American gallflies of the family Cynipidae producing subterranean galls on oak

Compsodryoxenus illinoisensis, new species

Host. — Quercus macrocarpa Michaux.

Gall. — Cells in the thickened bark at the crown of small sapling causing an abrupt swelling of four to five times the normal diameter of the shoot and extending for a distance of as far as 30 cm., or in bark at base of young shoots in such numbers as to cause a noticeable swelling. Almost wholly buried under the debris on forest floor. Resembles the gall of the sexual generation of Callirytis futilis (Osten Sacken) on roots of large trees of Quercus alba, except that cells are smaller.

Type locality. — Winnetka, Illinois. One gall was found October 22, 1914, and contained living adults. Another was found November 1, with adults emerging, and they continued to come out until November 11. Another gall was found at Fort Sheridan, Illinois, on October 3, 1914, and living flies were cut out of it on October 29.
