NORTH AMERICAN BUPRESTID BEETLES 195 



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

 width at base and behind the middle ; sides nearly parallel or feebly 

 arcuate for a short distance behind the base, broadly, arcuately con- 

 stricted in front of middle, broadly, arcuately expanded behind the 

 middle, then obliquely narrowed to the tips which are separately, 

 rather broadly rounded, and strongly serrulate; sides of abdomen 

 narrowly exposed above; disk slightly flattened, with a vague costa 

 on each side, sutural margins slightly elevated posteriorly, and with 

 broad, shallow basal depressions ; surface coarsely, densely imbricate- 

 punctate, and each elytron ornamented with three more or less dis- 

 tinct yellowish pubescent spots, one in basal depression, one in front 

 of middle, and the other at apical third. 



Abdomen beneath sparsely, finely punctate, the punctures con- 

 nected transversely by obsolete, sinuate lines, which are more distinct 

 at sides of basal segment, and sparsely clothed with short, recumbent, 

 white hairs; first and second segments with a broad, median groove, 

 which is finely punctate, and densely clothed with long, semierect, 

 whitish hairs; last segment broadly rounded at apex; vertical portions 

 of segments not conspicuously pubescent ; pygidium sparsely, coarsely 

 punctate, feebly carinate anteriorly, but the carina not projecting. 

 Prosternum finety punctate, and densely clothed at middle with long, 

 erect, inconspicuous hairs, which extend along middle of body to the 

 posterior margin of second abdominal segment; prosternal lobe broad, 

 feebly declivous, and broadly subtruncate in front; prosternal process 

 broad, the sides strongly expanded behind the coxal cavities, then 

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

 straight, and the anterior and middle pairs with a small tooth on 

 inner margin at apex. Posterior tarsi nearly as long as the tibiae, 

 and the first joint as long as the following three joints united. Tar- 

 sal claws dissimilar, anterior ones cleft near tip, and the teeth nearly 

 equal in length; middle and posterior claws cleft near middle, the 

 inner tooth broad, much shorter than outer one, and not turned 

 inward. 



Length, 4.8 mm.; width, 1.2 mm. 



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

 green, the epistoma cupreous with a roseous tinge, sides of front more 

 parallel, and the surface not distinctly granulose; antennae slightly 

 shorter, and the outer joints scarcely longer than wide; eyes more 

 strongly convex laterally; first and second abdominal segment con- 

 vex, without a longitudinal groove and not clothed with long hairs 

 at middle; prosternum sparsely clothed with long, recumbent, white 

 hairs, but without long, erect hairs at middle ; tibiae without a tooth 

 at apex, and the claws cleft at middle on all feet.
