MICROLEPIDOPTERA OF NEW GUINEA 
outwardly except in tornus, with a faint paler basal line. Hind wing 
whitish, touched with creamy-pink, not paler than fore wing, hardly 
becoming paler towards base, apex and termen with a suffused minute 
black marginal streak between veins 6 — 7, sometimes indistinct. Cilia 
whitish, with basal half around apex and along termen as far as vein 5 
dark leaden-grey, well-defined anteriorly, pale pink elsewhere. 
Limen moderately broad, membraneous, ill-defined, broadly convex, 
lateially strong and distinct: lateral emarginations oblique-angular, 
lateral projections broadly triangular, moderately long, curved below, 
lateral rods dilated, with inner edge concave. Colliculum moderate, cylin- 
drical. Cestum bi'oad, tortuous, terminal fold moderate. Signum moderate. 
Eighth tergite truncate (Slide No. 331 11 holotype). 
Moss Forest Camp, 2800 m, October 9 — November 5, 1938 (holotype). 
Two specimens. A very distinct species which can easily be distinguished 
from all others, except the following one, by black basal half of cilia. 
Chionothremma euxantha spec. nov. (figs. 59, 81, 82) 
ev^avdoq = very yellow 
d 16 mm, $ 17.5 mm. Head and thorax pale yellow. Palpus pale yellow, 
median segment mixed laterally with black except at apex, terminal 
segment black. Antenna black, dotted with white, scape pale yellow'. Legs 
pale orange-ochreous, anterior pair brighter, tarsi fuscous, ringed with 
pale ochreous. Fore wing broad, truncate, not dilated, costa obliquely 
curved along 2 / 5 , straight posteriorly, apex rounded, termen hardly 
sinuate, vertical. Bright orange-ochreous, slightly paler on basal fourth; 
a jet-black rather narrow terminal line from a pex almost to tornus, in 
apex somewhat dilated, its edge sligthly suffused, regularly concave. Cilia 
light orange-ochreous, basal 2 / s dark grey, paler towards base. Hind wing 
pale orange-ochreous, turning pale ochreous on basal half; a narrow black 
streak in apex and along upper third of termen, broadest in apex, its edge 
irregularly suffused and irrorated with ground colour. Cilia pale orange- 
ochreous, turning pale ochreous on lower part of termen and on dorsum, 
basal 2 / 5 around apex and along upper third of termen dark grey, paler 
towards base. 
Tegumen clavate, broad above. Uncus broad, somewhat narrow r ed above 
base, top rounded, slightly emarginate in middle. Socius, a narrow short 
series of bristles. Gnathos strong, short, strongly curved, hook long. 
Transtilla knob elongate, median projection long, slender. Peniculus 
rather long, conical. Anellus flattened, corrugated. Vinculum strong, sub- 
rectangular, dilated below. Valva broadly semiovate. Aedoeagus with 
very oblique, excavate top and a long point (Slide No. 313 D). 
Limen narrow, strong, broadly convex, lateral emarginations short, 
rounded, lateral projections short, triangular. Colliculum strong, moder- 
ately long, almost cylindrical. Cestum broad, tortuous, coiled once, with a 
median furrow, terminal fold short. Signum moderate (Slide No. 366 D).
