Kermes cockerelli

Just recently Mr. E. O. Essig sent me Kermes galliformis Riley and Kermes cockerelli Ehrh. collected by Mr. E. J. Branigan on Cache Creek near Yolo, Yolo County, California, May 16, 1910, on California black oak, Quercus kelloggii Newli. Here they were associated together on the same host plant. Kermes cockerelli Ehrh. is of a light brown color and strongly gibbose.
