weeks more or less, after the buds have unfolded. In 1920 
this was March 23 at Three Rivers; larvse were small but 
matured soon after collecting on March 3 at Zelzah, March 
10 at Gilroy, March 16 at San Luis Obispo, and March 21 at 
Coalinga. The Stanford records show Fullaway’s material 
to have emerged in April. Of 828 insects of which I have 
kept records, only 247, or 30 per cent, are males. If the 
sexes are never more nearly equal in numbers, fertilization 
may not always occur, and reproduction may be accomplished 
agamically at times. It is probably only a month or so before 
the galls of the next generation, varians, appear.

FEMALE. — Differs from the bisexual female of the variety only 
as follows: Basal segments of the antennas largely brown with little 
yellow; thorax not at all shrivelling on drying; abdomen relatively 
larger, thicker especially dorsally, extending dorsally as far as ventrally, 
or slightly produced either dorsally or ventrally; legs largely piceous 
black, the joints and all the tarsi brownish yellow; areolet large to 
moderate sized; length 1. 0-2.0 mm, 
GALL. — A slight swelling of the affected part, the larval cells with 
a distinct but inseparable lining; galls of two types as follows: 
Stem Galls: Short, blunt, irregular swellings; up to 35. mm. in 
length, and 12. mm. in diameter; very rough, covered with bark of 
normal color, also involving distorted buds, petioles, or leaves; some- 
times not producing much of any swelling. Internally filled with closely 
compacted, oval larval cells, located mostly toward the periphery (figs. 
51,55). 
Acorn Galls: Single larval cells buried in the wood of the acorn 
cup. The cell oval, averaging 1.5 by 2.2 mm.; with moderately thin 
v>^alls. Buried wholly or in part in the wood of the acorn cup, oftenest 
at the base; part of the cell sometimes visible within the cup, only 
rarely producing a slight swelling on the outside (fig. 57). 
RANGE. — As given for form pacificus. 
TYPES. — Of varians: Over 200 females and 49 clusters of galls.
