MICROLEPIDOPTERA OF NEW GUINEA 
Aedoeagus with orifice strongly chitinised, oblique, point short (Slide 
No. 311 D, holotype). 
Limen rather broad, gradually convex, lateral emarginations moderate, 
roimded, lateral projections short, lateral rods rather short, moderately 
dilated, inner edge rounded. Colliculum short, with a wide ventral split. 
Cestum broad, tortuous, terminal fold broad, with thickened edges. 
Signum rather small. Eighth tergite truncate (Slide No. 326 1), allotype). 
Valley two km northeast of the crest of Wilhelmina Top, 3400 m, 
September 19, 1938; 3600 m, September 4, 1938; Hill north of Lake 
Habbema, 3850 m, August 24, 1938 (allotype, female). Hills at the foot of 
Wilhelmina Top, 3850 m, September 8, 1938 (holotype, male). Two males, 
two females. Allied to preceding, distinct by the reddish colouring of the 
thorax, the blackish base of the abdomen and the blackish scales on the 
dorsum of the hind wing. In one female (worn) the fore wing is faintly 
tinged ochreous, the terminal segment of the palpus is mixed with blackish.

¥ 28 29 mm. Head and palpus deep fulvous, terminal segment of palpus 
suffused with brown, antenna with scape dark fulvous, flagellum dark 
brown, dotted fulvous above. Thorax dark fulvous anteriorly, pale fulvous 
posteriorly. Abdomen ochreous-whitish, venter darker ochreous, corethro- 
gyne extremely large, ochreous-fulvous, ovipositor lobes grey. Legs 
ochreous, suffused with dark fulvous. Fore wing with costa gradually 
considerably curved anteriorly, straight posteriorly, apex rounded, termen 
almost straight, vertical above, rounded beneath. Shining ochreous, 
narrowly suffused with pale fulvous along edge, especially towards termen ; 
terminal edge and a suffusion on a short marginal scale tuft towards base 
of dorsum somewhat darker fulvous. Cilia pale golden-yellow, with a 
faintly darker antemedian line. Hind wing glossy ochreous-yellowish, paler 
towards base and dorsum, veins darker. Cilia concolorous, with a faint 
antemedian line. 
Limen moderately broad, broader in middle, rater weak, gradually 
convex, lateral emarginations moderate, somewhat oblique, rounded, 
lateral projections rather long, strong. Colliculum strongly sclerotized, 
rounded, ventral split narrow. Cestum broad, tortuous, and with a coil 
above bursa. Signum strong. Eighth tergite with posterior edge mem- 
braneous, forming a short collar around ovipositor. Anapophyses long 
(Slide No. 325 1). holotype). 
Moss Forest Camp, 2800 m, October 9 — November 5, 1938. Two females. 
Perhaps allied to preceding, but larger, with corethrogyne twice as large. 
One specimen (paratype) with fore wings, head and abdomen whitish- 
yellowish, palpi, thorax and tegulae orange anteriorly, fore wing with a 
narrow orange-yellow margin, hind wing yellow. Cilia in both fore and hind
