MICROLEPIDOPTERA OF NEW GUINEA 
69 
Proterocosma dualis spec. nov. (figs. 610, 611) 
$ 9 mm, $ 11 mm. Head, antenna, thorax white, tegula brownish- 
fuscous. Palpus with the median segment dark grey, terminal segment 
white. Abdomen fuscous-grey, in the male the sides and the venter silvery- 
grey. Legs fuscous-white with silvery gloss, anterior tibia and tarsus 
blackish above. Fore wing brownish-fuscous, a creamy-white dorsal 
streak, on the posterior third of the wing becoming silvery-white, reaching 
from the base to the apex, attenuated towards the extremities, slightly 
dilated towards 3 / 4 of the wing, edge well-defined, serrate, ( ilia along the 
costa and around the apex dark fuscous-grey, sordid white elsewhere. 
Hind wing leaden-whitish, cilia fuscous-creamy. 
Anal tube sclerotized. (Tegumen damaged.) Valva cardinate, narrow, 
its twisted posterior part elongate, truncate, bristly. An elongate sub- 
membraneous lobe parallel to the valva represents a paired organ which 
we are not able to identify; perhaps these bags are formed by the mem- 
branes of the seventh segment and bearing the coremata. Bases of valvae 
are tightly connected with each other, so as to form a circular plate, being 
the sclerotized diaphragma, with a small central opening for the aedoeagus. 
The latter is moderate, curved, in our figure (dotted) connected with an 
intricately folded large anellus. (Slide no. 1068 1), holotype.) 
Apophyses slightly undulate. Limen, a denticulate concave transverse 
plate, with a central short rising dilated tube representing the ostium. 
Ductus bursae and bursa copulatrix simple. (Slide no. 1069 D, allotype.) 
Rattan Camp, 1200 m, March 4, 1939 (holotype, male). Iebele Camp, 
2250 m, November 28, 1928 (allotype, female). Two specimens. Female in 
damaged condition, but apparently conspecific. 
Acleracra gen. nov. (fig. 613) 
(iy.hjQOQ = poor, (iy.no; = marge 
Head smooth. Ocellus posterior. Proboscis developed. Antenna °/ 6 , 
filiform, subserrulate, minutely ciliate in the male, scape elongate, slightly 
clavate and flattened, without a pecten. Labial palpus very long, slender, 
smooth, recurved, terminal segment 1, acute. Maxillary palpus absent. 
Posterior tibia smoothly scaled, a few projecting hairs in the middle 
above. Fore wing lanceolate, 2 from 3 / 4 , 3 from halfway towards the 
angle, 4 from angle, 2 — 4 long, running close together at the base, diverging 
posteriorly, 4 longest, converging with 6 posteriorly, 5 absent, 7 and 8 
out of 6, 9 separate, from angle, 10 from rather before angle, 11 absent. 
Hind wing */ 2 , narrowly lanceolate, with a costal shoulder, cilia 4, 2 5 
remote and parallel, cell open between 5 and 6, 6 and 7 closely approxi- 
mated towards the base. 
Genotype Acleracra pancarphalea spec, nov., male. 
Allied to Strophalingias Meyrick, differs by the absence of vein 5 in 
the fore wing and by the presence of all veins in hind wing.
