Allokermes rattani

Allokermes galliformis

Kermes cockerelli

Kermes occidentalis, n. sp.

Host--Oak, Quercus sp.

Female Scale — Globular in outline; 5 mm. in diameter; of a dull gray color. Segmentation indicated by five transverse narrow blackish bands, which are broken at intervals by somewhat larger round black dots. Surface between the bands of a marbled light gray-brown. The entire surface is dull, not shiny, and is covered with very minute black specks seen only under a hand lens. The above species was received from Mr. E. M. Ehrhorn in 1901 taken on Quercus sp. in California and labeled Kermes galliformis Riley. The latter species is very different, the color being pale yellow; appears minutely and evenly speckled with brown under a hand lens and is more or less confused or mottled with gray or brown. 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. In some of the markings Kermes occidentalis is nearest allied to Kermes arizonensis King, found in Arizona.
