GEASSHOPPERS OF THE CONALCAEA COMPLEX— GURNEY 295 



has been noted, the slight differences observed being mainly due 

 to warping in drying. The supra-anal plate (fig. 64, m) has the 

 height of lateral prominences slightly variable. When the aedea- 

 gus is extracted and allowed to dry in situ, the basal lobe is likely 

 to curl, so that the resulting lateral view does not agree with the 

 wet condition (fig. 64, a). The posterior view demonstrates en- 

 tirely diagnostic characters, however, in either wet or dry prepa- 

 rations. The four female paratypes vary in pronotal length from 

 6.3 to 7 mm. and in body length from 29 to 31 mm. In two of the 

 females the cercus is less acute than in the allotype (fig. 58, 6), 

 though still sharply triangular. The subapical portion of the 

 dorsal valve of the ovipositor is scarcely curved, showing some 

 difference from humphreysii in this respect (fig. 58, /, A:) . I have 

 not found the shape of cercus and ovipositor sufficiently helpful 

 as separating characters, however, to include them in the key to 

 species. 



In general coloration there is a variable intensity of the oliva- 

 ceous-green, a few specimens being more brownish, with yellow 

 thoracic markings nearly the same shade as the background color. 

 About half of the series has the lateral pronotal lobe as in plate 11, 

 figure 2, the other having an additional yellow mark as in the 

 holotype. In some it is indistinct, showing the feature to be vari- 

 able. The lower half of the pagina on the exterior face of the 

 hind femur is dull straw color, rather than a distinct yellow, in 

 all the female partypes, and in two of the males that area is green- 

 ish yellow and blends gradually wfth dark greenish brown on the 

 dorsal half of the pagina. Nine of the males are decidedly K-eddish 

 on the genital segments; the other three are inconspicuously 

 tinged with pink. The ovipositor valves of the females vary from 

 pale brown to pinkish yellow ; the female supra-anal plate is brown.

Type locality. — Douglas, Cochise County, Ariz. 



The male type, allotype, and two male paratypes were taken at 

 the type locality by W. W. Jones, September 10, 1944. Other para- 

 types taken at Douglas by Mr. Jones include one male and two 

 females, October 22, 1944 ; one female, October 23, 1932 ; one fe- 

 male, August 20, 1933 ; one male, September 20, 1924 ; one male, 

 October 10, 1943; one male (no date). Two paratypic males are 

 from Don Luis, Cochise County Ariz., September 24, 1922 (Rehn
