Opius (Aulonotus) holconotus Fischer, 1958, o nova This species was; described by FISCHER on the basis of two males originating from England which turned up in MARSHALL'S CoHection purchased by the Hungarian Natural History Museum, Budapest; consequently, the) holotype and one paratype are deposited in this museum; Hym. Typ. 2495-2496, No. 2495: 6 holotype, "Bfmg" England, Coll. Marshall, No. 2496: 6 paratype, "Britain??", "1979", Coll. Marshall. Since its description no any contributions were published of this species. Among the four specimens (1 g and 3 ó') taken in Bakony Mts. one represents the new female sex. Its ovipositor sheath (in lateral view) hardly longer than first tergite. r2 1. 6 times as long as cuqul (21:13, x63). Antenna somewhat longer than body, 23 jointed. Brownish black, legs pale yellow. Body 2. 2 long. - Distribution: England, new to the fauna of Hungary. Localities: Iharkút, Laposak, 1 6, Vinyesándormajor (Bakonyszentlászló), 1 Zirc, Bocskorhegy, 1 g and 1 6" swept in Querceto-Carpinetum. - V and VII. Opius (Utetes) hostium Fischer, 1964 Head (from above) behind eyes constricted (in comparision with O. hilaris Fi. and O. posticatae Fi. ). Antenna 25 jointed. First tergite 1. 5 t mes as long as broad behind, its sides nearly parallel (or scarcely widening behind), its surface longitudinally uneven. Sternaulus very finely crenulated. Temple (in lateral view) shorter than horizontal diameter of eye (10:13, xlOO). The descriptor of this species, M.FISCHER, identified it as O. hilaris in 1977, however, the elongated thorax relegates it unambiguously to O. hostium which I could confirm by the examination of the holotype kindly lent to me by FISCHER. - Distribution: described from Germany, reported from Austria. New to the fauna of Hungary. Locality: Iharkút, Tisztavíz, 1 g. - VI. Opius (Opiothorax) inflammatus Fischer, 1962 Antenna 20 (1 (j>) and 21 jointed (3 o), according to the original description (FISCHER 1962b) antenna 27 jointed, recently I saw a Female with 23 joints named by FISCHER and taken in Salzburg (Austria). Head (in dorsal view) twice or just less than twice as broad as long (44-45:24, xlOO). Light colour of body brownish yellow, face and temple of the four females from Bakony Mts.

, deviating from the description, with brownish yellow ground colour, face with more or less dark suffuse. - Distribution: up to now known only from Austria. New to the fauna of Hungary. Locality: Lesenceistvánd, Uzsapuszta, 4 <j>. - VIII. Opius (Utetes) insertus Fischer, 1971 (= exsertus Thomson sensu Fischer, 1958) Third femur 3.5 times as long as broad (34: 10, x63). First tergite one-third as long as broad at rear (22:17, x63), fore-middle surface of its hind half rugose, otherwise smooth. Antenna with 31 joints. Mesonotal pit elongated dash-like. Body black. Cheek, inner and upper margin of eye reddish; tegulae, legs and fore sternites yellow. Body 2. 8 mm long. Distribution: observed in England, North and Central Europe, Japan. Perhaps disjunct in its distribution. New to the fauna of Hungary and Transylvania (Romania). Localities: Bártfa (=Bardejov, Slovakia), Csergő Mts., dol. Hertnická, 1 g. Felsőörs, 1 6. Oroszmező (= Rus, Transylvania), 1 Pálháza, Ördögvölgy, 1 g. Velem, erdő, 1 g. . V-VII. Opius (Hypocynodus) larissa Fischer, 1968 A species up to now known only from Mongolia (FISCHER, 1968); its holotype is housed in the Hungarian Natural History Museum, Budapest; Hym. Typ. No. 2481.
