dantly distinct, furnishing another case of the value of physi- 
ologic data. 
Our reasons for treating these insects as varieties of one 
species, rather than three distinct species, are the very nearly 
identical characters of the insects, their common hosts, and 
the fundamentally common plan of the galls. While these 
galls are so different in form, they are not as diverse as the 
galls of the several varieties of Cynips echinus , and the 
younger or more stunted galls of patelloides are quite like 
those of variety guadaloupensis.

Mus. 68 (10) : 59. 
FEMALE. — Head rufous and black; the mesopleuron almost en- 
tirely punctate and hairy; the abdomen smooth, naked, and without 
aciculations on segments three to six; the wings much reduced, about 
0.62 of the body in length, falling distinctly short of the tip of the 
abdomen; length 2.5 mm. Figures 168, 185. 
GALL. — Much flattened, circular, disk-like, up to 7.0 mm. in diam- 
eter and 1.2 mm. in height; the walls thick and the larval cell the only 
internal cavity; on. leaves of Quercus chrysolepis. Figure 146. 
RANGE. — California: Guadaloupe (R. W. Patterson; types). 
Santa Lucia Mts. (gall, acc. Weld 1926). 
Probably occurring thruout the range of Q. chrysolepis in a more 
southern Coast Range area of California; perhaps extending thruout the 
mountains of California from the Sierra Madre north to the Oregon 
boundary. Figure 27. 
TYPES. — Holotype and one paratype female and a gall at Stan- 
ford University. From Guadaloupe, California; galls December, 1906; 
adults January, 1907; Q. chrysolepis; R. W. Patterson collector. 
The present re-descriptions are based on my recent studies of all 
the type material. 
PARASITE. — Eurytoma querci Fullaway (acc. Fullaway 1912).
