on top; spiracles long-oval, space behind them convex. Upper mesepimerum smooth. Legs of medium strength; spur of mid tibia fully half the maximum length of basitarsus, longer than breadth of tibia. Basal third of fore wing bare, line of hairs on ventral surface of costal cell broadly interrupted; ratio of marginal, postmarginal and stigmal veins as 32:22:20; stigmal vein fairly clavate; pubescence on disc sparse, becoming denser distally, marginal fringe short. Gaster long-oval, acuminate at apex (Text-fig. 9). Hypopygium reaching middle of gaster. Male: 1.0-1.24 mm. Head and thorax bright green and shinier than in female because of shallower reticulation; basal half of gaster pale yellow (sometimes narrowly infuscate at base), spical half green; antennae and legs except for metallic coxae pale yellow, funicle in middle slightly darker, clava except apex fuscous to black (Text-fig. 11). Fascia on fore wing present though weaker. Head in dorsal view hardly twice as broad as long, with smaller eyes than in female, consequently with distinct rounded temples about 0.25 the dorsal length of eye and malar space of relative length 17 compared with eye diameters of 27:23 (Text-fig. 10). Palpi small, normal. Legs normal. Gaster about as long as and slightly narrower than thorax, rather flat. Holotype 9: S.W.UKRAINE, Budaky-Primorsk S. W. of ODESSA, 4 .IX . 1963 (BOUCEK); deposited in the BMNH, London. Paratypes: UKRAINIAN S.S.R., with holotype, 59 and 66 (including allotype) (BOUŐEK). AZERBAIJAN S.S.R. : near Imishli, 13. IV. 1963, id (L.Rzaeva). Some paratypes deposited in the Természett.Muzeum, Budapest and in the Zoological Institute (Acad. Sc.), Leningrad. Biology. Host unknown. Specimens were collected on sandy beach with very sparse vegetation, probably on some Artemisia sp. In the recent key to most European species by Graham (1969:639-653) Mesopolobus szelenyii runs in the key to females to couplet 16 but does not fit any of the included species; the male ends similarly at couplet 18. The new species reminds one somewhat, at least by its one-banded fore wing, of Mesopolobus maculipennis (MERCET), collected from olive trees (MERCET, 1923:105-107; see also ROSEN, 1960:30-31), but in the Spanish species the wing macula is broadly suffused below base of the marginal vein, the pronotal collar is much broader, the male antennae including clava are yellow, etc. There are two more Palaearctic species which seem to be rather close to M. szelenyii . Both of them were collected on Tamarix in Kazakhstan and are being described by our colleague Miss Klarissa Dzhanokmen (USSR). I hav"e seen only the males and have figured part of the antenna of one of them (sp. A, Text-fig. 12). In this species the fore wing is immaculate. In the other species the wing has two brown bands but the antennae (though distorted in the specimen) seem to be more like those of M. szelenyii , except for the shortes and completely black clava. This article is published in honour of my distinguished friend Professor Dr. GUSZTÁV SZELÉNYI,of Budapest, on the occasion of his 70th anniversary.
