Diplolepis laurifoliae

This globular leaf gall with a free-rolling cell was described from Quercus laurifolia from "Florida", the flies emerging in March. The types are labeled Jacksonville. The writer collected galls at Jacksonville on April 4 from which not all the adults had yet emerged. Galls were noted on Q. phellos at Richmond, Falls Church, Clarendon, and Alexandria, Va., and at Chesapeake Beach, Md. In Virginia the galls appear with the opening of the buds in spring and are about full grown by the middle of April when the leaves have reached about half their normal size. For rearing they should not be gathered until they contain pupae or adults. Falls Church galls gave adults May 8-15, 1920. Clarendon galls gave flies May 14—18, 1921. It is questionable whether this name should be maintained as distinct from palustris (Osten Sacken).
