ART. 31 BUPRESTID BEETLES FROM BOLIVIA FISHER 27 



regularly transversely rugose on the disk. Scutellum triangular, 

 acute at apex, with the surface densely and coarsely granulose. 

 Elytra with the sides slightly rounded behind the humeral angles, 

 feebly broadly arcuately constricted at middle, then broadly arcuately 

 expanded at apical fourth, and finally arcuately attenuate to the tips, 

 which are separately broadly rounded, with the lateral margins entire ; 

 humeri rather strongly developed ; each elytron with a broad, moder- 

 ately deep basal depression, with a short straight lateral carina extend- 

 ing from humerus to middle of elytron, and with the suture elevated 

 from basal third to apex; surface opaque, densely, coarsely granu- 

 lose, with numerous short transverse elevations, which are irregularly 

 placed and more shining than the intervals. Abdomen beneath 

 densely and rather coarsely granulose, and rather densely punctate, 

 the punctures large, very shallow, and nearly obsolete, and sparsely 

 clothed with very short, inconspicuous hairs. 



Length, 3.75 mm. ; width, 1 mm. 



Type locality. — Eosario (Lake Kogagua), Bolivia. 



r?/;?e.— Cat.^No. 26977, U.S.N.M. 



Described from a unique male collected at the type locality during 

 November, 1921. 



PARAGRILUS HOLOMELAS. new species 



Narrowly elongate, uniformly piceous above and beneath, and 

 strongly shining. 



Head feebly convex and only obsoletely flattened behind the epis- 

 toma, with a round, moderately deep depression on the front, and 

 a broad longitudinal groove on the vertex, the groove not extended 

 on the occiput; surface densely, coarsely granulose, with a few 

 large, obsolete punctures intermixed, the punctures shallow, irreg- 

 ular in shape, and becoming more closely placed behind the epistoma, 

 where the surface is also rather densely clothed with short, recum- 

 bent, scale-like cinereous hairs ; antennal cavities narrowly separated 

 on the front ; epistoma broadly, deeply arcuatel}' emarginate in front. 

 Pronotum moderately, regularly convex, slightly wider than long, 

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

 sides when viewed from above arcuately expanded from anterior 

 angles to apical third, where they are broadly rounded, then feebly 

 obliquely attenuate to the posterior angles, which are rectangular; 

 anterior margin bisinuate, with the median lobe broadly rounded; 

 base strongly angularly emarginate on each side, with the median 

 lobe moderately produced, and broadly subtruncate in front of scu- 

 tellum; surface with a broad, very deep depression, extending ob- 

 liquely from near the apical angles to the basal emargination, then 

 transversely along the base, the groove more deeply impressed at 

 the posterior angles, in front of which is a broadly rounded eleva-
