Szechuan and the adjacent part of Tibet. 
0. leucocypta Hmps. (26 e). Much smaller than duplicata, narrower-winged, the dark markings less icm-.ocypia. 
intense, the double band fused into a single large patch, which is extended to near the base (but ill-defined 
proximally), the divided white line outside the postmedian narrowed; cell-dot small, ringed with white. Cudda- 
pah: Horsleykhonda, 3500 feet, the type $ unique. 
0. fissiferata Walk. (= intermixta Walk.) (26 f) is the only known South Indian species with the un- 
mistakable Ortholitha habitus. Palpus rough beneath. Pectinations moderate. Wings glossy, postmedian of 
forewing shaped nearly as in some of the similaria group, sinus at the radials not very deep, apical dash and pro¬ 
ximal-subterminal shade developed. Both wings beneath with cell-dot and indistinct postmedian. Nilgiris, scarce.

0. propinguata Roll. (Suppl.-Vol. 4, pi. 7 i) may be regarded as the type of a very natural group, or propinguata. 
perhaps genus, consisting of broad-bancled, generally rather dark species with not very elongate costa of hind¬ 
wing, distal area of fore wing weakly marked, but very generally with very characteristic apical markings con¬ 
sisting of a short dash or triangle followed (somewhat more proximally) behind the 5th subcostal by a second 
one, which is occasionally, though seldom, confluent with the apical. Typical propinguata was described from 
Masuri and reaches Kashmir and Kumaon. epigrypa subsp. nov. (26 f). Apex of forewing appreciably more epigrypu. 
falcate, the characteristic apical dark marks obsolete; on the whole the median band is less dark, but this varies. 
Sikkim, the type from Darjiling in the Tring Museum. Perhaps this and some at least of the other “subspecies'

by its larger size and relatively broader wings; definitely browner (less dark), the postmedian line on an average 
with less strong central projection; apex intermediate in shape between the two preceding, the 2 black marks 
developed. Luzon. 
0. corioidea Bastelb. (26 f). In colour nearest superlata, apex more falcate, the two black marks wanting; corioidea. 
distinguishable at a glance from all the propinguata forms by the straight postmedian line of the forew ing.

0. dicaea Prout (Suppl.-Vol. 4. pi. 8 a) also has the postmedian straight or almost straight, but dicaea. 
the coloration and wing-shape of p. propinguata (or perhaps the forewing slightly broader still), the black marks 
in the apex developed. Szechuan. 
0. exacra Wehrli (Suppl.-Vol. 4, pi. 8 a) differs from dicaea in that the distal edge of the median band exacra. 
forms an outward angulation in the middle and that the distal area of the forewing is white in its proximal 
part, grey-brownish in its distal. Szechuan: Kunkala-shan; also a series from Tupako, near Mupin, 7400 feet 
(H. Stevens). 
0. extrastrenua Wehrli (Suppl.-Vol. 4. pi. 8 a) differs from both the preceding in the much narrower extrasirenua. 
distal area of the forewing. In colouring it nearly approaches exacra, of which it may be a local modification, 
but the postmedian line is only weakly curved outward, not angled. Founded on 3 $$ from Tse-ku. 
0. euthygramma Wehrli (Suppl.-Vol. 4, pi. 8 a) is very like on diminutive corioidea, notably on the euthygram- 
straight postmedian line of the forewing. Face with a projecting cones of scales; palpus a little longer than rn(U 
in most of the group. Distributed in China. Shanghai to Szechuan. 
0. latifusata Walk. (= latifuscata Walk, index, naemata Feld.) (26 g <$, $). Walker's type from “Hindo- latifusata. 
stan" and Felder's from Narkundah are both $ and this sex, in the name-typical race from the N. W. Hima¬ 
layas, is ut once recognizable by the sharply white distal area. There is, however, very pronounced sexual 
dimorphism in this race and the d has nearly the coloration of propinguata. The median band has not, however, 
the conspicuous blackening in its distal part, its central prong outward is a little more prominent and the white 
line beyond is double from the costa to the prong. Both sexes, however, show an important venational 
distinction which — if supported by biological characters — should justify its removal from Ortholitha: h ind- 
wing with discocellulars markedly biangulate. — indecisa Prout (Suppl.-Vol. 4, p. 79). indecisa. 
from Szechuan, has the distal area in the $ less clean white (more tinged with brownish), the prong of the post¬ 
median in both sexes considerably less strong, the white line beyond it single. Thus it more nearly approaches 
some forms of propinguata or even exacra, but the discocellulars (though somewhat less extreme) place it with 
latifusata. $ commonly very large.

Typified by the Palaearctic clavaria Haw., which, so far as I know, stands somewhat isolated, this 
genus has been again extended so as to receive a few other Palaearctic. several African and numerous Indo-
