Vol. 99 Washington : 1949 No. 3247NEW SPECIES AND RECORDS OF STAPHYLINID BEETLESFROM FORMOSA, JAPAN, AND SOUTH CHINABy ISIalcolm CameronA COLLECTION of 950 Specimens of beetles belonging to the familyStaphylinidae from Hainan Island, southeast China, Formosa, theLoochoo Islands, and Japan has been turned over to me for reportby Dr. R. E. Blackwelder, of the United States National Museum.These specimens were collected during several trips from 1932 to 1935by Dr. J. Linsley Gressitt, now of Lingnan University.Two new genera, 22 new species, 1 new variety, and many new recordsare included. Unless otherwise noted all specimens were collected byDr. Gressitt. Holotypes are in the United States National Museumexcept as noted ; paratypes of all new species are in my collection ; andparatypes of most of the new species are also in the Gressitt Collectionin the California Academy of Sciences. Dates are abbreviated, as, forexample, V-7-32=May 7, 1932.
1. EUPIESTUS CHINENSIS, new speciesShining; head and thorax black, elytra and abdomen pitchy, theposterior margins of the tergites rufescent. Antennae black, the firstfour segments reddish. Legs reddish yellow. Of the size of sculpti-colUs Kraatz but narrower, the interantennal fossae smaller, thoraxnarrower and less transverse. Head subtriangular, with two largefossae anteriorly and one at the middle of the base, and at the innermargin of the eye with a sulcus; with small rather close punctureslarger than in sculpticolUs. Antennae as in sculpticolUs, the secondand third segments of equal length, the fourth to tenth transverse.Thorax very slightly broader than long, the sides in front practicallyparallel, posteriorly strongly arcuately constricted, with eight fossaeas in sculpticolUs more coarsely punctured than in that species. Elytra818874?49 1 455
