basal spot occupviug intervals four and five, a small oval spot in

 in intervals four, five and six, increasing in length from within out- 

 ward, another large spot extending from sixth stria to margin, 

 occupying about the second one-fourth. A large spot commencing 

 at fourth stria opposite posterior dorsal puncture and extending to 

 the margin, and an apical pale spot ; these pale areas may vary as 

 to size and degree of coalescence. 



Head and thorax alutaceous ; elytra sculptured with exceedingly

Head very slightly wider than thorax at apex ; anteunse one-half

 ginate ; median line distinct, abbreviated in front, obsoletely so 

 behind ; transverse impressions well marked ; basal impressions 

 broad and deep, bistriate ; sides evenly arcuate in anterior three-

Elytra oblong-oval, one-half wider than thorax, and scarcely one- 

 third longer than wide ; deeply striate ; striae entire, distinctly 

 punctate to posterior dorsal puncture, then more feebly, becoming
