tending to form ill-defined, apparently anteriorly angulate transverse 
fasciae. Cilia deep fuscous, base whitish, a dark fuscous antemedian 
fascia, a whitish bar opposite each of the extremities of the transverse 
fascia. Hind wing dark fuscous, a broad transverse white band occupying 
less than the central third of wing, from 3 / 4 of the costa to the middle of 
the dorsum, with its upper edge irregularly undulate, with a dark fuscous 
semicircular or wedge-shaped incision in the middle, posterior edge 
acutely dentate on the veins; base of the wing paler fuscous, costal edge 
along the transverse band narrowly fuscous. Cilia dark fuscous, white on 
the dorsum along the base of the central fascia. 
Male genitalia strongly sclerotizcd. Tegumen dilated above, with the 
ventral edges denticulate. Uncus short, slender, curved. Gnathos blunt, 
porrect, a denticulate process at each side of its base. Yalva narrow, 
cucullus much narrowed, clavate, ending in an erect spike. Vinculum 
small. Anellus cylindrical. Aedoeagus moderately long, straight. Cornuti, 
a series of some 14 spikes and fine denticulations. (Slide no. 937 D, holo- 
type.) 
Ostium modified. Seventh sternite with a median denticulate furrow, 
edged laterally by strong dentations; ventrad of this furrow two erect 
horns with a dilated base; limen proper, a moderate transverse band. 
Ductus bursae with a moderate straight cestum, reaching 3 / 4 towards the 
bursa, lower half of ductus denticulate, forming a sac above the bursa 
copulatrix, which is spheroid, with a finely denticulate wall. Signum, an 
elongate, minutely denticulate flat sclerite. (Slide no. 938 D, allotype.) 
Rattan Camp, 1150 — 1200 m, February 4, 1939 (holotype, male), 
February 6, 1939 (allotype, female), February 8 — 16, 1939. Three males,
