D. pacifica Boursin, 1943 - A single, rather fresh male specimen was collected in the stormy weather in Cheju. HADENINAE Dictyestra dissectus (Walker, 1865) - A half-dozen of freshly emerged specimens were observed during the night of the massive migration in Cheju. Mythimna separata (Walker, 1858) Leucania ?insecuta Walker, 1865 "CUCULLIINAE" sensu Hampson Meganephria (Belosticta) extensa (Butler, 1879) - The South Korean material consists of two significantly different forms occurring sympatrically, which show good distinctive features in the genitalia of both sexes. One of them is the well-known, light greyish "extensa" with strong dark stripe along the inner margin while the other species is darker, irrorated granulosely by dark brown and the stripe at inner margin is obsolescent. The typical "extensa" is found in various localities of the peninsula, the dark species is known only from the vicinity of Chuncheon (recorded as new for the fauna of Korea by Park & Weon 1988, under the name M. extensa). For the final taxonomic interpretation the study of the types of extensa and cinerea (Butler, 1881) are necessary. M. (B.)funesta Leech, 1889 M. (B.) debilis Warnecke, 1933 Eupsilia (Orbona) fragariae (Vieweg, 1790) E. quadrilinea (Leech, 1889) - The species was recorded firstly from Korea by Ronkay & Park (1993), a sole male specimens was collected by sugar bait in the Mts Paekun-san. Xylena formosa (Butler, 1878) Lithophane consocia grisea (Graeser, [1889] 1888) *L. pruinosa (Butler, 1878) - The first Korean specimens (two males, Nos 1642, 1665) had been collected by sugar baits. The species is relatively widespread along the Pacific Coast (Russian Far East, Japan, Manchuria). *L. ustulata (Butler, 1878) - The distribution of the species is similar to that of the preceding one, the nine specimens were all collected by sugar baits in the Paekun-san Mts; the species is new for the fauna of Korea. The specimens are unusually dark in coloration with less intensive markings, differing rather strongly from those of the Japanese and Far Eastern populations. L. venusta (Leech, 1889) - The species was recently recorded from Korea (Ronkay & Park 1993); a single male specimen was collected at light at the higher forest zone of Cheju. *L. nagaii Sugi, 1958 - The species was considered as endemic to Japan, its discovery in the southern edge of the Korean peninsula (Mts Paekun-san) is one of the most important results of the expedition. One of the two specimens came to the light, the second was found on the bait put on the trunk of an old alder tree. Jodia sericea (Butler, 1878)
