The American Entomological Society holds regular membership meetings on the fourth Wednesday in October, November, February, March, and April. The November, February and April meetings are held at the Academy of Natural Sciences in Philadelphia, Pa. The October and March meetings are held at the Department of Entomology, University of Delaware, Newark, Delaware. Society Members who reside outside the local eastern Pennsylvania, southern New Jersey, and Delaware area are urged to attend society meetings whenever they may be in the vicinity. Guests always are cordially invited and welcomed. Officers for 1995-1996: President: Joseph K. Sheldon; Vice-President: Jon K. Gelhaus; Recording Secretary: Dale F.

Boyd, 232 Oak Shade Road, Tabernacle Twp., Vincentown, New Jersey 08088, U.S.A. Manuscripts will be considered from any authors, but papers from members of the American Entomological Society are given priority. It is suggested that all prospective authors join the society. All manuscripts should follow the format recom- mended in the AIBS Style Manual for Biological Journals and should follow the style used in recent issues of ENTOMOLOGICAL NEWS. Three doublespaced, typed copies of each manuscript are needed on 8'/2 x 11 paper. The receipt of all papers will be acknowledged and, if accepted, they will be published as soon as possible. Articles longer than eight printed pages may be published in two or more installments, unless the author is willing to pay the entire costs of a sufficient number of additional pages in any one issue to enable such an article to appear without division. Editorial Policy: Manuscripts on taxonomy, systematics, morphology, physiology, ecology, behavior and similar aspects of insect life and related terrestrial arthropods are appropriate for submission to ENTOMOLOGICAL NEWS. Papers on applied, economic and regulatory entomology and on toxicology and related subjects will be considered only if they also make a major contribution in one of the aforementioned fields.

Vol. 106, No. 1, January & February, 1995 COPROPHILUS STRIATULUS (COLEOPTERA: STAPHYLINIDAE): CONFIRMATION OF ESTABLISHMENT OF A PALEARCTIC OXYTELINE ROVE BEETLE IN NORTH AMERICA 1 2 E. Richard Hoebeke ABSTRACT: Confirmation of the establishment of Coprophilus striatulus, a common and wide- spread Palearctic oxyteline staphylinid, in eastern North America (New York, Quebec, Ontario) is documented. Known North American distributional data are recorded and mapped. Recognition features are described and illustrated, and habitat preferences and native distribution are summa- rized. In early spring 1987, a single specimen of a rather large and striking species of oxyteline Staphylinidae was collected while sweeping streamside vegetation in a local state park in the Finger Lakes region of central New York. Since then, several additional specimens from other localities in the eastern United States and eastern Canada have also been examined (see "Spec- imens Examined" below). Using a key to the world genera of Oxytelinae by Herman (1970), these specimens easily trace to the genus Coprophilus Latreille. In North America, there are currently 2 recognized species, C. sexu- alis Leech which occurs in the Pacific Northwest, and C. castoris Campbell described from beaver lodges in eastern Canada (Campbell, 1979). The above- mentioned specimens represented neither. A close examination of the Euro- pean literature (Reitter, 1909; Portevin, 1929; Joy, 1932; Lohse, 1964), and use of a key to the American species of Coprophilus by Campbell ( 1979) enabled me to identify the specimens as C. striatulus (F. ), a widespread Palearctic species. Coprophilus striatulus was included in Campbell's (1979) key "only because it has been recorded from North America in the litera- ture" (see Fauvel, 1878). So far as known, the locality data listed below and 1 first of this in mapped (Map ) represent the confirmed records species North America. Specimens Examined. CANADA: Ontario: Ottawa, 23-IV-1984, A.
