the places were densely wooded with just a few open clearings. The nocturnal collectings with lamp were carried out on the terrace of the Hotel Myohyang as it was placed near a forest of relatively rich vegetation. An interesting and rich material was obtained, though mostly only the fauna of the lower zones was represented. In cases of nocturnal collectings - here and at all other localities - 160 W mixed light lamp and 80 W black-light lamp were used independently of each other. On Mt, Kumgang-san we collected only at sites also visited by the previous expeditions, their detailed descriptions were published in the earlier Reports (cf. References). We could collect only in water and with light except for one occasion of netting because of the extremely poor weather, out of the 4 days spent here it was raining incessantly two and half days, our pitfall traps were washed away, etc. Collecting with lamp was, however, quite effective. The surroundings of Kaesong consisting of mostly limestone and marmorous rocks are bordered by ricefields, fenwoods and bogs. The monsoon had not arrived until our departure from Kaesong, so the otherwise rich vegetation was dry; flowering plants - similarly to all other regions we visited - were found almost exclusively in parks. As we had opportunity to collect with lamp only In the town, our material yielded almost only species of the fauna of parks and ricefields around the town. During our stay in Haeju we could not collect in the obviously rich forests in the higher zone of Mt. Suyong-san because of the lack of time. Beating, netting and singling were made at the lower zones in Pinus plantations and in brushwoods renewed on clearings

. At the same time - differently from the manner usually employed - lamping could be made beside a waterfall in Mt. Suyong-san, with relatively good success. Aquatic collectings also were carried out at the above-mentioned localities. These collectings were aimed at first of all to obtain the microfauna, microcrustaceans and aquatic insects (Coleoptera, Heteroptera). For collecting microcrustaceans, a planktonnet of about 20 cm opening, made of artificial bolting silk with the mesh size of 60 u was used. The collectings were made mostly from the bank or by invading into the water as far as the wading boots allowed it, but sometimes a boat was also at our disposal. Water insects were collected with the aid of a waternet. Beetles inhabiting mud along the edge of water were collected by stamping on the mud and by flooding the mud with water. During our trip we collected both from standing and flowing waters. There are very few natural lakes in Korea, out of the localities we sampled Lake Sijung-ho and Lake Samil-po can be included here. Both of them have relatively greater surface and depth, and are located near the sea. Samples were taken from the open water with boat. The majority of the aquatic localities comprised small water bodies, the greater part of these was in artificial pools (small ponds have been sampled several times in city parks, puddles and pools beside the hotels). Some samples were taken from slowly flowing streams, canals, from parts of rivers separated from the main current. We have taken some samples also from wells and springs. Among the expeditions of the Hungarian Natural History Museum in Korea, ours was the second one which visited Mt. Myohyang-san. Based on our present knowledge we think that the data of the Seventh Expedition (FORRŐ and TOPÁL, 1981) are in part erroneous (because of the difficulties of transcribing the Korean locality names into Latin spelling), therefore it is necessary here to make some corrections. Nos. 637-683 on Mt. Myohyang-san are correctly placed in the North Pyongan Province. These mountains lay at the border of three provinces, therefore, it was rather difficult to recognize our collecting sites. Nos. 639, 649 and 661 are localities at the River Hyangsan-chon. The buddhist cloister of No. 638 is named Bohyongsa. The sites of Nos. 657-661 are in the region of Sangwon-am, and Nos. 664-672 in Manpoktong. Acknowledgements are due to the Hungarian Academy of Sciences and to the Korean Academy of Sciences of helping and organizing our tour. We should like to express our sincere gratitude to our Korean escort Dr. HOANG SUN RIN and to our German language interpreter Dr. KIM HOA SUN who helped us in every respect during our stay in Korea and also took part in the collecting work.
