than the preceding, often open above; dark speckling denser along the 
dorsum and on the posterior fourth, but not reaching the terminal edge, 
which bears a series of small transverse streaks on the terminations of 
the veins. Cilia fuscous-whitish, suffused with light grew, a basal series of 
transverse dark fuscous streaks corresponding with those along the 
termen. Hind wing dull greyish -fuscous, cilia fuscous-grey with a pale base. 
Ostium moderate, limen a broad weak plate, deeply emarginate and 
almost parted in the middle, median rim somewhat thickened; dorsal wall 
of the ostium, a large ascending bristled plate with subtrapezoid upper 
edge. Colliculum, a small sclerotized tube. (Slide no. 908 D, neallotype.) 
Neallotype 54 mm, Baliem Camp, 1600 m, December 10, 1938. 
Tegumen moderate. Socii thickened. Valva rather narrow, apex blunt, 
a little curved; sacculus under x / 2 , ending in a short truncate process; harpe 
gradually narrowed, serrulate above, pointed. Vinculum moderately long, 
rather broad. Anellus very long, tubular. Aedoeagus long, with a bulbate 
base. (Slide no. 870 D.) 
Baliem Camp, 1600 — 2000 m, November 10 — December 16, 1938. Mist 
Camp, 1800 m, January 26, 1939. 20 males, 35 females. $ 37 — 47 mm, 
5 50 — 57 mm. A rather varying species, as to the dagree of the dark irrora- 
tion of the fore wing in the two sexes that obscures the discal markings. 
Sometimes the circular discal spots are confluent and form one reniform 
transverse mark, centred with whitish, and dark-edged. 
Cryptophasa obscura spec. nov. (fig. 671) 
£ 43 mm. Head creamy-white. (Palpi broken.) Thorax dark fuscous, 
mixed with creamy- white, apical third except the edge and the shoulder, 
creamy-white, patagium enlarged, grey. Abdomen dark fuscous, long- 
haired, narrow transverse bands of fine orange bristles showing through 
scales along the posterior edges of the tergites. Legs, anterior blackish- 
fuscous, median creamy, banded with blackish-fuscous above, posterior 
leg creamy, tibia infuscated above, tarsal segments with black basal rings. 
Fore wing elongate-subtruncate, little dilated, costa slightly curved at the 
base, gently convex in the middle, straight posteriorly, apex obtuse, 
termen straight, vertical above, roimded beneath. Pale fuscous, very 
densely suffused with dark fuscous. A small creamy oblique patch on the 
base of the costa, reaching 1 / 3 across the wing; posterior 3 / 4 of the costa 
with a very narrow creamy streak, interrupted by five elongate marks 
of dark fuscous suffusion on the terminations of the veins 12 — 8, becoming 
smaller posteriorly; an ill-defined streak of the ground colour along the 
upper edge of the cell from the base to before the middle of the wing; 
apical and terminal fifth of the wing less irrorated, only with suffused 
longitudinal dark fuscous streaks along veins not reaching termen; a row 
of small ovate marginal dots on veins from the apex to the tornus. Cilia
