Figs. 13-15. Head, anterior, $ : 13 = E. platamonense sp. n., 14 = E. lindae sp. n., 15 = E. pergandei ASHM. there is distinct reticulate-coriaceous microsculpture. — Gaster is as long as head and thorax together, tergite one as broad as long the remainder trans­verse, tergite one and two and the base of three strongly reticulate-coriaceous the remaining tergites less strongly sculptured. The hypopygium is about as broad as long, broadly but narrowly emarginate apically, not projecting beyond the sides of the gaster. Hypopygium (fig. 4) flat centrally, not folded, thick, with a slight transverse fold just before the apex, shining and moderately punctate with an apical fringe of short hairs — the longest in clumps on the lateral lobes. —• Colour black, labrum, mandibles and legs yellow, tegula, costa and pterostigma of the wing brown. rf. Same as female except that the antennae are longer and thicker the eyes smaller, the frons more heavily strigose and the first tergite of the gaster rugose. The colour is generally darker, the labrum black, mandibles and legs testaceous and somewhat infuscate. Holotype 9 : Mongolia, Bulgan aimak, 30 km NN VY von Somon Daschincilen, 1200 m, 15.

This species is extremely close to E. pergandei ASHM. and to E. luxemburgense WASM. It can be distinguished from both by the characteristics of the hypopygium given in the key to species. E. lindae is more strongly sculptured on the head and mesopleurae than either pergandei or luxemburgense. In most specimens of pergan­dei there is no trace of a transverse carina on the propodeum which is evenly roun­ded in profile. In those specimens of pergandei which have a transverse carina on the propodeum it is less strongly developed than in lindae and the propodeum in profile is not as sharply angled. The clypeus (Fig. 14) of lindae is more distinctly emarginate than that of pergandei which has an almost straight apical border. The face of lindae is slightly broader between the eyes than that of pergandei. Elasmosoma luxemburgense WASMANN Elasmosoma luxemburgense WASMANN, 1909: 168. 2 syntypes 9 Luxemburg : WASMANN, 29. 7. 07 (NHM) (examined). Syntype 9 Luxemburg: WASMANN July 1904 (NHM) (not examined). I have not been able to find the formal description of this species which WASMANN (1909: 168) evidently intended to publish. In this same paper (1909), however, there is sufficient information upon the species to validate the name according to the provisions
