Várpalota, Várvölgy, 1 g swept in Querceto-Carpinetum. Visegrád, ló. - VI-IX. Remark. - B. melanosoma Szépl. was described on the basis of one male and one female specimens (1. c. ). Since FISCHER' s report (1973) on the lost of the type-series the male specimen was found by me in our collection. I designated it as the lectotype of B. mela nosoma, its data: "Budapest Zugliget, VI. 28. 1895." and is housed in the Hungarian Natural History Museum, Budapest; Hym. Typ. No. 1791. The male sex proved to be a representative of B. brevisulcus

. The female sex seems to be lost. Biosteres (Biosteres) colorativentris (Fischer, 1957) Abdomen brown to dark brown. Antenna with 39-40 joints, rl as long as width of stigma. Stigma almost parallel-sided. N. rec. rather interstitial. - Distribution: sporadically in Sweden, Germany, Austria. New to the fauna of Hungary. Localities: Budapest, Hűvösvölgy, 1 g. Kisdobsza, lg. - V, X. Biosteres (Biosteres) impressus (Wesmael, 1835) ACHTERBERG (1975) keeps the name impressus as synonymous with B. carbonarius (Nées); I am rather inclined to accept his new taxonomical appointment. The rearing results in the future wiU, certainly, confirm his comprehension. According to my opinion in the case of the synonymization the form of impressus represents a race within the species of B. car bonarius bound to the male sex. - Distribution: sporadic in North, West and Central Europe. New to the fauna of Hungary. Localities: Alacsony Tátra (= Nízke Tatry, Slovakia), Breznó, Mlynná dolina, 9001200 m, 1 6. Bártfa (= Bardejov, Slovakia), Csergő Mts. , dol. Hertnická, 1 6.

Biosteres (Chilotrichia) punctiscuta (Thomson, 189 5) Easily identifiable as B. rusticus; their specific differences are tabulated below: B. punctiscuta (Thorns.) B. rusticus (Hal. ) 1. Antenna with 33-36 joints, first flagellar 1. Antenna with 35-40 (o_) and 35-45 (6) joint nearly thrice aslongas broad (14:5, joints, first flagellar joint slightly xlOO). more than thrice as long as broad (16:5, xlOO). 2. Scutellum punctated, its hind third ru- 2. Scutellum smooth, its hind third to gose. fourth rugose. 3. Ovipositor sheath long, as long as hind 3. Ovipositor sheath short, as long as tarsal joints 1-4 (in lateral view). hind basitarsus. 4. rl shorter than width of stigma. 4. rl somewhat longer than width of stigma. 5. Femora rather thick, third femur four 5. Femora rather thin, third femur five times as long as broad. times as long as broad. Distribution: listed only its five localities in Denmark, France. New to the fauna of Hungary. Locality: Herend, Középső Hajag, 1 g and ló'. - IV. Remark. - In 1977 Jakimavicius described a new species as Opius moldavicus

. On the basis of its description the species is a representative of the genus Biosteres Förster (B. moldavicus Jakim. , stat. n. ) on one hand, and on the other in all probability it is a synonymous name of B. punctiscuta (Thomson, 1895); the re-description of B. punctiscuta given by Fischer (1973) concur in every respect with that of B. moldavicus (? syn. n. ). Biosteres (Biosteres) remigii Fischer, 1971 Antenna 36 jointed, last 8-10 joints subcubic to cubic. First tergite a quarter longer than wide at hind, cuqul distinctly 1. 5 times longer than rl. Body brownish black (fading?).
