Baryproctus barypus (Marshall, 1885) (=Bracori) The host of this species has been unknown. The closely related species B. ussuriensis Telenga was reared by Nartshuk (1977) from L. brevipilosa galls collected in Mongolia. Distribution: This species is sporadic in Europe. Rearing results: In the present investigation it developed in L. rufitarsis and L. similis galls. Rearing data: L.] rufitarsis: 1:1, 2:1; L. similis: 15:1. 3 specimens were collected from 3 localities. Braconidae indet. One specimen was reared from a L. lucens gall collected in Budaörs. The identification is in process. Rearing data: 13:1. PTEROMALIDAE Stenomalina liparae (Giraud, 1863) (=Pteromalus) The species was described by Giraud (1863), on the basis of adults reared from Lipara lucens. Since then, it turned up many times in the material following a thorough investigation. The most common host of the species is L. lucens. (Wagner 1907, Blair 1932, Ruppolt 1956-57, Mook 1961, Fulmek 1968, Waitzburauer 1969, Chvála et al. 1974, Hudek etal. 1981, De Bruyn 1987, Wolf 1988, Dely-Draskovits etal. 1993, etc.). Besides the host mentioned above, in several cases it reared from galls of other Lipara species (L. pullitarsis and L. rufitarsis Chvála et al. 1974 and De Bruyn 1988). The detailed description of the infected larvae is given by Ruppolt (1956-57). Distribution: It is a European species. Rearing results: In course of our investigation it emerged from galls of all the four Lipara species living in Hungary. It reared most often from L. lucens. Rearing data: L. lucens: 1:6,3:3,7:3, 10:11, 14:3, 19:2, 21:8, 22:1, 25:1; L. pullitarsis: 21:4, 25:7; L. rufitarsis: 21:2,; L. similis: 21:15. It was found at 9 sites in 66 galls. The largest number came from Hortobágy National Park, Margitai-erdő, where 15 galls of L. similis and 11 galls of L. pullitarsis yielded this species. This result is quite remarkable when considering that throughout our research L. pullitarsis proved to be infested by Hymenoptera only in 13 cases. S. liparae gives 15% of all the occurrence, just like P. aboletus. Pachyneuron formosum Walker, 1833 Giraud reared it in 1863 in France from L. lucens galls. This species, common in the whole of Europe was reared from reed shoots from Leányfalu.
