It seems that the KASZAB expeditions provided an appeal for the Hungarian entomologists. Therefore it is not surprizing that subsequent to his activity several collecting trips were carried out, partly supported by the HNHM providing equipments and logistics. Most of the participants of the subsequent expeditions of Hungarian entomologists to Mongolia were lepidopterists (GY. FÁBIÁN, P. GYULAI, M. HREBLAY (f), L. PEREGOVITS, G. RONKAY and Cs. SZABÓKY) (cf. PEREGOVITS 1989). Consequently, the HNHM Lepidoptera collection, as well as some private collections in Hungary contain important material collected after KASZAB'

s expeditions in Mongolia; and even more importantly numerous primary and secondary types of the species discovered by these expeditions are preserved in Hungarian collections. The last Hungarian entomological expedition to Mongolia was earned out during the summer of 2005, when BALÁZS BENEDEK and TIBOR CSŐVÁRI travelled more than 4000 km throughout the country. The main purpose of this trip was to collect noctuid moths, but attempts were also taken to collect butterflies. The aim of the present paper is to report the faunistic results of this expedition: (1) to provide information about the collecting sites and the applied methods; and (2) to present a list of the recorded Macrolepidoptera species with indications (*) to taxa new for the Mongolian fauna. MATERIALS AND METHODS Diurnal moths and butterflies were collected randomly, depending on weather and habitat conditions. Moths were collected every night at light applying a 250 W mercury vapour bulb illuminating a white sheet, and four portable (semi-automatic) light traps with 8 W UV tubes. Adults of several nocturnal species, especially members of the genus Cucullia SCHRANK, 1802 and the subfamily Plusiinae, were also taken by net at dusk and the early evening hours, when specimen were feeding on various flowering plants (but mostly of Silène spp.) or searching for nectar sources. Specimens were arranged in cotton layers every morning after collecting activities in situ. The collecting site was numbered. Specimens were pinned, labelled and set subsequently in the laboratory of the HNHM. The collected material is listed under the heading "Results" in systematic order according to families. The number(s) of the collecting site(s) (with the number of the collected specimens in brackets) is(are) given for every species captured.
