MICROLEPIDOPTERA OF NEW GUINEA 
97 
suffused edges, at about 2 / 5 of costa, reaching beyond middle of upper 
edge of cell, connected by an oblique row of faint grey and blackish 
minute irregular strigulae with 2 / 3 of dorsum; costal patch formed by 
two rather irregular rounded dots: upper dot on costa beyond middle, 
dark grey edged with black, lower dot below and slightly beyond pre- 
ceding, dark brown, marked with black above, and a third small black 
dot at 3 / 4 of costa; a smaller blackish dot on costa before apex; terminal 
fourth slightly suffused with grey, with moderate round black inter- 
neural dots, arranged in undulating rows; costa and especially dorsum 
denser irrorated with dark grey and blackish, dorsum also transversely 
strigulated with dark grey. Cilia white, with an interrupted suffused dark 
grey antemedian band. Hind wing rather dark fuscous-grey, darker 
towards apex, becoming whitish towards base. Cilia fuscous-greyish, 
whitish towards tornus. 
Limen straight, dilated, little sclerotized, with a split in middle, rectangu- 
larly projecting below, angles broadly rounded. Colliculum long, slightly 
narrowed below. Cestum very strong, short, coiled, with a broad median 
furrow, end strongly projecting, denticulate, deeply asymmetrically excavate 
at the sides, terminal fold broad, subtrapezoid, shortly edged. Signum 
robust, little curved, short-serrate. Corethrogyne scales somewhat varying 
in size, clavate, top lanceolate, with a long projection (Slide No. 383 D). 
Araucaria Camp, 800 m, March 18, 1939. One specimen. Closely allied 
to I. melanoclera Meyrick. 1938, distinct by more extended markings and 
by genitalia.
