trasted, while the Mt. Lowe individuals have the bars and maculations 

 standing out in strong contrast. The femoral bars are limited to the 

 vicinity of the dorso-lateral carina in the El Toro specimens, more 

 extensive ventrad in the Pasadena individuals and covering the greater 

 portion of the lateral face of the femora in the Mt. Lowe representatives. 



At Pasadena the species was taken on the lower slopes of the San 

 Rafael Hills, among shrubs and dry grasses. On Mt. Lowe the insect 

 was found to be very shy, of swift but not long flight, and when pursued 

 closely the individuals would hide in the grasses, very effectually 

 concealing themselves. At El Toro the species was found common in 

 high grain growing along irrigating ditches. 



The species has previously been recorded from the following localities 

 in California: Los Angeles, Point Loma, Lancaster, Cahon Pass and 

 Gazelle. 



Opeia testacea Scudder. 



Eight males, two females and two immature individuals from Las 

 Vegas, taken August 10, are referred to this species. Here the species 

 occurred in a growth of desert plants and grasses on the plain sur- 

 rounding the town. 



The broad postocular bar is more or less strongly present on the 

 head and dorsal half of the lateral lobes of the pronotum in the majority 

 of the specimens, those without indications of the bar having the sides 

 of the head and the whole of the pronotal lobes entirely infuscated. 



The species has been recorded from the following Californian local- 

 ities : Lancaster, Kern City, Tulare. Lathrop and Dominguez. 



Cordillacris grinnelli n. sp.

Related to C. occipitalis, cinerea and affinis, but differing from all 

 in the shorter tegmina which leave a considerable portion of the 

 abdomen exposed. The coloration is nearer to that of affinis, as 

 represented by Idaho specimens, but the longitudinal line on the 

 lateral face of the caudal femora is more continuous than in that 

 species. 



Size medium (for the genus); form moderately slender. Head 

 but little expanding ventrad, with the dorsal length about subequal 

 to that of the dorsum of the pronotum, the occiput very slightly 

 arcuate and the fastigium horizontal when seen from the side; fas- 

 tigium slightly acute-angulate with the apex rotundato-truncate, the
