The series examined in this connection embraces the following 

 localities: Kenworthy, San Jacinto Mountains, 5,000 feet elevation, 

 June 9, F. Grinnell, one female; Dos Palmos, Santa Rosa Mountains, 

 3,500 feet, May 26 to June 1, F. Grinnell, five females; Kelso, August 

 12, one male; Cima, August 12, two males; North Range, Providence 

 Mountains, August 12, four males, one female; foothills Bird Spring-

 three males, one female.
