It is interesting to note that whereas this species was obtained in June and July, T. farrinus and T. bimbura were caught in October and November ; at the same time we have a specimen of T. farrinus taken by Col. Swinhoe in July ; so that they cannot be regarded as seasonal forms, as seems to be the favourite plannow-a-days with many allied species. The brown colouring of the underside in T. bimbura sufficiently distinguishes it from any of its allies to prevent confusion. 73. IXIAS PYGM«A. Ixias pygmcea, Moore, P. Z. S. 1882, p. 254, pi. xii. fig. 1. d 2, Campbellpore, 1/th November aiid 13th December; $, Chittar Pahar, 1500 feet, 1st December, 1885. "Ixias, n. sp. allied to dharmsalce, apud Swinhoe. This Ixias is not uncommon near Campbellpore in November; almost all the males taken were caught in this neighbourhood ; whilst at Kala Dilli in the Chittar Pahar the females were very common and there were no males. The females were, almost without exception, taken on the same plant (Croton sp. ?), a plant with spikes of white labiate flowers and broadish dark green leaves. I have taken this species near Campbellpore in the bed of the Haro ; near Attock Bridge, Khairabad side, two females ; and at Kala Dilli in the Chittar Pahar, all females, very common."-/. TV. Y. The type of this species, from Kangra, is a dwarfed male ; a similar one is sent to us by Major Yerbury ; the regular size of the species, however, for both sexes is about 59 millim., so that /. pygmaa is a misnomer. The species is allied to /. moulmeinensis, but differs in the broad inner black border to the orange belt of the male and the bright sulphur-yellow of the female ; the absence of the heavy black bordering to the secondaries removes it from the neighbourhood of I. dharmsalai. 74. BELENOIS AURIGINEA, sp. n. 2 • Allied to B. taprobana, but differing in the whiter colour of the primaries on both surfaces, the almost total absence of the grey basal suffusion on these wings, tbe more oblique and rather narrower discocellular patch, the narrower external border divided by six indistinct pale spots, the abrupt narrowing of this border (so as to leave only a greyish border on the interno-median area) ; the secondaries, which are either cream-coloured or ochreous, have a much narrower border with zigzag inner edge and enclose four spots of the ground-colour, the grey veins are similar, but the discocellular vein is only partly blackened and the subapical bar uniting the subcostal branches is represented only by greyish scales; on the under surface the whole disk of primaries is white, and the black and brown markings are all much narrower than in B. taprobana, but |
