GRASSHOPPERS OF THE CONALCAEA COMPLEX— GURNEY 291 



I have examined a male from Bill Williams Mountain (near 

 Williams), Coconino County, Ariz., in addition to many specimens 

 from Prescott. The intergrades include five males and four females 

 from Hot Air Canyon, Greenlee County, Ariz., taken from a wild 

 turkey by L. L. Hargrave, October 25, 1939. Hebard's original 

 series, which I have seen, also included specimens from Senator, 

 Yavapai County, Ariz., and two localities in the environs of Pres- 

 cott: Mount Union and Granite Peak. Hebard (1935) says that 

 Phoenix, Ariz., material recorded by Bruner (1908) as C. neomexi- 

 cana is in reality coyoterae. 



Other localities given by Ball et. al. (1942) are the Pinal and 

 Hualapai Mountains. I suspect that the Pinal Mountain material 

 may show intergrading characters comparable to those of the Hot 

 Air Canyon series. 



Adults of typical coyoterae collected from July 13 to September 

 14 have been seen. Ball et al. note adults as late as October 3 and 

 say that overwintering occurs in the e^g stage. A series taken at 

 Prescott, July 29, 1933, by Dr. Beamer shows that adults were 

 numerous but that some nymphs could still be found. 



This subspecies is an inhabitant of the chaparral and oak zone 

 of the Upper Sonoran Zone, the entire original series having been 

 taken at an elevation of from 5,400 to 6,500 feet. Hebard (1922) 

 says it is probably strictly geophilous, and Ball et al. say it feeds 

 on low plants such as Eriogonum and Lactuca.

Genotype. — Barytettix crassus Scudder, 1897, by designation 

 of Scudder (1897, December). 



The genus Barytettix has characters noted for the complex and 

 for separating it from Conalcaea. In 1917 Hebard placed Bary- 

 tettix as a synonym of Conalcaea, but the aedeagus had not then 

 been investigated. It shows that two cohesive groups of species 

 are actually represented, supporting the separation suggested by 

 general habitus and color. It is true, however, that the character 

 used by Scudder (shape of mesosternal interspace) to separate 

 the two genera is not dependable. Furthermore, Scudder placed 

 his Conalcaea neomexicana, the type of which I have seen, in the 



" Not to be confused with Barytettix Gunther, 1939, the preoccupied name of a genus of grouse 

 locusts for which Rehn (Ent. News, vol. 59. p. 156, 1948) has proposed a substitute.
