In the Bulletin of the U. S. Geological and Geographical Survey 

 of the Territories, Vol. i, p. 342, 1876, Uhler says: "This is the 

 grandest and most beautiful of the large western species of Cicada. 

 Its note is said to be loud, piercing, and sustained, and from the 

 great strength of the base of the wings and their fascicul?e of 

 muscles the species must be one of the most vigorous and rapid in 

 flight. The specimens here noticed were collected in Colorado by 

 Prof. C. Thomas." 



Dr. Raymond H. Beamer, in an account of his collecting trip 

 in Kansas in 1916, writes that dorsata was the most widely spread 

 and abundant species taken. It was commonly found on low shrubs 

 or weeds and grass, often on barren hill tops.

This species is very common at times in New Mexico, and will no 

 doubt be found abundant in parts of Colorado as well. It is a beau- 

 tiful insect, and is colored near the base of both pairs of wings bright
