Neuroterus quercicola variety pacificus bisexual form pacificus

GALL. — Typical for the species, varying as to its location on leaf veins, petioles, young stems, or flower stems, this location apparently determined by the species of the host, as follows:

Q. lobata Gall: Elongate swelling mainly of the flower stem, beset with dwarfed clusters of stamens; involving the young twig, petioles, and leaf blades to a minor degree; elongate, but very irregular, up to 15. mm. in length by 8. mm. in diameter, greenish or yellow when fresh, drying light yellowish brown and shrivelling considerably upon aging (fig. 63).

RANGE. — California: Cupertino, San Jose (Fullaway); Stanford University, Sunol (McCracken) ; Metz (in coll. Univ. Calif.) ; Mt. Diablo (F. A. Leach coll.); Zelzah, Gilroy (Redwood School), Coalinga (Al-calde), Three Rivers, Exeter, Paso Robles, San Luis Obispo, Byron, Galt, Redding. Certainly thruout Central California and possibly wherever Q. Douglasii and Q. lobata occur.

Neuroterus pacificus sp. nov.

Neuroterus batatus [partial synonym for galls in California on Quercus lobata]

The species described by David T. Fullaway as Neuroterus batatus Fitch from California on Quercus lobata is not this species and I propose for it the name Neuroterus pacificus. Dr. Isabel McCracken kindly sent me some of Fullaway's material as well as some collected by herself and Miss Dorothy B. Egbert. The galls occur on Quercus lobata, Q. kelloggi and Q. douglasi. The species is double brooded and the early summer galls are on the under sides of the leaves and the late summer galls are hard, woody swellings on the terminal twigs, containing numerous long, oval larval cells imbedded in the soft spongy interior of the gall.
