Hab. Noeth America, Silver City in New Mexico \ Huachuca Mts. 2 and Phoenix in 

 Arizona (coll. L. Bruner). 



This insect, like C. miguelitana, is very variable in size and colour. While the 

 type only measured 19, the Phoenix specimen quoted is 25 millimetres in length. 

 C. neomexicana will certainly be found in the adjacent portion of Mexico. 



[BARYTETTIX, Scudder. 



Barytettix, Scudd. Proc. Amer. Acad. Art. Sci. xxxii. no. 9, p. 397 (Jan. 1897) ; Proc. U.S. Nat. 

 Mus. xx. pp. JO, 27 (1897). 



The members of the genus Barytettix remind one a little of a small Brachystola in 

 their general appearance. The two known species appear to be confined to the Pacific 

 coast region in the vicinity of Cape St. Lucas.
