Collecting at Catalina was much like that among the low hills 

 along the coast and not nearly as good as among the San Gabriel 

 foothills. 



Cottonwood, San Bernardino County, California. Altitude, 2,274 

 feet; September 9. On the desert clothed with greasewood and other 

 plants of the Mohavan region collecting was very productive, especially 

 at dusk when a number of interesting things were taken. The desert 

 is here more or less rolling and the spot is ideal for collecting in a dry 

 region. Nearby along the border of the Mohave River, in tall weeds 

 and grassy ground vhich had been inundated but was at the time 

 parched, a number of interesting species were found. On the train at 

 night species of Homceogamia and Stagmomantis were taken, two of 

 which are new. On the whole, this was the most interesting desert 

 situation in which collecting was done during this trip. 



Kelso, San Bernardino County, California. Altitude, 2,118 feet; 

 August 12. In this the most extremely arid desert area encountered, 

 covered only with a scattered growth of greasewood and a very few 

 low desert plants, quite a few specimens were taken. North from the 

 station, among the volcanic foothills of the North Range of the 

 Providence Mountains, a very few specimens were captured, but these 

 were the most interesting captures made at this point. Pcecilotettix 

 sanguineus was seen but not taken. Kelso is situated seven miles 

 from the huge shifting sand hills called the Devil's Playground, and near 

 it is a dry soda lake. A visit to that area would doubtless have 

 proved interesting, but time was not available. 



Cima, San Bernardino County, California. Altitude, 4,192 feet; 

 August 12. Cima is situated on a high plateau covered with tall 

 tree yuccas. The low vegetation was scant and consisted of a very few 

 greasewood bushes and other species of desert shrubs. In some nearby 

 low hills covered with essentially the same vegetation long search 

 failed to disclose any species of special interest. In a growth of 

 tumble-weed beside the railroad all the specimens of Ageneotettix 

 australis and Cordillacris apache were taken. 



Lyons, San Bernardino County, California. Altitude, 2,850 feet; 

 August 11. In an area of loose sand with scattered tufts of dry 

 grass Heliastus minimus alone was found. The desert here was covered 

 with fragments of volcanic rock, among which greasewood and a very 

 few other desert plants grew and the entire country had a decidedly 

 baked appearance. In this area a number of very valuable captures 

 were made, although it was insufferably hot, much more so than 

 at Yuma.
