 darker in hue. Pronotal angles distinctly subprominent, 

 pronotal lateral margins moderately concavely sinuate ; san- 

 guineous fascia at base blackly punctate, remaining area 

 (excluding that of callosities) coarsely and concolorously

 and also by the presence of the discal linear callosity to the 

 abdomen.
