Writing of this species from Foss, western Oklahoma, in Au- 

 gust, 1916, Miss Anna Bennett says: "The cicadas have all disap- 

 peared except the white-sided ones. These are very numerous here 

 this year. In fact they are almost a pest. They sing in the even- 

 ing and early part of the night. In the morning they are usually 

 rather stupid and sleepy and are in the short weeds and grass out 

 from the trees for a few rods, but start up with a loud noise and are 

 quite easily caught in a net or even in the hands. They always fly 

 for the trees and often sing after they light for a short time." Miss 

 Bennett sent me 302 specimens of dealbata, well justifying her state- 

 ment that the " white-sided ones " were very numerous about Foss, 

 Oklahoma, in 191 6. 



Dr. Raymond H. Beamer writes that he found this species asso- 

 ciated with dorsata in Kansas.
