Opius (Opius) peterseni Fischer, 1964 Among from the species of the subgenus Opius it excels in its yellow abdomen, first tergite only with a brownish suffuse medially. Mesonotum along the imaginary notauli and behind reddish. Pronotum anteriorly yellow, latero-posteriorly brownish. Antenna 28 jointed. r2 conspicuously short, scarcely longer than cuqul (21:18, xlOO). r3 more than thrice as long as r2 (68:21, xlOO). Propodeum medially rugulose to weakly rugulose. My specimen was compared with a female paratype kindly lent by B. PETERSEN (Universitets Zoologiske Museum, K0benhavn). - Distribution: described from Denmark, recently listed in Austria. New to the fauna of Hungary. Locality: Kerecsend, védett erdő preserved forest), 1 g. - VII. Opius (Opiothorax) phytobiae Fischer, 1959 Tergites 1-2 and fore half of third tergite vivid yeUow, otherwise abdomen black. Antenna 21 jointed, n. rec. postfurcal. Mandible below at its base with a strong subtooth. Distribution: known only its female holotype in Poland, recently listed from Hungary too (FISCHER 1973) without any locality name. Locality: Keszthely, 1 g. - VII. Opius (Utetes) posticatae Fischer, 1957 Second tergite faintly to distinctly rugulose medially. Antenna 30 (1 g) and 33 jointed (1 g). r2 distinctly twice longer than cuqul (28:13, x63). Tergites 2-3 yellow or rusty brown. Ovipositor sheath (inlateral view) as long as first two tarsal joints of hind leg. My specimens were compared with a male identified by M. FISCHER. - Distribution: hitherto known only from its type-locality in Sweden. I saw a male from Austria. New to the fauna of Hungary. Localities: Tata, erdő. Öreg-tó, 1 g. Velem, 1 g. - VI, VIII. Opius (Allophlebus) pulcherrimus Fischer, 1958 On its taxonomy see at O. pulchriceps Szépl. - Distribution: Central Europe (Germany, Austria), new to the fauna of Hungary. Its most localities are recorded in Hungary. Localities: Budapest, Hűvösvölgy, 1 g. Olaszfalu, Alsópere, 1 g and 1 o {1 o swept in Quercetum petraeae-cerris). Szigetszentmiklós, 1 g.

swept in Galatello-Quercetum. Vállus, Büdöskút, Feketehegyek, 1 o. v-rx. Opius (Allophlebus) pulchriceps Szépligeti, 1898 Very closely related to O. (A. ) pulcherrimus F. and O. (Phaedrotoma) variegatus Szépl. O. pulchriceps and O. variegatus described from Hungary, O. pulcherrimus from Germany. On the basis of the representatives taken in the Carpathian Basin their few specific differences are compiled in a tabular form: O. pulcherrimus Fi. O. pulchriceps Szépl. O. variegatus Szépl. 1. Tergites 2-3 fully smooth, 1. Tergites 2-3 smooth, shiny, 1. Tergites 2-3 rugo-rugushiny (subgeneric dif- at most exceptionally fine- lose in a variable exference). ly and feebly rugulose to tent, sometimes only uneven (subgeneric differ- uneven, but never fully ence), smooth (subgeneric difference).
