 CALIFORNIA 



BY EDWARD P. VAN DUZEE 

 Curator, Department of Entomology 



Of the 39 species described in this paper 26 were taken dur- 

 ing my field work in southern California in May and June, 

 1917. The principal places visited were Coachella, a little 

 north of the Salton Sea, having a depression of 76 feet below 

 sea level ; Palm Springs at the northwestern edge of the desert 

 near the foot of the San Jacinto Mountains, with an elevation 

 of about 425 feet above sea level ; Soboba Springs in the San 

 Jacinto Mountains near the town of San Jacinto, with an eleva- 

 tion of about 2,000 feet : Keen Camp in the San Jacinto Moun- 

 tains at an elevation of 4,800 feet, with excursions on Mt. 

 Tahquitz to 8.000 feet, and Colton, in San Bernardino County, 

 with an elevation of about 800 feet. Unless otherwise stated, 

 all localities are in California and all specimens from Califor- 

 nia were taken by myself.
