 surflice finely granulose-strigose, somewhat closely punc-

 the middle of the disk. Elytra broader than the thorax, 

 ovate, convex, regularly punctate-striate, interspaces shin-

 piceo-fulvous, four anterior thighs piceous, hinder pair 

 fusco-teneous.

Elongato-ovata, convexa, nitida, subtus nigra, pedibus 

 piceis, femoribus posticis cyaneo-micantibus ; supra cyanea, 

 antennis nigris, basi fulvis ; thorace transverso, subconico, 

 subremote punctato ; elytris regulariter punctato-striatis, 

 interspatiis tenuiter, remote punctatis, disco exteriori et ad
