Mountains) the Zanthoxylum schinifolium S. et Z. x was in inflorescence attracting large numbers of stinging wasps (digger wasps, common wasps, spider wasps, scolioid wasps and bees). Where it was possible we singled on the favourite Korean shrub, the well-known Althaea rosae L. that was floweing far and wide. Primarily we caught various species of Bombus on these flowers. By sweeping soft-stemmed plants and shrubs we secured many Ichneumonoidea. Here we should like to mention that the common grass-lands are quite unknown in Korea. Thus, sweeping was made almost exclusively over stretches of weeds along roads, or by cultivated lands, on waste lands, along the skirts of forests and, of course, in the forests. We obtained exceptionally good results by sweeping the shrubby undergrowth of a Larix-Betula woods in the vicinity of our hotel at Sam-zi-yan (Larix gmelini, L. potanini, Betula mandshurica) (No. 282). In the afternoon almost each sweeping between 4 and 6.30 p.m. we collected an average of 8-10-15 specimens of Ichneumonoid wasps (Ichneumonidae, Braconidae, Chalcidoidea, Proctotrupoidea). One "round" of sweeping in Korea meant about 100-120 sweeps and by this time quite a good quantity of animals have been caught to be economic for using an aspirator without losing many of the escaping specimens. At Sam-zi-yan one round of sweeping meant about 50 sweeps since this was sufficient for an economic use of the aspirator. For the time being we may say that our samples are varied and the Ichneumonoidea are especially rich as fas as species number is concerned. The elaboration of the material will reveal what in fact we have collected. Our biggest spoil is in the number of Lepidoptera, in spite of the fact that both in absolute and in relative meaning our time of collecting was very short. This result is mainly due to the unexpectedly good catch in the nights. We have taken with us two 125 W and one 250 W Mv-lamps with the necessary choke-coil alongside with an extension cable, and where we could we erected our collecting lamps. One of our most surprising results was obtained at Hyesan, where we in fact did not expect many specimens. The hotel situated at a rather unfavourable place. Since in its environs only small patches of weed to be found, save a few beds of flowers. The woods and groves were kilometres off in the distance, and to make our situation even graver our windows did not face these wooded hills and mountains. In spite of all these we hung our lamp in the window and were taken aback to see the masses of moths that attracted. Besides a small number of Geometridae hundreds and hundreds of Noctuidae and Notodontidae came to our light. And the dangerous pest of the coniferous woods of Korea the Dendrolimus occurred in such vast numbers that it was practically impossible to make proper collecting. Our hotel at Sam-zi-yan was built in a tayga forest. Here we used our extension cable where in a nearby forest clearing we could collect undisturbed. In a pleasant, warm night - in spite of the strong moon-shine - we secured a large number of moths. Geometridae also came forward in good quantity, the representatives of the genera Boarmia, Arichanna and Hipparchus. It was quite striking not to find species of Larentia sensu lato. Among the Noctuidae many species of Phytometrina have been collected. József PAPP was kind enough to determine the plants, for which we would like to thank him hereby.
