Disholcaspis corallina

Pale yellowish, globular galls, about 12 mm. in diameter, found on the twigs of Quercus douglasii. The galls are pointed at the poles and the surface is roughened by irregular ridges, or bears short, blunt tubercles giving it the appearance of coral.

Habitat. Mt. Diabalo, California. 

Disholcaspis eldoradensis

Small, brown, cushion-shaped galls, sessile on twigs of Quercus kelloggii and Quercus lobata, hard and woody with the base broadly inserted in a slit in the bark. The top is flat and much pitted. Length about 4 mm., breadth about 3 mm., height about 3mm.

Hosts:
Quercus lobata
Quercus berberidifolia
Quercus durata
Quercus garryana

Andricus brunneus, n. sp.

Gall:
Thin-shelled, subglobular galls on leaves of Quercus douglasii, about the size of a pea, pointed at opposite poles.

Andricus kingi

Small, pink, cone-shaped galls on the underside of leaves of Quercus lobata, about 5mm. high and 4 mm. across the base, which is broad and rather saucer-shaped. The outer portion of the gall is conical, the sides curved inwards slightly. The larval chamber is near the apex, where the exit hole is found. 


Andricus parmula

Very small, flat, reddish, disc-shaped galls on the under side of leaves of Quercus lobata, about 3 mm. in diameter, slightly elevated in the center. 

Andricus pattersonae (unisexual generation)

Thin, flat, disc-shaped galls from leaves (presumably) of Quercus douglasi, about 6 mm. in diameter, greenish gray with lilac center, the margin irregular; upper surface a trifle wrinkled but otherwise smooth.

Andricus wiltzae n. sp.

Polythalamous galls formed in the buds of Quercus lobata, distinguished by the thickly compacted cluster of aborted leaves.

Neuroterus saltatorius (unisexual generation)

Gall: Small, subglobular, 1.25-1.50 mm., pale reddish-brown, with a small nipple at either pole; slightly sculptured.

Callirhytis nigra n. sp.

 Gall. An irregular swelling or enlargement of the terminal twigs [apparently mistaken, see other sources] of Quercus lobata, subglobular, 15 mm. x 12 mm., apparently monothalamous.  

Diplolepis dubiosa n. sp.

Gall (PI. XXIII, tig. 1). A small, brown, thin-shelled gall arising, several together, in the staminate ament of Quercus agrifolia. The gall is about 3 or 4 mms. long, rather angulate and more or less clavate. Polythalamous.

Neuroterus quercus-batatus (Fitch)

Cynips quercus-batatus Fitch
Neuroterus batatus Mayr
Neuroterus quercus-batatus Dalla Torre & Kieffer

Gall. Early summer galls on under side of leaf of Quercus douglasi, a flat, irregular swelling, distorting the leaf, polythalamous, 8 mm by 5 mm, and a sordid brown color. Late summer galls, from which adult flies emerge the following spring, small hard woody swelling in terminal twigs of Q lobata, containing numerous long, oval larval cells imbedded in soft spongy interior of gall. 

Habitat. Stevens Creek, beyond Cupertino CA. San Jose, CA.
