Show whitish with fuscous markings (the specimens are not in good condition and they will be more recognisably described as fuscous with a sinuate creamy-white dorsal stripe); the paler colour, which is most noticeable on the dorsum, leaves the base at about one-third the wing-width descending obliquely to the fold, it is thence slightly sinuate upwards, thence descending it ascends triangularly, and again obscurely, thence occupying the terminal area of the wing (and perhaps irrorating the subcostal portion); there is a strong short black streak from the base to above the flexus, and along the dorsum are some irregular dark spots; above the pale dorsal portion of the wing the fuscous colouring becomes more concentrated, appearing as a length-streak from the base; originating from the costa are several transverse dark markings, the most distinct being a cloudy spot at about two-tliirds, below which is a cloudy patch at the end of the cell; there is a dark (somewhat triangular) spot at the apex and others along the costa and termen ; cilia greyish ochreous, with a cinereous dividing line near their base. Exp. al. 23 mm. Hindwings plumbeous ; cilia greyish fuscous, with a dark dividing-line near their base. Abdomen cinereous. Legs pale cinereous, tarsi blackish, with narrow whitish bands above. Type <5 . Hab. T ibet, Gyantse, 13,000 ft., vi. 1904 (H. J. Walton, Tibet Expedition 1905 : 172). Two specimens. Intermediate between senilella Zett. and annulatella Crt.; in size and coloration more nearly resembling the former, but in pattern more like the latter, from which it differs in the pale dorsal marking being less abruptly (less angularly) bent upward and being divided by a black length-streak from the base-these would appear to be good diagnostic characters, but the poor condition of the specimens makes the matter uncertain.

Forewings appearing greyish, but actually chalky-white with fuscous markings and irrorations; a basal patch terminated at about one-third by a darker sooty marginal line, which leaving the costa obliquely outward becomes concave and thence projects strongly along the fold, receding obliquely backward to the dorsum-this basal patch is slightly darker than the rest of the wing and contains some darker transverse markings; before two-thirds a somewhat similar dark fascia includes a chalky, transversely irrorated, band ; beyond this the wing is whiter in appearance, and on the costa are three distinct fuscous triangular spots separated by the white ground-colour and succeeded by a patch of a more creamy colour ; from the last dark marking 34* 1906.] ON THE LEPIDOPTERA OF THE TIBET COMMISSION. 497 |
