Forewings suboblong, slightly dilated, termen slightly oblique; 8 to apex; whitish or pale greyish ochreous, more or less sprinkled blackish; an ill-defined costal band of dark fuscous suffusion, occupying about 1/3 of wing; discal stigmata dark fuscous or blackish, first small, sometimes obscured, second forming a narrow-transverse spot; a suffused fuscous terminal line, more or less indistinctly dotted dark fuscous: cilia whitish, suffused fuscous on outer half, more strongly round apex, an antemedian series of indistinct dark fuscous marks or dots.

Cryptophasa aggesta MEYRICK, 1925, Exot. Microl., vol. 3, p. 147. Trans. Ent. Soc. Lond., vol. 87, p. 516, 1938.
Distribution: Netherlands New Guinea: Utakwa River, 3000 feet. British New Guinea: Dampier Island, 3000 feet; Papua, Mafulu, 4000 feet; Kokoda, 1200 feet.
♀ 55 mm (neallotype). Palpus darker greyish-fuscous. Abdomen with a broad orange-coppery band of fine bristles on the dorsum of the second segment. Fore wing broader, dilated, costa considerably curved towards the extremities, especially anteriorly, less curved in the middle, apex obtusely angular, termen little rounded above, more so beneath. Fuscouswhitish, costal half gradually suffused with fuscous, this suffusion broader and darker than in the male, transverse outwardly convex mark on the closing vein broader and more conspicuous: fuscous-blackish; the entire wing more distinctly speckled with fuscous-blackish. Hind wing darker, evenly fuscous, with faint bronze gloss, cilia somewhat paler, with a fine pale basal line. Otherwise as the male and, in my opinion, undoubtedly conspecific.
Rattan Camp, 1200 m, February 17 and 23, 1939. Two males. Araucaria Camp, 800 m, February 21, 1939: neallotype, female. Three specimens.

Remarks: On appearance alone there is good reason to suspect that Cryptophasa aggesta and C. eumorpha are not synonymous as suggested by Bradley and adopted by Common and subsequent authors. This species may not actually be present in Australia.
