Synanthedon apuieri (Fuchs, 1908) - gr. Distinction of forms S. spuleri and S. schwärzt (Králicek and Povolny) based on morphology is mostly impossible. In comparison with S. tipuliformis (Clerck), the yellow colouring of the two species is somewhat richer, the external transparent area is wider and convex in the outer margin (while altogether straight in S. tipuliformis ), the spots in the fore wing apical area not so notable or are absent, the anal tuft is with yellow hairs occalionally . So far, S. spuleri is known from Germany, Austria (SPULER 1910), Spain (BUSTILLO and VARELA 1981), France (LERAUT 1980), Yugoslavia (DANIEL 1964) and Czechoslovakia. The larva lives in galls on Juniperus. S. schwarz! described from Czechoslovak territory (KRÁLICEK and POVOLNY 1977) is trophically tied with Carpinus, Corylus and perhaps with other wood species. New for Hungary! Material: Kaposvár 1? , Igt. PAZSICZKY, coll. HNHM. Bembecia albanensis (Rebel, 1918) So far not distinguished from B. Ichneumoniformis (Denis and Schiffermüller), or considered as its variable specimens. It differs from the latter by the very small, largely scale-covered transparent areas of the fore wing (Figs 3,4). Female genitalia see Fig. 19. The bionomics and ecological requirements are still unknown. New for Hungary! Examined material: VIl/21. 1J (without locality), coll. ULBRICH; Szécsény, 1 o 7. VII. 1947., Igt. LIPTHAY, coll. LIPTHAY (HNHM). Chamaesphecia similis Lastuvka, 1983 A species earlier not distinguished from Ch. annellata (Zeller), or Ch. oxybeliformis (HerrichSchaffer). Somewhat larger than Ch. annellata , with the fore wing external transparent area in the male nearly rounded (elongate oval in Ch. annellata ) (Figs 5,6). The female can in some cases be reliably distinguished only by examination of the genitalia (LASTUVKA 1983 b; 1984; Figs 13,14). Ch. similis is at present known from Czechoslovakia (LASTUVKA 1983 b), Austria (STERZL 1967; as Ch. oxybeliformis ), Yugoslavia and Bulgaria (SPATENKA private communication). The larva lives for 2 years in the root of St achy s recta. New for Hungary! Examined material: Budapest, 9. VII. 1941 1 o*, 28. VI. 1942 If, Igt. SZOCS, 1 o, (without date), Igt.

Chamaesphecia colpiformis (Staudinger, 1856) Pontomediterranean species confined in its occurrence to xerothermic biotopes with Salvia nemorosa stands, which Is its most frequent host plant. KOVÁCS (1953) quotes a single locality from Hungary. With regard to possible confusion with related species the entire material deposited in the HNHM is presented. Most specimens were among the undetermined material (Figs 15, 16). Examined material: Budaörs 6. Vn. 1947 1 o*', Igt. ISSEKUTZ; Inota, 2. Vn. 1968 1 o* ', Igt. NYIRŐ; Magyaróvár, 29.

Chamaesphecia tenthrediniformis (Denis and Schiffermüller, 1775) A species till recent time not distinguished from Ch. empi forrni s (Esper) (NAUMANN and SCHROEDER 1980). We still lack a more comprehensive idea of its distribution, likely corresponds to the area of the host plant Euphorbia esula. Compared with Ch. emplformis , it emerges rather earlier, the main period of occurrence is in May and the first half on June. It occurs often in masses. Habitual distinction from Ch. emplformis is sometimes almost impossible especially in the case of single catches. Ch. tenthrediniformis is somewhat smaller, most specimens have wider fore wings, more slender abdomen and a rather distinct shape of the external transparent area (Figs 7, 8). Genitalia are illustrated in Figs 17 and 18. For these reasons only the unambiguously determined material is presented. New for Hungary ! Examined material: Budapest 24 d*'12 », Igt.
