FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXVIII. 2. 1975 p. 363-368 377. Bombyliidae II. (Diptera) Ergebnisse der zoologischen Forschungen von Dr. Z. Kaszab in der Mongolei By V. E. ZAITZEV (Received Mai 15, 1975) Abstract: - 20 Bombyliid species are reported from Mongolia with locality data and distribution. This article is the result of studying of the material collected in Mongolia in the years 1967 and 1968 by Dr. Z. KASZAB. It contains the list of species of Bombyliidae Tomophthalmae and continues this range of our publications. The previous paper about the mongolian Bombyliidae from collections of Dr. Z. KASZAB (ZAITZEV, 1974a) has contained the list of species Bombyliidae Homoeophthalmae. Dr. Z. KASZAB has collected 133 specimens of Bombyliidae Tomophthalmae belonging to 20 species. The species Petrorossia albissima ZAITZEV, Exoprosopa latiuscula LOEW and Villa occulta WIED, were found in mongolian fauna first by Dr. Z. KASZAB. Now we distinguishe 37 species Bombyliidae Tomophthalmae from Mongolia. These are three more species of Villa in Dr. Z. KASZAB'

s collections, but the accurate determination of these species is not possible by reason of very poor conservation of specimens. The additional data to labels are given in the papers of Dr. Z. KASZAB (1966, 1968a-b). The author is glad to express his acknowledgement to Dr. Z. KASZAB who has sent the material to Zoological Institute of USSR and has given the possibility to study it.
