color and markings, but distinctly gibbose. Treated with 
KOH the scale turns black, and after prolonged boiling it 
turns liquid black. Derm after boiling, by transmitted light, 
yellowish, no structural characters visible. 
Larve—Dark red-brown (lost in boiling in KOH), elongate-oval. 
This is a very pretty species. Its nearest ally is K. galliformis, 
from which it is separable by having a longitudinal constriction 
which is not pallid, and by being gibbose. It is also allied to 
K. cockerelli and K. gillettei in being gibbose. It was first col- 
lected by Mr. E. O. Essig in the Santa Paula Canyon in the 
mountains near Santa Paula, Ventura County, California, in 
1910. In August, 1913, Mr. S. A. Pease collected it in San 
Bernardino County. Through Mr. Essig and Prof. Cockerell 
this material was turned over to me. The species was described 
from the large number of females in these sendings. 
The host plant is the California coast live oak, Quercus 
agrifolia. 
I am pleased to name it after its first collector. 
THE EIGHTH CALIFORNIA KERMES 
= . . a 
Kermes occidentalis n. sp. 
GEO. B. KING 
Lawrence, Mass. 
Female Scale—Globular in outline; 5 mm. in diameter; of a dull 
gray color. Segmentation indicated by five transverse nar- 
row blackish bands, which are broken at intervals by some- 
what 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.
