Habitat. — The type locality is Young, Ariz., where Mrs. N. W. Capron collected galls on an undetermined oak November 1, 1935. Four flies emerged on March 20, 15 more by March 24, and one more by April 3, 1937. Agreeing with these is an adult taken ovipositing on Quercus gambelii at Williams, Ariz., on April 11, 1918.
