Distribution: This species occurs in the western part of the 

 state as shown by the following map. The records from Wai 

 lace, Logan and Rooks counties are those of the Kansas State 

 Agricultural College. Van Duzee records it from Colorado and 

 New Mexico. Accordingly Kansas would seem to be the east- 

 ern limit of its range.
