Andricus cryptus n. sp.

Gall--Small cocoon-like gall one-tenth of an inch in diameter, hidden in a branch under the bark and not visible externally. There is no appreciable swelling of the branch from this gall-fly, the fly escaping by cutting a hole from its larval cell through the bark; observing these holes in the bark led to its discovery.

Described from two specimens reared in May, 1886.
