ATOPOPHYSA. By L. B. Prout. 173 
a very strongly differentiated form of that species; the discovery of the <$<$ may probably throw further light 
on the question. 
P. stevensi sp. n. (16 d). Expanse 23—28 mm. Antennal ciliation of the minute. Otherwise so ex- sievcnsi. 
tremely similar to mononyssa and so variable that constant distinctions can scarcely be found. Hindwing a 
trifle greyer (less brownish), above very uniform or with traces of cell-dot and postmedian, apparently never 
with conspicuous pale band outside the postmedian and subsequent darkening of distal area. Forewing 
with basal patch rather straight-edged, generally a little more obliquely than in mononyssa and separated by 
a broader green area from median band; the latter very generally (perhaps always, but many are very wasted) 
almost solidly dark; postmedian generally almost perpendicular from costa to the angle at 1st radial (in mono¬ 
nyssa, slightly more curved), its angle inward at the 2nd radial sharper, almost rectangular; outer area com¬ 
monly more weakly dark-marked (or at least much less than in pella ), sometimes almost clear green so as to 
recall the Formosan P. viridiplana Bastelb. Tu-pa-ko and neighbourhood (W. China), 7300 feet or above 
(H. Stevens, Kelley-Roosevelt expedition), 31 $3, 12 type in the Thing Museum. 
P. fumataria Leech (Vol. 4, pi. 7 h). In Vol. 4 (p. 260) it was suggested that this was “perhaps a Peri- fumataria. 
zoma” , but the facies and the abdominal crests (though they are not extra strong) leave little doubt it should 
be transferred here. $ antenna almost simple, the joints laterally compressed. 
P. bipartaria Leech (Vol. 4, pi. 7 k, p. 259, as Cidaria). Antenna of the dentate-ciliate in 8 small bipartaria. 
and very poor Tu-pa-ko which I refer here, though they may possibly be long-winged zoarces or a third 
species; Sterneck, who records 2 from Ta-tsien-lu, gives their antennae as “simple, only with minute 
pubescence”. As they have the “green” parts (perhaps better described, even in true bipartaria , as olive- 
yellow) “not greenish, but red-yellow”, there are evidently two different species before us, though the colour 
variation might be merely analogous to that of divergens. One $ of bipartaria has been sent me from Upper 
Burma. 
P. zoarces sp. n. (16 d). Colouring closely as in typical bipartaria , the dark vinaceous-grey parts a little zoarces. 
further darkened, more slaty. Smaller, the wings relatively a little shorter (termen of forewing not quite so 
oblique); forewing with subbasal dark patch a little less obsolescent, especially at costa; median band differ¬ 
ently shaped, its proximal edge much more sinuous, its distal less near the termen, not making the strong 
outward bend to the 1st radial but merely undulate and culminating in a rounded lobe between the 2nd radial 
and the 2nd median; the greenish costal mark outside it less sharply defined but somewhat longer, fading 
away at the “lobe”. Omei-shan, 4000—4500 feet, 11 July (type §) and Pehlinting, 6000 feet, 50 miles N. N. W. 
of Chengtu, July-August (paratype $); both in my collection, G. M. Franck leg. 
P. lypra sp. n. (16 d). Palpus rather long (at least twice diameter of eye), with projecting hair and lypra. 
hair-like scales above and beneath. Antenna of $ moniliform (lamellate and with the joints projecting laterally), 
rather closely ciliate. Areole double, the distal one large, the 1st subcostal from much before its end, 1st radial 
shortly stalked. Thorax and abdomen above blackish brown, head less extremely dark. Forewing with the 
area between basal and median band so strongly irrorated that the wing appears nearly unicolorous as far as 
the postmedian, which is shaped about as in mononyssa; distal area whitish, somewhat irrorated with brown- 
grey and with 3 subterminal patches, the costal one perhaps the best defined. Hindwing with discocellulars 
oblique, not biangulate, 2nd radial about central; dusky, but not quite so dark as in mononyssa pella; a distinct 
cell-dot and traces of curved postmedian line. Szechuan: Pehlinting, type <$ and allotype $, collected with 
pella , both in my collection; also 2 GG from Mt. Omei, July 1931, at 4000 and 7000 feet (G. M. Franck). 
64. Genus: Atopophysa Warr. 
(See Vol. 4, p. 267.) 
I have reversed the order of this genus and Venusia in order to avoid the unwarranted separation of 
the latter from the rest of its group. I have not personally made much further study of Atopophysa, but 
Dr. Wehrli has done much to elucidate the Chinese forms, though they scarcely seem to me, judged from a 
very long series from the Oberthur collection, to be fixed geographical races. 
A. indistincta Btlr. (Vol. 4, pi. 13 e). A further Indian locality is Kumaon. Wehrli shows that the indistincta. 
forms from W. China are extremely variable. — sinotibetaria Wehrli (14 d), treated as a subspecies, is the pre- sinotibetaria. 
vailing, but by no means the only form found at Ta-tsien-lu. Large, whitish, rather copiously and brightly 
marked, well variegated; hindwing white. Also at Ta-ho and some other localities. — kunkalashana Wehrli kunlcalasha- 
(14 d). The smallest and most delicate form, somewhat recalling, in the continuous dark bands of the fore- na - 
wing, a small Cidaria salicata. Hindwing with the lines very weak or wanting. Kunkala-shan, few specimens 
yet known. — micans Wehrli (14 d). Not much larger than the preceding but presenting the opposite extreme micans.
