dian area, margin without serrations; surface moderately shining, 

 median area with moderate close, very shallow punctures, interstices 

 reticulate, appearing subgranulate; median line impunctate, extending 

 slightly past middle, somewhat elevated anteriorly; sides with very 

 low, broad, small asperities becoming granulate near base; vestiture 

 of scanty, fine, appressed hairs. 



Elytra wider than pronotum and 1.90 times as long, 1.39 times as 

 long as wide ; anterior margins rather weakly arcuate, crenulate, with 

 scattered, lunate asperities posterior to it; sides nearly straight and 

 subparallel on less than anterior two-thirds, rather narrowly rounded 

 behind, with margins serrate; surface shining; striae wide and deep, 

 with coarse, close, transverse punctures; interspaces variable, but not 

 wider than striae, rugose-granulate, with granules coarse and uniseri- 

 ate posteriorly; vestiture of small, semierect, inconspicuous hairs on 

 disk, sides, and declivity; declivital granules coarser on interspaces.

Genus RENOCIS Casey 



RENOCIS CHAPINI, new species 



F&male. — Reddish brown, with light cinereous scales and setae; 1.58 

 mm. long, 1.90 times as long as wide; allied to Reiwe'is hrazUiensis 

 Blackman and R. insulans Blackman, but slightly slenderer than 

 either. 



Frons with epistomal margin without visible tooth in median line, 

 fringed with fine yellowish setae ; broadly, shallowly impressed above 

 epistoma, shining, finely punctured below, convex above, subopaque, 

 finely reticulate, finely punctate, with short cinereous hairs and di- 

 vided scales. Eye about three times as long as wide, finely faceted; 

 inner outline scarcely emarginate. Antenna with scape, 5-segmented 

 funicle, and club nearly equal in length; club 1.53 times as long as 

 wide, ovate, with distal end subacuminate, sutures setose and weakly, 

 annularly impressed. 



Pronotum 1.36 times as wide as long, widest near base, basal margin 

 bisinuate, sides strongly arcuate from base to weak constriction just 

 behind the very broadly rounded front margin, which bears a few 

 longer setae; surface reddish brown, weakly shining, finely, closely 

 punctured, finely reticulate, subgranulate; each side with a few very 

 small asperities, variable in number and scarcely visible ; surface partly 

 concealed by numerous small, cinereous scales, often bifurcate, many 

 of those near base nearly white.
