ART. 31 BUPRESTID BEETLES FROM BOLIVIA FISHER 13 



pression, and an obsolete longitudinal depression along the sutural 

 margin, which is slightly elevated posteriorly ; surface rather densely 

 and finely imbricate-punctate, and besides the cinereous pubescent 

 spots, is sparsely clothed with very short inconspicuous hairs. Ab- 

 domen beneath finely and sparsely punctate, the punctures becoming 

 denser and more or less connected to each other by striae on the basal 

 segment, and sparsely clothed with rather long recumbent cinereous 

 hairs, which become denser toward the sides; intervals finely and 

 densely reticulate; first segment obsoletely flattened at middle; last 

 segment broadly truncate and feebly emarginate at apex; vertical 

 portion of the segments sparsely clothed with cinereous pubescence; 

 pygidium without a median carina at apex. Prosternum finely, 

 densely punctate, densely granulose, and sparsely clothed with 

 moderately long semi-erect cinereous hairs; prosternal lobe broadly 

 rounded in front and moderately declivous ; prosternal process rather 

 broad, the sides nearly parallel to the apex, which is subtruncate. 

 Femora moderately robust, and not armed with teeth on the inner 

 margin. Tibiae slender, anterior and middle pairs nearly straight 

 and mucronate at apex; posterior pair straight, and strongly ciliate 

 on outer margin near apex. Posterior tarsi three-fourths as long as 

 the tibiae, and the first joint about equal in length to the following 

 three joints united. Tarsal claws similar on all feet, deeply cleft 

 at apex, the teeth about equal in length, and slightly turned inward. 



Female. — Differs from the male in having the head slightly more 

 convex, front aeneous, with a slight cupreous tinge, antennae aeneo- 

 j)iceous, and the prosternum not as densely pubescent. 



Length, 5 mm. ; width, 1.2 mm. 



Ty'pe locality. — Cavinas (Beni River), Bolivia. 



Type, allotype and paratypes. — Cat. No. 26969, U.S.N.M. 



Described from a large series of specimens, all of which were 

 collected at the type locality during January and February, 1922, 

 by William M. Mann and M. R. Lopez. 



This seems to be a very common species and is very uniform 

 in size and coloration. Some of the paratypes have the pronotum 

 and elytra more purplish than in the type, but otherwise they are 

 identical.

Male. — Form rather small, slender and feebly shining; head 

 emerald green in front, brownish-cupreous or aeneo-cuperous on the 

 occiput; pronotum and elytra olivaceous-green, with an obsolete 

 purplish reflection, and each elytron ornated with a rather broad 

 yellow pubescent vitta along the sutural margin, extending from the 

 basal depression to the apex, and broadly interrupted at basal fourth, 

 behind the middle, and at the apical fourth. Beneath aeneo-cupreous.
