Fore wings greyish white, suffused at base, along the costa and the hind margin, with dark smoky grey; the spots all elongated; the first 3 costal spots enlarged into quadrangular blotches. Between the discal and submarginal row of spots is a row of grey wedge-shaped blotches, ending on the inner margin with 2 larger contiguous darker grey blotches ; another and more suffused series of similar blotches before the hind margin ; fringes grey. Hind wings purer white; the intermediate series of grey blotches much reduced in intensity ; fringes white. Thorax and abdomen dark smoky grey, with 2 black spots on each segment; thorax, head, and base of fore wings tinged with dull ochreous olive. Underside like upper, but with less grey suffusion, except along costa and hind margin of fore wing, the latter of which is wholly dark grey. Expanse of wings 60 millim. Hab. Naga Hills. [I have only seen the type of this, which was taken by Doherty at about 6000 feet in Sept.-H. J. E.~] METABRAXAS REGULARIS, sp. n. 3 . Fore wings dull white, traversed except on the disk by a succession of series of brown-grey spots and blotches; basal patch consisting of 3 interrupted lines of grey blotches, tinged with dull ochreous, followed by a 4th still more interrupted ; cell-spot large, oval, leaden grey; followed by 6 sinuous series of grey blotches, more or less parallel to the hind margin; the 1st, 3rd, and 5th consisting of smaller, more detached spots, lying on the veins ; the 2nd, 4th, and 6th of larger, more confluent blotches, lying between the veins ; the 2nd forming a dark double spot on the inner margin. Hind wings whiter; the spots smaller; the 2nd series beyond the cell-spot absent. Underside like the upper. Head, thorax, and abdomen dull yellowish grey, with the usual spots black. Expanse of wings 74 millim. Hab. Naga Hills. ABRAXAS METAMORPHA, sp. n. 3. Wings white; fore wings with basal area yellow, more or less overrun with cinereous spots, followed at ^ of the wing by a brownish fascia of irregular width and shape, but generally apocopated below the median; a central irregular, brownish fascia, running nearly parallel to hind margin, composed of confusedly confluent spots, almost touching on the inner margin the sinuous submarginal fascia, along the centre of which can be traced for § of the distance from the inner margin a pale yellow line ; the submarginal band is recurved backwards just before the costa, and followed on the costa by an irregular-shaped, somewhat triangular blotch, which at times unites with it a row of round black spots along the extreme hind margin, the space between these and |
