JOURNAL OF ENTOMOLOGY AND ZOOLOGY 207 Just recently Mr. E. 0. Essig sent me Kermes (/alliformisRiley and Kermes cockerelli Elirh. collected by Mr. E. J. Brani-,i2:an on Cache Creek near Yolo, Yolo County, California, May lO,1910, on California black oak, Qnercus kelloggii Newb. Herethey were associated together on the same host plant. Kermescockerelli Ehrh. is of a light brown color and strongly gibbose. In some of the markings Kermes occidentalis is nearest alliedto Kermes arisonensis King, found in Figure L a, Kermes occidentalis n. sp.; b, Kermes cockerelli Ehrh.; c, Kermes(/alliformis Riley. (Photo by E. O. Essig). A COCCID FOUND ON THE SYCAMORE H. J. RYAN A number of the genus Pse/adococcus were found underthe bark of a sycamore within the limits of Claremont, Cali-fornia. Only one tree was found to have these insectson it althougli there were several in the cluster. Theinsects were associated with ants which seemed to be guardingthem. In general appearance the species appears like P. citri,differing, however, in having less prominent lateral api^endages,callouses on the lateral margins of the segment bearing two shortspines, and with circumanal spines of the same length as thoseof the anal lobes. As nearly as has been determined by com-parison with the descriptions given for P. qnercus, the specimens 208 - JOURNAL OF ENTOMOLOGY AND ZOOLOGY resemble this species. The host plant of P. quercus is given asthe canyon live oak, Quercus chrysolep
