Many works an dedication to find out to modern range of steppe marmot in Volga region. It is known less about former distribution this species in region. We tried to unite data concerned to inhabitancy of marmot in Penza region. On the basis of literature (Falk, 1821; Bogdanov, 1871; Sprygin, 1923, 1925; Kirikov, 1966, 1980; Denisov et al., 1984; Dmitriev et al., 1994, 1996), the report of hidronyms "The rivers of Penza region" (Zimin, Eremina, 1989) and list of countries of Penza region, on generally method (Tupikova, Komarova, 1979), it was complied cadastre and map (see Fig.) of historical distribution of steppe marmot in Penza region. Cadastre includes 52 points of finds and contains following data: number on map, literature, address (modern and old name of geographical point), co-ordinates, trace of inhabitancy (burrows site (bootans), remainders of bone, archives data, inquirely data, toponyms). The old names of countries were collated with map of Penza province compiled in 1911. Latitude and longitude places of find colonies or trace of inhabitancy marmots were defined with topographical map "The republic Mordovia and Penza region" (M 1 : 200000).

From figure it is looks, that before period of agriculture bobac was distributed in all steppe districts (south, central parts of region and also north district on the left bank of Sura). That data also partial explain a failure in reacclimatization and may be as a ground for plan further investigations.
