Female (allotype) . — General form as in male, larger and more 

 robust ; differing as follows : Face less retreating ; eyes less glob- 

 ose ; vertex as in figure 63, g ; posterior emargination of pronotum 

 broader; tegmen proportionally rather broader (fig. 58, e) : geni- 

 talia essentially as in coyoterae. 



Coloration : Differing from male as follows : Face and lower 

 part of lateral lobes of pronotum Van Dyke brown ; abdomen and 

 ventral parts largely Roman sepia, terga darkened apically, a 

 mediolongitudinal pale band barely suggested; dark bar on pro- 

 notum less sharply defined; dark longitudinal band on left hind 

 femur occupying only anterior two-thirds of pagina. 



Measurements (length in millimeters) : Body, 30; pronotum, 

 6.5; front femur, 4.3; hind femur, 15.5; tegmen, 4.8. Greatest 

 width of pronotum, 7.3. 



There are five male paratypes, the pronotal length of which 

 varies from 4.7 to 5.5 mm. The cerci are slightly variable, those 

 of two specimens exhibiting more dorsal development of the apical 

 lobe (fig. 60, /) ; there is a tendency for the apical margin to be 

 irregular, but in some specimens it is smooth. The aedeagi of 

 two paratypes are preserved in glycerol, and the outline of the 

 dorsal valves in lateral view is less rounded anteriorly than in the 

 holotype. Especially in the dry aedeagi, the extent of the posterior 

 development of the dorsal valves is somewhat variable. The six 

 female paratypes show no significant size variation. Two have 

 more slender tegmina (fig. 58, /) than the allotype. The paratypes 

 vary but little in color, beyond exhibiting moderately variable 

 shades of brown on the dorsal surfaces. Two females have an 

 obsolete mediolongitudinal pale abdominal bar.

Type locality. — "General Springs," Coconino County, Ariz. 



The entire series of six males and seven females was taken at 

 the type locality. The male holotype and five paratypes (1 male, 

 4 females) were collected on August 28, 1935, by Irving J. Can- 

 trail, one female paratype by him on August 29, 1935. The allo- 

 type and five paratypes (4 males, 1 female) were collected August 

 28, 1935, by T. H. and Grace G. Hubbell. 



"General Springs," a fire cabin and lookout station on the Coco- 

 nino Plateau just at the edge of the Mogollon Rim, is about 12 

 miles northeast of Pine (Gila County) and about 10 miles east 

 of Baker Butte (Coconino County). All specimens of caritralH 

 were taken on the slopes below the rim, mainly along the lower
