This is an exceedingly common species over the larger part of 

 the eastern United States. At Ithaca it abounds everywhere. 

 At Saranac Inn I found it most common about the trashy 

 borders of the deeper ponds. I have bred the species at the fol- 

 lowing dates and places: Saranac Inn July 8, 1900, Galesburg 

 111. June 30, 1895.
