Frons with epistomal margin bearing a median sharp point, with 

 a fringe of cinereous setae covering most of mandibles; with an 

 arcuate transverse impression just behind the epistoma, which ig 

 widened in median area to a point well above the eyes, forming a 

 median concavity; elevated at sides and above; surface brown, shin- 

 ing, finely punctate in concavity, finely and closely granulate-punctate 

 at sides and above; clothed with moderately long, rather coarse, 

 testaceous setae, more abundant at sides and above. Eye finely granu- 

 late, more than 3 times as long as wide, the inner margin rather 

 weakly sinuate. Antenna (fig. 17, d) with club 2.22 times as long 

 as wide, shorter than the remaining visible part of antenna, with 

 3 nearly straight sutures marked by annuli and rows of setae. 



Pronotum about 1.4 times as wide as long, widest near base, which 

 is broadly, shallowly emarginate; sides strongly arcuate from base 

 to transverse impression just behind anterior margin, which is feebly, 

 broadly sinuate in median area; surface reddish brown, moderately 

 shining, very finely and densely punctate, the interspaces minutely 

 reticulate-granulate; each side with two groups of rather high, 

 slender asperities, with anterior group near transverse impression 

 usually two in number, the posterior group usually four in number 

 and nearly midway between anterior and posterior margins ; surface 

 clothed with small recumbent scales, light cinereous except for a small 

 area of fulvous scales at each side involving both groups of asperities ; 

 anterior margin with a sparse fringe of fulvous setae, shorter than 

 in most species of Renocis. 



Elytra 1.2 times as long as wide, slightly wider than pronotum; 

 sides straight and subparallel on anterior two-thirds, very broadly 

 rounded behind with combined apices appearing broadly emarginate 

 in median area; basal margins strongly elevated from first to fifth 

 interspace, gradually becoming lower laterally, with six or seven 

 crenulations on each side; first stria impressed, the others not at 

 all or very feebly impressed, punctures rather coarse, wider than long 

 and very closely placed as seen in denuded specimens; interspaces 

 nearly flat, finely rugose-punctate, each with a sparse median row of 

 slightly larger punctures, sometimes accompanied by feeble gran- 

 ules, surface almost completely concealed by numerous small, semi- 

 recumbent, cinereous scales, which mask even the striae, each inter- 

 space with a median row of short, stout, erect, fulvous setae, longer 

 on the declivity; each elytron with a dense group of erect, brown 

 setae just behind the basal elevation. Declivity steep, very broadly 

 sulcate in the sutural area between the third interspaces of the elytra ; 

 third interspfice elevated, with a few feeble granules, the median 

 row of setae nearly lacking on interspaces 1 and 2 and replaced by 

 a double row of longer, coarser setae on third interspace, causing the
