The specimens treated here are collected in our collecting trip under the Korea-Japan Co-operative Science Program on "The Evolution and Biogeography of the Insects in the East Asia" in 1991 and 1992. Four new subspecies, Dacne (Dacrze) fungorum nigrocephala, Aporotritoma arakii fuscocephala, Aporotritoma tzigrovariegata intersecta and Tetratriplm itzornata nigrocephala will be described from the mainland of Korea, and 8 species are newly recorded from the country.

Until recent time only one endomychid species, Lycoperdina mandurinea Gerstacker 'was recorded by G. S. Lafer in 1992 from Korea. Following two species are newly added to the Korean fauna of Endomychidae. One is Cymbachus k0reanu.s sp. nov. and the other is Endomychus nigropiceus (Gorham) SO far known from Japan. EUMORPHINAE 1. Cymbachus koreanus sp. nov.Black to dark umber colored, pronotum very weakly and elytra rather strongly convex, antennae and tibiae slender, long. Elytra each with four yellow small markings, two of them subbasal and another two subapical in position.Head nearly flat, very weakly convex above sockets of antennae, very sparsely punctate, every puncture with short, fine and depressed hair, clypeal suture not grooved but very feebly ridged, clypeus trapezoidally produced, gently convex medially, apical margin rounded. Eyes rather large,

First part of the revision of the family Erotylidae from New Guinea and her adjacent islands treats the subfamily Triplacinae and part of the tribe Dacnini of the subfamily Dacninae.

(A.) circumcinctus sp. nov. A. (A.) moelzsicus sp. nov. A. (A.) biakensis sp. nov. A. (Olacauchilus) mir@sciatus subgen. et sp. nov. A. (Caulaochilus) subgen. nov. A. (Ulacaochilus) montivagw subgen. et sp. nov. A. (Laucaochilus) gressitti subgen. et sp. nov. A. (L.) brevistriatus sp. nov. A. (L.) angustistriatus sp. nov. A. (L.) tenuistriatus sp. nov. A. (A.) papuanus Csiki = A. astrolabicus Heller, 1918, syn. nov. Tritomophasma (Ttitomorpha) papuanum subgen. et sp. nov. Phoxogenys jucunda (Mader) comb. nov. = Spondotriplax jucunda Mader, 1936. P. solomonensis sp. nov.

Two species of Trogositidae, five species of Tenebrionidae and five species of Aheculidae are newly added to the Korean coleopterous fauna. TROCOSITIDAE Leperininae ,.
