Andricus robustus, new species

Host.--Quercus stellata

Gall (fig. 18). — A midrib cluster on under side of leaf in fall, the galls dropping to the ground when mature. The individual galls are somewhat globular, tapering to a pedicel at base and pointed with a slight scar at apex, greenish and mottled with white when fresh, turning brown during winter on ground. This is the gall described in connection with the fly of Cynips vacciniformiis Beutenmueller which seems to have come from an accidentally included gall of a different sort in the breeding cage.

Habitat. — The type material was collected at Arlington, Texas, November 3, 1917, when the galls were still dropping to the ground. On December 1, 1919, living flies (that would probably have emerged in spring of 1920) were cut from the galls. Some of the same lot of fresh galls were sent to William Beutenmueller, who reared adults January 10, February 14, 15, 20, 21, 1919, and more in February, 1920. Paratype flies were cut out December 1, 1919, from galls collected at Texarkana, Ark., in October, 1917. The galls have been collected also at Webster Groves, Poplar Bluff, and Ironton, Mo.; Hoxie, Little Rock, and Hot Springs, Ark.; Palestine, Cuero, and Austin, Tex. ; Cottondale, Fla.; Wasliington, D. C.; Falls Church, Va. Galls collected at Washington in late October, 1923, gave adults February 22, March 1, 14, 17, 1925, and these have been included among the paratypes.
