5. Monophadnus semiciiictus HARTTG, 1837— This very elongate species in most superficial characteristics (e.g. venation, sculpture) very closely resembles a small-sized, 6 mm long, Cladardis elongatula KL. It is the head whose shape is so strikingly different from that of C. elongatula and from those of the Monophadnus HTG. species. A description is given on certain superficial features not figured in detail in earlier papers. Head hemispherical, smooth throughout with large eyes and very short temples behind (viewed from above ratio for temple and eye as 8:18). Malar space short, about half diameter of front ocellus. Inner margin of eyes almost straight throughout, and the two weakly converging towards clypeus. Clypeus very small with an emargination on front margin. Anterior tentorial pits just below antennái sockets extraordinarily deep. Postgenal carina very short, scarcely distinguishable as a feature, at most about as long as diameter of front ocellus (very similar to that of C. elongatula). Supra-antennal pits large. Frontal area smooth, shining not separated from rest of head. Post-ocellar area marked off at each side by a deep pit just behind ocelli, in front extending into a shallow groove, towards the back pit nob reaching hind margin of head. Outer orbit smooth, shining, very unlike any other representatives of Monophadnus: with their distinct groove beset with coriaceous punctures. Antenna very short, ratio for antenna and costa of fore wing as 40:65. Front lobe ofmesonotum without a medial furrow. Mesopleuron and sternum uniformly clothed in proclinate, short hairs. Claws with long and erect inner tooth, and not simple as Enslin (1914) wrote. Coxa, trochanters and most of femora black, apex of femur, tibia and basitarsus light yellow, extreme apex of hind tibia and four apical joints of tarsi light brown. Apex of ^43 in fore wing upturned (as in elongatula), approximating Al about halfway up. Rest of features correspond to descriptions given in current handbooks. The short malar space, the lack of a distinct post-genal carina, the slender habitus, upturned apex .43 in the fore wing strongly suggest a close affinity with Cladardis BENS., though I do not think that the displayed superficial features are strong enough to support the erection of a new genus as BENSON (1954) suggested. The single Hungarian specimen comes from "Kőszeg 1938. V. 1. Dr. VISNYA; Euph. (orbia) cy. (parissias), coll. E. CSÍKI", 1 9- (HNHM). 6. Fenusa dohrni (TISCHBEIN, 1846) — A characteristic leaf-mining species of the tribe Fenusini. Very small, 3-3.5 mm long. Body entirely black, at most legs partly dirty yellow, especially front pair. As are the majority of the representatives of this tribe, it is too very elusive and rarely collected. Hungarian locality: "Csepel sz., máj 9", Csepel Island is part of Budapest todayThis specimen was wrongly identified by MOCSÁRY (1 897) and published as "Kaliosysphinga pumila KL." which nowadays is known as Fenusa pusilla LEP. (HNHM). 7. Tenthredo obesa (MOCSÁRY, 1880) sp. rev. (Figs. 1-2) Allantus obesus was described by MOCSÁRY (1880) from Bulgaria: "In AltoBalkan Bulgáriáé ab EDUARDO MERKL detectus ..." A few years later KONOW (1888) published a key for some species of Allantus and considered MOCSÁRY'S obesus only a variety of A. rossii PANZER, 1805. He gave no explanation concerning the suppresion of this taxon. True enough most of MOCSÁRY'S descriptions are based on colour differences, and only occasionally do we come across any structural features. In this case his "eapite pone oculos fortiter dilatato, antennis evidenter clavatis, corpore crasso, ..." would in fact apply to any of the bifasciata-s^ecies group of modern Tenthredo. His colour differences are distinct: "auch das fünfte und sechste Rückensegmente des Hinterleib gelb gerandet" (KONOW 1888, p. 214), which, of course, was thought to be insufficient by later authors, so much so that even MOCSÁRY (1897) himself accepted KONOW'S synonymization and listed his species as a variety of rossii only! On the other hand, the study of the holotype: "Balkan MERKL."; "Allantus obesus Mocs."; "Alto-Balkan Bulgáriáé E. MERKL"; "Holotypus Allantus obesus
