 side one sutural, three discoidal and one supra-marginal rows of remote,

 in the female the elytra are flavescent, covered with yellowish scales ; 

 the series of denuded setiferous spots are less conspicuous, and they 

 are disposed on more distinctly costate elevations ; pygidium not 

 scaly in either sex, but the propygidium is clothed with white scales 

 and hairs in the female ; head rugose, clypeus not much elongate, 

 sub-parallel, emarginate at tip, and with the angles distinctly

 stiff bristles similar to those on the disk ; in the male the pygidium
