Body entirely dark brown; mouth-parts yellowish brown; petiole yellow; 2nd and 3rd tergites brown medially. Antenna entirely dark brown, a little paler than head. Wings hyaline; stigma and veins brown. Legs dark brown. 6. Same as the female (present specimen with antenna completely lost). Locality.

VIII. 1965 (Nr. 389), 1 Adialytus kaszabi sp. n. <j>. Head sparsely clothed with long elected hairs. Temple in dorsal view shorter than eye (2:3), weakly convergent behind eye; ocellar triangle apicaUy obtuse; face a little more than 1/2 as broad as head (9:17). Antenna with 12 segments; each flagella: segment with dense adpressed short hairs as well as a few long erected ones apically which &re less than breadth of segment, the 1st being 3 times as long as broad at base and longer than the 2nd (13:11). Mesoscutum moderately arched, falling vertically into pronotum, w :h scattering erected hairs along notaulus and on lateral side; notaulus distinct only on perper. ücular part. Propodeum (fig. 22) smooth and shining, with 2 distinct carinae extending from its posterior margin to spiracle. Petiole (fig. 20) smooth and shining, weakly rugose laterally, 2. 3 times as long as broad at spiracle, broadened towards apex. Ovipositor sheat i (fig. 30) as figured. Fore wing (fig. 23): stigma 2.8 times as long as broad, distinctly longer than metacarp (5:3); radius more than twice as long as breadth of stigma; 2nd intercubitus, cubitus and recurrent vein entirely effaced; marginal hairs much longer than ones on surface. Hind femur and tibia (fig. 24) with adpressed hairs. Head and thorax black; clypeus and mouth-parts dirty yellow. Antenna dark brown entirely. Abdomen dark brown; petiole on basal 1/2 and apical extream and suture between 2nd and 3rd tergites yeUowish brown. Wings hyaline; stigma and vei- s brown. Legs dark brown to brown. 6. Unknown. Locality. Zavchan aimak: Choit chunch, 26 km ONO vom See Telmen nuur, 2150 m, 13. VII. 1968 (Nr. 1104), 1 o (holotype). In general structure this species closely resembles Adialytus salicaphis (Fitch). Judging from Japanese material of salicaphis (Kyoto, 29. V. 1970, fron; Chaitophorus niger Mordvilko, Takada leg. ), kaszabi differs from salicaphis as follows: A. kaszabi (o) 1. Ocellar triangle apically obtuse. 2. Propodeum with 2 distinct carinae on posterior surface. 3. Petiole more strongly broadened towards posterior end than . n salicaphis. 4. Each flagellar segment of antenna with a few erected hairs only apically. 5. Hind femur and tibia covered with adpressed hairs. A. salicaphis (o) 1. Ocellar triangle apically a right angle. 2. Propodeum without any distinct carina. 3. Petiole weakly broadened towards posterior end. 4. Each flagellar segment of antenna with a few erected hairs both apically and basally. 5. Hind femur and tibia covered with erected hairs. Trioxys pappi sp. n. C/, Temple in dorsal view slightly divergent just behind eye; face 1/2. 3 as broad as head. Antenna with 11 segments; 1st flagellar segment 3 times as long as broad at base, slightly longer than the 2nd (8:7). Mesoscutum weakly arched, falling gently into pronotum.
