Distribution. — (Map 4.) This is a widely occurring species, 

 found from the Appalachian Highlands of Canada (?) and the eastern 

 Interior Plains through much of the Atlantic Plain, south and west 

 to the southern portions of the Intermontane Plateau Systems of 

 Mexico. One rather disjunct locality in North Dakota may represent 

 only a very local and perhaps temporary infestation.
