Show 772 MR. A. G. BUTLER ON [Nov. 3, discocellular dot on the primaries, the position of the nebulous discal band on the secondaries, which is much further from the outer margin, and the paler and more delicate colouring on both surfaces. Its general aspect is that of T.friga (P. Z. S. 1876, pi. vi. fig. 5, 2 ) ; but, in addition to the absence of the discocellular dot, the wings are whiter, the oblique subapical band is narrower, more oblique than in the figure, bounded throughout with orange, the outer border is more acutely dentated and terminates in a small black spot; the internal streak extends from the base, is grey throughout; the spot on the disk of secondaries is continued as a streak tapering to the submedian vein, and the marginal border is replaced by six blackish spots : on the under surface it is quite different, being similar to, but much paler than, the female of T. eione. Expanse of wings 28-33 millim. Two females.-Thrupp. There is not the least doubt that many Lepidopterists who did not possess abundant material would have put down T. jamesi as the female of T. thruppii, overlooking the differences between the sexes of that species, and regarding them all as males ; yet there can be no question that it belongs to a different subgroup, the males of which invariably have a transverse blackish discal spot or dash upon the orange apical area, as in T. friga, $ (see figure in P. Z. S. 1876); whereas the females of the T.-daira group nearly resemble the males, both having the orange apical patch bounded internally by a black line, stripe, or band. 41. TERACOLUS PHILLIPSI, sp. n. (Plate XLVII. fig. 11.) Nearly allied to T. evarne. The male differing in its pure white colour, smaller and less brilliant orange apical patch, with much narrower sulphur-yellow edging, the very narrow black margin to the primaries, absence of marginal spots in the secondaries; primaries below white instead of sulphur-yellow, the apical patch sulphur-yellow, with pale pink inner edging instead of creamy ochraceous, and with three well-defined subapical brown dots in an oblique series : secondaries creamy white, shorter than in T. evarne, with only the costa slightly yellowish. The female differs above in its whiter colouring, much better-defined black markings, the subapical spots forming a continuous irregular stripe, the much smaller orange apical area, and the entirely different coloration of the under surface, which closely resembles that of T. eucharis 2 • Expanse of wings, $ 42 millim., § 40 millim. One male and three females.-Thrupp. Var. a. Smaller; the orange apical area of male narrower, with concave rather than convex inner edge, the black border reduced to a few apical marginal dots; under surface of primaries with the subapical dots reduced to two, and orange instead of brown ; the female altogether paler, with smaller black markings, the subapical spots separate as in T. evarne 2, the apical area only irrorated with orange, so that it appears to be flesh-coloured; the under surface altogether whiter (but occasionally with pinkish secondaries), |
