BUTLER ON N E W [Mar. 16, apical marginal red-brown patch of primaries restricted to apex ; apical third of wing dusky, whitish at costa; discal lines on all the wings very indistinct; central lines well marked. Expanse of wings 4 inches. N.E. India. Type, coll. F. Moore. In this species and the male of the preceding the most noticeable thing at first sight is the strongly marked blackish patch above the whitish anal nebula of secondaries ; in this species, owing to the paler colouring of all the wings, this character is more evident than in T. silhetensis. 46. TRIPTOGON MASSURENSIS, n. sp. Primaries of male paler than in any other species, of female similar in colour to T. silhetensis; apex very acute; fifth obtuse denticle of outer margin more prominent, and the wavy line with a wider curve than in any other species ; black spot small; apex dusky : secondaries dull reddish, as in T. javanica : underside of male as in T. dyras, but with the transverse lines more defined, the apical red-brown patch of primaries strongly marked, and the subapical area whitish ; the underside of the female almost as in T. silhetensis, but more dusky, the apical patch more restricted, the costal area of primaries duller, the central lines of secondaries straighter. Expanse of wings 3 3 inches 8 lines, $ 4 inches 3 lines. Massuri, N . W . Himalayas (Hutton). Type, coll. F. Moore. Nearly allied to the preceding. 47. TRIPTOGON FUSCESCENS, n. sp. <S 2 • Altogether browner than any of the preceding species ; the apical and basal areas of primaries more dusky ; all the transverse lines dark brown, well defined ; the discocellulars dark : secondaries duller than usual; the interno-median dark patch less conspicuous; the anal spots large in the male, small in the female : wings below brownish testaceous, all the transverse lines very strongly defined ; the male with the apex of primaries and the apical area (excepting at costa) greyish brown, the nervures crossing it and the external angle tawny ; the costa sordid white : secondaries rosy-tinted, with the external area beyond the discal lines uniformly tawny, slightly dusky at apex : the female below (as above) is very similar to that sex of T. massurensis, but paler, less reddish and more greyish. Expanse of wings cf 3 inches 8 lines, 2 4 inches 5 lines. Darjeeling. Type, coll. F. Moore. This and the six preceding it are doubtless all local representatives of T. dyras of Walker. 48. TRIPTOGON SPECTABILIS, n. sp. cf. Primaries lilacine grey, costal area red-brown, outer margin from costa to second median branch with a broad tapering chocolate-brown border bounded within by a pale pinky line; two very irregular brown-edged dark grey bands across basal half of wing, also several very indistinct brown liturae; discocellulars brown, a |
