Ph. chlorochrota limps. (31 f). Underside similar to those of the amplicata group, the white apical chlorochrota. 
patch of forewing not very clear. Easily distinguishable above by the almost entire suppression of white markings 
on the forewing and by the green tint of the paler parts. Yatong, Tibet. Has also been taken at Darjiling. 
Ph. fulguritis Warr. (= keraria Swinh.) (31 g). White markings slender, but very characteristic, the fulguritis. 
postmedian sharply expressed, the antemedian with a very strong central projection, the apical dash slender, 
extending to the postmedian. Hindwing with a lunulate or dentate subterminal line. Nepal frontier to Bhotan, 
10 000 feet and upward; type from Sikkim, probably Tonglo; Swinhoe's pair ( keraria) are labelled Darjiling. 
Ph. penguionaria Oberth. (34 h) (Vol. 4, pi. 6 1). Less dark than fulguritis , the veins rather strongly penguio- 
marked with ochreous; of the lines, only the postmedian remains conspicuous and this follows a different 
course. Szechuan and Chinese Tibet; type from Ta-tsien-lu. 
Ph. prosenes sp. n. (31 f). In coloration (especially in the $ — the A is rather more suffused with blue- prosenes. 
grey) somewhat recalling palaearctica Stgr. and leeclii Alph., but not really near any known species; specialized 
scaling of grey, occupying (in addition to the narrow part proximal to 2nd median) the proximal half of cellule 
2 and a small proximal part of cellule 3, the pencil light, inconspicuous. Fore wing not quite so broad as in 
leechi\ basal patch small, markings between this and median band rather well developed; median band little- 
darkened ; cell-mark elongate; postmedian less irregular than in leeclii ; subterminal slender and dentate between 
5th subcostal and 3rd radial, punctiform posteriorly; a slight pale apical dash. Hindwing and underside very 
weakly marked, the latter with weak commencement of postmedian line on forewing. Tibet: Rongshar Valley, 
12 500 feet, 5 July 1921 (A. F. R. Wollaston, Everest expedition) a pair. 
Ph. undulosa Alph. (31 f) (Vol. 4, pi. 5 h) belongs to a chiefly Palaearctic group, with pale (but not undulosa. 
white, nor white-marked) forewing and restricted dark markings. In undulosa the subbasal band is w r ell darkened, 
but narrow, the antemedian also strongly darkened, the darkest part narrow, but with broad suffusions usually 
accompanying it proximally; postmedian slender, zigzag, arising from a dark costal spot. Type from Honton 
River (Potanin), the Szechuan specimens (Ta-tsien-lu. Kunkala-shan, etc.) apparently not differentiable from 
those of the Koko-nor district. 
Ph. multilinea Warr. (31 g). Forewing more warmly coloured, subbasal band red-brown, not black, multilinea. 
antemedian much less (in the type scarcely at all) outbent behind the cell-mark, postmedian costal spot also 
red-brown, more extended, hindwing considerably darker. Sikkim, apparently rare. 
Ph. rectilinearia Leech (Vol. 4, pi. 11 g). Very near multilinea, perhaps a subspecies. Subbasal band rectilinearia. 
connected by rufous shading vflth base, antemedian still straighter, perhaps blacker, postmedian costal spot 
reduced. Omei-shan (type), Tu-pa-ko (Mupin). 
Ph. pallifasciaria Leech (Vol. 4, pi. 5 k). Forewing with the markings more broken into lines, at least palli- 
proximally to the antemedian. Hindwing more variegated, with postmedian and subterminal indicated. Sze- fasciaria. 
chuan, founded on 2 9$ from Che-tau, 3500 in. Also occurs at Yatong, Tibet. 
Ph. dipegaea sp. n. (31 g). Probably related to undulosa and multilinea, but very distinct. Forewing dipegaea. 
less variegated, the median area not noticeably lighter than the distal, very slender white lines bounding the 
median area, that of the postmedian broadened anteriorly; basal patch not, or scarcely, developing a dark 
subbasal band, its pale distal boundary weak; antemedian stripe narrow, its proximal part blackish and 
almost straight, its distal edge slightly more sinuous; cell-dot minute; postmedian with rather stronger angu¬ 
larities than in undulosa and multilinea ; subterminal very ill-developed except at costa; oblique dark mark 
trom apex slight and irregular. Hindwing with the paler and darker parts very weakly differentiated. Makong- 
Yangtse Divide, E. of Tse-ku: Pei-ma-shah, 14 000 feet, 23 July 1922 (Prof. J. W. Gregory), 2 A<S in the 
British Museum. 
Ph. velutina Warr. (31 li) (Vol. 4, pi. 8 c, as vetulina). Easily known by the heavy black markings velutina. 
which bound (and often in some degree suffuse) the median area and shade the subterminal and by the long¬ 
itudinal black streak of the terminal area behind the 3rd radial. Szechuan, common, the type from Chertou. 
Ph. atromarginata Warr. (31 h). A much smaller species, with twice excurved antemedian, no s t r o n g a tro- 
projections of the postmedian and two small, obliquely placed black marks between apex and subterminal, marginaia. 
Hinding white, with the dark distal border narrow and developed in the posterior half only. Tonglo (type) 
and Chumbi Valley (Tibet). 
Ph. multiplicata Warr. (31 g). Hindwing pale buff, the distribution of the dark borders about as in multiplicata. 
amplicata A or some forms of miniosata. Coloration of forewing somewhat as in nubilata and apicinotaria. 
antemedian with a moderately strong central projection outwards. E. Java, common on Mount Ardjoeno.
