A species widely distributed in the eastern United States, and 

 often locally very abundant. It is common at Ithaca about the 

 Cascade pond during July, and about the hatchery grounds at 

 Saranac Inn during the same month. I have bred the species at 

 the following dates and places: Lake Forest 111. May 31, 1899; 

 Saranac Inn N. Y. July 15, 1900.
