Rh spines found in other varieties; mature galls light yellowish in color, only occasionally tinged pink, with a puberulence which only occasionally looks purplish, weathered galls turning dark brown and then black; internally not as hard as in other varieties; on Quercus durata and Q. dumosa. Figures 151-153, 193.

RANGE.—California: 7 miles southeast of Kelseyville (galls, Hildebrand in Kinsey coll.). Seigler Springs (Hildebrand in Kinsey coll.). Kelseyville (Schulthess, types). 6 miles west of Highland Springs, Scott Valley in Lake County, and the northeast side of Bartlett Mt. in Lake County (Schulthess in Kinsey coll.). Middletown and Clear Lake (galls, F. A. Leach in Kinsey coll.). Howell Mt. in northwestern Napa County (H. W. Clark in Kinsey coll.). Winters (galls, Vansell in Univ. of Calif, and Kinsey coll.).

Probably confined to an area including Lake County and parts of the adjacent counties. Figure 26.

TYPES.—9 females and 66 galls. Holotype female, paratype females, and galls in the Kinsey collection. Paratype females and galls in the American Museum of Natural History, the U.S. National Museum, and Stanford University. Labelled Kelseyville, California; galls September 20, 1925, and September 26, 1926; Q. durata; P. Schulthess collector.

Four years ago Mr. F. A. Leach collected galls of this variety, but I failed to breed insects from them. During the past three years Miss Pauline Schulthess, of Kelseyville, has secured fine collections of the galls from which insects have emerged. Miss Schulthess has done a splendid piece of work in collecting the galls of Lake County, an area that has been practically neglected heretofore as far as Cynipidae are concerned, altho it is biologically distinct from either the Great Valley or the Coast Ranges of California. I take pleasure in recording the fact that a young student's eyes and energy may contribute much to taxonomic science. Many other Lake County records based on the same collector's material will be found elsewhere in this study, often in connection with varieties and species which have not been previously described.

Galls collected by Miss Dorothy Hildebrand, near Kelseyville on July 26 (1927) were young and for the most part small, altho a few of them were of full size. Galls collected on September 1, (1927) and September 2 (in 1925) were full size and the larvae were not small. Bartlett Mountain material collected October 31 (1926) emerged out-of-doors at Bloomington, Indiana, on January 7 (1927). The Kelseyville material had not yet emerged on January 12 (1926), but on
