The species has also been reported fiom Colona, Henry County, Illi- 

 nois (McNeill), Topeka, Shawnee County, Kansas (Bruner), L>wa 

 (Osborn), and Dakota (Bruner). McNeill states that the species was 

 to be found at Cordova, Illinois, only '• in a large orchard on the east 

 side of a high hill." 



i*. w. roluerift has been seen by me from Montana, Wyoming, Nebraska. 

 Texas, Arizona, and Mexico; l\ n. uebrascenaiH from all the general 

 regions mentioned excepting Montana, Wyoming, and Arizona. 

 Bruner long ago pointed out the dimorphism. The antennae of S(»uth- 

 ern examples are relatively longer than in those from northern stations, 

 at least in the form /*. n. nehraacenffis.
