Loeufitn vcrrnciddtiis Kiuhy, Faun. Bor. Aiiier., IV, 1837, p. 250. 



Eight males, one female. Pine (xrove July 16 and 23; Platte Canyon

This is even a more noisy species than C undulatus. The}^ fl}^ dur- 

 ino- the hottest part of the daj' and the sharp crackling noise made by 

 their wings may be heard for long distances. On quiet daj's 1 have 

 distinctly heard them for almost or quite half a mile. Often thev will 

 remain suspended almost stationary in the air, making the welkin ring 

 with their shrill crackling.

One female at Victoria, Texas on July 10, and many specimens of 

 both sexes, ]K)th mature and immature, in Colorado at Denver, Golden, 

 and Fort Collins from June 7 to August 10. 



This is apparentl}^ not a common insect in southern Texas, though 

 farther north it is very common, as indicated by the above records. 

 At Victoria 1 saw ])ut the one specimen and no nymphs.
