208 distinct, furnishing another case of the value of physiologic 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.

Acraspis guadaloupensis Weld, 1926 (in small part), Proc. U.S. Nat. Mus. 68 (10):59.

FEMALE.—Head rufous and black; the mesopleuron almost entirely 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 diameter 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 Stanford 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).
