Opius (Opiothorax) attributes Fischer, 1962, o_ nova FISCHER (1962a) described this species on the ba,sis of) two Austrian male specimens; the new female sexmaybe characterized by the following features: Antenna 38 jointed, r2 distinctly 1. 5 times longer than cuqul (32-33:21, x63), first tergite one-third as long as wide at hind, body brown and 3 mm long. In 1976 I had named the specimen at hand with question mark on the label; in 1977, on my request, M. FISCHER confirmed my determination. Distribution: hitherto known only from Austria. New to the fauna of Hungary and Slovakia (CSSR). Localities: Alacsony Tátra (= Nízke Tatry, Slovakia), Breznó, Bystra, 500-700 m, 1 o,. Hárskút, Esztergáli völgy, 1 <£. - VI-VII. Opius (Nosopaeopius) aureliae Fischer, 19 57 Antenna 35 (1 o_) and 39 jointed (1 ô'). rl slightly longer than width of stigma, r2 onethird longer than cuqul (30-34:19-23, x63). First tergite weakly rugose, evenly widening behind, proportion of its length to fore and hind width as 33:14:21. Mesonotal pit small and shallow. Propodeum strongly coriaceous. Clypeus brownish yellow; mandible, antennái joints 1-2, tegulae and legs rather pale yellow. Length 2. 5 mm. O. aureliae

, O. (Nosopoea) cubitalis Fi. and O. (Allophlebus) singularis Wesm. are extremely similar to each others. Actually, they differ from each other by their subgeneric feature. In connection with this similarity I must remark that among the specimens named as O. aureliae may occur ones with "closed" mouth, i.e. between the clypeus and mandibles a very narrow opening is to be seen. - Distribution: its known area is disjunct, Austria and U.S.A. In Austria frequent, gathered in several sites of Alps (Tirol, Styria), taken also in Burgenland too, in the Western vicinity of Hungary. New to the fauna of Hungary and Slovakia (CSSR).

Opius (Misophthora) austriacus Fischer, 1958, 6 novus On my request some specimens were kindly named by the descriptor of the species, M.FISCHER, in 1976. Antenna 21 (2 p and 1 6) and 22 jointed (1 6), according to the description antenna 32-33 jointed (FISCHER 1973). Palpi pale yellow to yellow. Legs yeUow with few brownish patterns, after description (1. c. ) legs brown. Female 2 mm long. Male sex agrees with female, its length 1.7-1.8 mm. Propodeum of the single male from Hárskút with fine and irregular rugosity, this feature is rather exceptional, namely, for the subgenus Miso phthora is characteristic the polished propodeum. - Distribution: described from the environment of Vienna, up to now further records were not reported.

Opius (Opius) breviscapus Thomson, 1895 As FISCHER had established (19 66) and, furthermore, on the basis of specimens taken in Bakony Mts. I could confirm that the distinction of O. beviscapus Thorns. , O. pal- lipes Wesm. and O. piceus Thorns, is extremely difficult. Especially O. breviscapus and O. piceus are deceptively similar to each other. Besides the features given by FISCHER (1. c. ) I could not discover further distinctive ones. Indeed, the numerous transitional forms stimulate me to suppose that the last two names, actually, refer to the same species. So it is anticipated that, first of all, by rearing of hosts the two names will prove to be synonymous. FISCHER (1968, 1971b) reported it from Mongolia too, the three females are housed in the Hungarian Natural History Museum, Budapest. Examining these females together with
