Southern States, Georgia and South Carolina ; rare, under 

 pine bark. The arcuated elevated line each side in the front 

 part of the thorax touches the apical margin, and incloses the 

 extremity of the longitudinal costa which limits the great dorsal 

 excavation; this excavation is marked besides with a medial 

 costa, which attains neither the apex nor the base.

 cornubus duobus brevibus ad apicem et tuberculis duobus ante medium 

 armato, elytris versus basin rufescentibus, parce punctulatis et subtiliter
