Pronotum medially bare, sides pubescent, punctate with low parallel 
ridges near hind margin. Mesoscutum very finely coriaceous, uni- 
formly but sparsely pubescent from scattered punctures, parapsidal 
grooves percurrent, smooth, deep, broader behind, no median; pits of 
scutellum deep, smooth, separated by a distinct septum, disk rugose, 
richly pubescent. Cariae of propodeum bowed outward below, par- 
allel above. Mesopleura smooth, polished and bare above, pubescent 
below. Wing pubescent, ciliate, veins brown, first abscissa of radius 
faintly angled, areolet reaching one-fifth way to basal. ‘Tarsal claws 
with a tooth. Abdomen as long as head plus thorax, length to height 
to width as 37:29:28; lengths of tergites along dorsal curvature as 
21:6:3:1, a few hairs on VII, usual pubescent patches on sides of II, 
exposed parts of others bare, smooth. Ventral spine slender, in side 
view 10 times as long as broad, as long as hind metatarsus; ventral 
valves projecting obliquely upward. With the width of the head used 
as a base, the length of mesonotum ratio is 1.8; antenna 2.3; wing 3.75;

Types.—U.S.N.M. No. 563883: Type and 10 paratypes. Paratypes 
in the California Academy of Sciences and the American and Chicago 
Museums of Natural History. 
Host.—Quercus garryana. 
Gall (pl. 1, fig. 2) —A smooth, globular, green axillary bud gall, 
4-5 mm. in diameter, with a very slight nipple at apex early in spring 
as new leaves are developing. When detached showing a small whit- 
ish sunken scar. After drepping the thin outer fleshy layer becomes 
wrinkled and soon weathers away, leaving a smooth, slightly elon- 
gated, light tan cell whose wall is 0.6-0.7 mm. thick, not brittle, con- 
taining about 15 smali longitudinal passages. 
Habitat—Galls were collected on May 23, 1922, at Fort Jones, Calif., 
and sent to Washington under Hopkins U. S. No. 156407. The nutri- 
tive layer was then used up and the larvae full grown. Adults 
emerged on April 27, 1923, April 21, 1924, and April 3, 1925. These 
galls were seen on this host at Yreka and Scott Bar, Calif., and at 
Siskiyou, Oreg. Similar galls were seen on Quercus dumosa at Lake- 
port, Bartlett Springs, and Ukiah, Calif.

Agamic female—Light brown; ocellar area, front, and a transverse 
band on each tergite darker. Face granulate, front coriaceous; head 
from above transverse, cheeks slightly broadened behind eyes, occiput
