 migrating on both sides of the forty- third parallel, and appeared May 

 6 at Portage la Prairie, Manitoba. In the fall of 1884 it was first seen 

 at Emporia, Kans., September 20, and was common the. same day.

 April 3; Saint Louis, Mo., April 6; Paris, 111., April 19 j Heron Lake,

 the first came to Emporia, Kans., September 16, and to Shawnee- 

 town, 111., October 3. The last left Lanesboro. Minn., November 9, and 

 Saint Louis, Mo., October 27. Mr. Lloyd states that it is tolerably
