 ern Saskatchewan, and southern Manitoba south through the Dakotas, 

 Minnesota, Wisconsin, and Michigan and southern Ontario (Wallace- 

 burg) to southeastern Michigan, western and southern Indiana, north- 

 western Ohio, and (probably, formerly) western Kentucky in the east,^°

 Cooke County, and Tascosa).

 casually in winter in northern Louisiana.
