terminal line and brown fringe-spots present, nearly as in fuscimargo. Hind wing with 1st median well stalked. 
Kwanshien. See further the original description in Vol. 12, p. 124. 
H. nemoriata Stgr. (3 e). Not quite so small as euethes, pectinations of the <$ considerably longer, 
wing-margins more rounded, though the hindwing shows a (very slight) elbow at the 1st radial besides the 
moderately developed one at the 3rd; 1st median of hindwing connate. Abdomen with small red-brown spots, 
or rudimentary crests. Spots on fringes rather strong. Only known from the Ussuri district. See also Vol. 4, p. 31. 
H. tenuilinea Alph. (3 e). In structure similar to nemoriata but with the $ antenna pectinate to the 
apex, 1st median of hindwing separate. Larger, more vivid green, lines more dentate, cell-rings recalling 
detracta. Corea, apparently very rare. — See also Vol. 4, p. 31, Note. 
H. fuscimargo Prout (Vol. 12, pi. 14 c). This species, not hitherto recorded as Palaearctic, was received 
by Oberthhr from Siao-lou. The lines are formed nearly as in inconcinnaria, but the fuscous (really blackish 
with a slight admixture of reddish) cell-dots, terminal line and fringe-spots and traces of red vein-spots or 
dashes in the angles of the postmedian distinguish it. Antenna of $ not pectinate. 
H. periphanes sp. n. (3 e). Brighter and less bluish green than fuscimargo, palpus shorter (scarcely as 
long as diameter of eye), pectinations somewhat shorter, especially those of the inner series (in fuscimargo 
both series are at least twice diameter of shaft), cell-dots scarcely indicated (in dark-green), no red vein-spots, 
terminal line very slight, fringe-spots more reddish than in fuscimargo. Abdomen dorsally without reddish 
admixture. Tse-kou, type <$ in the British Museum; Siao-lou, a smaller in the Wehrli collection, which 
also contains a larger, weakly marked, somewhat more bluish green $ of the same or a closely similar species 
from Tay-Tou-Ho, 1897 (R. P. Dejean). 
H. cinctigutta sp. n. (3e). Smaller than antigone Prout (Vol. 12, p. 124), which it resembles in the 
pale-ringed cell-dots; brighter green, the forewing with costa less long and termen less oblique, the hindwing 
relatively broader, fringe cleaner, with the spots more sharply marked. (Antennae lost.) Hindtibia dilated. 
Underside paler green, with only the terminal line and fringe-spots. Ta-tsien-lu, type <§ in coll. Wehrli. 
H. acyra sp. n. (3 e). Distinguishable by its dull green colour (slightly greyer than the <: pois green” 
of Ridgway, recalling Gelasma or Hemithea ), the elongate, well tailed hindwing and the greyish, darker-spotted 
fringes. Face blackish; palpus moderate: pectinations moderately long. Markings extremely weak. Mt. Omei, 
4000—4500 feet, July and August, 4 the type in my collection. 
H. isommata sp. n. (3 f). Larger than detracta (Vol. 4, p. 31), hindwing rather more angled at 3rd 
radial (though still quite weakly), 3nd joint of palpus rather less short, antennal pectinations of the $ more 
rudimentary (in reality merely long teeth), only a few of the longest about as long as the diameter of the shaft, 
the white cell-ring of the hindwing small, about as that of forewing. Ta-tsien-lu, type $ in coll. Wehrli; Siao- 
lou, 2 $$ in the British Museum. 
H. ichinosawana Matsumura is a very small species (20 mm) with the antennal pectinations of the 
$ long, yellowish. Head brownish. Palpus very small. Wings pale green, unmarked; forewing above narrowly, 
beneath more broadly, yellowish on costa, fuscous at its base. Hindwing rounded. Ichinosawa, S. Saghalien, 
25 July 1925, only the type known. 
H. loxiaria Guen. (= dispartita Walk.) (Vol. 12, pi. 14 c). On the synonymy of this species, see Vol. 12, 
p. 123. To the brief description in Vol. 4, p. 31 (as dispartita) it should be added that the antenna of the $ 
is noticeably serrate, not (as in the following species) simple. Probably confined to the Punjab and Kashmir, 
the Sikkim efformata Warr. being a different species. — ab. cymaria Hmps. has the white cell-spots enlarged. 
H. fletcheri Prout (Vol. 12, pi. 14 c). On an average larger (28—35 mm), of a somewhat more bluish 
green, the cell-spots generally somewhat weaker or narrower. Gulmarg, Kashmir (8500 feet). — subcaerulea 
Prout is a small form (22— 27 mm), perhaps seasonal, of a much bluer colour. Common about Srinagar in 
August and September. 
H. malacliitaria Prout (Vol. 12, pi. 14 c). Colour of subcaerulea, $ antenna with shorter pectinations, 
hindleg perhaps more slender, apex of forewing less pointed, the white line weaker. Only the type known, 
the locality given as “Kukli, N. W. India”. 
H. christinaria Oberth. (1 e), founded on a unique <§ from Chinese Tibet, is distinguishable at a glance 
by the strongly angulated postmedian line; antemedian present on both wings. Face white, with reddish 
band on upper part, palpus scarcely reaching beyond frons, antenna pectinate to about 4 / 5 , hindtibia slightly 
thickened.

I. putata L. orientalis Wehrli (6 a). As intimated by Leech (see Vol. 4, p. 32), specimens from E. Asia 
are darker than the European. Fresh specimens, according to Wehrli, are more deeply coloured, clear grass-
