Acraspis compressus n. sp.

Gall.--Small sub-globular bodies from 2 to 3 mm in diameter attached to the under side of the leaves of the red oak, Quercus rubra, in the fall, about the time the leaves are beginning to turn brown. The galls appear like wax, and are either pure white or tinged with red while on the leaves, and when cut into are fleshy and juicy like a potato. The galls fall to the ground with or a little before the leaves, and each develops a single larva which gets its growth in the fall but does not emerge until the following summer. Only a very thin shell of the gall is left after the fly emerges.
