Andricus perfoveatus, new species

Galls (Pl. XXIV, Fig. 8). —Small, fleshy-walled capsules imbedded in the leaf-blade. Monothalamous. Spherical or more elongate, about 6. mm. in diameter (perhaps larger when fresh), leaf-green, drying brown, projecting about symmetrically from either surface of the leaf. The walls are thick, succulent, the cavity (in shriveled galls) about oval, 2. X 3. mm., with a distinct larval cell lining, but the cell inseparable (at least in the shriveled gall). On the very young leaves of Quercus kelloggii.

Range: —California: Santa Rosa and Redding.

At the time the galls were collected they were very fresh and succulent, on the very young, unfolding leaves of the black oaks, but inasmuch as adults emerged from some of these galls, in spite of their immediate shriveling on collecting, it would appear that the insects complete their development in a very short period in the early spring. Such species of cynipids are usually bisexual, so the male may yet be discovered for this species.
