Type, allotype, and paratypes. — Cat. No. 41002, U.S.N.M. Para- 

 types also in the collections of W. Knaus, W. J. Chamberlin, C. A. 

 Frost, J. N. Knull, and the University of Kansas. 



Described from a large series of adults (one type), from the locali- 

 ties listed above. 



This subspecies has been reared from galls on Hazel (Coryhts ros- 

 trata and Coiylus mnericmva) , and the adults have been collected a 

 number of times on these plants, but have been recorded in the 

 literature under politus. Obenberger in describing his canadensis 

 has misidentified this subspecies as politus Say, and probably did not 

 have the true politus before him at that time. The males have the 

 genitalia similar to those of politus, and can be separated from that 

 species by the characters given above, but it will be difficult to sepa- 

 rate the females, as no valid characters were found for differentiating 

 them.
