FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXXI I. Zoological Collectings by the Hungarian Natural History Museum in Korea 28. A Report on the collecting of the Fourth Expedition By O. Gy. DEL Y and Á. DELY-DRASKOVÏTS (Kf c<*i v*"<l D^CPIIIIHT I. I'iTT) Abstract: A detailed report on the zoological collectings and main results of the fourth expedition in 1977 are presented. 34 342 invertebrates and 249 vertebrates were taken in three regions of the Democratic People's Republic of Korea. A list of collecting localities is given. Within the framework of a cultural interstate agreement between the Korean Academy of Sciences and the Hungarian Academy of Sciences it had again become possible - similarly to the previous three expeditions of 1970, 1971 and 1975 (MAHUNKA and STEIN MANN, 1971, PAPP and HORVATOVICH, 1972, PAPP and VOJNITS, 1976) - to continue the zoological collecting trips of the Hungarian Natural History Museum in the Democratic People's Republic of Korea. The aim of our mission was similar to the previous expeditions participated by 2 persons each. We had to further enrich the East-Asian materials of the Zoological Department of our Museum, on the one hand, and to help the exploration of the Korean fauna, on the otner. Our trip was planned for a month, from the middle of June 1977 to the middle of July. It was expected that this period would be favourable for collecting insects, especially flies (Á. DEL Y-DR AS KO VITS), but also for catching small vertebrates, mainly amphibians and reptiles (O, Gy. DELY). And in addition it would take place in a time when the earlier expeditions did not collect. On the 27th of June, 1977 we boarded an aeroplane in Budapest and touching MoscowOmsk- Irkutsk reached Pyongyan, the capital of the Democratic People's Republic of Korea on the next day. The main object, the programme, the investigations carried out and the allowed methods of collecting were the same as in the previous expeditions. Even our collecting localities coincided or were similar with those attended by the members of the former groups. Since the authors of the previous reports published not only their results but gave full description of the collecting localities and the vegetation, we decline of repeating them again. We have spent 28 days in Korea: 11 days were taken up by collecting (on 6 occasions we had the opportunity to use lamps). The remaining days were spent by cultural programmes and by inland travelling to the different collecting sites. From the 11 days of collecting 5 were spent in the environs of Pyongyan (De Sang-san, Nam-po, Tesson and Sa-Gam), 3 in the famous Diamond Mountains (=Kum-gang san) (Hotel Kum-gang near the village Ontsong, Rukbaam, Lake Sam II and around the waterfalls Mammulsan and Guriong) and the remaining 3 days in the mountain regions of Pektusan (hotel at the village Sam-zi-yan, Dehongdan, Musan
