482 PROCEEDINGS OP THE ACADEMY OF [Oct., 



quite mature, taken at 6,000 to 6,500 feet elevation in Strawberry 

 Valley, San Jacinto Mountains, July 17, by F. Grinnell, Jr., have also 

 been examined. The Arroyo Seco specimen was beaten from low 

 bushes. 



Clinopleura minuta Caudell, 



At Raymond, on September 3, this species was found swarming, 

 invariably on the ground, especially in a stubble field. The insects 

 jumped farther than any species of North American Orthoptera taken 

 by us, but owing to their tremendous numbers a large series was 

 easily secured. A series of fourteen males and thirty-one females 

 was taken at this locality, a single female also being secured at Summit 

 House the same date in a situation similar to that frequented at Ray- 

 mond. The series contains several females winch slightly exceed 

 Caudell's maximum measurements for the caudal femur and ovipositor. 

 There is considerable variation in the general shade of coloration in 

 the series, some individuals being decidedly more testaceous than 

 others, the usual dark area on the lateral lobes of the pronotum being 

 hardly or only partially indicated in some of the pale specimens. 

 The previous records of the species were from Ahwahnee, Calaveras 

 and Raymond, California. 



GRYLLID^i. 

 Ellipes minuta (Scudder). 



A single individual of this species was taken along the nearly dry 

 bed of the Mohave River at Cottonwood, September 9. Although 

 considerable beating was done but one specimen was found. 



The species has been taken at Palm Springs, San Bernardino and 

 Ahwahnee, California. 



Ectatoderus occidentalis (Scudder) ? 



A single male individual of this genus was taken at Cottonwood, 

 September 9. We have assigned it provisionally to this species, 

 originally described from damaged female specimens taken at Cape 

 San Lucas, Lower California. The original description of Scudder's 

 species is so brief and the sex differences of many species of this genus 

 so great, that in the absence of females the determination is not at 

 all positive. No relationship exists with E. borealis Scudder, known 

 from California and New Mexico, the produced pronotum of the 

 Cottonwood male suggesting that of Liphoplus mexicanus Saussure, 22 

 but the tegmina are much shorter, rather different in character and the 

 facial scutellum is not distinctly divided.
