very sharply contrasted and the pale area which separates the median band from the basal area is narrow, the 
latter area being extended by the inclusion of two strong subbasal lines; subterminal incomplete, punctiform.

P. mordax sp. n. (27 k). Expanse 22—26 mm. In general coloration, as well as the number and ap¬ 
proximately the position of the lines, the small and punctiform (in part well isolated) subterminal marks and 
the strength of the double fuscous line between basal patch and antemedian, suggestive of inconspicuaria, but 
very distinct. Palpus scarcely so long. Head and base of abdomen pale or whitish. Postmedian of forewing 
with less strong central projection outward, subterminal with conspicuous, though not very large, white spot 
on and behind the 3rd radial. Underside more strongly marked than in inconspicuaria , the. hindwing with strong 
broad postmedian and subterminal lines, the former markedly sinuous, a faint and slender line between them.

26. Genus: (Eii|>liyia Him. 
(See Vol. 4, p. 244; Suppl.-Yol. 4, p. 145; Vol. 16, p. 91.) 
Face generally with slight tuft below. Palpus shortish or moderate, rarely more elongate. Antenna of 
simple or very shortly ciliate. Abdomen not or scarcely crested. Wing-margins smooth or slightly w'aved; 
forewing with areole double; hindwing with discocellulars not biangulate. As at present classified, an extensive 
genus, largely Palaearctic and Indo-Australian; most of the South American species which have been placed 
here may probably be separable by characters of the palpus, etc.; but a few r North American are certianly con¬ 
generic with the European. Genotype: the European picata Hbn. 
E. variegata Moore (27 k). A moderately large species, the forewing dull greenish, the rather broad 
dark median band with its edges on the whole more irregular than in its nearest allies and marked, especially 
the distal edge, with somewhat conspicuous white dots or teeth at the veins. Hindwing predominantly grey, 
anteriorly somewhat relieved with whitish; a whitish subterminal indicated. Underside of forewing less, of 
hindwing more, strongly marked than upper. Antenna of shortly ciliated. Simla to Bhotan, the type from 
Sikkim. Single $$ from Chia-kou-ho (W. China) and Sultanpur seem to agres with it. 
E. viridis Warr. (27 k), treated by Hampson (possibly with justification) as a green form of scortea, has 
nearly always a more sharply defined line bounding the basal area, less jagged edges of the median band, with 
little or no white scaling, and less variegated distal area, the subterminal lunules less developed, as also the 
black marks which accompany them proximally and distally. Hindwing more brownish than in variegata and 
almost unicolorous. Underside also on the whole slightly more brownish than in variegata , both wings well 
marked, the less strong central projection of the postmedian line generally noticeable. Sikkim (type) and com¬ 
mon in the Kliasis, where it varies considerably in size, on the whole smaller than variegata. — ab. solida 
nov. is an occasional form, parallel to some which I have so named in other Larentiines; with the median band 
(sometimes also the basal) solidly darkened, the green areas on either side of it almost devoid of markings. 
Khasis; type in the British Museum. 
E. scortea Swinh. (27 k). Most of the above differentiation from variegata applies also here, but the 
ground-colour is brownish, the size and markings less variable, the median band on the whole broader, occasion¬ 
ally a little more resembling in its outline that of variegata. Described from the Khasis, where the S3 have 
been taken in great numbers; also known from Kulu and British Bhotan. I have a $ from Laukhaung, Upper 
Burma, which seems to belong here. 
E. obscura Butl. (= butleri Leech) (see Vol. 4, p. 252). Considerably smaller than the preceeding group, 
palpus shorter (reaching very little beyond face), antenna simple; antemedian line less curved. The name- 
typical form, based on a Yokohama $, besides being unusually large, is nearly unicolorous, the median band 
almost uniformly suffused, but such an aberration could occur anywhere. — ab. (form, princ.) subobscura Prout 
(Vol. 4, pi. 11 f, as obscura) is the usual Japanese form and is recorded also from Szechuan; median area of 
forewing lighter, etc. multilinea Hmps. (= multilineata Hmps.), described from the Nilgiris, is very variable, 
but probably a tenable race by the dark underside, though even this is occasionally closely approached by 
aberrations of fecunda. On an average rather smaller and with the upperside rather brighter, more varied and 
more strongly marked than in the name-typical race. S. India and Ceylon. — fecunda Swinh. (27 k). Also ex¬ 
tremely variable, perhaps almost a synonym of o. obscura, but generally rather greener, more strongly marked, 
with more black marking, often a black cell-dot. N. India, the type from the Khasis. 
E. nyctichroa Hmps. (27 k) is smaller and darker, more uniform, the postmedian much more sinuous in 
its anterior part, the subterminal scarcely widened at the tornus, etc. Besides the type from the Palnis, I 
know only a $ from Belgaum and another from Khandalla.
