Rh forms on the blue oak at Kelseyville. Incepta and vicina also agree in being darker than the other insects of the species, and in having foveal grooves which are distinctly smooth at bottom.

''Cynips echinus var. A'' Kinsey, 1927, Field and Lab. Manual in Biol.: 104.

FEMALE.—Head, thorax, and legs entirely bright, brownish rufous, the antennae dark brown terminally and lighter basally; foveal groove weakly and sparingly sculptured at the bottom, rather distinctly divided by a very fine ridge; abdomen bright, reddish rufous, only darker rufous in places; the cloud in the cubital cell light, the patches in the discoidal cell even lighter; in length about 2.7 mm., averaging smaller than echinus or douglasii. Figure 179.

GALL.—Irregularly cushion-shaped, spheroidal, more or less flattened in places, the base more or less constricted, the apical end more or less widened and flattened, bearing a few, very short and blunt projections mostly on the rim at the top of the gall; mature galls light but dull, brick-red in color, the surface dull and often partly violet because of a puberulence; on Quercus dumosa and Q. turbinella. Figures 147-149.

RANGE.—California: Paso Robles, Pasadena, and Upland (Kinsey coll.). El Toro, Sorrento, Fallbrook, and Alpine (galls, Kinsey coll.). Jacumba (Q. turbinella, A. E. Stanley in Kinsey coll.).

Probably thruout more southern California wherever Q. dumosa and the closely related scrub oaks occur, from San Diego County to Palo Alto, except in the San Bernardino range. Figure 26.

TYPES.—19 females, 18 galls. Holotype and paratype females and galls in the Kinsey collection. Paratype females and galls in the American Museum of Natural History, the Museum of Comparative Zoology, and the U.S. National Museum. Labelled Upland, California; February 3, 1920; Q. dumosa; Kinsey collector. Collected in San Antonio Canyon on the side of the San Antonio Mountains.

While never as abundant as varieties echinus and douglasii of more central California, this species is not rare in Southern California wherever the scrub oaks, Q. dumosa and related species, grow. All of our records give Q. dumosa as the host, except the Jacumba material which is from Q. turbinella, an oak that is hardly more than a variety of
