ACROCERIDAE Ogcodes varius Latreille in Olivier, 1812 Members of this family are rarely recorded. I collected only a male of O. varius on June 27th 1992 in Tiszapüspöki. For some time I observed it hovering twenty centimeters above the ground in a marshy poplar forest. In the following years In vain I tried to collect more specimens on the same spot in later years. THEREVIDAE Pandivirilia fuscipennis (Meigen, 1820) In the Pilis Mountains between Pilisszentlászló and Visegrád on May 25th 1996 I caught a female of P. fuscipennis in the sunshine on foliage. I was so much impressed by the size of the specimen, that, though I am not a collector of Therevidae, I took it home. It turned out to be only rarely collected in Hungary. CONOPIDAE During my excursions in Hungary I paid special attention to these flies. Although the conopid faunas of other European countries are quite well known, the family has not got the attention in Hungary what it deserves. Conops silaceus Wiedemann in Meigen, 1824 It is mainly known from Southern Europe, though it is mentioned also from Belgium. It, however, has not been mentioned from Hungary. I caught one male in Péterhalmierdő on August 6th 1994. I found it on a Compositae. Physocephala curticornis Kroeber, 1915 P. curticornis looks like a dwarf P. vittata (Fabricius, 1794). It was collected in Hungary before, but appears to be a very rare species, which has been further collected only in Russia, Ukrain, Tajikistan and Kirghizia. Therefore, the male collected on June 16th 1995 in Dabas on Compositae deserves mention. Myopa extricata Collin, 1960 M. extricata belongs to the group of spring species of the genus Myopa with infuscated wings. According to the Catalogue of Palaearctic Diptera it was collected in Hungary before, but there is no specimen in the Hungarian Natural History Museum of Budapest to prove it. This is quite surprising, because the species does not seem to
