Gryonini from Mongolia (Hymenoptera, Scelionidae)* by G. MINEO, Palermo Abstract — New locality data for some Mongolian Gryonini are given with the description of two new species". Eremioscelio kaszabi sp. n. 9 > Gryon neglectum sp. n. 9 • The material on which author reports in this note has been collected in Mongolia, in different expedition between 1963-1968 by DR. Z. KASZAB (Budapest). Eremioscelio cydnoides PRIESNER, 1951 — Chövsgöl aimak: 3 km SW von Somon Burenchaan, 1650 m, 21. VL-16. VII. 1968 (Nr. 993), am See Tunamal nuur, 26 km WSW von Somon Scharga, 1950 m, 21. VI.-15. VII. 1968, Exp. DR. KASZAB, 2 Ex. — The first record of this species for Mongolia comes us from SZABÓ (1973). Eremioscelio kaszabi sp. n. 9 9. Black. Head and thorax du il. Antennae brown. Legs brownish. — Head from above 5 times wider than long (31 : 6.1), posteriorly concave, anteriorly convex, narrowed below. Occiput sharp. POL : OOL = 15.3 : 2.0. Eyes bare (at 20x5). Malar space shorter than longitudinal axis of the eye (10 : 12). Mandibles bidentate. Length ratio among antennái joints : 10.5 : 4 : 3 : 1.7 : 1.6 : 1.5 : 1.5 : 1.3 : 2.2 : 2.0 : 2.0 : 3.3. Club with four joints. Frontal impression broad but shallow with a weak carina as long as about scape. — Thorax wider than long (28 :25). — Fore wing with a stump of Sc, fumous, covered with dense and short hairs; only trace of marginal vein apparent as a darkening of wing membrane. Longest fringe in hind wing less than 1/4 of its greatest width; Sc fully sclerotized on proximal and distal part only. —-Abdomen longer than broad (43 : 38). 1

st abdominal tergite almost 5.5 times wider than long (38 : 7). 2

nd tergite 2.7 times broader than long (38 : 14); 3

rd about 4.8 times wider than long (35 : 7.5); 4

th about 7.3 times wider than long (33 : 4.5). — Head with a fine-grained sculpture all over and with same scattered, minute hairs on temples and below vertex. Cheeks and surface of frons, laterally antennái sockets, about half length of eye finely, fan-like striated. — Thorax with the same sculpture as of head. Propleura at posterior base coarsely striated; mesopleura transversely incised, striae interrupted at meson; metapleura anteriorly incised. — l

Bt abdominal tergite finely alveolate sculptured and striated except on both sides. 2

nJ tergite sculptured as preceding one (on both sides, cells very small) longitudinally rugulose (excluding both sides for a space almost as wide as an eye); central rugulae almost reaching 4/5 length of tergite; last 1/5 alutaceous, except at apex smooth and shiny; following tergites alutaceous in the middle: fore and hind borders smooth and shiny. — Length 1.5 mm. çf, host and biology unknown. Eremioscelio kaszabi sp. n. could be related to E. lamia KOZLOV, from which differs notably by the length of scape and rugulae on 2

nd tergite. Holotype 9
