ART. 31 BUPRESTID BEETLES FROM BOLIVIA FISHER 7 



becoming much coarser, very irregular in shape, and confluent in 

 the frontal depressed area, bottom of the punctures finely, densely 

 granulose, and sparsely clothed with long semierect cinereous hairs ; 

 eyes large, strongly convex, more broadly rounded at bottom than 

 on top, and separated from each other on the occiput by about one- 

 half of the distance l>etween the antennal cavities; epistoma feebly 

 and broadly arcuately emarginate in front, the lobes on each side 

 only feebly rounded; antennae very short, the third joint about as 

 long as the following four joints united. Pronotum strongly trans- 

 verse, two times as wide as long, slightly narrower in front than be- 

 hind; sides strongly obliquely expanded to apical fifth, then parallel, 

 or at most, only obsoletely arcuate to the posterior angles, which are 

 acute; anterior margin nearly truncate; base deeply arcuately emar- 

 ginate on each side at elytral lobe, and with a large broadly rounded 

 median lobe : surface feebly, regularly convex, with a broad obsolete 

 dej)ression in front of scutellum, feebl3^ transversely rugose, with a 

 few very fine, irregularly placed punctures between the rugae on 

 disk, the punctures becoming denser and coarser on the antero-lateral 

 region, the bottom of the punctures obsoletely granulose and with a 

 pitlike depression at the center, the intervals obsoletely granulose. 

 Scutellum very small, triangular; surface finely granulose, with a 

 deep fovea at the middle. Elytra distinctly wider than pronotum at 

 base ; sides obtusely rounded at the humeral angles, parallel to just be- 

 hind the middle (feebly concave at basal third), then obliquely atten- 

 uate to the tips, which are acutely rounded, lateral margins coarsely 

 serrate to near the middle, the teeth large and rather evenly spaced 

 except at apex; humeri not prominent; base strongly angularly 

 lobed; surface sparsel}^ and finely punctate, the punctures very fine 

 and widely separated on the disk, becoming coarser, more confluent 

 and somewhat transversely rugose toward the lateral margins and in 

 the depressed green areas, and without longitudinal costae, intervals 

 smooth; each elytron with a deep basal depression, a more shallow 

 one at humerus, and with the green spot on disk broadly but feebly 

 depressed. Abdomen beneath sparsely, coarsely and regularly punc- 

 tate on the median parts, becoming very finely and densely punctate 

 on the antero-lateral areas of the segments, where the surface is also 

 densely clothed with long recumbent cinerous hairs; intervals 

 smooth ; first segment obsoletely concave at the middle ; last segment 

 with a broadly rounded obsolete median carina, the lateral margins 

 entire, and without a submarginal ridge; apex broadly rectangularly 

 emarginate, the emargination deep, feebly sinuate at middle, the sides 

 rounded at bottom and j^roduced into a long sharp tooth at apical 

 angles. Prosternum with a narrow, broadly rounded median lobe in 

 front, and the anterior margin elevated; surface feebly transversely
