TERPNA. By L. B. Proixt. 
luteipes. T. luteipes Feld. (<$ = similis Moore) (5 c, d<U 8f $) differs from the rest of the group in being whitish, 
almost as in the subgenus Terpna, the costal region of the forewing interruptedly red-brown. Thorax beneath, 
with base of wings, yellowish, the forewing usually with a pink flush behind the cell, the dark submarginal 
subalba, band usually well developed. -— ab. subalba ab. nov. lacks the submarginal band beneath and may, I suspect, 
be a seasonal form. Type from the Khasis, in my collection. Felder’s type of luteipes, a is the only specimen 
from Cochin China yet known to me and the species has generally been known as similis Moore, N. India and 
ruficosta. Malay Peninsula. — ruficosta Hmpsn. is more brownish, at least in the the underside with the yellow more 
extended, the dark borders on an average broader, the forewing beneath with the cell-spot broader, the hindwing 
also with a large cell-spot beneath. South and Central India. Examples from Ceylon, however, revert towards 
enthusiastcs. the N. Indian form. — enthusiastes subsp. nov. has a complete red-brown subapical line on the forewing from 
costa to the terminal spot at the 2nd radial; underside with the pink on the forewing and the yellow on the 
hindwing still more extended than in ruficosta, the borders still broader, that of the forewing much mixed with 
red-brown anteriorly, the cell-spot remaining as in luteipes or reduced. Barisan Range, S.W. Sumatra, at 
2500 feet, type in coll. Joicey. On Mount Korintji, in the same distinct, at 5000 feet, and on Mount Gedeh 
(Java) at 4000 feet, a less extreme form occurs, while at high altitudes on Korintji (7300 feet) the species reverts 
to the form luteipes or may even incline to ab. subalba. 
costisiriga- T. costistrigaria Moore (5 d). Larger, pale green, with brown strigulation, costal markings less red, 
rxa • more irregular, cell-spots larger above, a bluegrey band-like shade outside the postmedian of the forewing. 
Sikkim. 
neonoma. T. neotioma Hmpsn. $ antenna pectinate. Further differs from erionoma in being lighter brown, 
subapical patch less white, first line firm, underside not white, distally not sharply dark-banded. Ceylon. 
erionoma. T. erionoma Swinh. (5c). Crown of head and front of thorax quite pale, the upperside otherwise rather 
dark, with terminal patch near apex and subterminal spots between the veins more sharply white than in 
most of the species. Forewing with a narrow shade outside the postmedian line, anteriorly green- or blue-grey, 
posteriorly marked with white. The white ground-colour beneath not pure, the subterminal bands rather 
variable in development. Described from the Khasis, but extending to N.W. India and reappearing on Ceylon. —- 
subnubigo- subnubigosa subsp. nov. is a rather larger, darker form from W. China, both wings beneath (especially the forewing) 
sa. with the pale parts much more suffused with grey. Omei-shan, type $ in Mus. Tring; Kwanhsien district, 
albicomiia- 16 August 1925, paratype in Hill Museum. — albicomitata subsp. nov. (8 g) has more extended white maculation 
ia - outside the postmedian of the forewing posteriorly, little of the dark irroration remaining except a narrow 
subterminal band between the 2nd median and the bindmargin. Underside with the subterminal bands some¬ 
times narrowed. S.W. Sumatra: Korintji, 2 in coll. Joicey, the type at 5000 feet altitude. Also a few 
examples from Selangor. 
calaurops. T. calaurops Front (8 g). Browner than erionoma, without the characteristic shades outside the 
postmedian line; terminal spot near apex less sharply white; subbasal and antemedian lines well separated. 
Postmedian line of hindwing with an angle outward on the 2nd subcostal vein. Distal bands beneath broad. 
Hongkong. 
taiwana. T. taiwana Wileman (8 g). Larger than erionoma, perhaps broader winged. Less dark, with less white 
markings, the first two lines of forewing about as in calaurops, the antemedian sometimes almost straight, 
the postmedian of the hindwing intermediate between those of erionoma and calaurops: Underside rather more 
suffused than in erionoma, the distal bands less sharply defined, brown rather than blackish, that of the fore wing 
curved (in erionoma almost straight-edged proximally). Formosa. 
funebrosa. T. funebrosa Warr. (5 cl). Rather larger than erionoma and with the distal margin of the forewing 
appreciably crenulate; still darker and more uniform, except for the subbasal band and subapical spot; sub- 
ienuilinea. terminal white dots minute. Distal bands beneath very broad. Khasis. — tenuilimea Warr. combines the 
coloration of erionoma with the markings and underside of typical funebrosa, but has the white subapical spot 
less sharp and shows a tendency on the forewing beneath to develop a longitudinal pink shade behind the cell 
and the 2nd median, which is only faint in funebrosa. Sumbawa (type), Borneo, Sumatra, etc. 
vigens. T. vigens Btlr. (8 g). This species and the following are nearly related, but vigens has a sharply 
defined subbasal line, followed immediately by a whitish band, lacks the two deep outward curves of the ante¬ 
median line, has the cell-mark sharply black and linear and the white terminal spot near the apex well developed. 
Both have the submarginal bands beneath narrower than in the allies. Typical vigens is from Darjiling, also 
ruficolora- from the Khasis. — ruficoloraria Warr. represents vigens on Borneo and is of a more reddish colour, generally 
ria - rather larger and has the dark borders beneath broader. It is known also from Penang and Sumatra.
