A. unicolora Beth.-Bak. is very much like the following, quite pale ochreous-yellow at the proximal unicvloru. 
margin below the cell somewhat darker; the first three fourths of the costal margin are bordered with grey. 
Hindwings diaphanous, yellowish-white. -— Dinawa and Aroa River (New Guinea). 
A. uniformeola Hmps. (17 k) is unicolorously pale straw-coloured. — From Borneo and Java, Talant, uniformeo- 
Sangir, and the Salomons. — The plush-like and black haired larva lives on mosses growing on wet walls and 
yields the imago after a 10 days’ pupal stage. 
A. frigida W hr. (= diffusa Wkr.) (18 a) has brown forewings with ante- and postmedian rows of frigida. 
white dots and white spots at the costal, proximal and distal margins. •— Widely distributed from Sikkim, Assam 
and Burma to Borneo, Sumatra and Java. 
A. griseotincta Rothsch. $: antennae brown, head, thorax and abdomen whitish creamy-grey, towards griseotineta. 
the anus more whitish. Forewings light yellowish-brown, some large spots at the costa and margin creamy- 
white, a subterminal row of 5 spots dirty creamy-white. Hindwings white with a greyish border. Length of 
forewings: 14 mm. Pontianak in South West Borneo. 
A. citronopuncta Rothsch. Both sexes with dark brown antennae; head dark golden-yellow; thorax citrono- 
aniline-brown, tegulae and two lines dark golden yellow. Forewings aniline-brown, along the costa, proximal P' l(ncta - 
and distal margins rows of large, golden yellow spots and of small, irregular, golden yellow spots dispersed 
across the disc, forming three badly marked rows. Hindwings buff with brown fringes. Length of forewdngs: 
$ 10, $ 12 mm. From the Kumusi River in British New Guinea. 
A. hilaris Wkr. is somewhat like the following. The markings are more blackish; the anterior trans- hilar is. 
verse line is proximally angled on the median and inner-marginal vein, distally angled on the submedian fold 
and touches here a feebly broken median line; the discal spot is round, blackish. Ceylon, Java. 
A. bizonoides Wkr. (= tabida Snell.) (18 a) differs from hilaris by its more brownish markings, bizonoidcs. 
plainly curved anterior transverse line, the absence of the median line, and by a longish median spot. From 
Perak, Sumatra and Borneo. 
A. simplex Pagenst. has yellowish-grey or dark grey forewings without any further marking; chest simplex. 
and abdomen are grey, anal tuft yellowish. The hindwings are whitish, at the distal margin somewhat darker. 
On the under surface the margins of the forewings are somewhat lighter than the ground. New Pomerania 
(Kinigunang). 
33. Genus: Priuastira Hmps. 
Proboscis fully developed, palpi extending somewhat beyond the forehead; $ antennae ciliated, posterior 
tibiae with 2 pair of spurs, abdomen roughly haired. Forewing rather short and broad, covered with hairy 
scales; veins 3 and 5 rise near the cell-angle, 6 below the upper angle; 7, 8, 9 petioled, 10 separate, 11 anastomo¬ 
sing with 12. On the hinclwing 3 and 5 rise from the cell-angle, 4 is absent; 6, 7 petioled, 8 rises from the 
middle of the cell. Type: P. pyrrhopsamma. 
P. pyrrhopsamma Hmps. $ orange-yellow; antennae and legs above blackish; forewings with black vyrrlw- 
hair mixed with orange; a diffuse, dentate, antemedian, median and postmedian line black, obtusely angled psamma 
on the median; antemarginal traces of a line, at the margin black dots. Hindwing with a dark marginal band, 
beginning at the costa and growing narrower towards the anal angle. Sydney. 
34. Genus: Ctywiiiisura Hmps. 
Closely allied to Asura, from which it deviates by the 5th subcostal rising much farther towards the 
margin; the 3rd rises much farther towards the cell. The porrect, short palpi do not extend beyond the some¬ 
what anteriorly convex forehead. The posterior tibiae are without the median spurs. The wings are thinly 
scaled and in the $ with an androconium below the costa behind the middle. 
G. saginaea Trnr. (17 cl) has pale yellow wings with brownish markings, an anterior transverse line saginuca. 
being somewhat proximally angled on the submedian fold and connected with the base by two longitudinal 
stripes at the costa and below the cell, whilst in the middle it is connected with the proximally flawed median 
line; a discal clot, behind it a very oblique line joining the median line at the proximal margin; before the margin 
a subterminal line strongly dentate on the 1st and 3rd radials. Hindwings yellowish-white. Queensland (Cairns).
