fuscous; sometimes a more distinct dark fuscous vertical streak from 
below subapical costal dot to termen above tornus, sinuate and narrowed 
below; upper part of this streak sometimes dilated so as to form a sub- 
triangular spot which is narrowly connected posteriorly with apical dot; 
sometimes cell posteriorly more suffused with tawny; a dark fuscous dot 
on upper angle of cell ; a curved narrow line along closing vein ; one-two 
small dots on upper edge of cell before its end. Cilia in both sexes dirty 
whitish-ochreous mixed with fuscous; basal third paler, blotched with 
dark fuscous; a faint interrupted subapical line around apex and along 
upper third of termen. Hind wing pale ochreous-greyish or fuscous- 
greyish, somewhat darker towards apex, with a bronze gloss; cilia pale 
ochreous-whitish, tinged bronze-greyish towards apex. 
Uncus bipartite, forming two short-haired horns. Socius large, hairy 
above, bristled below. Valva constricted at 3 / 4 , cucullus transversely 
ovate, edge thickened, with two teeth, sacculus moderately curved. 
Aedoeagus short, narrowed and pointed. Cornuti, a sheaf of inequal 
spines. Anellus strong (Slide No. 790 D, liolotype). 
Limen T-shaped, sides curved downward, stalk short. Cestum, a pair 
of small sclerotizations in upper half of ductus bursae, a plicate scleroti- 
zation at its base (Slide No. 791 D, allotype). 
Lake Habbema, 3250—3300 m, end July— end August, 1938 (holotype,

oblique. Light grey, densely irrorated and on costal third evenly suffused 
with dark fuscous-grey; lower two-tliirds of wing densely irrorated with 
dark fuscous, which irroration forms a cloudy elongate suffusion on 
middle of disc and an ill-defined inwardly oblique streak from dorsum 
before tornus to middle of disc beyond cell; base of fold suffused with 
black, costa beyond this very faintly transversely strigulated with 
blackish ; a narrow terminal streak of dark fuscous irroration. Cilia fuscous-
