MICROLEPID OPTERA OP NEW GUINEA 
pale ochreous, median segment with a short narrow brown longitudinal 
strigula in middle above, beyond middle slightly irrorated with grey, viz., 
laterally and below, fringe white, terminal segment with a small partly 
concealed blackish basal dot above. Antenna dark fuscous, ringed with 
ochreous, scape whitish, suffused with greyish-fuscous above. Thorax 
ochreous-whitish, slightly suffused with pale greyish anteriorly, meso- 
thorax grey, edged with whitish. Abdomen pale ochreous, corethrogyne 
light ochreous. Legs pale ochreous, anterior tibia and tarsus dark fuscous, 
except tops of tarsal segments. Fore wing elongate-truncate, little dilated, 
costa strongly curved at base, almost straight posteriorly, obtuse, termen 
hardly sinuate above, rounded beneath, little oblique. Whitish, more or 
less tinged ochreous, marbled and retinate with light ochreous, markings 
fuscous. Two parallel narrow strongly oblique strigulae: from costa 
beyond base and from 1 / 6 of costa to about middle of disc, respectively, a 
small dot on costa at 1 / 4 ; transverse fascia rather narrow, beginning with 
a subquadrate dot on costa at 1 / 3 , to 3 / 5 of dorsum, ill-defined edged by 
narrow interrupted fuscous lines, both outer and inner edge angulate 
anteriorly at 3 / 5 ; costal patch somewhat beyond 2 / 3 , formed by three 
distinct fuscous quadrate dots arranged in a triangle, lower one slightly 
elongate, somewhat oblique, connected by a faint light fuscous fascia 
with tornus; two smaller fuscous dots on costa before apex; two series of 
blackish points tolerably parallel, curved, oblique, running from second, 
and from third costal dot to termen above tornus, and to termen below 
apex, respectively; dorsum with a row of fuscous dots or somewhat 
suffused with fuscous towards base. Cilia whitish, with a rather broad 
interrupted fuscous median line. Hind wing whitish, posterior half marbled 
with greyish, cilia whitish with a greyish-fuscous antemeclian line. 
Limen dilated, membraneous in middle, lower edge semicircular, angles 
short, truncate, emarginations shallow. Colliculum moderately long, 
narrowed in middle. Cestum rather short, little coiled, end rounded in 
middle, little excavate at the sides, terminal fold small, narrow, elongate. 
Signum slender, curved, long-dentate. Corethrogyne scales broad, clavate, 
top rounded, with a short projection, base slightly dilated (Slide No. 381 D, 
holotype). 
Moss Forest Camp, 2800 m, October 9 — November 5, 1938 (holotype). 
Two specimens. West Central New Guinea, Wissel Lakes, October 1, 1939 
(J. K. van Eechoud). One specimen. Closely allied to marmorala, distinct 
by light ochreous tinge, by fuscous instead of blackish markings, by 
slightly shorter angulation of transverse fascia in fore wing, and by 
genitalia.
