molata and trusa; postmedian line, particularly of the hindwing underside, with a deeper curve inward between. 
Hampson notices a remarkable venational anomaly in so-called magnijicata, but inaccurately attributes it to 
the 3 only; the disco cellulars of the hindwing are somewhat, or even quite strongly, biangulate, though decidedly 
variable, and I suppose he compared with the anomalous albilinea and $$ of the very closely allied fumipennis, 
which he has sunk. The present species is also variable in wing-markings, although (judged from a far shorter 
series) less so than molata. The type is a large 3 with white patches in the median band, that which surrounds 
the cell-spot large. — ab. (?) albilinea Hmps., only known from the type $, is large, cleanly marked and as it 
has actually non-biangulate disco cellulars and shows a brown suffusion on the cell-mark of the forewing, which 
otherwise I have only noticed in the type 3 of fumipennis, it may have to be removed to that species notwith¬ 
standing that the hindwing seems too light. Median band broad, its pale patches reduced, greyer, its distal 
boundary-line clear white. — ab. subseparata Walk., founded on a rubbed 3> has the band more uniformly 
darkened than in the type, almost solid. Discocellulars of the hindwing strongly biangulate. — ab. inspurcata 
Walk, is a $, not very fresh, the brownish parts still greyer, the hindwing rather more dusky, but may be con¬ 
sidered as the corresponding $ to the preceding. Discocellulars similar. 
X. fumipennis Hmps. (25 f). Generally easy to distinguish by its dark colouring, very notable on the 
hindwing. Discocellulars not biangulate, 3 pectinations less long (about 6:8), antemedian of forewing less 
bent outward. Nilgiris. 
X. griseiviridis Hmps. ( = curcmnata Moore part., nec typ.) (25 f). Pectinations quite short, terminating 
in tufts of cilia. Hind wing and underside in both sexes dusky; forewing with outer lobe of median band longer 
than in molata. Fresh specimens show some olive-green admixture in basal and distal areas of forewing. The 
type form has a characteristic grey suffusion in the distal part of the median band. — ab. aequifasciata nov. 
has the median band uniformly darkened throughout. — Bhotan to Simla, the type of griseiviridis from Bhotan, 
that of aequifasciata from Darjiling. 
X. cybele Prout (25 f). Near griseiviridis but with the pectinations still shorter (less than diameter of 
shaft), the fascicles of cilia longer than themselves. Forewing with median band wholly dark, its proximal 
edge twice indented, as in formosicola , its distal almost as strongly produced behind the 3rd radial as in grisei¬ 
viridis. Hindwing rather more uniformly dusky than in formosicola. Formosa: Arizan. Not difficult to dist¬ 
inguish from the last-named bv its smaller size, more projecting postmedian and especially the subpectinate- 
fasciculate 3 antenna. 
X. curcmnata Moore (= placida Prout) (25 g). Moore mixed no less than 3 species under his curcumata, 
his “type” (holotype) being a Darjiling $ of the present species, his allotype a 3 of griseiviridis, while another 
$ of Ins original series belongs to formosicola. Much confusion has resulted and Hampson determined yet a 
fourth species as curcumata (see liampsoni). The true curcumata is rather large, the median band less broad 
than in the similar forms, with its distal lobe very slight, the hindwing largely glossy white; both wings beneath 
with the postmedian much less projecting than in liampsoni. Pectinations about as in liampsoni, secondary 
processes apparently more developed. Sikkim to N. E. Burma, the type from Bhotan. 
X. hampsoni Prout (= curcumata part., Hmps., err. det.) (25 g). Very similar to curcumata, on the 
whole smaller (33 mm), hindwing with more suffusion and markings, postmedian different (see above). Antennal 
pectinations a little longer than in griseiviridis (about ljA); slight secondary processes present, somewhat as 
in fluctuata L. (Vol. 4, p. 223). Simla (type) and Dalhousie. 
X. hyphagna Prout (25 g). Rather smaller than liampsoni and structurally quite distinct in that the 
3 pectinations, though slender, are rather long; palpus little over half as long again as diameter of eye. Hind- 
wing in the $ a little less clear than in the 3 (here figured). Java (type) and W. Sumatra. 
X. fissiferula sp. n. (25 g). Larger than hyphagna (3 fully as large as the largest $$ of that species), 
palpus and pectinations rather longer. Forewing with termen rather longer and more waved; median vein and 
its fork (to the end of the median area) ochreous, strikingly conspicuous; median band much broader than in 
hyphagna, its proximal edge with blunt indentation at each fold, its distal irregularly dentate but without any 
large projections. Hindwing much less pure white than in hyphagna, its proximal and posterior parts, with 
the tornus, having considerable smoky suffusion, on which some lines are traceable. W. Sumatra: Sungei 
Kumbang, Korintji, 4500 feet, April 1914 (Robinson and Kloss), only the type 3 known (Mus. Tring). 
X. hedyphaes Prout (25 g). Palpus nearly twice as long as diameter of eye. Antennal pectinations long. 
Forewing green, with the markings blackish; basal patch less oblique-edged than in the following, with a rather 
deep indentation on the median vein; median band constricted in the middle, its coloration variegated; distal 
area with some variegated patches on the green ground. Manusela, Central Ceram, 6000 feet. Great as is the 
variability of many Larentiinae, it does not seem feasible to regard this as an aberration of the following.
