Dryophanta lanata, n. sp.

Galls. During late summer and autumn the galls of this species are found on the under side of leaves of Quercus rubra and Q coccinea, appearing externally as little bunches of compact brown wool and hardly distinguishable in outward appearance from the galls of Andricus flocci Walsh. The galls seldom occur singly, but usually in clusters of from four to eight. A cluster of eight galls when fully grown will measure about 3/8 of an inch in width by 5/8 of an inch in length. An individual gall when denuded of its covering is in the form of an irregularly shaped cone with a bulging base, the diameter of the base being three or four sixteenths of an inch, which is nearly twice the height.

The galls fall to the ground in the autumn in advance of the leaves, and the flies emerge the following summer. The galls are abundant at Ames, Iowa and I have taken a number in the vicinity of Champaign, IL.

Described from two bred females from galls taken at Ames, Iowa. Male unknown.
