The song of this species continues for some time and somewhat 

 resembles the sound produced by Neoconocephahis retusus or N. ro- 

 bustus, two of the large, long-horned katydid-like insects. Though 

 we have not been able to collect them, we have heard cicadas of the 

 genus Okanagana singing on Crow's Nest Mt., West Point, N. Y., 

 on June 15, 1913, and again on June 13, 1914, and Col. Wirt Robinson 

 collected a pupa-skin on the same mountain. We have also heard 

 them singing in Letchworth Park, Portage, N. Y., June 13, 191 5; 

 near Potter's Swamp, Yates Co., N. Y., June 14, 191 5, and in Egles- 

 ton's Glen on the east side of Lake Keuka, N. Y., June 15, 191 5.
