NORTH AMERICAN BUPRESTID BEETLES 293 



middle, broadly, arcuately expanded behind middle, then obliquely 

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

 strongly serrulate; sides of abdomen not distinctly exposed above; 

 disk feebly, longitudinally depressed along sutural margins, with 

 feeble indications of a costa on each side, sutural margins elevated 

 posteriorly, and with broad, shallow basal depressions ; surface feebly, 

 coarsely imbricate-punctate, and each elytron ornamental with whit- 

 ish pubescent designs as follows : A rather broad vitta, more or less 

 interrupted, extending along suture from basal depression to middle, 

 then obliquely backward toward lateral margin, and the apical third 

 vaguely pubescent, inclosing a glabrous spot near the suture. 



Abdomen beneath sparsely, finely punctate, the punctures denser on 

 basal segment, connected transversely by more or less distinct sinuate 

 lines, and uniformly, rather densely clothed with short, recumbent, 

 whitish pubescence; first segment slightly flattened at middle, and 

 sparsely clothed with long, erect, inconspicuous hairs; last segment 

 broadly rounded or subtruncate at apex ; vertical portions of segments 

 not conspicuously pubescent ; pygidium coarsely punctate, vaguely 

 carinate, but the carina not projecting. Presternum finely, densely 

 punctate, and sparsely clothed with long, erect, inconspicuous hairs; 

 prosternal lobe broad, rather strongly declivous, and broadly, deeply, 

 arcuately 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, the anterior and middle pairs 

 slightly arcuate, and armed with a short tooth on inner margin at 

 apex. Posterior tarsi slightly shorter than the tibiae, and the first 

 joint as long as the following three joints united. Tarsal claws dis- 

 similar ; claws on each anterior tarsus different, one claw is cleft near 

 the tip, and the teeth nearly equal in length, the opposite claw cleft 

 near the middle, the inner tooth broader and distinctly shorter than 

 the outer one ; middle and posterior claws cleft near middle, the inner 

 tooth broad, shorter than outer one, and not turned inward. 



Length, 5 mm. ; width, 1.25 mm. 



Female. — Differs from the male in having head uniformly dark 

 brownish cupreous, the front nearly equal in width at top and bottom, 

 lateral margins nearly parallel, and the surface coarsely rugose in 

 front, and less pubescent; first abdominal segment convex at middle, 

 and without long pubescence ; presternum without long, erect hairs at 

 middle; tibiae unarmed at apex, and the tarsal claws similar to the 

 posterior claws of male on all feet. 



Redescribed from the male type of subfasciatus in the Museum of 

 Comparative Zoology. 



Type locality. — Illinois (no definite locality given).
