( 58 ) III. Notes on various Central American Coleoptera, with descriptions of new genera and species. By George Charles Champion, F.Z.S. [Read November 20th, 1912.] Plates III, IV. This paper is mainly devoted to the enumeration and de-scription of the Coleoptera rejected by the various contri-butors to the " Biologia Centrah-Americana " as not belong-ing to the particular groups studied by them,^ or which have been overlooked in the sorting of the large collections that have passed through the hands of the Editors of that work during the past thirty-five years. The material has been supplemented by a number of interesting Mexican, Guatemalan, and Antillean forms recently sent for determination by the authorities of the U.S. National Museum, who have kindly allowed me to retain co-types of the new species for the British Museum. To determine these insects a few closely allied Antillean and South American forms have also had to be studied, and these, too, are dealt with in the following pages. The Coleoptera examined belong to the Clavicorn or Serricorn series, with the exception of the Psephenidae, Tenebrionidae, and Othniidae. The described Central American Lytopeplus (= Brachylon, Gorh.), Hapalips, Trichodesma, Petalium (= Micranobium, Gorh.), Eupactus (= Lioolius, Gorh.), Priotoma {=Eutylistus, Fall), etc., have all had to be re-examined, and a revised table of the species of each of these genera (Petalium excepted) is appended. The section Coleoptera of the " Biologia " was completed in Dec. 1911, eighteen volumes in all having been required for the enumeration of 18,039 species. This article, therefore, is practically a supplement to one of the divisions of the " Insecta " of that work, and the names of the species not occurring in Central America are, for convenience of reference, placed within square brackets. The additions to the fauna, 106, are marked (except in the preliminary hst) with an asterisk, 89 of them being described as new. ^ The Tenebrionid Rhipidandri were dealt with by Dr. Sharp in "B. C-Am.," Coleoptera, II, 1, pp. 690-692 (March, 1905), TRANS. ENT. SOC. LOND. 1913. — PART I. (JUNE)
