 with moderately large, not closely placed punctures, intervals alternately 

 more convex especially toward the declivity, surface densely scaly, scales 

 pale-brownish, variegated with darker and paler spots, especially on the 

 more convex intervals, each interval with numerous short, black setae,

 narrower, sides rather strongly arcuate especially at posterior third, lobes 

 very feeble ; disc very feebly convex, sub-rugosely punctate and feebly 

 granulate, sparsely scaly, scales silvery and cupreous and with extremely 

 short inconspicuous setae. Elytra oblong oval, conjointly emarginate at 

 base, burner! rectangular, sides moderately arcuate, disc moderately con- 

 vex, apex rather suddenly declivous, surface striate, striae with moderate, 

 rather closely placed punctures, intervals slightly convex, and alternately
