Distribution. Van Duzee reports this species from Ontario, Con- 

 necticut, New York, Pennsylvania, North Carolina, Georgia, Illi- 

 nois, Michigan, Iowa and Missouri. Specimens having been taken 

 at Kansas City, Mo., it is sure to occur in Kansas. 



Subgenus Xantholobus Van Duzee. 



In this subgenus the pronotum is distinctly inflated posteriorly. 

 It is represented in Kanas by a single species.
