MICROLEPIDOPTERA OF NEW GUINEA 
with dark fuscous bands. Fore wing elongate-triangular, costa curved 
towards extremities, straight in middle, apex subobtuse; termen slightly 
concave above, moderately oblique. Glossy light golden-yellow, markings 
dark fuscous turning blackish towards costal edge. Base of costal edge 
blackish below; a small semicircular spot beyond base of costa, below 
reaching cell, centred with ground colour, connected with base of wing 
by a short marginal streak, sometimes with a triangular connection with 
dorsum beyond base; this spot followed by another similar spot, also 
reaching cell, erect-semiova te, slightly inwards-oblique; an elongate- 
semiovate mark on costa before middle, preceded and followed by a small 
marginal dot, and centred with ground colour and with two transverse 
bars; lower edge of this mark with a slight triangular projection posteriorly 
to base of vein 10; before this projection originates an inwardly curved, 
gradually dilated transverse streak running to below middle of fold, with 
two branches; a broad anterior branch from middle of streak, strongly 
curved downward, abruptly dilated below 1 / 4 of fold, reaching halfway 
between fold and dorsum, centred below fold with a dot of ground colour, 
lower extremity truncate; upper edge of this branch with two triangular 
projections, anterior projection sometimes anastomosing with second 
costal mark; posterior branch of transverse streak running along fold to 
its 3 / 4 , with two dots of ground colour in fold, and is triangularly dilated 
posteriorly; upper posterior angle of this branch anastomosing with an 
outwardly oblique X-shaped mark along and beyond end of cell: four 
transverse erect-triangular streaks along posterior fourth of costa gradually 
becoming shorter towards apex, or two anterior streaks much longer, 
anastomosing below so as to form a U-shaped mark with a narrow 
appendix below, pointing towards tornus; an invert-V-shaped mark in 
tornus with a narrow vertical appendix above, lower posterior extremity 
bifid; a slightly inwards-oblique elongate preterminal patch from termi- 
nation of vein 3 to above vein 6, sometimes triangularly dilated in middle 
anteriorly, followed along terminal edge by three black dots becoming 
larger towards apex, upper 1 dot almost connected with a black dot below 
apex. Cilia pale whitish-yellow, basal third with black dots corresponding 
with terminal markings. Hind wing white, faintly touched with pale 
fuscous, posterior half with transverse rows of pale blackish dots parallel 
to termen. Cilia whitish, touched with yellowish. 
Tegumen erect. Gnathos moderate, hook long, curved, simple. Socius 
narrow, slender. Gnathos with median projections rather long, slightly 
below middle, top robust, densely covered with fine dentations. Transtilla 
invert- W-shaped, slender. Valva slightly dilated towards middle, obliquely 
truncate; costa straight posteriorly; sacculus weak, terminal knob elongate, 
transversely oblique, with bifid bristles. Aedoeagus curved, rather thick, 
with a moderate apical horn. Cornutus, one strong spine. (Slide No. 729 D, 
holotype).
