 states. Three $ $ and six 9 9 have been collected at Omaha, 

 Douglas County, and Lincoln, Lancaster County, from July

 Louisana Bull. No. 93, 34 (1907). 



This species presents many variations and consequently is 

 difficult to define. It is likely to be confused with C. striatus. 

 Fifteen 9 9 have been collected at the following localities: 

 Cams, Keya Paha County; Halsey, Thomas County, and 

 Haigler, Dundy County, from July 8th to August 19th.

Only four 9 9 are present in the University collection, and 

 all of these were taken around Lincoln, Lancaster County, 

 from June 28th to August 4th. Evidently it is not a very 

 common species.
