Callirhytis glomerosa, new species
Host: Quercus coccinea
Gall: A smooth greenish or brownish (in sun) bud gall in September or October around 3 mm in diameter, over half of it projecting beyond the bud scales, dropping when full-grown and then slightly pubescent at the base. Adults emerge the second spring.
Habitat: The type is from a gall collected at East Falls Church, Va., in late September 1933 and the adult cut out Oct. 16, 1934. Paratypes are from Vienna and Alexandria, Va. Similar galls have been seen on northern red oak, Spanish oak, and on Quercus ilicifolia Wangenh.
