 must be retained. Fabricius has erroneously cited the

The 



coleoptra form an oblong square, of a fine fulvous red 

 color, darker toward the tip, serrated on the outer edge, 

 which, with the suture, is elevated. Four elevated lines 

 on each elytron, the first one, next the suture, forked at 

 the base, and the third interrupted in the middle. These 

 ridges and the margin are ornamented with dark purplish
