Just recently Mr. E. 0. Essig sent me Kermes (jalliformi.s 

 Eiley and Kermes cockerelli Elirli. collected by Mr. E. J. Brani- 

 2:an on Cache Creek near Yolo, Yolo County, California, May Kl, 

 1910, on California lilack oak, Quercus kelloggii Newb. Here

 to Kermes arizonensis King, fonnd in Arizona.
