L. dascia Turn. (= extensata Meyr., nec Walk.) (26 k). A small, dark-marked species with rather short 
palpus and with the hindwing less elongate costally than in the somewhat similar ones which follow. Pectinations 
of the $ rather long, continuing to very near the apex. New South Wales to South Australia; it is not stated 
which is the type locality. 
L. cheimatobiata Guen. (= petrodora Meyr., M. S., phrixopa Turn., M. S.) (26 k). Rather larger, palpus 
about equally short, pectinations a little longer. In addition to the relatively more elongate wings, easily dist¬ 
inguishable from dascia by its less dark colour and much less sinuate postmedian. Tasmania (type) and Victoria, 
ab. extensata Walk, is a rather small S', with narrowed median band. Tasmania. 
L. epicrossa Meyr. (26 k). Palpus long. Hindwing with apex even more pointed than in cheimatobiata. 
termen more sinuate, the white lines on the forewing standing out more sharply, a more complete and uniform 
band between the postmedian and the subterminal, etc. New South Wales and Tasmania. 
Lc aganopis Turn. Palpus in A 1, in $ iy 4 . Pectinations in A 5, extreme apex simple. Wings ochreous- 
whitish, markings pale grey, on forewing brownish tinged; forewing with basal patch very small, median band 
in anterior half broad, in posterior much narrower, on costa darkened, its proximal edge curved outward, its 
distal from % costa, with a slight bidentate central prominence, thence strongly oblique and dentate to middle 
of hindmargin, the indistinct subterminal with a slight proximal suffusion towards costa, terminal marks inter- 
neural, short, triangular or slender; hindwing rounded, with suffused median, postmedian and submarginal 
lines, terminal line as on forewing. Woodford, New South Wales, March and April. (Turner.) 
L. oribates Turn. A- Palpus IV 4 , antennal pectinations 6 . Forewing with apex pointed, termen longer 
than hindmargin, slightly oblique; whitish, with numerous fine fuscous oblique lines; costa irrorated; median 
band consisting of 3 or 4 close lines, the first nearly straight from midcosta to % hindmargin, the last from % 
costa to less than y> hindmargin, slightly excurved in middle; the succeeding line thickened by some small 
dots; beyond this a further group of 3 close, wavy lines; an oblique shade from apex; terminal line interrupted. 
Hindwing rounded, the lines repeated, but obsolete in costal area, which is whitish, in the A with an oval patch 
of specialized scales. Mount St. Bernard, Victoria, 1 A- (Turner.) 
13. Genus: Itislrisclfin Alph. 
(See Vol. 4, p. 165; Suppl.-Vol. 4, p. 79.) 
An Eastern Palaearctic genus, noticed here for the sake of its representatives in West China. It scarcely 
if at all differs from Larentia except in shape; the produced, or even almost pointed hindwing gives it a 
distinctive appearance. 
K. productaria Leech (Suppl.-Vol. 4, pi. 8 b). The unique type, a A from Ta-tsien-lu, has longer pect¬ 
inations than typical Kuldscha, the shape of the hindwing slightly less extreme, the texture of the wings perhaps 
somewhat more delicate; median band of forewing broader, less irregular in shape and much less sharply dif¬ 
ferentiated than that of the typical group, rows of white vein-spots developed on the adjacent areas. 
K. lakearia Oberth. (Vol. 4, pi. 6 c). Hindwing perhaps more rounded than even in productaria, coloration 
rather dark, median band of forewing distally not so deeply concave between the radials as in the genotype 
staudingeri (Vol. 4, pi. 7 e; Suppl.-Vol. 4, p. 79), but more so than in oberthuri. Szechuan, few examples yet 
known to me. 
K. oberthuri Alph. (Vol. 4, pi. 11 a). Two AS °f this fine Palaearctic Kuldscha. which was described 
from N. E. Tibet, were collected at Teng, Arun Valley, S. W. Tibet, 11 000 feet on the Everest expedition of 
1922. The determination of the Yatong $ (Vol. 4, p. 165) is still doubtful. 
K. loxobathra Prout (Suppl.-Vol. 4, pi. 8 g) dignitosa Prout (= lakearia Sterneck, nec Oberth.) (loc. cit.). 
Larger than typical loxobathra , from Amdo, on the whole more variegated, cell-dots well developed. From true 
lakearia it differs in its paler colour, median band less solid, postmedian line straighter anteriorly, hind wing 
more pointed. Szechuan, the type from Ta-tsien-lu.

14. Genus; Kyrtolitlist Stgr. 
(See Vol. 4, p. 157; Suppl.-Vol. 4, p. 72.) 
Differs from Kuldscha (with which probably it could be united) in the simple 3 antenna. Distribution 
similar. The genotype, obstinata Stgr., is Palaearctic. 
K. purpureotincta Sterneck (Suppl.-Vol. 4, pi. 7 d). Larger than the genotype. Palpus short. Antenna 
of the A with the joints projecting and furnished with short ciliation. Whitish grey with reddish irroration, the 
markings grey-brown mixed with red; median band sharply defined, parallel-sided, sinuous. Szechuan.
