PROC. ENTOMOL. SOC. WASH. 79(4), 1977, pp. 599-604 NEW RECORDS OF CADDISFLIES (TRICHOPTERA) FOR OHIO Eric P. McElravy, Thomas L. Arsuffi, and Benjamin A. Foote Abstract. — Collections of adult Trichoptera were made along several streams in northeastern Ohio between 1970 and 1976. Sixty-nine of the collected species apparently represent new records for Ohio. An annotated list of the newly recorded species is presented and it nearly doubles the number of caddisflies reported from Ohio. The order Trichoptera has been little studied in Ohio. Marshall's (1939) work on the caddisflies of western Lake Erie is apparently the only study dealing exclusively with the occurrence of species of the order in the state. Most of the other records for the state are given in Ross' (1944) work on the Illinois fauna. A few additional records are contained in Horwath's (1964) study of the insects of Gibraltar Island (western Lake Erie), Gordon's (1974) revision of Cheiimatopsyche, and Ross' (1966) descriptions of new Oecetis species. As a result of these earlier published studies, 77 Trichoptera spe-cies were known to occur in Ohio. Forty-nine of these species are from Lake Erie. In addition, two more species of Hydropsyche are listed for the state by G. Schuster and D. Etnier, University of Tennessee, in their study of the immatures of that genus (personal communication). Resh (1975) reported 175 species from Kentucky; presumably a similar number will be recorded from Ohio. Since 1970, and especially between 1974 and 1976, collections of Tri-choptera have been made at four stream sites in northeastern Ohio (Fig. 1). Sixty-nine of the species apparently are the first reported records for the state. Complete lists are forthcoming for the collections from northeastern Ohio. Description of Study Areas Stehhins Gulch. — Stebbins Gulch, located within the Holden Arboretum in western Geauga County, is a deep gorge cut in sandstone and con-glomerate. The stream that flows through this gorge, a tributar)' of the East Branch of the Chagrin River, has a high gradient and good water quality. Collections were made by sweeping during 1970, 1971, and 1972 (Tkac' 1973). CuyaJiofia River. — The Cuyahoga River in Portage and Geauga Counties is a moderately-sized stream of x'arying sulxstrate and current. Collections of Trichoptera were made in 1975 with a gasoline hmtern by J. Wilke, De-
