NORTH AMERICAN" BUPRESTID BEETLES 201 



posed above; disk slightly flattened, sometimes with a vague costa 

 on each side, sutural margins rather strongly elevated posteriorly, 

 and with broad, moderately deep basal depressions ; surface densely, 

 coarsely imbricate-punctate, more or less distinctly clothed pos- 

 teriorly with short, recumbent yellowish or whitish hairs, and each 

 elytron ornamented with more or less distinct yellowish or whitish 

 pubescent spots as follows: one in basal depression, an elongate 

 fascia extending from basal fourth to middle, a round spot at apical 

 third, and sometimes also a small spot exterior to the posterior end 

 of the middle fascia. 



Abdomen beneath finely, densely punctate, the punctures more or 

 less confluent, and rugose on basal segment, rather densely clothed 

 with short, recumbent, whitish or yellowish hairs, and usually with 

 a more or less distinct pubescent spot at the sides of the segments; 

 first segment feebly flattened, without a median groove; last seg- 

 ment broadly rounded at apex ; vertical portions of segments rather 

 densely pubescent, except the second, which is nearly glabrous; 

 pygidium coarsely punctate, feebly carinate, but the carina not 

 projecting. Prosternum densely, finely granulose, and densely 

 clothed at middle with long, erect, fine hairs, which extend to the 

 anterior part of metasternum; prosternal lobe broad, moderately 

 declivous, and broadly, deeply emarginate in front; prosternal 

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

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

 anterior pair slightly arcuate, and the anterior and middle pairs 

 with a distinct tooth on the inner margin at apex. Posterior tarsi 

 slightly longer than tibiae, and the first joint as long as the follow- 

 ing joints united. Tarsal claws nearly similar on all feet, middle 

 and posterior pairs cleft near the middle, the inner tooth broad, 

 shorter than the outer one, and not turned inward, the anterior 

 ones slightly more deeply cleft, and the teeth more equal in size 

 and length. 



Female. — Differs from the male in having the head aeneous or 

 cupreous, front more convex, less closely punctate and the lateral 

 margins more parallel; antennae shorter, and the outer joints 

 scarcely longer than wide; first abdominal segment more convex 

 and sparsely punctured at middle; posterior tarsi not longer than 

 tibiae, and the prosternum not clothed with long hairs at the middle. 



Length, 4.75-8 mm. ; width, 1-1.75 mm.
