so anteriorly, straight in middle; apex subacute, narrower in male; termen 
gently sinuate in male, hardly sinuate in female, moderately oblique. 
White, tinged isabel, markings jet-black. A moderate patch on base of 
costa, semiovate in male, triangular in female, reaching beyond upper 
edge of cell; a small outwardly oblique mark on T / 4 of dorsum, minute in 
male; a small wedge-shaped transverse mark on costa beyond 1 / 4 ; a rather 
large invert-triangular patch on middle of costa, to upper edge of cell, 
with top dilated, especially in female; this patch continued along cell 
posteriorly by a horizontal short streak, patch and streak together giving 
rise to a slightly oblique calix-shaped mark; an erect-dentiform, somewhat 
inwardly curved and oblique dot on 3 / 4 of costa, followed by a black point; 
sparse minute black scales scattered over disc, forming a somewhat denser 
group on lower edge of cell before middle of wing, a curved interrupted 
line along closing vein, and a less distinct series of black specks from 
dorsum before tornus to below costa beyond 3 / 4 ; this irroration, of minute 
black specks almost entirely obliterate in male; female with following 
additional markings: a narrow sinuate black line from end of vein 2 to 
end of vein 1), continuous as far as vein 6, interrupted so as to form three 
short transverse interneural strigulae above this vein, and marginal black 
points on veins 5 — 8. Cilia white, an antemedian row of black points, 
almost obliterate in male. Hind wing and cilia glossy white, in female 
apex and terminal edge somewhat transparent isabel-white. 
Tegumen short, deeply concave, subconical. Uncus very narrow, being 
a long projection with bulbate top. Hamus strong, moderately broad, 
sinuate, top concave, curved laterad. Socius represented by a group of 
fine bristles at base of hamus. Gnathos small, arms rectangularly bent 
downward in middle; top, a narrow transverse rod. Transtilla narrow, 
submembraneous. Valva narrowly ovate, costa slightly excavate in middle; 
cucullus obliquely rounded, top with a patch of strong pointed bristles; 
harpe an oblique, haired, and sparsely bristled fold; sacculus strong, 
sinuate, almost 1, ending in a pad with bifid bristles, preceded by a short 
acute projection. Aedoeagus strong, slender, rectangularly bent beyond 
middle, top bifid. Anellus long. (Slide No. 682 I), holotype). 
Genital segment sclerotized, swollen, almost spheroid. Limen formed 
by an elongate strong sinuate blade at each side, transversely oblique, 
ending in an excavate dilatation, which together surround a small ostium, 
right dilatation immediately continued into a very strong long colliculum. 
Ductus bursae extremely short. Bursa copulatrix small, spheroid. Ovipositor 
surrounded by a weak thickened collar; lobes rather narrow. (Slide 
No. 683 D, allotype). 
Top Camp, 2100 m, January 15, 1939 (holotype, male). Moss Forest 
Camp, five km northeast of Lake Habbema, 2800 m, October 15, 1938 
(allotype, female). One male, one female. Very distinct species, allied to 
S. octosticta Meyrick, 1930.
