the sides, 

 which is usually more or less covered with white efflorescence; first 

 segment flattened at middle; second segment with a vaguely de- 

 pressed smooth space at anterior half of middle ; last segment broadly 

 subtruncate at apex; vertical portions of segments not conspicuously 

 pubescent; pygidium coarsely punctate, strongly carinate, the carina 

 strongly projecting and truncate at apex. Prosternum densely, 

 coarsely punctate, and rather densely clothed with moderately long, 

 semierect, whitish hairs; prosternal lobe broad, moderately declivous, 

 and broadly rounded or subtruncate in front; prosternal process 

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

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

 straight, and the anterior and middle pairs armed with a very short 

 tooth on inner margin at apex. Posterior tarsi not quite as long as 

 tibiae, and the first joint as long as the following three joints united. 

 Tarsal claws nearly similar, anterior pair cleft one-third from tip, 

 and the teeth nearly equal in length; middle and anterior claws 

 cleft near middle, the inner tooth slightly shorter than outer one, 

 feebly turned inward, but the tips distant. 



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

 cupreous, slightly wider, and the lateral margins more parallel ; eyes 

 slightly narrower; second abdominal segment without a smooth 

 depression at middle ; last abdominal segment more broadly rounded 

 at apex; anterior tibiae sometimes with a vague tooth at apex, and 

 the tarsal claws similar, cleft near middle, the inner tooth shorter 

 than outer one, and feebly turned inward. 



Length, 5.5-7 mm. ; width, 1.25-1.75 mm.
