G O R H A M, F.Z.S., F.E.S. [Received November 29, 1887.] (Plate LIII.) The expedition made by Mr. G.Lewis to Japan in 1880 and !881 was the cause of a large number of additions to the Coleopterous fauna of those islands. The Endomychidae are a small hut very interesting family, and the new species now described show how very incomplete our knowledge of some of these minor groups are, and what interesting forms we may expect to see when other islands on the limits of the great continents have been equally well explored. Mr. Lewis's stay was, from circumstances, necessarily brief in many of the localities visited ; hence it is but reasonable to believe that a longer stay would have brought to light many new species, especially in such genera as Cyanauges, Stenotarsus, Chondria, and allied forms, which live a more or less obscure life, and only remain in the imago state for a few weeks. Compared with the number of species that are new, the number of new genera is large. This is sure to be the case in a fauna as yet only partially known, and lying so isolated from the centres whence most of the material which has been the basis of the systems proposed has hitherto come. Ectomychus and Chondria are not only new as genera, but hardly find a place in the subfamilies as vet proposed. The following is a complete list of Japanese Endomychidae : - Ancylopus melanocephalus, Ol. Danae orientalis, Gorh. Lycoperdina dux, Gorh. sp. - - castaneipennis, Gorh. mandarinea, Gerst. Saula japonica, Gorh. Rhabduchus denticornis, Gorh. Mycetina amabilis, Gorh. ancoriger, Gorh. laticollis, n. sp. Stenotarsus chrysomelinus, n. sp. internexus, n. sp. 'musculus, n. sp. nigriclavis, Gorh. Ectomychus, n. gen. Ectomychus basalis, n. sp. Bolbomorphus, n. gen. gibbosus, n. sp. Panamomus lewisi, Gorh. deeoratus, n. sp. brevieornis, n. sp, Phaeomychus, n. gen. rufipennis, Mots. Cyanauges gorhami, Lewis. plagiatus, n. sp. quadra, n. sp. nigropiceus, n. sp. Chondria, n. gen. lutea, n. sp. Symbiotes niponensis, Gorh. ? orbicularis, n. sp. |
