Andricus texanus sp. nov.

Gall.--In clusters, closely packed together, on the under side of the leaves of post oak (Quercus minor [stellata]). Monothalamous. Hard, woody, subcylindrical, wedge-shaped or subtriangular, sometimes more or less flattened, pointed basally at the place of attachment to the leaf. Each individual gall is densely covered with short, coarse, whitish, wool-like fibers. They are closely packed together on the leaf and have the appearance of being one large gall, but each gall may be readily separated and detached. When old the fibers turn brown and the galls drop to the ground.
