golian origin. Most of the species are of Siberian origin but taxa of Central Asian, Manchurian, as a matter of fact, European and North American origin are also existing in the fauna.The latter ones got into the country via Siberia. The species invading from Siberian direction have reached Mongolia through the central and estern parts of the country's northern border. The Central Asian species have invaded Mongolia through Dsungaria and the ranges of Thien Shan, while the Chinese (Manchurian) taxa have reached the country on her eastern parts (Cojbalsan and Suchebaator aimak) . Without doubt,the species invading from Siberian direction have been the most prosperous ones, since, these have accomplished the widest distribution. They have successfully captivated the country's northern parts and western regions as well (Fig. 5) but only one of them, Nabis feroides mimoferus , was able to get into the Gobi,or rather, into the eastern part of the country, through which it ultimately reached the Central Mongolian and North-Chinese regions. With the exception of the latter,the spread of the species invading from Siberia shows close similarity, namely they can be found almost everywhere in the northern parts of the country. The species immigrating from EastSiberia managed to captivate only the eastern parts of the area mentioned before. The species that invaded from the Central Asian direction found their habitats in the south-eastern parts of the country; it is Nabis palifer alone about which north-western data are at disposal. Especially noteworthy is the fauna of the south-western part of Chovd aimak, since the representatives of Siberian and Central Asian fauna meet each other on a rather large area. The taxa of Chinese origin are likely to be most frequent in the easternmost part of the country, but they have reached Central Mongolian, as a matter of fact, they got - through Mongolia - up to the Baykal region as well. The aforementioned details indicate that the Mongolian nabid
