the variety represented in the mountains farther north; variety patelloides is common in the southern Sierras and their extension as far south as the San Jacinto range; variety insolens is known only from the San Jacinto range but may extend southward into Lower California. Galls representing apparently undescribed varieties or indeterminate material of this same species are at hand or recorded from the following localities:
Oregon: Canyonville (acc. Weld 1926).
California: Baird, Scott Bar, Shasta, Ukiah, Calistoga, Mt. Diablo, El Portal, Redwood Park, Los Gatos, and San Bernardino Mts. (acc. Weld 1926). 6 miles west of Highland Springs, the northeast side of Bartlett Mt. in Lake County, and Cobb Mt. (P. Schulthess in Kinsey coll.). Elk Mt. in Lake County (Schulthess and Hildebrand in Kinsey coll.). Colfax (F. A. Leach in Kinsey coll.). Murphy (J. Laminman in Kinsey coll.). Placerville and Dunsmuir (Kinsey coll.). Yosemite Valley and north of Beaumont (W. Ebeling in Kinsey coll.).
Arizona: Santa Catalina Mts. (on Q. Wilcoxii, acc. Weld 1926).
In addition then to the three described varieties, there may be a distinct variety in southern Oregon and northern California, one in the northern Sierras, perhaps another in the central Sierras, and one in the San Bernardino Mountains. I have seen an insect of Weld's collection from this last named area, and it certainly represents an undescribed variety (fig. 169).
Weld has treated our present varieties as species of Acraspis. The hypopygial spines are close to those of Acraspis, but if allowances are made for the shortened wings of guadaloupensis, the rest of the insect characters are good for Antron, and the galls of guadaloupensis, which Weld did point out "are of a different type from those of the eastern species" of Acraspis, are in structure typical for Antron. Indeed, the galls of variety patelloides of the present species are strikingly similar to those of Cynips echinus schulthessae, the type of the subgenus.
The insects of the three described varieties of the present species seem distinguishable on nothing but minor color variations, by the shorter wings of variety guadaloupensis, by the aciculations found on the abdomen of patelloides, and by the naked and shining spot on the mesopleuron of insolens. The galls of these three varieties are, on the other hand, abun-
