and by the male genitalia. Some of the body characteristics are similar to those of the species Calliopum but the çf genitalia are comparatively different (surstyli united with hypopygium, a second pair of hypopygial processes present, phallus is very complex, etc.). Calliopum STRAND, 1927 C. albomaculatum (STRÓBL, 1909): 283(Lauxania) — An easily recognizable species, nevertheless needing redescription: Head 1.5 times higher long than, anterior ors inclinate, third antennái joint only 2.5 times longer than 2nd joint dorsally and less than twice longer than its width. Arista pale yellow, antennae dark reddish yellow, only apical two-thirds of third joint dark blackish brown. Genae wide, longest diameter of eyes only 2.43 times longer than smallest genal width. Mesonotum heavily dusted with grey pollen. Only 2 pairs of dc. 1 very strong prsc pair (equalling anterior dc). Acrosticals in about 4 badly arranged rows. Legs mainly black, tarsal joints 1-3 of mid and hind tarsi dark yellowish red. Hind tibia without dorsal preapical bristles. Mesopleuron with 1 very strong posteromedially situated bristle and with some shorter bristles. 2 pairs of st. Wings transparent, veins ochreous yellow. m x = 1.7, f a-í p /í p = 2.0. Calyptrae fuscous, haltères black with brown stalk. Abdomen subshining with grey pruinosity. Material studied: \ çf : "Austria sup., Kremsmfiinster], CZERNY", "Calliopum albomaculatum STRÓBL" det. L. CZERNY. Calliopum splendidum sp. n. (Figs. 35-37) Shining black species. Arista with short (only 0.05-0.055 mm long) pubescence. Third antennái joint only twice longer than two basal joints combined. Antennae reddish yellow, apex and upper part of third antennái joint brownish. 0 + 3 dc pairs. 1 pair each of stigmaticals, mesopleurals and sternopleura Is. Acrosticals in 4 distinct rows. Wings yellowish with yellow venis. m x of holotype: 1.29, of paratype $ : 1.30. Wing length: holotype çf : 4.19 mm, paratypes: 4.32, 4.54 mm, width: holotype: 1.67 mm, paratypes: 1.73, 1.76 mm. Fore legs completely black (at most knees lighter). End of mid and hind femora, majority of mid tibia, entire mid and hind tarsi and hind tibia red. Mid tibia on proximal half brown dorsally. Male mid metatarsus ventrally with a black brush of short but thick bristles. Ventral apical part of çf hind tibia with a patch of comparatively long and thick, black bristles, çf genitalia (Fig. 35) with thick black thorns at ventral base. Surstylus (Fig. 36) wide at base, strongly curved with sharp tip (Fig. 35). Gonites (Fig. 37) bristly with 2 apical processes, the more ventral one curved. Dorsolateral bulbs on $ postabdomen ear-like and much smaller than in C. elisae (MEIG.). — Body length: holotype: 3.77 mm, paratypes: 3.63, 3.86 mm. Holotype çf : "Hungary, Budakeszi, Hársbokorhegy, Tervterület, 1953, VIII. 12., leg. MIHÁLYI". — Paratypes: \ çf ,\ 9 : data same (all type-specimens in the HNHM). Calliopum splendidum sp. n. is similar to C. elisae (MEIG.) but it diners by its darker mid tibia, by the çf genitalia (smaller hypopygium, shorter surstylus; its gonites have 1 short and straight and 1 long, curved process instead of two long, curved processes of elisae) and by the $ genitalia (dorsolateral bulbs are ear-like and much smaller). A partly revised list of the Palaearctic species of Calliopum STRAND: aeneum (FALLÉN, 1820), albomaculatum (STRÓBL, 1909), annulatum (BECKER, 1907)*, elisae (MEIGON, 1826), geniculatum (FABRICIUS, 1805), hispanicum (MIK, 1880)*, rufipes (CZERNY, 1932), simillimum (COLLIN, 1933), splendidum sp. n. Still doubtful species (in all probability they are synonyms): atrimanum (MEIGEN, 1826), atrocoeruleum (BECKER, 1895)**, nitens (LOEW, 1858)**, nigripes (MACQUART, 1835), virtipennis (MEIGEN, 1926). Several specimens identified by BECKER as atrocoeruleum and nitens from the collection of the Zoological Museum, Berlin and the Hungarian Natural History Museum were studied and it was found that all of the specimens belong to elisae (MEIGEN, 1826). As BECKER, who described atrocoeruleum and who knew the type of nitens of LOEW identified these specimens, it is very probable that both the species are synonymous with elisae (MEIGEN, 1826). Unfortunately, type-specimens have not been found either in LOEW'S or BECKER'S collections. * Type-specimen(s) seen. ** ? syn. of elisae (MEIG.)
