MICROLEPIDOPTERA OF NEW GUINEA 
sinuate, running posteriorly along vein 9 to costal patch, in male less 
distinct ; a dark brown dot on costa before and beyond preceding streak, 
continued below by a short transverse ochreous strigula ; a moderate trans- 
verse patch: on closing vein and beyond cell, respectively, both these 
patches obliterate in male ; posterior third of costa with four large, some- 
what elongate brown dots becoming smaller and paler posteriorly; first 
dot with an oblique moderate rather irregular brownish-ochreous streak 
almost to vein 6, narrowed and curved below; first dot connected by faint 
ochreous suffusion with following costal dot, together these dots indicate 
costal patch; in male only costal dots perceptible, smaller and fainter; a 
moderate subtriangular spot above dorsum before tornus, truncate and 
mixed with brown posteriorly, in male represented by a single brown 
point on vein 2; a conspicuous preterminal triangular mark, with base 
almost parallel to terrnen, running from termination of vein 2 to above 
vein 7, with top acutely projecting between veins 4 — 5, reaching more 
than halfway towards cell; this mark deep brownish-ochreous, with upper 
and lower parts and projecting top deep brown, its lower angle narrow; 
triangular mark in male entirely deep brown, narrower ; edge of costa and 
dorsum between markings dotted with brown, termen with a row of dark 
brown dots on ends of veins. Cilia whitish, mixed with light ochreous, an 
interrupted narrow deeper ochreous antemedian fascia. Hind wing with 
veins 6 and 7 stalked : whitish with pale yellowish gloss, a marginal series 
of blackish round dots on veins 2 — 8, and faint greyish marbling along 
costa; cilia glossy whitish. 
Tegumen robust. Uncus rather strong, hooked, apex slightly dilated, 
short-bifid, tops rounded. Socius, a moderate flap, bristled along edge. 
Gnathos strong, arms sinuate, top thickened, with two rising flattened 
truncate horns. Transtilla absent. Valva with costa concave, excavate 
posteriorly; cucullus thickened, curved, sacculus deeply excavate, with a 
short projection posteriorly, strongly bristled along outer side; harpe 
represented by an ovate, corrugated patch, edged with bristles. Aedoeagus 
pistol-shaped, two small dentations above orifice. Cornutus, a single spine. 
(Slide No. 701 1), allotype). 
Genital segment broad below, abruptly narrowed, tubular above, 
membraneous. Anapophyses dilated basally. Limen forming an ovate 
weak plate at each side, with dotted surface and a small crescentic rod in 
middle. Ductus bursae narrow, rather short, curved. Bursa copulatrix 
moderate, spheroid. Ovipositor weak, lobes rather broad, tortricoid. 
(Slide No. 694 D, holotype). 
Lake Habbema, 3250 — 3300 m, August 21, 1938 (holotype, female), 
end July — end August, 1938. Moss Forest Camp, 2600 m, October 9 — 
November 5, 1938 (allotype, male). Two males, eight females. Rather 
variable. We designate the female as holotype, as both male specimens 
are worn. A conspicuous, distinct species.
