Andricus toumeyi, new species

Host. — Quercus toumeyi.

Gall (Fig. 20). — A sessile, egg-shaped and somewhat one-sided stem swelling, representing a much shortened lateral branch which seldom continues beyond the gall, densely covered with small leaves. It measures up to 15 mm. long by 10 mm. in diameter, is covered with bark of normal thickness, its single rather small cell is placed somewhat radially without any false chamber and the exit hole is in one side.

Habitat. — Type material collected at Pataironia. Arizona, on December 12, 1921, when the galls contained pupae. The adults were cut out of the galls on January 1. One paratype was cut from a gall collected in the Chiricahua Mountains. Similar galls have been seen on Q. undulata on Abo Pass in the Sandia Mountains, near Socorro, in Nogal Canyon, and in Burro Mountains in New Mexico.
