Field notes on gall-inhabiting cynipid wasps with descriptions of new species

ZOPHEROTERAS SPHAERULA, new species

Host. — Quercus maxima [rubra], red oak.

Gall. — Spherical or slightly ellipsoidal, not depressed, found in fall on both upper and lower surface of leaf attached to a vein, singly or 3-4 in a row, about 3 mm. in diameter, greenish or yellowish-green often tinged with red above, dropping to the ground before the leaves. Monothalamous, fleshy, apparently solid when fresh, the larval cavity scarcely visible.

Habitat, — Type locality, Evanston, IL. The galls were also seen at Wilmette, Ravinia, and Moline, IL.; Medina, N. Y. ; and at Bluemont, Va.

Biology. — Galls collected on ground under two large forest trees on the bank of the Chicago River four miles west of Evanston on October 8, 1916, contained pupae when examined September 17, 1917, and adults November 16, 1917, which emerged in numbers and were found alive in out-of-door breeding cage on March 13, 1918, others emerging before April 6.
