The species has been recorded from a number of localities in southern 

 California. 



Sohistooeroa venusta Scudder. 



At Indio, on July 29, this species was very plentiful in tall weeds 

 along a watercourse, two males and three females being taken. A 

 female from an elevation of 3,000 feet in the San Gabriel Mountains, 

 taken October 9, 1908, by F. Grinnell, Jr., is also in hand. The pro- 

 notal stripe is narrower in the San Gabriel Mountains individual than 

 in the female from Indio, Avhile the specimens from the latter locality, 

 and to a lesser degree in the San Gabriel individual, are much paler 

 than Huachuca Mountains, Arizona, representatives. The species has 

 previously been recorded from Palm Springs, Indio, Tulare and Gazelle, 

 California, while specimens from San Diego and Cuyamaca, San Diego 

 County, are also before us. 



Sohistocerca shoshone (Thomas). 



Three males of this species were taken at Las Vegas, Nevada, August 

 10, where the species was found in clumps of green weeds near water. 

 The habits and habitat of this species seemed to be exactly the same 

 as those of Schistocerca venusta, but we have never found the two at 

 the same place. 



The only previous records of the species from Nevada are either 

 indefinite or from the northern section of the State (Truckee Valley). 



Hesperotettix festivus Scudder. 



At Indio this species was abundant on July 29, a series of eighteen 

 males and twenty-five females being taken. At Cottonwood, Sep- 

 tember 9, the species was found in small numbers on rabbit-weed, 

 two males and one female being taken, while a single female was secured 

 in the Arroyo Seco at Pasadena, August 1. At Las Vegas, Nevada, 

 August 10, a series of twelve males and seven females was secured. 



There is a striking amount of individual variation in size in both 

 sexes of the Indio series, but particularly in the female. Of the same 

 series, six males and six females are decidedly brownish in color or 

 show a marked tendency in that direction. Both Cottonwood males 

 are decidedly brownish, while the single female is green. All the green 

 individuals in the series have more or less distinct pinkish or pinkish- 

 red femoral annuli, the majority of the brown or brownish specimens 

 having these obsolete. The green of the Las Vegas series is pale and 

 decidedly yellowish, all from that locality being uniformly colored. 

 The Cottonwood female has a very faint bluish cast to the entire 

 tegmina. The median whitish cephalic and pronotal line is bordered 

 laterad with blackish or dark green in a number of specimens.
