 Benton and Montgomery Counties. In Montgomery County, I found sev- 

 eral large colonies in ballast, and on the right of way of the Monon 

 Railroad about 2 miles south of New Richmond. Apparently well estab- 

 lished here. Fassett reports a specimen from Lake County collected by 

 Umbach which is now in the herbarium of the University of Wisconsin.
