individuals they are scarcely visible. Some specimens have 

 heavy dotting on a very pale ground, in others the dotting 

 is heavy on a dark ground 5 many show faint dots on a light 

 ground j and several have few dots on a dark ground. A 

 yellowish line usually runs back on the neck from the outer 

 edge of each occipital plate. Two similar lines may some- 

 times be seen above these. The lower parts are creamy 

 white, sometimes clouded with brown toward the sides. 

 The young average much darker than the adults. 



Distribution. Originally collected somewhere near Fort 

 Tejon in the Canada de las Uvas (probably on the Mohave 

 Desert), in Kern County, it has since been found in other 

 parts of the same county at Mohave, at an altitude of 3,200 

 feet in Kelso Creek Valley near Weldon, and at an altitude 

 of 4,900 feet in Freeman Canyon, Walker Pass. The most 

 northern Californian record is the east slope of the Inyo 

 Mountains, Inyo County. In Los Angeles County it has 

 been secured in Antelope Valley, at Pine Creek, Neenach, 

 and Pallett. San Bernardino County records are Hesperia, 

 Victorville, Providence Mountains near Bonanza King mine, 

 Goffs, 30 miles southeast of Daggett, and New York Moun- 

 tains, six miles southeast from Purdy. I found it near 

 Cabazon, Riverside County. Specimens from San Felipe 

 and La Puerta valleys, in San Diego County, are in the col- 

 lection of the University of California.
