Neuroterus papillosus sp. nov.
Gall. (Plate X, Fig. 2.) In numbers on the leaves of swamp white oak (Quercus platanoides [bicolor]) in June. Monothalamous. Elongate oval, blister-like bodies protruding on both sides of the leaf, and without a nipple on the under side. Length about 1 mm.; width about .75 mm.
Habitat. Bronx Park, New York City.
The gall is somewhat similar to that of N. niger, but is smaller, and lacks the nipple on the under side. The flies emerge during June and early in July, from galls produced in May. The species is undoubtedly double brooded.
