RHODOSTROPHIA. By L. B. Prout. 
143 
Chiefly Palaearctic, the Indo-Australian species belonging for the most part to North-West and North 
India or to China. 
A. Section Rhodostrophia. Forewing with 2nd s u b costal arising from cell. 
Rh. cinerascens Moore (— subflavida Warr.) (Vol. 4, pi. 5 d), founded on a from Pir Panjal, W. Kashmir, cinerascen s. 
is the oldest name in a group which embraces also adauctata Stgr. (Vol. 4, pi. 3 d) and bicolor Warr. . and which 
evidently belongs to the Palaearctic more than to the properly Indian fauna. Warren’s type of subflavida comes 
also from W. Kashmir (Sonamarg) and the two have been accepted as synonymous, I think correctly. The $$ 
are smaller and narrower winged than the £$. The type form has the forewing ashy or greyish, but the colour 
varies to light brown and the strength of the markings is also subject to great variation. — ab. rufilinea Front, rufilinea. 
only known to me in the browner forms .has the postmedian line of the forewing reddish or parplish. sometimes 
diffused distally. — borealis Swinh. (15 b), from Masuri (?), Kulu (type locality) and E. Kashmir, seems to be borealis. 
on an average much more strongly marked, has the forewing brown, commonly with a purplish tinge costally, 
and the cell-dots distinct, but is variable and perhaps not really tenable as a subspecies. — ab. rhoda Prout rhoda. 
has the rosy suffusion much increased, the postmedian line reddened as in ab. rufilinea. The type $ and a 
very rosy $ were collected at Kokser. together with almost typical borealis. A nearly identical, or even 
brighter-lined aberration occurs in the Gurais Valley as an extreme development of c. cinerascens ab. rufilinea. 
Rh. bicolor Warr. (Supp.-Vol. 4, pi. 3 h, the forewing not shown nearly grey enough), differs from the bicolor. 
preceding in its appreciably more rounded wings, more diffuse and nearly always rosy postmedian line, and 
more denticulate subterminal, placed farther from the postmedian, on the hindwing running obliquely to near 
the tornus. N. W. India. — ab. suffusa Prout has the rosy suffusion extended over the entire forewing. Col- suffusa. 
lected with the type, of which Warren supposed it to be the ordinary $-form. 
Rh. poliaria Pimps. (Vol. 4, pi. 7 a). Distinguishable from strongly marked cinerascens by the bidentate poliaria. 
antemedian line of the forewing, the sinuous and dentate border of the postmedian band, etc.; both cell-spots 
very distinct. — ab. roseata Prout (lob) has the markings, the costal margin and the fringe of the forewing roseola. 
abovs and the entire underside strongly suffused with red. Both forms occur together in the Gurais Valley, 
Kashmir. 
Rh. plesiochora Prout (= pelloniaria Leech, nec Guen.) (Supp.-Vol. 4, pi. 3 i). Antennal pectinations of plesiochora. 
the <$ shorter than in meonaria (scarcely over twice the diameter of the shaft), wings shorter, particularly in 
the cJ, postmedian of forewing rather less oblique and more proximal, of hindwing broader. W. China (the type 
from Pu-tsu-fong, 9820 feet) and Chinese Tibet. Occasionally the 2nd subcostal of the forewing arises from the 
stalk of the 3rd—5th instead of from the cell, while every transition occurs. 
Rh. yunnanaria Oberth. (Supp.-Vol. 4, pi. 3 i). It has been found that this is very close to plesiochora. yunnanaria. 
perhaps merely an aberration of the same, perhaps a very rare species which occurs amongst it. In either case, 
it has not been matched in an extensive and somewhat variable series from the same locality (Tse-ku) and others 
in Chinese Tibet, all of which seem referable to plesiochora. Dr. Wehrli, who has very kindly lent me his 
material for study, points out that yunnanaria type (of which our copy, though not so excellent as Culot’s, 
gives a very good idea) shows a quite different antemedian, more approaching that of tristrigalis and that this 
and some other details suggest that a which he has recently received from Ningwuan and which certainly 
presents a different appearance from most plesiochora (markings and perhaps termen of fore wing slightly more 
oblique, colour somewhat less bright, the markings grey rather than rosy, cell-dot of forewing rather will deve¬ 
loped) may belong to the true yunnanaria . In some ways (including the stalking of the 2nd subcostal) this 
Ningwuan form rather approaches peregrina. The antemedian line, which would seem to give the best clues, 
is really very elusive, as it is generally extremely faint or obsolete, scarcely ever traceable to the costa. 
Rh. meonaria Gu,en. (= pelloniaria Warr. et Hmps., nec Guen.) (Vol. 4, pi. 7 a). Probably Guenee's type meonaria. 
c-ame from N. W. India, perhaps Masuri, although he only gives “N. India” as the locality; in any case chiefly 
known from Kashmir. The records for W. China belong to plesiochora. Larger than that, intermediate towards 
cinerascens, which it sometimes rather closely resembles; but its termen is slightly more oblique, even less convex 
posteriorly, its tone more ochreous brown, the costa of the fore wing generally, the fringes always pink, the 
oblique band (or at least the line) pink, the accompanying line not developed or, if present at all. very close 
to the principal line on the forewing and not dentate. 
Rh. glaucofusa Hmps. (Vol. 4, pi. 5 d). A narrow-winged, glossy species, recognizable by its pale glau- glaucofusa. 
cous-greyish tone; proximal markings obsolete, postmedian not very firm, parallel with the termen, accompanied 
distally by a white band. Quetta, only the type $ known.
