Hind wing evenly rounded; cell very short; vein 7 well before end of cell, at its origin vein 7 is sharply bent upwards, and the upper margin of the cell is bent downwards so that the angle is shaped like a tuning-fork ; discocellulars faint; vein 5 not traceable ; vein 3 from end of cell; vein 2 very much nearer to end of cell than to base of wing ; lower margin of cell slightly angled at vein 2. The above is the neuration of the male ; in the female vein 3 of the fore wing is slightly nearer to end of cell, and on the hind wing vein 7 arises at an acute angle with the upper margin of eell. Hind tibias slightly fringed and with two pairs of spurs. In most species the male is provided with a linear discal stigma on the fore wing, running obliquely from the origin of vein 3 almost to the inner margin. In those species in which there is no discal stigma, the neuration of both wings of the male agrees with that of the female. *beturia Hew sikkima, Moore. .. 1. .. 2. ... 3. .. 4. .. 6. .. 7. astigmata, Swinhoe . 8 9 10 . 11. 19 13. 14 Of the above species, astigmata, honorei, and masoni are without the discal stigma, and it is very short and inconspicuous in decorata. Similar differences in the neuration of the male and the female are found in the Asiatic genera Pithauria and Aeromachus, in both of which the male when it has no discal stigma agrees with the female in neuration, but when provided with a discal stigma differs from the female in the position of vein 3 of the fore wing and in the distortion of the bifurcation of vein 7 of the hind wing. Confined to Southern Asia and Japan. HALPE MOOREI, sp. nov. H. beturia auctorum, nee Hewitson. Above dark brown. Fore wing: male with seven transparent white spots-two in cell, sometimes united, three subapical, and two on disk; the female has an additional opaque white spot at the centre of submedian. Hind wing with the disk suffused with paler yellowish. Cilia : fore wing grey, chequered with brown at end of veins ; hind wing uniform greyish. Underside: fore wing with spots as above and with an additional row of six or seven submarginal greyish-white spots between the veins, running parallel to the outer margin ; costa, apex, and greater part of outer margin suffused with yellowish scales. Hind wing with a conspicuous transverse white band of spots extending across wing just beyond cell from outer angle as far as submedian, the spot immediately outside cell considerably the largest; a small whitish spot at end of cell, an incomplete sub-marginal row of whitish spots from anal angle, the two inner ones |
