MICROLEPIDOPTERA OF NEW GUINEA 
angle of cell, middle dot sometimes smaller, elongate and somewhat 
approximated to third; grey suffusion forming an elongate patch along 
dorsum from x / 4 , hardly reaching above fold; a transverse spot beyond 
cell, connected with costa before apex, strongly narrowed below; a 
moderate fascia along termen from below apex to above tornus, connected 
below with preceding, sometimes extended and confluent with preceding, 
forming together a grey patch on terminal l / 5 of wing, terminated above 
by vein 9, with a whitish suffusion before apex and a curved grey suffused 
projection along termen to lower edge of cell. Cilia white, basal half suffused 
and faintly barred with pale grey, except opposite apex. Hind wing with 
vein 6 weak but distinct throughout, veins 3 and 4 stalked; whitish, 
faintly suffused with grey along termen and in apex; cilia white. 
Tegumen broad, short. Uncus short, narrow. Gnathos, a small, short- 
bristled and curved projection at each side. Va-lva moderate, base concave, 
cucullus ending in an obliquely truncate point; sacculus with a long 
straight projection, terminating in a short, curved tooth. Aedoeagus 
slender, basal half clavate, apical rather small, asymmetrical, top truncate. 
Cornuti absent. Vinculum broad, triangular. (Slide No. 849 D, holotype). 
Ostium rather broad. Limen, a large erect-ovate plate, with concave 
upper edge, a long acute projection at each side. Ductus bursae finely 
granulate. Bursa copulatrix long, narrow, simple. (Slide No. 845 D, 
allotype). 
Top Camp, 2100 m, January 22, 1939 (holotype, male), January 25 — 26, 
1939. Baliem Camp, 1700 m, November 16 — 27, 1938 (allotype, female). 
Three males, one female. Closely allied to M. heptaspila Meyrick, differing 
by sparser black markings, and by less distinct postcellular transverse band. 
Meridarchis oculosa spec. nov. (fig. 542) 
(J 20 mm. Head, antenna, palpus white, basal and anterior half of 
median segment of palpus suffused with black. Thorax (imperfect) white, 
suffused with black medianly; tegula with a black median basal spot. 
Abdomen and legs white, anterior pair of legs suffused with black. Fore 
wing with veins 3 and 4 separate; elongate-triangular, slightly curved in 
middle, costa gradually curved throughout; apex rather obtuse, termen 
slightly rounded, oblique. Sordid white, markings black and suffused grey. 
Base of costa with a narrow black streak; three black dots in a straight 
very oblique series: first costal, semicircular, confluent with posterior half 
of preceding streak, not reaching middle of wing ; second rounded, somewhat 
smaller, just above fold at 1 / 4 of wing length ; third slightly more distant, 
elongate-subovate, smaller than second ; another, almost straight series of 
four black dots, perceptibly converging with preceding series, from slightly 
beyond 1 / 3 of costa to upper angle of cell ; first dot of this series ill-defined, 
small, elongate, greyish, other dots round, black, tolerably equidistant, 
ultimate largest; a short marginal dark grey streak on middle of costa;
