MICROLEPIDOPTERA OF NEW GUINEA 
oblique transverse band from 3 / 5 of costa to dorsum before middle of wing, 
formed by three interconnected rather irregular subquadrate spots, down- 
ward becoming smaller in size; a rather irregular marginal streak from 
costa before apex, around apex and along termen to tornus, its tornal 
extremity continued as an attenuated short slender subdorsal streak to 
about 2 / 3 of wing length; some scattered pale brownish -fuscous scales in 
middle of disc before fascia, denser and occupying entire breadth of wing 
beyond it, both tending to form longitudinal strigulation. Cilia pale 
straw-colour. Hind wing pale golden-fuscous, cilia pale straw-colour. 
Lobes of uncus broad, gradually rounded. Valva narrow, short, cucullus 
long, curved, slightly clavate, 1 '/ 2 x as long as disc of valva; sacculus 
over 1 / 2 , with a short, curved hook; harpe short, strongly raised. Saccus 
erect-triangular, long. Anellns strong. Aedoeagus moderately long. (Slide 
no. 1091 D, type.) 
Scree Valley Camp, 3800 m, September 19, 1938. Two specimens.

cJ 22 — 23 mm. Head shining ochreons-white, a smooth flap of scales 
over vertex and face, no fillet. Antenna pale ochreous, scape elongate, 
ochreous-whitish above, fuscous below. Palpus moderately long, glossy 
pale ochreous, median segment dark fuscous above or fuscous throughout, 
slightly tufted at apex below, terminal segment 2 / 3 , sometimes infuscated. 
Thorax pale glossy straw-ochreous, basal half of tegula dark fuscous. 
Abdomen glossy ochreous-whitish. Legs pale golden-ochreous, anterior leg 
suffused with dark fuscous, posterior tibia with fine dense hairs above 
and beneath along basal half of distance between pairs of spurs, tarsus 
bristly below. Fore wing very pale straw-colour with strong golden gloss, 
markings bronze-tawny with a faint purplish tinge. A bronze-fuscous 
attenuated and suffused streak along basal fifth of costa, sometimes broader, 
elongate-semiovate, and more greyish-fuscous tinged; an elongate, suffused 
spot on dorsum at 2 / 5 of wing, in dark specimens connected with preceding 
beyond base of wing by a bronze-tawny irroration; two ill -defined lon- 
gitudinal irrorated streaks in disc above and below middle converging at 
] / 4 of wing, lower one continued along termen to apex, narrowed along 
posterior fifth of termen, thence as a short narrow projection along costa; 
this streak is dilated along lower 2 / 3 of termen and bears there three parallel, 
outwardly oblique elongate transverse blotches of ground colour resting 
on termen, sometimes indistinct; upper longitudinal streak gradually 
curved downward and merging into preceding beyond cell (sometimes this 
longitudinal streak entirely absent). Cilia sordid straw-colour, along base 
straw-whitish. Hind wing fight fuscous-golden, apex and an ill-defined 
narrow streak along upper part of termen golden-whitish. Cilia pale 
ochreous-tawny.
