196 Indiana University Studies 
collection. Labelled Oroville, California; galls April 1, 1920; Q. Doug- 
lasii; Kinsey collector. 
The present re-descriptions are new studies of the holotype and the 
paratypes in the American Museum and Kinsey collections. 
My material collected at Three Rivers on March 23 and at 
Oroville on April 1 (both in 1920) had just appeared with the 
young oak leaves, but the adult insects emerged from these 
galls within a few days. The eggs, laid in the veins of the 
young leaves of the blue oak, apparently do not hatch for a 
couple of months. In early July, the galls of the agamic form, 
echinus , begin to appear. 
The bisexual form of variety vicina is so close to ribes that 
the two should be carefully compared in making determina- 
tions in this group.

Cynips echinus var. C Kinsey, 1927, Field and Lab. Manual in Biol.: 
104. 
FEMALE. — Very dark rufous and black, the entire body including 
the legs and antennae often black; foveal groove usually smooth at the 
bottom, with a very fine ridge dividing it indistinctly; clouded patch 
distinct in the cubital cell, but the patches in the discoidal cell very 
faint or wholly lacking; length 1.7 to 2.8 mm., averaging nearer 2.2 
mm., distinctly smaller than the variety echinus. Figure 177. 
GALL. — Indistinguishable from that of variety echinus, unless aver- 
aging a bit smaller. Quite regularly spherical, entirely covered with 
from 20 to 60 spiny projections, these broadest when they are fewest 
in number; mature galls bright to dark coral red or coral red with a 
violet bloom, not as often puberulent as in variety echinus; on Quercus 
Doug lasii. 
RANGE. — California: 7 miles south of Kelseyville (Hildebrand in 
Kinsey coll.). Kelseyville (Schulthess, types). 5 miles north of Upper 
Lake (Schulthess and Hildebrand in Kinsey coll.). Scott Mountain in 
Lake County, Cobb Mountain in Lake County, and northeast and south- 
ern sides of Bartlett Mountain in Lake County (Schulthess in Kinsey 
coll.). Inskip (Leach in Kinsey coll.). Sierran foothills east of Dinuba 
(L. H. Powell in Kinsey coll.). 
Apparently occurring over an area extending from Lake County 
in a narrow fringe about the Great Valley of California. Figure 25. 
TYPES. — 17 females, many galls. Holotype and paratype females 
and galls in the Kinsey collection. Paratype females and galls in the
