Vol. 51, pp. 1-6 February 18, 1938 PROCEEDINGS CXHK BIOLOGICAL SOCIETY OF WASHINGTON — BUTTERFLIES FROM VIRGINIA AND THE DISTRICT OF COLUMBIA. BY AUSTIN H. and LEILA F. CLARK. Since the publication of our " Preliminary List of the Butter-flies of Virginia" (Proc. Biol. Soc. Washington, vol. 50, pp. 87-92, June 22, 1937) Professor Ellison A. Smyth, Jr., and Mr. Carl W. Gottschalk of Salem have been so very kind as to send us records of three additional species from Roanoke and Mont-gomery Counties, we ourselves have taken two new to the fauna of the State, and a species recently described by Dr. William T. M. Forbes proves to be common and widely dis-tributed throughout the region. Furthermore, during the past year a number of records of more than usual interest have been given us by several of our friends, or have come to our notice during the course of our personal investigations. It has seemed advisable to list the additions to the fauna of Virginia and the more interesting records in order to bring up to date the list of species known from the State and to call attention to extensions of known ranges or casual occurrences of the more localized or rarer forms. The following six species and subspecies are herein for the first time recorded from Virginia: Neonympha areolatus areolatus, Phoebis philea, Erynnis baptisiae, Hesperia attalus, Polites mystic, and Atrytone bimacula. The addition of these six raises the total number of species and subspecies definitely known from Virginia to 139. Two species are added to the fauna of the District of Columbia; these are : Papilio palamedes and Erynnis bapiisiae. Of these the first is merely a casual or accidental visitor, and the second has heretofore been confused with E. persius. To the Maryland list we add Erynnis baptisiae. 1— Proc. Biol. Soc.
