Type locality.--Kinsey described this species from an insect cut from a gall collected in San Diego County by D. Cleveland. It is a common gall on the foothills of the Stanford environs, Santa Clara County, California. Galls of this species in the Stanford collection are mahogany-red on exposed side, bright yellow on shaded side, covered with golden-yellow very slightly raised spots, subspherical with apex drawn to a point, 6 to 8 mm. in diameter when mature. Monothalamous. This is a very conspicuous gall, growing in the axils of leaves. The old galls are persistent, turning brown on weathering. It is very abundant on both dumosa and durata.
