130 COMOSTOLA. By L. B. Prout. 
with a dark costal mark on the forewing. It is the type of the genus and has the discocellulars very characteristi¬ 
cally formed. 
C. demeritaria Prout (14 i), which was long confounded with laesaria and meritaria, is similar in colour 
to the former, or slightly more bluish, but less small, the costal margin of the forewing without dark spots to 
mark the beginnings of the lines. Distinguished from both by the somewhat narrower wings (shaped more 
as in mundata), less characteristic discocellulars and smaller cell-spots. Khasis. — vapida subsp. (?) nov., founded 
on a d from Mount Korintji, W. Sumatra, 7300 feet (Pratt brothers), is larger (24 mm), slightly broader- 
winged, the cream-coloured ante-and postmedian lines not edged with red. A $ taken with it measures 22 mm 
and the 3rd joint of its palpus looks a trifle longer than in typical demeritaria 9 - 
C. meritaria Walk. (14 i). Larger than laesaria, the cell-spots dark, shaped somewhat as in nympha 
(Suppl. 4, Taf. 3f) the rows of dots much slighter than in laesaria, no dark postmedian costal spot on forewing, 
the dark terminal line slender, but scarcely interrupted. The bluer colour, less narrow wings, etc., differen¬ 
tiate it readily from mundata. Ceylon (the type), with probable races in Assam, Borneo and Sambawa. 
C. francki sp. n. (Suppl. 4, pi. 3 f). Probably near demeritaria ( 1 4 i). Palpus in both sexes with terminal 
joint appreciably longer (in 9 about as long as diameter of eye); pectinations of $ somewhat less long; both 
wings appreciably broader, the margins of the forewing (or at least the costal) slightly more curved; colouring 
the same, the red and black scaling between the ground-colour and the cream-buff costal and distal edges less 
strongly developed; hindwing with cell-ring rounder, postmedian line more strongly outbent, generally nearer 
to termen at the bend than to the cell-ring (in demeritaria vice versa). W. China: Kwanhsien (M. Franck), type 
in my collection. Distinguishable from subtiliaria by its shorter pectinations, somewhat shorter 3rd joint of 
palpus, white lower part of face, etc. 
C. nereidaria Snell. (= flavicincta Warr.) (12 c). Distinguishable by its broader wings (the distal margin 
of the forewing more rounded than in the allies) and especially by the large and curiously angular cell-spots. 
Hindtibia of $ without the hair-pencil and terminal process of laesaria. Described from Celebes, but known 
from Borneo and the Malay Peninsula and extending eastward to New Guinea and the D’Entrecasteaux, Loui- 
siades, Bismarcks and Solomons. — levata Prout, from St. Matthias and Squally Islands, belongs here by wing- 
shape, broadly yellow costal margin, etc., but is less blue and has smaller cell-marks. 
C. orestias sp. n. (14 k). <$ 24 — 25 mm, 9 28 mm. Exceedingly like a giant nereidaria (the largest nerei¬ 
daria known to me, a 9, expands 22 mm). Palpus of 9 less extremely long. Face whitish in lower half (in nerei¬ 
daria red almost throughout ). Forewing with 2nd discocelhdar parting from subcostal at % cell-length or beyond 
(in nereidaria at about the middle); costal edge mixed with the same dark colour as the terminal line. Hindwing 
with the angle at the 3rd radial rather more noticeable. Kinabalu (Waterstradt), the type series of 4 and 
2 99 in the British Museum. A few $9 also known from Penang and Bukit Kutu (Selangor). — anicana subsp. 
nov., of which I known only 99 (26 — 28 mm), is a trifle rounder-winged (at least at the apices), slightly more 
bluish green, the cell-spot of the forewing not quite so large, the postmedian spots with somewhat less of the 
red scaling. Oetakwa River, Snow Mountains, Dutch New Guinea, 3 9? in the Tring Museum. — ab. (?) ectenes 
nov. is a further development of anicana, with slightly more rounded hindwing and the cell-spot of the fore¬ 
wing produced outward into a long triangle. Ekeikei, 1500 feet, British New Guinea, type 9 in British Museum. 
2 9$ from Mount Kunupi, 6000 feet (Weyland Mountains, Dutch New Guinea) are closely similar but — at 
least in one example — with the cell-spot not quite so extremely developed. 
C. iodioides T. P. Luc. {== eucraspeda Turn.) (14 k) introduces the second group of the genus (subgen. 
Leticodesmia Warr.) with strongly rounded hindwings and a different scheme of pattern. In iodioides the 
prongs which project from the reddish borders are very distinctive. Terminal joint of 9 palpus almost as long 
as 2nd (Turner gives but his description otherwise fits so well with iodioides, of which we figure the 
type, that I do not query the synonymy). A rare species; I only know of the two 9 types, respectively 
from Dawson and Port Darwin. — storthyngica subsp. (? sp.) nov. (14 k). A little larger, the reddish parts 
brighter, especially the face and termen, the midterminal prongs larger, an additional one present at hind- 
margin of forewing. Doerian, Riou Archipelago (Hammerman), 2 9 ?> the type in coll. Prout. 
C. callista West (14 k), founded on a 9 from Mindanao, is very likely another form of the preceding. 
Discocellulars of forewing characteristic, of hindwing unusually oblique. Distal borders broader than in iodioides 
and storthyngica, not so bright as in the latter, round the apex of the forewing with pronounced white proximal 
edging which somewhat recalls that, of cedilla (14k). 
C. dispansa Walk. (14 k). Closely similar to chlorargyra but with the abdomen green, the discocellulars 
not very characteristic, the 1st subcostal of the fore wing arising from the cell. Yellower green, the borders 
narrower, streak from costa interrupted. Ceylon, only a few examples known.
