Binodoxys mongolicus sp. n. (j>. Temple in dorsal view slightly convergent just behind eye; face 1/2. 5 as broad as head. Antenna with more than 6 segments (broken); 1st flagellar segment 4 times as long as broad at base, longer than the 2nd (8:7). Mesoscutum moderately arched, falling vertically into pronotum; propodeum smooth and shining, completely and distinctly areolated, with a pentagonal areola relatively narrow. Petiole (fig. 43) weakly rugose, 3. 5 times as long as broad at spiracle, distance between' 1st and 2nd lateral tubercles shorter than that between 2nd tubercle and posterior margin (2:3). Genitalia: anal prong (fig. 40a) almost straight, weakly curved upwards apically, with 4 long hairs on dorsal surface and 2 short dilated bristles at apex; ovipositor sheath (fig. 40b) as figured. Fore wing (fig. 41) with stigma 3.0 times as long as broad and radius 3. 3 times as long as breadth of stigma. Head and thorax dark brown; clypeus and mouth-parts yellow; face and propodeum brown. Antenna dark brown, a little paler than head; scape, pedicel and 1st flagellar segment yellowish. Abdomen brown; petiole, 2nd and following tergites basally and anal prong yellowish brown. Wings hyaline; stigma and veins dirty yellow. Legs dirty yellow, darker dorsally. é. Unknown. Locality. Central aimak: Zaisan im Geb. Bogdo ul, Ulan-Baator, 5 km S vom Zentrum, 1600 m, 11. VI. 1968 (Nr. 924), 1 £ (holotype). In the general structure this species resembles Binodoxys heraclei (Haliday). Judging from MACKAUER' s redescription (1959) and STARY'

s figure (197 6, fig. 89) of heraclei, the present species is easily distinguishable from heraclei by having the ovipositor sheath stouter and the anal prong with 2 dilated bristles apically.
