K. sachalinensis Matsumura. The genotype, and the only species yet referred here. 31 mm; 1 T, sachalinen- 
24 mm. Fuscous, with obsolete darker markings; forewing with wavy antemedian, median and postmedian 
bands, the median incurved behind the cell; marginal band black, wavy and narrow; fringe with some testa¬ 
ceous scales at vein-ends; distal half of costa with a series of testaceous specks. Hindwing with large black 
cell-spot; markings nearly as on forewing but without antemedian band, the other two both described as me¬ 
dian. Underside dark greyish, the hindwing with cell-spot and an obsolete fuscous band, the forewing with 
the specks at outer half of costa as above; fringes nearly as above. Founded on a pair from Shimizu, S. Saghalien, 
collected in August. 
15. Genus: I*roMe|>sis Led. 
(see Vol. 4. p. 49; Vol. 16, p. 59). 
A good many additions and corrections have been made to this attractive genus, which, though evi¬ 
dently not Palaearctic in origin, is well represented in China. 
P. vulgaris Btlr. (= delphiaria Hmpsn ., nec Guen., attenuata Warr.) (Vol. 4, pi. 7 b). Inhabits, besides vulgaris. 
nearly the whole of India, Singapore, Tonkin, Hainan and South China and even reaches Szechuan. Our 
figure, from a Hong Kong <$, is recognizable, though the dark element in the median area is scarcely strong 
enough and the antennal pectinations somewhat too heavy; in reality the latter are rather slender and little 
over twice as long as the diameter of the shaft. 
P. albidior Warr. (= deliaria Swinh. part., nec Guen.) (4 f). I do not now regard this as a form of deli- albidior. 
aria Guen., which, in any case, is purely Indian (Ceylon to Bombay). A further correction has to be made in 
that the moth figured as deliaria (Vol. 4, pi. 5 a) is really delphiaria Guen., another non-Palaearctic Problepsis, 
belonging to the section Problepsiodes. P. albidior is known from India, China, S. Japan to Formosa and 
perhaps Borneo. 
P. paredra Prout (4 f). Pectinations very short (little longer than diameter of shaft); hind-tarsus short paredra. 
(perhaps scarcely 1 / 3 of tibia). Easily distinguishable from eucircota (Vol. 4, pi. 7 b) by the irregular shape of 
the discal ocelli. Szechuan and N. Yunnan. 
P. subreferta sp. n. (4f). Variable in size, from 34 to 51 mm. Pectinations rudimentary, even the few subreferta. 
longest ones definitely shorter than the diameter of the shaft. Hindtarsus short, well under y 2 tibia (less ex¬ 
treme than in paredra ), the 1st joint perhaps 5 times as long as its greatest thickness (in paredra only about 
3 times). Cell-marks darker than in paredra, more continuous, only a very little constricted at fold, the larger 
(anterior) patch without the definite outward bulge between 2nd radial and 1st median. Tse-ku, 4 o'A in the 
British Museum, unfortunately none in firstrate condition. No less than 5 Problepsis species, fairly similar but 
not difficult to discriminate ( crassinotata, eucircota, paredra, discophora and the new species), occur at Tse-ku 
(which has a scarcely Palaearctic fauna) and were mixed in one series in the Oberthur collection. 
P. discophora Fixsen (4 g) has been wrongly sunk to the following (Vol. 4. p. 50), or at any rate two discophora. 
species have been mixed. Although it is not absolutely certain that the present one is really the discophora of 
Fixsen it is so probable that it seems better to employ that name for it than to impose a new one. Expanse 
generally 42—-50 mm; post median of forewing generally thick at costa, otherwise obsolete or weak (i n superans 
obsolete at costa, otherwise present or indicated), but this distinction is not constant. The teeth (rudimentary 
pectinations) of the $ antenna still further reduced. Retinaculum of <$ whitish, or when that part of the under¬ 
side is suffused, smoky with it. Vertex in both species, as in plioebearia (Vol. 4, pi. 5 a), white (in most Problepsis 
black). Described from Corea, known from W. China, E. China and Japan. 
P. superans Btlr. (Vol. 4, pi. 5 a) is larger than the preceding (generally 58—62 mm), the ocellus of superans. 
forewing large, with strong black curve round it (except in front), the subterminal spots on an average more 
strongly biseriate than in fLrseni. Blotch of hindwing larger, with the metallic ocellus widening more strongly 
in its posterior half. Forewing beneath more strongly smoky proximally; retinaculum black posteriorly 
(this black spot not detected on any fitm&mi). Japan (loc. typ.), Ussuri, Corea and Central China. — summa summa. 
form. nov. is even larger (64—66 mm), the discal spots relatively rather larger, that of the hindwing with its 
posterior continuation (to the abdominal margin) less narrowed. China, Tibetan frontier: Tse-ku, 2 Per¬ 
haps a local race. 
P. crassinotata Prout (4g). Antenna of o' dentate-fasciculate. May be known at once by the charact- crassino- 
eristic projection from the ocellus of the hindwing on its proximal side. A Khasi species which has been freely tata 
taken also in W. China (Yunnan and Sze-chuan). 
16. Genus: Scopula SchranJc.
