paler. The underside of the fore wing differs in syriaca in the light stripe along the termen being wider, and recurving in the apical area toward the costa where it may extend down to the base and thus separating the black edge of the costa from the grey colour of the inner area of the wing. The new species is well delimited also from Brachionycha sphinx. The basic colour of sphinx shows an olive hue, that of the new species is pure grey. The former has a more extensive pattern, the frames of the orbicular and reniform spots are more or less well discernible, the same as the beginnings of the transversal lines below the costa, the black plical line bisects the median field, and another line, curving outwards, begins at about the middle of the basal line and extends usually to the middle of the wing. It is also characteristic of sphinx that the lowest white spot of the subterminal widens in the fold, becoming rather sagittiform whose branches might, at a smaller or greater rate, occasionally coalesce. The light marginal zone on the underside of the fore wing is narrower, more densely irrorated, hence less sharply delimited from the inner area. Its labial palps are also more densely hairy, almost shaggy. In the male genital organ of syriaca, the valvae are longer, their apices less expanding, without a conspicuous constriction in their middle. The base of the pulvillus is short, but the pulvillus is high and convex. The sacculus is long, acicular, apically slightly recurving. The aedoeagus is widely different, inasmuch as it is longer in syriaca, hardly constricted medially, and with a large, single thorn, aside of the batch of fine, spiniform cornuti. The genital organ of sphinx differs so much from both of the above ones that it seems to belong to a special subgroup within the genus. I introduce the new species by the name Brachionycha decipulae sp.n. into literature (decipula = a lure functioning like a trap; all known specimens had namely been captured by light traps). Holotype male: "Makkoshotyka, 1962 X. 30, light trap", in the light trap collection of L. KOVÁCS, Hungarian Natural History Museum. Paratypes: Makkoshotyka: 18, 26, 27, 28, Oct., 3, 4, Nov., 1962; 24, 30 Oct., 1 Nov., 1963, 10 çf, light trap, in the light trap collection of L. KOVÁCS, Hungarian Natural History Museum; — 28 Oct., 1964, 1 çf, light trap, in the collection of the Hungarian Natural History Museum. Female unknown. On 22 October, 1963, and 6 November, 1964, also the light trap in vargesztes (Mts. Vértes) captured two similar Brachionycha males, whose alar expanse, however, is very large (39, respectively 40 mm), their basic colour a darker, fumous grey suppressing the (perceptibly entire) pattern. Any nearer investigation must await the arrival of further material. References: 1. ABAFI-AIGNER, L. : Magyarország lepkéi (Budapest, 1907, pp. VI -fXXXII -f 137 + T 51). — 2.
