GRASSHOPPERS OF THE CONALCAEA COMPLEX — GURNEY 281 



simple, without basal flaps; epiphallus as drawn (fig. 63, c), with 

 dorsal margin of lophi (L) oblique and broadly rounded, rather 

 than projecting and narrowly rounded as in the subspecies of 

 hiiachucana.^' 



Coloration : General color varying from pale brown to blackish 

 gray; dark bar of lateral lobes of pronotum weakly developed in 

 some specimens; longitudinal division of tegmen with respect to 

 color evident but not always clear, poorer defined than in other 

 species; hind femur lacks distinct longitudinal bar, partial one 

 sometimes present, ventral margin of paginal area usually black. 



Measurements (length in millimeters) of representative speci- 

 men : Body, 20 ; pronotum, 4.5 ; front femur, 4 ; hind femur, 12.5 ; 

 tegmen, 3.5. 



Female. — Differing from male only with respect to genital seg- 

 ments, and an increased robustness typical of the sex. 



Measurements (length in millimeters) of representative speci- 

 men : Body, 25.5 ; pronotum, 5.5 ; front femur, 4.5 ; hind femur, 

 14.5; tegmen, 4.1. 



The species superficially resembles h. huachucana, but the 

 dorsal swelling in the apical third of the male cercus is less, the 

 furcula and lateral prominences of the supra-anal plate are much 

 more developed, and the dorsal longitudinal stripe on the external 

 face of the hind femur is weak, in addition to different features 

 of the aedeagus. 



Type. — A male designated by Rehn and Hebard, 1912. Museum 

 of Comparative Zoology, Cambridge, Mass. 



Type locality. — Sierra de San Miguelito, San Luis Potosi, 

 Mexico. 



The lectotype and one male and two female lectoparatypes of 

 Scudder's series have been examined. The male is now deposited 

 in the U. S. National Museum (U.S.N.M. No. 58934). The only 

 other specimens examined were taken by H. R. Roberts at the fol- 

 lowing localities: 18 miles west of San Luis Potosi, San Luis 

 Potosi, Mexico, 7,500 feet, September 5, 1940 (1 <J ) ; between 

 Zacapu and Zamora, Michoacan, Mexico, 7,500 feet, September 6, 

 1938 (23 6,8 ? ) ; 5 miles south of Chilchota, on road to Urupan, 

 Michoacan, Mexico, 6,000 to 7,000 feet, August 15. 1940 (11 S, 

 7 9). 



The Arizona record of Bruner (1908) was probably based on 

 material of h. huachucana. His record of miguelitana from Ciu- 



" The ancorae, or anterior hooks of the epiphallus (A), appear different in figure 63, a, h, c, 

 awing to the directions in which they point, but I have been unable to find constant differences in 

 fundamental shape. The terminology of the male genitalia is larjroly Ihat of Roberts (Proc. Acad. 

 Nat. Sci. Philadelphia, vol. 93, pp. 201-246. 1941 ).
