This species was present, though in small numbers, at Utah Lake in 

 November. A specimen was also shot at the old crater south of Zuui, N. 

 Mex. It probably occurs tlxroughout the entire Middle and Southern 

 Regions, at least during the migrations.

I noticed quite a number of this species on a little stream in Northern 

 New Mexico in November of the past season. It also occurs in Utah.
