Zoological Collectings by the Hungarian Natural History Museum in Korea 51. A Report on the Collecting of the Sixth Expedition By H. STEINMANN and T. VÁSÁRHELYI (Received November 30, 1979) Abstract: A detailed report on the zoological collectings and main results of the sixth expedition in 1979 is presented. About 16 000 animals, mostly insects were taken in three regions of the Democratic People' s Republic of Korea. A list of collecting localities is given. It was planned at the beginning of the expeditions of the Hungarian Natural History Museum (cf. References) that experts would visit different parts of Korea in different periods. Our expedition began work on the 10th of September and finished it on the 30th of September, thereby partly covering the period of the fifth expedition. The localities were with one exception those visited already by previous expeditions. The collectings resulted in about 16 000 specimens. The materials worthy of mention are those belonging to the special field of interest of the authors (Neuropteroidea, Dermaptera, and Hemiptera, respectively). We reached Pyongyang by a direct flight from Moscow on the 10th of September. During our stay in Korea we were provided with à car enabling us to coUect near Pyongyang also on such days partly occupied by cultural programmes. Our escort KIM DAE-KON and our German interpreter Ing. DZO SUNG-UN organized our collecting programme for which we would like to express our most sincere thanks. We collected mostly in the 50 km surroundings of the capital but spent one night in Songhwa and six nights in Mt. Kumgang-san (Diamond Mountains). 41 hours were spent with collecting in daytime and 46. 5 hours in night with lamping (about 16% of our time there). We left Pyongyang on the 2nd of October for Budapest, again via Moscow. In our first days we enjoyed a warm dry weather but later we had some cold rainy days, too. The first nights were also warm but from the second week on we could hardly collect with lamp. According to our colleagues rain is extraordinary in this season. The only place visited for the first time by Hungarian zoologists was Songhwa. There were apple plantations around the town, and on the way we could see kilometres of plantations grey of an insecticide. The low dry hills around the hotel were grown in by secondary vegetation mostly by Robinia, and by an undergrowth poor in plant species. The soil was stony on the hills. In the valleys there were fruit trees and in spite of this it proved to be one of the best collecting localities for us. A small brook is in one of the valleys against the Hotel and this source of water is enough to feed a small marshy meadow with sedge covering also the hillsides. This was one of the best lamping place as well. In Pyongyang we used the bulb on the hotel terrace looking over a well lighted street, however, we had some good flights, especiaUy one on the 20th of September when about 1 500 insect were captured. It was at the be-
