Callirhytis intersita, new species

Host: Quercus alba L.

Gall: Unknown. These were taken ovipositing in the internodes of the green new growth of white oak twigs on April 25, 29, and May 5. What gall resulted, if any, is not known. There are cells in the pith of white oak twigs, but fragments of the only dead adults cut out so far are different from these.

Habitat: The type is selected from adults taken ovipositing at Vienna, Va., on Apr. 29, 1945. Paratypes are from East Falls Church, Va., Apr. 25, 1941, and May 5, 1946.
