to be most frequent below I5OO m. The dispersal of Nabis ferus shows similar features as that of the latter species (Table l). Kalmanius flavomarginatus lives in moist biotopes. It often occurs on northern slopes, and/or in valleys open to the North. It is familiar from the high-mountain and mountain steppe regions up to the alpine zone. Bather often, it may be collected on the fringe of birch woods or in the woods of birch and conifers, furthermore, in glades or seldom in the outer skirts of the woods, in the undergrowth. On the southern border of its distribution it sometimes occurs under semi-desert conditions, but even here it lives only on moist spots located between sandhills, which means that it keeps to rich vegetation. On- higher localities it lives on agricultural fields as well. On one occasion it had also been collected by a Malaise trap. Dolichonabis nigrovittatus is most frequent in steppes and mountain steppes, sometimes it occurs on the fringe of woods; exceptionally in the outer skirts of thin woods. It is rarely found in the alpine zone but in higher regions it may also be collected on agricultural fields. Nabis ferus seems to be most frequent in steppes and in river valleys, or near the banks of rivers. It favours biotopes with rich vegetation and also occurs along birchwoods. Sometimes it may be found on sand-hills visiting Tamarix shrubs. On one occasion it had been collected by a Malaise trap. The known biotopes of Dolichonabis americolimbatus are located lower than 1000 m. Nabis intermedins is known from an altitude of I4OO m (Table l). These - but especially the former - may surely turn op from the higher regions, too. Beduviolus inscriptus has been collected between 1000-2000 m (Table l) , in Mongolia it may be more frequent above I5OO m. This species lives mostly on moist biotopes with rieb vegetation and is most frequent in wooded steppe and in steppe regions. It was captured from Caragana, on a dry, mountain steppe.
