Georgia. J have only males. The smooth but not impressed 

 dorsal line distinguishes this from the allied species. The sides 

 of the thorax are thickly , the disc less densely punctured ; ihe 

 posterior angles , have two distinct carinae. In one specimen , 

 which is possibly a distinct species^ the thorax in less convex, 

 and with the exception of the dorsal line is equally and densely 

 punctured
