Dactylosphaera foreatum, n. sp.
Gall No. 9

Hosts: Carya amara [cordiformis]

On the same leaves containing the small galls, Nos. 7 and 8, I observed a number of larger ones with a dimpled depression above (which may be caused by the collapse of the thin paper-like centre), an opening beneath by a rounded, downy orifice, and having a diameter of .06 — .33 inch, and a vertical depth of .12 — .16 inch; all contained the female and her eggs, and some larvae.

On June 20th the winged imagos were very plenty, but no eggs could be found.
