Rh. haematozona Hmps. (15 d). A rare species, founded on 2 and 1 $ from Chumbi Valley (Sikkim), haemalozona. 
a pair more recently obtained from Yatung (Sikkim—Tibet). Not quite so falcate-winged as olivacea, the sub- 
terminal line sinuous but not punctiform, placed somewhat less near the termen, the hindwing above more 
weakly marked. The type form is further characterized by its red colour between the subterminal line and 
the termen of the forewing. — ab. aidela nov. lacks the terminal band, but the fringes remain rosy. One of the aidela. 
Chumbi <$S and a second $ (Tring Mus., ex coll. Elwes, probably from the same source) belong here. 
Rh. pelloniaria Guen. (= meonodes Prout, meonaria Hmps., nec Guen .) (Supp.-Vol. 4, pi. 4 a, as meo- pelloniaria. 
nodes). From an examination of Guenee's type, unfortunately not exactly localised, I judge that it is one 
of the brightest, least meonaria- like forms of the north-western race which I named meonodes (Supp.-Vol. 4, 
pi. 4 a), perhaps from Masuri. This race, when pale, can be confusingly similar to meonaria , except in the 
venation; generally smaller, the cell-dots better developed, a subterminal line present, at least beneath, 
khasiana Moore (15 d) is a brighter and unmistakable form, with broad, deep-rosy markings on the forewing Ichasiana. 
(including streak or suffusion near the base posteriorly) and copiously marked underside. Common in the Khasis, 
known also from Sikkim. 
Rh. stigmatica Butt. (= vinacearia part. Hmps., nec Moore) (15 d). Cell-dot of forewing sharply black, stigmatica. 
generally larger than in the allied species; 2nd line slender, sharply defined, without any duplicating line or 
shade distally, at most with a very faint, scarcely noticeable shade. Subterminal line on both wings sinuous. 
Underside slightly yellower, sharply marked. N. W. India, the type from Dharmsala; eastward it reaches 
Kumaon. 
Rh. similata Moore (15 d). Very similar to stigmatica, on an average rather smaller, apex of wing slightly similata. 
more acute, generally a little more yellowish or brownish; cell-dots not enlarged, that of hindwing often wanting, 
central line scarcely ever so sharp as in stigmatica, nearly always with a duplicating line or shade distally, ter¬ 
minal line slighter, fringe pale (in stigmatica with a more or less dark central line or shade). Described from 
the Khasis, but known from Sikkim to Burma. Probably stigmatica may prove a race of it, for I observe that 
at Muktesar the September stigmatica are typical, white those collected in April—May are smaller and mostly 
transitional towards similata. 
Rh. vinacearia Moore (15 d). The original specimen, a $ from "Bengal ’, which we now figure, has never vinacearia. 
been duplicated and remains somewhat enigmatical (see Vol. 4, p. 43). If stigmatica is not (as suggested above) 
the north-western race of similata , it may be that vinacearia (1867) and stigmatica (1889) belong together as 
races; in any case vinacearia and similata seem too dissimilar to be united. The generally larger size, more 
ochreous ground-colour and weak, reddish lines give it quite a distinctive appearance. Cell-dot of forewing 
rather stronger than in similata, but not enlarged as in stigmatica. 
Rh. bisinuata Warr. (= vinacearia Leech, nec Moore, sinensis Prout) (Supp.-Vol. 4, pi. 4 b) is probably bisinuata. 
not, as I first assumed, a race of either of the preceding but a good species, with more deeply sinuous outer 
line. The type, erroneously labelled “Japan ”, was almost certainly from W. China; the distribution is from 
Teng-yueli-Ting and Chinese Tibet to Chang Yang. — wilemani subsp. nov. is on an average large, with a more wilemani. 
grev-brown tone and more pronounced grey shade bordering the postmedian distally. Formosa: Rantaizan, 
4 <$<$, 2 £0; Arizan, 1 2; type in the British Museum. 
Rh. tremiscens Prout (Supp.-Vol. 4, pi. 4 b) is very similar to bisinuata but broader-winged, darker, tremiscens. 
the lines much finer and more tremulous, the median line sinuous. Nanehuen, S. Szechuan. 
2. Genus: Tanaotrielila Warr. 
(See Yol. 4, p. 44.) 
Antenna of the <$, as in Bhodostrophia , with two pairs of pectinations to each joint. Hindleg of the $ 
with a strong hair-pencil from femoro-tibial joint, proximal spurs wanting, one terminal spur strong, the other 
more or less completely atrophied; $ with 4 spurs. Venation and scheme of markings about as in Bhodostrophia, 
2nd subcostal of forewing arising from the cell. Genitalia ((J) similar in scheme but very distinct; "pseudo- 
mappa” (bilobed process of 8th sternite) almost terminal and there are in addition two masses of darkened 
chitin, separate from it; uncus very remarkable, strongly chitinous (in Bhodostrophia “fleshy”); inflated, truncate; 
aedoeagus long, narrow, curved (in most of the group shorter and stouter). Only a few' Himalayan and West 
Chinese species or races are yet known. 
T. prasonaria Swinh. (= prasonarius Hmps.) (15 e). The type of the genus and by far the best-known prasonaria. 
species, recognizable by its warm ground-colour and strongly darkened costal margin. Underside paler, especially
