K. avulsa Prout (Suppl.-Vol. 4, pi. 7 d). Near purpureotincta, but with the antennal joints less projecting, avulsa. 
ciliation minute. Forewing browner, more uniform, without red admixture; median band almost as narrow, 
its distal edge with small and irregular indentations at the veins; terminal line strengthened. Hindwing some¬ 
what less white than in purpureotincta. Ta-tsien-lu (type <$ and others), Chinese Tibet and probably Yatung. 
the poor $ mentioned in Vol. 4, p. 165 under Kuldscha oberthuri. 
K. pantophrica Prout (Suppl.-Vol. 4, pi. 7 e). Somewhat larger; antenna slightly intermediate towards pantophrica. 
that of purpureotincta. Forewing a trifle more elongate; band as narrow as in them, but much more regular, 
all the markings parallel with the termen, a conspicuous whitish area between the postmedian and the dark 
distal area. Hindwing somewhat more variegated with white than in avulsa. Only known to me from Ta-tsien-lu. 
15.''Genus: Colostygia Hbn. 
(See Suppl.-Vol. 4, p. 129.) 
The separation of this genus from Larentia (sens, str.), like that of Xanthorhoe from Ortholitha, was 
grounded on the requirements of the Palaearctic Larentiines and has been found unworkable, in the present 
state of our knowledge, for the other regions (compare Vol. 16, p. 88). In the interest of conformity, I am 
retaining it here for a few Indian and Chinese species which are believed to have close affinity with the Palaearctic. 
C. ustipennis Pimps. (Vol. 4, pi. 11 f), from Dharmsala, seems evidently related to albigirata (26 k), but ustipennis. 
differs in its reddish fawn-colour, broader and much more regularly formed median band and other details. 
C. albigirata Roll. (= signata Moore, thomasina Warr.) (26 k), to which were formerly sunk some more albigirata. 
definitely Palaearctic Colostygia (see Suppl.-Vol. 4, p. 129) belongs properly to North India, extending from 
Kashmir to Upper Burma. Easily known by the very irregular shape of the median band. Antennal pectinations 
rather long. Type locality: Masuri. 
C. jameza Butt. (Vol. 4, pi. 9 b, as albigirata), with the antennal pectinations only about half the length, jameza. 
belongs chiefly to Japan and Ussuri, but I have seen a few small Szechuan specimens which I suspect of belonging 
to it; irregularties of the postmedian much less profound. 
C. bellaria Leech (Vol. 4, pi. 7 k; Suppl.-Vol. 4, p. 135) has evidently originated from the anomalous bellaria. 
corydalaria- group of the Palaearctic Region; see Vol. 4, p. 232). White, with sharply black, white-marked 
distal borders; the borders, or at least that of the hindwing, are much narrowed as compared with other members 
of the group, while the other black bands (subbasal and median) are much broken or even altogether fragmentary. 
Szechuan (loc. typ.), Yunnan and Central China. 
C. pendearia Oberth. (= moupinata Ponj., phaiosata Stgr.) (26 k). This was first described from Ta- pendearia. 
tsien-lu and is very abundant in W. China. It is not demonstrated that the form phaiosata , from Koko-Nor, 
figured in Vol. 4 (pi. 8 1), differs geographically, but in case that should be so, we here figure a topotypical 
pendearia. Not a striking species, but easily known by its coloration and its parallel-sided median band. 
C. exceptata Sterneck (see Suppl.-Vol. 4, p. 135) is unknown to me and I only repeat that its expanse exceptata. 
is about 43 mm, its shape comparable to that of Oporinia dilutata (Vol. 4, pi. 9 f), colour violet-brown with 
white base, subterminal spots, central section of median area and rows of dots delimiting that area. Face smooth, 
with slight tuft; palpus and pectinations long. A from Ta-tsien-lu. 
16. Genus: Ceplialissa Meyr. 
Erected for the romewhat isolated siria Meyr., this was afterwards merged in Scotosia (!), i. e. Philereme 
Hbn., later in the comprehensive “Hydriomena”. It differs from the following in its small eye, relatively small 
and very heavily scaled palpus and the highly sinuous termen if the forewing; $ antennal ciliation minute. 
A possible connecting link is found in the Chilian Coenotephria pusilla Btlr. 
C. siria Meyr. (26 g). Easily known, apart from its structure, by its small size and bright orange hind- siria. 
wing and underside. Only recorded from Dunedin and near Invercargill; flies like a Chrysophanus among Carex 
in low-lying Kahikatea forest 
17. Genus: Coenotephria Prout. 
(See Suppl.-Vol. 4, p. 140.) 
This, at least as constituted at present, is probably not a strictly natural genus; but it is convenient 
as affording a provisional position for a number of species which resemble Larentia or Colostygia in nearly 
all the easily-used structural characters but have non-pectinate antennae. Systematists who reject genera
