New American Cynipids from galls

Callirhytis florensis, new species

Host. — Quercus marilandica

Gall (pl. 1, fig. 1). — Scattered about among the stamens in a shortened catkin ; conical, slightly curved, blunt at apex, 2.2 mm. long by 1.0 mm. in diameter, of same color as the anthers but with longitudinal purple streaks, the surface sparsely covered with tangled hairs. Exit hole 0.6 mm. in diameter near apex.

Habitat. — The type material was collected at East Falls Church, Va., from a Q. marilandlca on May 10, 1931. Adults of both sexes emerged May 18 to 25, the largest number coming out on May 20. In the fall of 1932 nearly every acorn on this tree had a gall of Callirhytis balanaspis Weld, and the galls gathered on the ground in October produced adults that emerged on April 9, 1934.
