A. sienna Hmps. (42 f). $ deviates from subnotata by the hindwing being uni-coloured dark red-brown 
without an orange band . Beneath not hued orange. -—- $ differs from plana by a reddish hue. Expanse of wings: 
30, $ 36 mm. Nilgiris, Ceylon. 
A. subnotata Wlcr. (42 g). <$ dark red-brown. Forewing with indistinct lines, the cell-spot on an orange 
patch. Hinclwing darker, with an orange discal band from the beginning of vein 2, expanded towards the 
margin. Beneath the basal and dorsal areas of both wings are hued orange. Expanse of wings: 26 mm. Ceylon, 
Nilgiri Hills. — According to letters received from Seitz, the $ is entirely dissimilar to the <$, of a light yellowish- 
grey, the forewing marked with small dark stains; the insect has a stout body, similar to the Neorgyia ochracea 
B.-Bak. (45 a), only smaller and a little more intensely marked. The <$<$ fly on sunny days, but always in the 
shade of bushes and hedges and only some centimetres above the ground. The <$<$ are in some localities very 
common. 
A. fenestriculata Strand (42 k). forewing light brownish-grey, in the basal half somewhat ochreous- 
yellowish. The discocellular punctifornr spot is black, near the apex two round vitreous spots, one in area 7 
being almost punctiform, the other in area 6 four times as large. Fringes scarcely lighter. Under surface except 
the costal margin lighter. Hindwing above and beneath whitish, at the apex above feebly dusted with a brownish 
grey, at the margin beneath 5 brownish-grey spots. Chest white, the other part of the body yellowish. Expanse 
of wings: 22, length of wings: 12 mm. Central Sumatra. -—- kinabaluensis Strand. $ i s larger (expanse of wings: 
25 to 27 mm), the body with more whitish hair, the dark band of the costal margin of the forewing still more 
distinctly marked like the marginal spots of the hindwing beneath. The angle of the margin on the hindwing 
sharper than in fenestriculata. Kina-Balu (North East Borneo). 
A. risoria Swinh. (42 f). Antennae black with white shafts. Palpi and frons ochreous. Head, body 
and forewing light reddish-grey with some indistinct, blackish-brown internerval streaks. Hindwing brownish- 
grey, lighter in the dorsal area. Fringes of both wings dark reddish-brown. Under surface lighter, both wings 
equally coloured, the apex of the forewing with a dark grey area. Expanse of wings: 54 mm. Java. — Allied 
with A. socrus. 
A. socrus Hbn.-G. (47 a). Forewing ferruginous or merging into orange, in the marginal area dark 
brown, which colouring is prolonged in the middle of the wing towards the base, but by far not reaching the 
base; in the middle of the dark area there are two small, blurred spots of the ground-colour to be recognized. 
Hindwing uni-coloured orange, but with dark fringes. Beneath the forewing is dark at the apex, otherwise uni¬ 
coloured yellowish-red, thus lighter than above. Expanse of wings: 35 mm. Java. 
A. mirma Swinh. (42 g). $ orange-yellow; the combs of the antennae black, head and thorax brown. 
Forewing with a large, brown discocellular spot and a dark brown apical band, on the costal margin, distal margin, 
and at the base some lighter brown spots, only in the middle of the wing there remains a spot entirely void 
of the brown dusting. Hindwing with a broad dark brown costal area. Beneath the wings are dusted with 
brown only at the apices, the body and legs of a pale whitish-yellow. The shape of the wings as in flaveofusca 
Swinh. (42 g). Expanse of wings: 24% mm. Sumatra. 
A. atrescens Hmps. (42 g). head and anal brush red-brown, thorax and abdomen brown. Forewing 
brown, partly reddish, with very indistinct, undulate antemedian, postmedian and submarginal lines. Hindwing 
blackish-brown, the fringes of both wings red. Expanse of wings: 20 mm. India (Khasis). 
A. glebula Swinh. (42 g). dark brown. Forewing with an indistinct, whitish, fine, antemedian trans¬ 
verse line and a similar, distally curved discal line. Hindwing uni-coloured. Fringes ochreous with darker 
spots. Expanse of wings: 24% mm. Padang (West Sumatra). 
A. niasana Swinh. rf: palpi and frons ochreous, antennae purple black, body and wings black, a ligh 
longitudinal streak below the cell in each wing, a light moon-spot at the end of the cell of the forewing. The 
wings beneath as above, abdomen beneath ochreous. Expanse of wings: 29% mm. Nias. 
A. cometaris Btlr. (42 h). Forewing light smoky-brown with indistinct black figures. Hindwing dark 
greyish-brown, the costal third except the margin, black, the latter as well as a broad, proximally narrowed 
longitudinal streak white. Body dark dreyish-brown. Forewing beneath whitish brown with a blurred marking. 
Hindwing almost as above; body whitish brown. Expanse of wings: 43 mm. Alu (Salomons), Guadalcanal
