13 (12) First segment of ovipositor in lateral view straight or even concave,, mar­ginal bristles arranged in a continuous row. 14 (15) Head behind covered with white hairs. Third antennái joint about 3-4 times as long as wide ampullacea VILLENEUVE, 1922 9 15 (14) Head behind covered with black hairs. Third antennái joint 2.5, seldom 3 times longer than wide ilhistris (MEIGEN, 1826) 9 16 (1) Basicosta creamy white. 3 postsutural ac. Abdomen of males shiny, that of females covered by thin whitish dust. 17 (18) Only 1 ad bristle on mid tibia. Frons wider than third antenna! joint, half of it occupied by interfrontalia. Cheeks of male of about 1.5 antennái breadth, those of females even wider and whitish grey dusted. — Very common in open fields and towns sericata (MEIGEN, 1826) 9cf 18 (17) 2-4 ad bristles on mid tibia. 19 (24) Males. Abdomen glossy, undusted. 20 (21) Frons narrow, hardly wider than antenna, interfrontalia 1/3 of frons. Fifth tergite without strong discal setae (Fig. 5) richardsi COLLIN, 1926, çf 21 (20) Frons conspicuously wide, 2-4 times wider than third antennái joint. Last tergite with long, strong discal bristles (Fig. 3). 22 (23) Sternites covered with long, dense, brush-like hairs. Frons 4 times wider than antenna. Cheeks 1.5-2 times as wide as antenna. No marginal bristle on third tergite. Costal spine well developed (Fig. 2), over 2 times longer than spinules near them (often broken on one or both sides). Our largest Lucilia species, 7-12 mm. — Collected in small numbers mainly on plaines. ZUMTT (1956) supposes, that IJ. pilosa BARANOV, 1926 may be identical with this species pilosiventris KRAMER, 1910, çf 23 (22) Sternites with the usual hairs. Frons 2 times wider than antenna. Cheeks 1.25 times as wide as antenna. 2-4 long marginal bristle on third tergite. Costal spine short, hardly longer than spinules. Smaller, 6-7 mm. — Rare in Hungar} 7 , occurs mainly on meadows of plains regalis (MEIGEN, 1826) çf 24 (19) Females. Abdomen thinly, uniformly white dusted. 25 (26) Large, 8-10 mm in length. Costal spine conspicuous!} 7 long (Fig. 2). Cheeks silvery white gleaming, nearly 2 times as wide as antenna. Inter­frontalia as wide as one of the parafrontalia. 2-3 ad on mid tibia nearly equally strong. Discal bristles on fifth tergite strong and numerous (Fig. 3). Brush-like hairs on sternites much less developed than on males pilosiventris KRAMER, 1910, 9 nova 26 (25) Smaller flies, usually under 8 mm. Costal spine inconspicuous, hardly longer than spinules. Proximal ad bristles on mid tibia much shorter than distal one. 27 (28) Last tergite with strong discal bristles (cf. Fig. 3). Third tergite bearing 2-4 long marginal bristles, latter reaching well over middle of next tergite. Parafrontalia rather narrow (Fig. 4). regalis (MEIGEN, 1826) Q nova
