This is a strictly western species, I have seen specimens from Spring 

 Lake Villa, Utaii Co., Utah, Aug. 1-4, Palmer ; Truckee Valley, Nev., 

 Eidgway ; Colorado desert, Cal. (Stanford Univ.) ; Ft. Whipple, Ariz., 

 Palmer ; Mesilla, June 30, Morse, July 4, Cockerell (Morse) and Las 

 Cruces, N. Mex., Cockerell (Bruner) ; Pecos River, Pope, and El Paso, 

 Tex., Morse ; Juarez, Mex., July 3, Morse ; and Sonora, Schott. It was 

 originally described from Nevada and Utah, and besides the States men- 

 tioned above it has been reported from Idaho, Hunter, and Colorado,

This species was occasionally met with by Mr. Morse at El Paso, Tex. 

 on shrubbery along streams and ditches.
