MICROLEPIDOPTERA OE NEW GUINEA 
outwardly oblique, just below and parallel to about the fourth fifth of 
the fold; two large rounded tufts on the angles of the cell, interconnected 
by a dark fuscous irroration which is extended as a narrow longitudinal 
streak, not reaching the termen below the apex; an ill-defined, narrow 
oblique whitish longitudinal streak from the upper angle of the cell, 
ending with a white bar just below the apex, extending over the cilia; 
above this streak costa tinged fuscous. Cilia pale ochreous densely mixed 
with tawny, along the lower half of the termen and in the tornus pale 
ochreous, mixed towards the base with dark brown, apical fourth of the 
cilia around the apex whitish with a brown apical line. Hind wing whitish- 
leaden-grey, posterior half irrorated with dark bronze -fuscous. Cilia pale 
ockreous-bronze, along upper half of the termen somewhat infuscated, 
base along the dorsum narrowly mixed with pale metallic-blue scales. 
Tegumen with a strong base, concave. Uncus bipartite; two long 
pending horns (in the mount drawn together, actually separate). Socii, 
a few weak bristles. Valva strong, broad, costa short, rounded, with a 
long, clavate, bristled process rising from its base ; sacculus large, strongly 
and triangularly dilated, bristled posteriorly, top rounded, separate, 
cucullus absent. Anellus indefinite. Vinculum very small. Aodoeagus long, 
submembraneous, rather slender. Cornuti remarkable: a broad and long 
tortuous denticulate band, with a spike below its top, the top narrowed 
and produced, with larger denticulations, proximal extremity of this 
band forming a long narrow sclerotized filament. (Slide no. 1075 D, type.)

Head with smoothly appressed scales, face somewhat retreating. 
Ocellus posterior. Proboscis moderate, scaled above. Antenna 3 / 4 , in the 
male minutely ciliate, scape moderate, slightly flattened, subconcave, 
without a pecten. Labial palpus moderately long, recurved, ascending, 
with smoothly appressed scales, slender, median segment moderately 
dilated, terminal segment under 1, scaled, acute. Maxillary palpus very 
small, subappressed. Thorax without a crest. Abdomen rather smoothly 
clothed with dense minute scales. Posterior tibia clothed with rough hairs 
above. Fore wing elongate-ovate, without raised scale-tufts; lb furcate 
at the base, furca over 1 / 4 , 2 from 4 / 5 , 3 from well before the angle, 4 from 
the angle, 5 almost connate with 4, 7 and 8 stalked, 7 to the costa, 11 
from the middle. Hind wing 1, elongate-subtrapezoid, cilia under 1; cell 
extremely short, about 1 / 5 of the wing length, lower edge with an elongate 
hyaline thickening; 2 abruptly curved towards the base, short-stalked 
with 3, stalk from before the angle, 4 and 5 closely approximated at base 
to each other and to the stalk of 2 and 3, 4 from the angle, 6 and 7 parallel.
