Bird Spring Mountains, McCullough Range, Lincoln County, 

 Nevada. Altitude, 2,900-3,000 feet; August 11. On the slopes up 

 to the foothills of these mountains the character of country and 

 vegetation was much the same as about Lyons, California, nearby, 

 except that the volcanic fragments were here much more abundant. 

 Tytthotyle maculata was found here also, and the single specimen of 

 Drymadusa arizonensis taken on this trip was found just where the 

 slopes reached the plain. 



Las Vegas, Lincoln County, Nevada. Altitude, 2,050 feet; August 

 9, 10. Most of the material from this locality was taken in the only 

 green place for many miles around, along the small stream which springs 

 out of the desert to the north of Las Vegas. A good series was also 

 captured on the surrounding desert, which differed from the usual 

 desert of the Southwest in that there was no greasewood and hardly 

 any mesquite to be found. In some spots this desert was excessively 

 parched and barren. Las Vegas, offering both desert and damp 

 land collecting, was more productive than the majority of places in this 

 character of country. 



El Toro, Orange County, California. August 20. Collecting was found 

 to be unproductive in the rolling grain fields about the village, which 

 were very dusty and warm at this season. 



Tia Juana, San Diego County, California. August 16. The low 

 hills, covered with scant vegetation, and a swampy section near the 

 Mexican boundary line were examined. 



Coronado Beach, San Diego County, California. August 14, 15 and 

 16. Salt marsh, strand and weed field situations were examined at 

 this locality and at South Coronado Beach. 



Raymond, Madera County, California. Altitude, 940 feet; Sep- 

 tember 3. In a hillside stubble field near the village Orthoptera was 

 found in quantities. The Decticid Clinopleura minuta was particu- 

 larly abundant. The town is not as far out in the valley as Merced, 

 and collecting between this place and Miami would without doubt 

 have proved extremely productive had more time been available. 



Merced, Merced County, California. Altitude, 173 feet; August 

 30. All of the Orthoptera captured at Merced were taken in a very 

 dry stubble field near the railroad station. 



Summit House, Madera County, California. Altitude, 2,200 feet; 

 September 3. In this vicinity specimens of interest were taken on 

 a hillside covered with a scattering growth of oaks. The undergrowth 

 here consisted of a thick mat of short dry yellow grasses interspersed 

 with very low tar weed.
