Localities: Gyula, csatornapart, 1 o. Kapolcs, Kálomis, 2 6. Miskolctapolca, 1 V-VI. Opius (Opiostomus) clausus Fischer, 1958 Antenna 26-27 jointed (0$, its 3rd joint thrice longer than broad (7:2, x63). Lower base of mandible with a subtooth in contradiction with FISCHER' s figure (1973, p. 72, Abb. 56). Sternaulus normal in depth, though with extremely fine crenulation well to be seen in a special angel of incidence. Propodeum rugose, on its upper part with a more or less visible transverse carina; this feature reminds of O. (Opiognathus) propodealis Fi. and O. (O. ) woer- ziphagus Fi. r2 twice as long as cuqul (o 38:$0, 6 40:17, xlOO). Body blackish brown. Clypeus, cheek and mandible yellow, palpi pale yellow. Antennái joints 1-3 yellow, joints 4-7 gradually darkening, further ones blackish brown. Legs vivid yellow. First tergite rather brown, second and third tergites brownish yellow. 1. 8 mm long (oi). - Distribution: one of the most interesting Opius species turned up in Bakony Mts. , Hungary. Hitherto only its two localities were reported in Austria (Eichgraben) and Japan (Sapporo). The two localities imply its disjunct area, however, it is expected to be found in several parts of the Palaearctic Region. New to the fauna of Hungary. Locality: Farkasgyepü, 2^ + 16' swept in Melico-Fagetum in June. Opius (Aulonotus) comatus Wesmael, 1835 Stigma elongated, six times as long as its greatest width, rl originates slightly proximal from its middle. r2 one-third longer than cuqul (19:13, x63), r3 2.3 times longer than r2 (45:19, x63). Antenna 23 jointed, its third joint five times, its penultimate joint 2. 5 times as long as broad. First tergite 1.4 times as long as wide at hind, graduaUy broadening posteriorly, its hind width twice greater than basal width, with longitudinal and not rough rugosity. Head of female from Fenyőfő entirely brownish black, except yellow mandible. - Distribution: a Holarctic species. Recorded in several European countries, recently observed in Mongolia too. New to the fauna of Hungary. Localities: Csákvár, park, 3 o_. Fenyőfő, Kisszépalma, 1 Jósvafő, Farkaslyuk, 1 p. Németbánya, vadászház környéke, 1 swept in Fagetum sylvaticae. Vértes Mts. , Csókakő, 3 c^ and 2 6. Vértes Mts., Fanienvölgy (Szár), 1 (j>. Zamárdi, erdő, 1 Zamárdi-felső, 1 - V, VIII-IX, frequent in September. Opius (Nosopoea) connivens Thomson, 189 5 Propodeum rather rugulose, its middle almost smooth. Antenna 26-28 jointed (according to the description 25 jointed, Fischer 1973). Notauli reaches mesonotal pit and gradually shallowing posteriorly. First tergite somewhat longer than wide at hind (26-23:22j 20, xlOO). The four females taken in Bakony Mts. deviate mostly in its colour pattern from the description (1. c). Face almost fully brown to black. Abdomen brown or brownish black, first tergite black except yellow or dark yellow tergites 2(-3), the single female from Bakonybél with black abdomen except brown 2-3 tergites. - On my request two females from Felsőörs were identified by Fischer. O. connivens is extremely similar to O. (Misophthora) tirolensis Fi.; the two species are differentiated as below: O. connivens Thorns. O. tirolensis Fi. 1. Body relatively strong, head (in dorsal 1. Body relatively slender, head (in dorsal view) behind eyes somewhat less con- view) behind eyes somewhat more constricted, so head rather cubic-like. stricted, so head less cubic-like. 2. Propodeum always rugose in any size, 2. Propodeum smooth, shiny, at most ausually faintly rugose and smooth at its round lunule and along its hind margin middle. (hardly visible) uneven. 3. Notauli reaches mesonotal pit. 3. Notauli does not reach mesonotal pit, i.e. notauli restricted to declivous part of mesonotum. Distribution: a rare species, recorded its few localities in Sweden and Denmark. New to the fauna of Hungary. Localities: Bakonybél, Hubertlak, 1 <j>. Felsőörs, 2 (j>. Sümeg, Sarvaly, 1 çj>. - V-VI.
