it penetrated into Mongolia through. Siberia and found its way as far as the south-western parts of Mongolia. Reduviolus inscriptus (Big. 3), Dolichonabis tesquorum (KERZHNER, 1968) and Prostemma kirboti (KERZHNER, 1968) are frequent - like the former species - in the regions of North Mongolia and Nabis brevis (Pig. 3) was captured in North and West Mongolia, resp. In view of their geographical range it may be taken for granted that they reached Mongolia from Siberia. Dolichonabis americolimbatus and Nabis intermedius are most frequent in the Chentej aimak region but these seem to be absent in Cojbalsan aimak, i. e. in the easternmost regions of Mongolia (Pig. 4). Halonabis sareptanus

, Aspilapsis pallidus

, Nabis palifer

, Nabis sinoferus sinoferus and Nabis brevis ferghanensis (?) have invaded Mongolia from Central Asian direction, and these species live in the south-eastern part of Mongolia, i.e.in regions bordering Dsungaria and Inner Mongolia (Pig. 4). Nabis palifer is the only one among them that was mentioned as from north-western Mongolia (KERZHNER, 1963). In the nabid fauna of Mongolia there are also two taxa of Chinese - probably Manchurian - origin. These, Halonabis sinicus and Nabis sinoferus seidenstückeri

, may inhabit mainly the north-eastern parts of Mongolia (Pig. 3) but Halonabis sinicus has found its way into the Gobi-Altai and the Baykal Region, respectively. The Mongolian nabid fauna, therefore, consists of species that invaded from Siberia, East-Siberia, Central Asia and Chine (Manchuria). Among the nabids there seems to be no taxa of MonPig.
