ART. 31 BUPRESTID BEETLES FROM BOLIVIA FISHER 37 



versely truncate to middle of each elytron, where it is feebly arcu- 

 ately emarginate, then turning obliquely backward to the scutellum, 

 in front of which it is feebly arcuately emarginate ; posterior angles 

 rectangular; surface strongly, broadly depressed at the sides, *the 

 depression extending obliquely from the anterior angles to the base 

 at middle of elytron, then transversely along the base (but not quite 

 as deeply depressed in front of scutellum), causing the antero- 

 median part of the disk to be strongly, regularly convex, with scarcely 

 any elevation near the posterior angles, surface also densely, 

 obsoletely reticulate, and sparsely, irregularly punctate, the punc- 

 tures fine and deep on the convex area, but becoming ocellate-punc- 

 tate in the depressed areas, and from each puncture arises a moder- 

 ately long, recumbent, cinereous or fulvous hair. Scutellum trian- 

 gular, slightly wider than long, with the anterior margin feebly arcu- 

 ately rounded, and the surface densely, obsoletely reticulate. Elytra 

 slightly wider than pronotum at base; humeral angles obtusely 

 angulated; sides nearly parallel to just behind the middle (strongly 

 arcuately emarginate to basal fourth), then obliquely attenuate to 

 near the tips, which are conjointly broadly roimded ; with the lateral 

 margins entire ; humeri very prominent. Each elytron with a broad, 

 moderately deep, transverse depression at base, a broad elongate one 

 between the humerus and lateral margin, and with a distinct lateral 

 carina, which is sinuate, very strongly elevated, and extending from 

 the humeral angle to near the apex, with a single row of closely 

 placed cinereous hairs extending from basal lobe to near the middle 

 of elytron, and with three more or less distinct transverse fasciae, 

 composed of sparsely placed, semierect cinereous hairs arranged 

 as follows: a broad, irregular, indistinct one at base, a narrower, 

 more regular one at middle, and a broad one covering the apical 

 fourth, and between these fasciae the surface is sparsely clothed 

 with inconspicuous semierect black hairs; surface finely and very 

 irregularly punctate, the punctures somewhat stelliform. and the in- 

 tervals obsoletely reticulate and shining. Abdomen beneath sparsely, 

 ocellate-punctate, the punctures large, shallow, open posteri- 

 orly, and from each puncture arises a rather short recumbent cinere- 

 ous hair; intervals finely and densely reticulate; last segment 

 broadly rounded at apex, with the margin entire, and the apical 

 groove deep and following the outline of the posterior margin. 



Length, 3 mm.; width, 1.4 mm. 



Type locality. — Rio Colorado, Bolivia. 



Type.— Ca,t. No. 26985, U.S.N.M. 



Described from a unique male collected at the type locality during 

 September, 1921. This species is named after one of the Indian 

 tribes.
