The present paper reports for the first time the occurrence in Hungary of H. diana, H. actaeon and Oe. leporina on ground of home collectings. The development of H. diana in roe deer and of H. actaeon in red deer as well as the morphology of the larvae of these Hypoderma species have already been briefly described by KERTÉSZ (1897), however, based on results of experiments conducted abroad. As shown by our results, the Hypodermatid-fauna of games in Hungary fits well in the fauna picture of Hypodermatids in Europe (ZUMPT, 1965; GRÜNEM, 1966). Life cycle of H. diana . We were able to detect larvae of H. diana from each of the 22 regions from where roe deer older than 15 months were examined. This parasite was found to be very common in roe deer, common in red deer, and occassional in fallow deer and moufflon. In roe deer and red deer (presumably in fallow deer, too) larvae can develop to maturation, however, in the moufflon they usually die before reaching the 2nd larval stage. Among the examined 3 species the imagoes of H. diana are most likely to start the wing at the earliest: the bulk in April, considering that mature larvae can be found predominantly from mid-February tiU mid-March and the pupation period can hardly exceed 20-25 days (at 20 °C it lasts 13-18 days). This conclusion is also supported by the collecting time of the free imagoes, moreover, by the fact that kids usuaUy do not become infected during the year of their birth, + ' while in red deer calves, the birth The main period of the birth of kids was claimed by von RAESFELD (1970) on the basis of several thousand data of observation to faU between 15th May and 15th June in the Federative Republic of Germany. This is confirmed also by the observations of professional hunters in Hungary.
