The galls of this species are common and in places abun- 
dant in the fall in the Great Valley of California. They begin 
development in the mid-summer, soon maturing. The larvae 
become fully grown sometime later and transform into adults 
which emerge) in November or December, or in some cases 
not until after the middle of January. The old galls fall with 
the leaves or stay attached to the twigs for a while, but I 
found no remnants of the galls, except for a single specimen, 
in collecting in February and March in the range of this 
species. 
The Q. lobata and Q. Douglasii varieties of this species are 
easily distinguished by the insect characters, the surfaces, 
interior structures and attachments of the galls, and by the 
host relations. The two varieties which occur on Q. Douglasii 
are not to be distinguished by the gall characters, altho the 
insects are different enough. The two on Q. lobata have 
insects that are difficult to separate but galls so unique that 
they have previously been considered distinct species. The 
published records for the occurrence of any of these insects 
on more than one species of oak are based on mis-determina- 
tions, as noted under conspicua.

FEMALE. — Median groove practically lacking; scutellum anteriorly 
almost as smooth as the mesonotum; foveal groove indistinct, without a 
trace of division into foveae; wing veins and infuscations generally 
heavier and the spotting heavier than in conspicua, less heavy than in 
indicta; the discoidal cell with usually 6 to 10 spots; the cubital 
cell heavily spotted, the spots tending to coalesce; the radial cell with 
or without spots; length 2.7 to 3.7 mm., averaging smaller than either 
of the other varieties. Figure 217. 
GALL. — Indistinguishable from that of variety indicta, unless aver- 
aging larger. Green when young, becoming light and then dirty gray 
in color; appearing finely pubescent, in reality microscopically set with 
fine papillae and narrow, reticulated ridges, with only a scant pubescence 
of stellate and longer hairs, these wearing off in time; internally with
