Frons nearly flat from eye to eye. with a small, shallow pit at center; 

 surface shining, reticulate, finely punctured, vestiture abraded. Eye 

 short oval, inner line entire, facets small. Antenna (pi. 30, fig. 18) 

 with club and scape subequal in length, follicle shorter ; scape rudely 

 club-shaped with a few rather short hairs; club 1.31 times as long as 

 wide, with sutures imperfectly outlined by sparse setae. 



Pronotum 1.11 times as wide as long, widest near base, posterior 

 outline nearly straight, posterior angles slightly rounded; sides 

 weakly arcuate from base to anterior constriction, moderately rounded 

 in front, with six rather weak serrations: anterior area with rather 

 small, sparse asperities, and a few inconspicuous setae; summit mod- 

 erate, at about middle; posterior area horizontal, surface feebly shin- 

 ing, reticulate, with a few fine, shallow punctures and a few incon- 

 spicuous hairs. 



Elytra slightly wider than pronotum and 1.54 times as long, 1.3T 

 times as long as wide; sides subparallel on slightly more than basal 

 half, narrowly rounded behind: surface fairly shining; striae regular, 

 impressed posteriorly, punctures small: interspaces reticulate, rugu- 

 lose, punctures fine, setae short, inconspicuous. Declivity sloping r 

 originating midway of elytra ; striae impressed and punctures as on 

 disk; interspaces slightly convex, each with a row of conspicuous 

 cinereous, erect, broadly spatulate setae or scales.
