ART. 31 BUPRESTID BEETL.ES FROM BOLIVIA FISHER 5 



short and robust, the third joint about as long as the following four 

 joints united. Pronotum strongly transverse, two times as wide as 

 long, base and apex about equal in width, widest at apical fourth; 

 sides strongly obliquely expanded to apical fourth, where they are 

 obtusely angulated, then obliquely attenuate to the posterior angles, 

 which are obtuse (in some specimens the sides are feebly sinuate be- 

 hind the apical fourth) ; anterior margin broadly arcuately emargi- 

 nate, with an obsolete broadly rounded median lobe; base strongly 

 tircuately emarginate on each side at the elytral lobe, the median lobe 

 broadly rounded and narrowly truncate in front of the scutellum; 

 surface feebly convex and obsoletely uneven, with a more distinct 

 broad depression along lateral margin at apical third, and a similar 

 one in front of elytral lobe, finely, rather densely and regularly 

 punctate, sometimes becoming obsoletely transversely rugose toward 

 the sides, the intervals smooth. Scutellum triangular, the three sides 

 about equal in length, with the surface finely, densely granulose. 

 Elytra distinctly wider than pronotum at base ; sides broadly rounded 

 at humeral angles, parallel to just behind the middle (feebly concave 

 at basal third), then arcuately attenuate to the tips, which are rather 

 acutely rounded, lateral margins finely serrate to basal third ; humeri 

 feebly developed; base strongly angularly lobed; surface densely, 

 finely, and regularly punctate, and the intervals smooth ; each elytron 

 with two more or less distinct longitudinal costae, one parallel to the 

 sutural margin, and extending from the apex to middle, the other 

 along the lateral margin, extending from behind the humerus to the 

 apex, where it is connected to the other costa. Abdomen beneath 

 coarsely and irregularly punctate, the punctures widely separated on 

 the median parts, but becoming denser and finely rugose on the 

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

 densely clothed with long recumbent cinereous hairs; intervals 

 smooth ; first segment not distinctly concave at middle ; last segment 

 convex, or with an obsolete broadly rounded carina at middle, the 

 lateral margins variable, entire or with a more or less abrupt emargi- 

 nation on each side near the apex, and without a submarginal ridge ; 

 the apex with two deep semi-circular emarginations. Prosternum 

 truncate in front, with the anterior margin strongly elevated; sur- 

 face narrowly, transversely depressed behind the anterior margin, 

 coarsely, very densely punctate, and sparsely clothed with long 

 recumbent cinereous hairs toward the sides; prosternal process flat, 

 strongly expanded behind the coxal cavities, and with a very large 

 triangular tooth at apex. Femora robust; anterior pair strongly 

 swollen at middle, with a large obtuse triangular tooth on the outer 

 margin, closer to the apex than base, and feebly serrate on the ex- 

 terior margin ; middle pair slightly swollen at middle ; the posterior 

 pair subcylindrical, and feebly flattened. Anterior tibiae feebly
