GRASSHOPPERS OF THE CONALCAEA COMPLEX— GURNEY 279 



Genotype — Conalcaea miguelitana Scudder, by desi^n^ation of 

 Scudder, 1897 (December). 



Of the other two original species of Conalcaea described by 

 Scudder (1897), 7ieomexicana is a synonym of Barytettix hum- 

 phreysii (Thomas), and truncativennis is currently being referred 

 elsewhere by Dr. Roberts, who finds it is not congeneric with 

 miguelitana. 



KEY TO THE SPECIES AND SUBSPECIES OF CONALCAEA 



1. Male eercus wider in apical third than at base (fig. 60, 6-0 ; posterior 



extensions of dorsal valves of aedeagus conspicuous in posterior view 

 (fig. 59, c, f, h, i, pe) (northern Sonora to western New Mexico and 



northern Arizona) —. ._ - 2 



Male eercus usually slightly narrower in apical third than at base (fig. 60, 

 o) ; no such extensions of dorsal valves of aedeagus as above (fig. 59, 

 a, b) (central Mexico) miguelitana Scudder 



2. Male eercus very strongly lobate, the dorsal margin stiongly emarginate 



(fig. 60, e, /) ; supra-anal plate wider at base than long (fig. 63, h) ; 

 dorsal valve of aedeagus elongate in lateral view, anterior margin little 

 produced and that broadly so (fig. 59, /) (central Arizona). 



eantralli, new species 



Male eercus either not lobate or much less so than above, the dorsal margin 



little emarginate (fig. 60, b-d, g-l) ; supra-anal plate scarcely wider than 



long, usually much narrower; dorsal valve of aedeagus shorter than 



above, anterior margin either abruptly or broadly produced (fig. 59, d, g) .

3. Male eercus so enlarged in apical third as to appear almost lobate (fig. 60, 



b-d) (north-central Arizona)-. huachucana coyoterae Hebard 



Male eercus variable, not nearly so lobate as above (fig. 60, t-0 (southern 

 Arizona, southwestern New Mexico, probably northern Sonora).

Male. — General form as in plate 10, figure 2; eercus (fig. 60, a) 

 slender, apical third usually slightly wider than base ; supra-anal 

 plate (fig. 63, i) longer than basal width, with conspicuous and 

 decidedly elevated lateral prominences and sharply rounded fur- 

 cula ; dorsal valves of aedeagus shorter than in other species, the 

 posterior extensions well developed (fig. 59, a) but not conspicu- 

 ous in posterior view (fig. 59, 6) ; ventral valves of aedeagus
