BEETLES OF THE GENUS RENOCIS — BLACKMAN 399 



Pronotum 1.6 times as wide as long, widest near base, which is 

 very broadly emarginate in median half; sides strongly arcuate 

 behind, constricted anteriorly; front margin very broadly rounded, 

 feebly sinuate in median area; with a weak transverse impression 

 just behind margin, which bears a sparse fringe of erect, spatulate, 

 cinereous setae, slightly shorter in median area; surface reddish 

 brown, shining, finely punctate, reticulate-granulate; at each side 

 with two groups of fine, sharp asperities (3 or 4 in each group), one 

 group on anterior third, the other on posterior half of disk; surface 

 rather sparsely clothed with numerous, small, recumbent, cinereous 

 scales, varying from narrow to broad; with a few erect setae in 

 median line near base. 



Elytra 1.22 times as long as wide, very slightly wider than pro- 

 notum; sides straight and subparallel on anterior two-thirds, very 

 broadly rounded behind ; basal margin strongly elevated between the 

 sixth interspaces, with a continuous, somewhat bisinuate line of 

 teeth, T or 8 on each elytron, and with a smaller tooth just behind 

 margin in each sutural interspace; striae distinctly impressed, about 

 one-half as wide as interspaces, punctures close, moderate in size; 

 interspaces weakly convex, finely rugose-punctate with a few feeble 

 granules, punctures in median line of each interspace slightly larger ; 

 surface reddish brown, shining, partly concealed by rather numerous 

 small, recumbent, yellowish-cinereous scales, most of them rather 

 wide, but those on inner margin of each sutural interspace narrow 

 and hairlike; each interspace with a median row of longer, erect, 

 concolorous scales, or short, wide setae, becoming slightly longer be- 

 hind. Declivity evenly arched, not sulcate, with interspaces slightly 

 narrowed. 



Ventral surface reddish brown, shining, clothed with yellowish- 

 cinereous, recumbent scales, usually bifurcate; last abdominal seg- 

 ment with erect, yellowish-cinereous setae. Foretibia (fig. 18, I) 

 with seven stout teeth on outer margin. 



Male. — Similar in size and general habitus to female, but with the 

 frons strongly concave for entire width, with much longer setae at 

 sides and above; antennal club larger, about 1.8 times as long as wide; 

 pronotum with setae on anterior margin longer, and with asperities 

 greatly reduced or even lacking; teeth on foretibia usually nine in 

 number (fig. 18, m).
