GRASSHOPPERS OF THE CONALCAEA COMPLEX— GURNEY 301 



Canyon of the Baboquivari Mountains, it occurred on grassy- 

 benches along the sides of a canyon. In both the Santa Rita and 

 the Santa Catalina Mountains, humvhreysii has been found on 

 desert cotton (Gossijpium thurberi Todaro), but it is not pre- 

 cisely known to be a host plant.^^ 



' Adults examined were collected as early as the month of April 

 and as late as November 15 (both extremes in the Baboquivari 

 Mountains of Arizona), though most collections have been made 

 from July to late October.^* 



I Altitudes at which humvhreysii occurs have been recorded above 

 6,000 feet, but most records are from 3,000 to 5,000 feet, and it 

 appears that this is typically a species of lower altitudes than 

 those preferred by Conalcaea huachucana.

 Male. — General form as in plate 10, figure 1 ; cercus scarcely 

 curved mesally when seen from above, the apex broadly rounded, 

 ventral margin weakly curved, the ventroapical angle little pro- 

 duced (fig. 64, ; furcula about as in cochisei (fig. 64, m), the 

 lobes a little smaller and more abruptly demarked laterally ; supra- 

 anal plate shaped about as in Conalcaea miguelitana (fig. 63, i) , 

 the dorsolateral prominences varying from minute, as in the figure 

 of cochisei, to about twice the size of those illustrated in C. migu- 

 elitana; epiphallus much as in humphreysii (fig. 63, e), the apical 

 margin of lophi more roundly and evenly curved, the ancorae 

 somewhat larger; dorsal valves of aedeagus slender, narrowed 

 basally, divergent apically (fig. 64, h) . 



Coloration : General color varying from pale yellowish green to 

 dark olive-green. Antennae reddish orange, darker in apical 

 fourth; eyes russet; black pattern, edged with yellow, on lateral 

 lobes of pronotum; hind femur varying from solid green, with 

 darkened carinae and knees, to yellowish, with green on carinae 

 and dorsal half of pagina, dark area of knees usually brownish 

 purple; hind tibia purple, the spines and spurs black apically; 

 hind tarsus pale purple to brown ; supra-anal plate and cerci often 

 reddish brown.

'* Hebard (Ent. Newa, vol. 44, pp. 231-235, 1933) has noted a few winter and early spring Or- 

 thoptera in the vicinity of Tucson, Ariz., but does not mention Conalcaea or Barytettim.
