New species of gall-producing cecidomyidae

Cecidomyia nyssaecola sp. nov.

Gall. This is made by a narrow upward and inward fold of the margin of the leaf of sour gum (Nyssa sylvatica) and measures about .3 to 1 mm in diameter and from about 2.5 to 3.5 mm in length. Sometimes only a few of the folds occur on a leaf and again the entire margin on both sides of the leaf is covered with them, causing the leaf to become scalloped. The gall is pale yellowish or yellowish green and contrasts with the dark green leaf, making it a rather conspicuous object, readily detected. The galls are sometimes more or less contiguous when occurring in numbers on the same leaf. When dry the gall becomes brown.

Habitat: VA, KY, IL, NY, NJ, PA, NC

Very common everywhere in the vicinity of New York, from which locality my specimens were obtained. The gall may be found in June and the fly emerges in July.
