forms on the blue oak at Kelsey ville. Incept a 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 flat- 
tened in places, the base more or less constricted, the apical end more 
or less widened and flattened, bearing a few, very short and blunt pro- 
jections mostly on the rim aL the top of the gall; mature galls light 
but dull, brick-red in color, the surface dull and often partly violet be- 
cause of a puberulence; on Quercus dumosa and Q. turbinella. Figures 
147-149. 
RANGE.— California: Paso Robles, Pasadena, and Upland (Kin- 
sey 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 Ameri- 
can 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 South- 
ern California wherever the scrub oaks, Q. dumosa and re- 
lated species, grow. All of our records give Q. dumosa as 
the host, except the Jacumba material which is from Q. tur- 
hinella, an oak that is hardly more than a variety of Q. du-
