Andricus stramineus, new species.

A tan-colored, bare, smooth, ellipsoidal gall, bursting out of the bark along the internodes of small twigs, drawn out to a blunt point at apex, 2 by 3 mm. by 3mm. high, single or in small groups in fall. Contains a single larval cell with a wall 0.2 mm. thick.

Host.-Quercus oblongifolia.

Habitat.-Mrs. N.W. Capron collected galls containing pupae on February 4, 1935, at Nogales, Ariz. One adult was cut out of the gall on February 14 and three emerged on March 5. She collected galls also at Young, Ariz., on an undetermined oak. Galls have been seen at Patagonia, Ariz.
