PROC. ENT. SOO. "WASH. VOL. 58, NO. 3, JUNE, 1956 153 BIOLOGICAL AND TAXONOMIC NOTES ON THE WASPS OF LOST RIVER STATE PARK, WEST VIRGINIA, WITH ADDITIONS TO THE FAUNAL LIST (Hymbnoptera, Acxtleata) By Kari, V. Krombein, Eiitomoloffy Besearch Bra/nch, V. S. Department of Agriculture, Washington, Z>. C. The wasp fauna of Lost River State Park, Hardy County, West Virginia, has been discussed in two jDrevious papers. The first paper (Krombein, Proc. Ent. See. Wash. 54: 175-184, 1952) presented an annotated list of 78 species collected June 18-25 and July 18, 1951. The second paper (Krombein, Bull. Brooklyn Ent. Soc. 49: 1-7, 1954) recorded 79 species collected June 29-July 5, 1953, of which 24 species had not been obtained in 1951. In 1955 we were again able to spend part of our family vacation in the Park, from July 4 to 11. The collections made during this period included 81 species of wasps, of which 26 are new to the Lost River list, thus bringing the total known from the Park to 128 species. Collection data are presented below for the 26 species new to the list, and the opportunity is also taken to add a few biological notes, and descriptions of Epyris deficiens, n. sp., Chalcogonatopus harpax, n. sp., and of the putative male of Ammoplanus unami Pate.
