3. Clypeus white, deeply emarginated. Larger, 8.0 mm. Rare. (Central Russia, West, East and North Europe, Tien Shan and Kamtchatka) P. declinatus (Förster, 1854) - Clypeus dark, slightly emarginated. Length: 7.0 mm. Sporadic. (Europe, Russia, Kola Peninsula, Caucasus, Tien Shan, Kamtchatka, Sakhalin, Balkans, Asia Minor, Mongolia and North America) P. vagus (Fabricius, 1781) 4. Stigma black, brown or bicolour and at least apex of hind femur black. Cerci shorter than sawsheath. Mesopleuron black 5. - Legs and stigma entirely yellow. Cerci longer than sawsheath, clearly overprojecting. Mesopleuron yellow. Larger: 6.1 mm. (Mongolia) P. mongolovagus sp. n. 5. Clypeus like entire head black (but clypeal anterior margin sometimes white), thorax black, only corners of pronotum may be white. Stigma black or dark brown. Hind tarsus shorter than hind tibia. Small species: 4.0-5.5 mm. Sporadic. (Europe, Russia, Kola Peninsula, Caucasus, Tien Shan, Kamtchatka, Balkans, Asia Minor and North America) P. obductus (Hartig, 1837) - Clypeus and infraocular area white. Pronotum and tegula white. Postocellar area behind eyes with ochraceous band. Stigma bicolour: brown with light brown upper margin. Hind tarsus as long as hind tibia. Larger: 5.6-5.9 mm (Japan) P. hayachinensis Haris and Zsolnai, 2007 Pristiphora (Pristiphora) rubrocaudata sp. nov. Holotype: female, Mongolia, Central aimak, Bugijn az achuj im Geb. Bogdo ul, 36 km SW. from Ulan Baator, 1850 m, 10. 06. 1968, exp. Dr. Kaszab. The holotype is deposited in the Hymenoptera collection of the Hungarian Natural History Museum, Budapest. Female. Body black. Labrum, mandibles reddish. Palpi whitish. Base and apex of sawsheat reddish. Coxae, trochanters, basal third of fore femur, most of middle femur, hind femur entirely brownish black. Tibiae, anteriror and middle tarsi whitish. Hind tibia with wide brown apical ring. Hind basitarsus white with brown apex, other tarsal segments of hind tarsus and last tarsal segment of fore and middle tarsi brown. Wings subhyaline, costa, subcosta and stigma yellow. Frontal, ocellar area and upper halves of inner orbits finely, uniformly and moderately deeply punctured. Temples and vertex with moderately sparse minute punctures, shiny. Pronotum with dense, moderately deep punctures, bluntly shiny. Mesonotal lobes with small, dense and uniform punctures, moderately shiny. Mesoscutellum smooth and shiny. Mesoscutellar appendage and postsuctellum with sporadic punctures, moderately shiny. Mesopleuron smooth and shiny. Abdominal tergites with very fine granulated surface sculpture, moderately shiny. Head and thorax sparsely covered with short white pubescence about half as long as diameter of front ocellus. Ratio of antennái segments: 5 : 4 : 21 : 21 : 19 : 18 : 17 : 16 : 19. OOL : POL : OCL: 12:16:9. Anterior margin of clypeus truncate. Gena as long as diameter of front ocellus. Head behind eyes gently contracted (subparalell). Hind margin of head smooth (without carina). Pentagonal frontal area not carinated, slightly sunken. Length of hind basitarsus : length of hind tibial spur : apical width of hind tibia: 13:7:9. Length of ovipositor : length of hind tibia: 57 : 80. Claw with inner tooth that is sometimes very short, sometimes longer about 3/4x as long as apical tooth but never bifid. Apex of sawsheath in dorsal view wide, apical width of sawsheath in dorsal view : apical width of hind tibia: 5 : 3. Sawsheath deeply emarginated. Apical hairs of sawsheath withish, dense and strongly directed inwards (Fig. 2). Length: 4.9 mm. The new species is closely related to Pristiphora bensoni Lindqvist, 1953. The new species larger and the reddish colour of the basal and apical part of the sawsheath clearly differs it from Pristiphora bensoni (Lindqvist, 1953). Amauronematus (Brachycoluma) mongoloviduatus sp. nov. Holotype: male: Mongolia, Chovd aimak, 3 km N. of Somon Uenc, Tal Uenc gol, 1450 m, 02-03. 07.1966, exp. Dr. Z. Kaszab. The holotype is deposited in the Hymenoptera collection of the Hungarian Natural History Museum, Budapest. Male. Body elongated. Head straw coloured including mouthparts with large black frontal spot covering vertex (but not temples), ocellar area and inner upper orbital area (although narrow inner orbits remain pale) projecting down right above antennae. Antenna yellow, dorsal part of scape and pedicel black, dorsal part of antennái segment 3 and 4 dark brown other segments dorsally yellowish brown (somehow darker than below). Thorax black, yellow: pronotum dominantly (except black anterior line), narrow posterior margin of mesonotal lateral lobes and upper anterior mesopleural fleck. Cenchri greyish white, narrow and elongated. Legs yellow, middle and hind coxae with basal black spot. Wings hyaline, costa, subcosta and stigma yellow, venation yellowish brown. Abdomen yellow. Abdominal tergites 1-5 black. Tergites 6-8 with gradually smallered black horisontal strips. Head and thorax covered with sparse and whitish pubescence. Ratios of antennái segments: 3:3:16:15 : 14 :12 : 11 :10 :11. Last antennái segment very flattened. Longest diameter of eye: length of 3rd antennái segment: 21 : 16. Antenna about as long as head and thorax combined including propodeum. Clypeus roundly emarginated. Clypeal emarginaton about 0.4* as deep as clypeal median length. Head strongly contracted behind eyes. Gena narrow, about 1/3* as long as diameter of front ocellus. Head without hind carina. Pentagonal frontal area carinated and deeply sunken. Frontal area, temples and vertex with coriaceous surface sculpture, moderately dense on frontal area rather sparse on tern-
