lough range, on the Nevada side of the California boundary line, a 

 specimen of this very rare species was flushed from a greasewood 

 bush. It flew up in a way reminding one of the swift flight of a Schisto- 

 cerca and did not alight for at least two hundred yards, when it 

 perched on the top of another greasewood bush. The specimen was 

 captured and proved to be the first known female of the genus. When 

 compared with the male type of the species the Nevada specimen 

 does not appear to be separable, such differences as do exist, as larger 

 size and slightly different proportionate width of the fastigium, being 

 easily attributable to sexual differences. The ovipositor curves 

 distinctly but not at all decidedly ventrad, the apex being acute and 

 the margins not spined. The measurements are as follows: 



Length of body (exclusive of ovipositor), 25.5 mm. 



Length of pronotum, 7.2 



Width of pronotum (caudad), 4.5 



Length of tegmen, 47 



Greatest width of tegmen, 7 



Length of caudal femur, 28 



Length of ovipositor, 25 . 8

The coloration is much paler than in the type, although the pattern 

 is essentially the same, all the paler spots and markings on the prono- 

 tum and tegmina being ivory white and the remainder of the surface 

 pale yellowish buff, becoming yellowish on the distal portions of the 

 femora and on the tibiae, the darker portions of the tegmina being 

 brownish-clay color becoming paler distad. The line pattern on the 

 pronotum is essentially the same as and more distinct than in the type, 

 while no green is present on the specimen. 



The type locality and only previously published record of the species 

 is Florence, Arizona. 



Eremopedes gracilis (Rehn). 



An adult pair of this form was taken at Cottonwood, September 9, 

 frequenting low growth, where they were much protected by their 

 coloration. The tegmina of the male, projecting two and one-half 

 millimeters beyond the pronotum, are considerably convex with the 

 internal margin of the apex obliquely arcuate, the external margin 

 straight with the apex rounded subtruncate, the tympanum being 

 almost entirely hidden. The ovipositor of the female is slightly 

 shorter than the length of the caudal femora, while the tegmina are 

 minute pads, well hidden under the pronotum. 



The terminal dorsad abdominal segment of the male is deeply and
