The males are a little more shining than the females. With this species 

 I unite granarhis Dej. The larger number of the s)3ecies have tlie thorax 

 regularly narrowing from base to apex, some few however have the 

 base a little narrower than the disc, a little in front of the base, but the 

 transition from one form to the other is very gradual. 



Occurs from the Middle States to Georgia and Texas. 



The three preceding species • have the prosternum horizontal at tip, 

 slightly prolonged and distinctl}^ margined at the sides and apex. They 

 form a very natural group.
