Kinsey: Gall Wasp Genus Cynips 
237 
foveae that are more or less distinctly separated, each fovea broadly 
oval in shape; dorsal projections of the hypopygial spine very long; the 
cubital cell usually with, sometimes without such spots; length 3.7 to 
5.0 mm., usually nearer 4.5 mm. 
GALL. — Large, spherical, spotted, thin-shelled leaf galls with dense, 
silky, radiating fibers. Up to 33.0 mm., averaging nearer 20.0 mm. in 
diameter, symmetrical, normally spherical except where drawn out a 
bit at the attachment; very finely pubescent when young, largely 
smooth and naked when old, only microscopically shagreened, greenish 
or with a reddish tinge when young, brownish yellow or more russet 
when old, more or less closely set with small, reddish-purple spots. 
Rather thin-shelled, the larval cell central, supported by numerous, fine, 
silky, radiating, branched fibers, the cell large, broadly oval, up to 5.0 
mm. in length. Attached to the larger veins, singly or near each 
other, on the under surfaces of leaves of Quercus garryana. Figure 197. 
RANGE. — Probably found wherever Q. garryana or any of its 
forms occur, from British Columbia into northern California and fur- 
ther south along the Sierras. Figure 34.
