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

Callirhytis mamillaformis, new species

Host.--Quercus alba

Gall.--A bud gall half protruding beyond the bud scales, produced in the fall and probably dropping to the ground when mature. Somewhat globular with a nipple at apex, green or brownish, smooth, truncate at base when detached without circlet of white hairs.

Habitat.--IL, VA, DC

The type specimens were from galls collected at Ravinia, IL., from terminal buds on vigorous sprouts from stumps, October 22, 1916, and four living flies cut from the galls November 16, 1917, would probably have emerged in the spring of 1918. The galls have also been seen at Bluemont, Va., and Washington, D. C. A similar gall has been observed on Q. stellata at Poplar Bluff, Mo.; Hoxie, Ark.; and College Station, Tex., but not yet reared.

A similar gall has been observed on Q stellata in MO, AR, TX but not yet reared
