however, safer representatives; discocellulars not biangulate, hairiness of underside of forewing rather slight. 
T. ingressa sp. n. (27 d) cannot, in the present state of our knowledge, be referred to any known species. inyressa. 
although it might, according to the relative value attached to the structural distinctions, be consided to represent 
either latifasciaria or cuprearia on Formosa. Hairiness of underside as slight as in the former; discocellulars 
biangulate as in the latter, or even more strongly. Scarcely larger than typical c. etesias, with'which it agrees 
very accurately in coloration (both wings) and in the markings of the forewing; antemedian line rather firm, 
not quite so oblique as in latifasciaria, cell-dot very small and weak, well outside the antemedian band. Arizan.

the colour of latifasciaria), antemedian line somewhat more sinuous, the space between this and subbasal not 
pale. Hindwing with dark posterior and distal shading rather heavy. Naga Hills (type $), in the Tring Museum; 
Kachin Hills, 2 much worn, in my collection. A larger <$, from Nanchuen, S. Szechuan, is remarkably like 
latifasciaria except in the discocellulars. 
T. tryphema Prout (= latifasciaria Prout, err. det.) (27 e) is considerably larger than latifasciaria, with tryphema. 
the special ridge of the underside well developed, tone different, the well-expressed lines more numerous, the 
antemedian series not angled subcostally. hindwing sharply marked in the anal region; only the non-biangulate 
discocellulars justified my mistake in mating it with latifasciaria type, of which at the time I did not know 
any true <$. Hpimaw Fort, 8000 feet, 2

Face-cone developed. Palpus moderate. Antenna simple. Wings ample; forewing with areole double, 
with a bladdery fovea at base of 2nd sub median; hindwing with abdominal margin elongate, 
discocellulars biangulate. Genotype: indistincta Btlr. Himalayas to China and Formosa.

good analysis of the forms which has yet been undertaken, treats it provisionally as a single species. Some of 
the forms may perhaps be geographical races, but if so, their separation is probably according to altitude, as 
3 are already recorded from Ta-tsien-lu. The name-typical form was described from Dharmsala and is assumed 
to embrace all those of the N. W. Himalayas and perhaps some others; in fact the specimen figured in Vol. 4, 
a $ in my own collection, conies from Tali, Yunnan. proximifascia Prout (27 e), founded on 9 $$ from the proximifas- 
Khasis, is on an average larger than the corresponding sex of i. indistincta , the fore wing slightly less dusky, 
its subbasal line strongly blackened, almost straight, the boundary-lines of the median area blackened at costa 
and especially at hindmargin, the antemedian at liindmargin oblique outward. Hindwing, except in distal 
area, paler than in the name-type. Since I have seen also the and find the distinctions constant, excepting 
the size, I am inclined to think it a separate species. — sinotibetaria Wehrli (Suppl.-Vol. 4, pi. 14 d) is the pre- sinotibetaria. 
vailing form at Ta-tsien-lu and occurs also at Ta-ho and some other localities on the Sino-Tibetan frontiers. 
Large, whitish, variegated, rather richly and brightly marked. — kunkalashana Wehrli (Suppl.-Vol. 4, pi. 14 d) kunkalasha- 
is the smallest and most delicate form. Forewing with the band-like markings dark and complete, somewhat na - 
recalling the Colostygia salicata of Europe; hindwing with the lines very weak or wanting. Kunkala-Shan. - 
micans Wehrli (Suppl.-Vol. 4, pi. 14 d). Nearly as small, but otherwise very dissimilar; forewing uniform glossy mica ns. 
yellowish-grey, the lines of the forewing nearly obsolete, even the black and the light vein-dots reduced, the 
only sharply black markings being 1 or 2 subapical spots, spots at hinder end of ante- and postmedian and 
at times a straight subbasal as in proximifascia, to which it perhaps belongs, hindwing very weakly marked, 
darkened distally. Canton (loc. typ.) and Central to West China. orphnina Wehrli (Suppl.-Vol. 4, pi. 14 d) orphnina. 
is similar in the scheme of markings to sinotibetaria, but it is a smaller d a r k e r g r e y form and is separable 
at a glance by the dark yellow-grey hindwing. It is said to be rather prevalent at Mupin, Siao-lu 
and Tchang-kou and to have occurred also at Ta-tsien-lu, etc. 
A. lividata Bastelb. (= opulens Prout (27 e). Easily distinguished from its congeners by its dark colour, lividata. 
the ground-colour of the forewing more slaty or leaden, the markings olive-brownish. Formosa.
