A. strigipennis H.-Schdff. (= circumdata T Vkr., sinica Moore, discistriga Moore, terminata Moore, 
scripta Heyl., fruhstorferi Auriv.) is a very variable animal, with yellow forewings more or less tinted red, the 
marking verj^ much like in the preceding, but the median line not at all bent below the median. The number 
and distinctness of the basal and marginal dots varies a great deal, as well as the extent ot the red tint, but 
the different forms are so much alike that it is useless to denominate them singly. 15 to 35 mm. -—- Very widely 
distributed: China, Formosa, Sikkim, Assam, Sumatra, Borneo, and Java. 
A. unifascia Rothsch. In the $ the antennae, head and thorax are orange-buff. Abdomen greyish 
buff with a very large anal tuft. Forewings orange-buff; a median transverse band is aniline greyish-brown; 
in the basal half and along the veins in the marginal area a number of small aniline greyish-brown dots. Hind¬ 
wing buff with a grey nebulous band in the middle. Length of forewings: 11 mm. Candy, Ceylon. 
A. arcuafa Moore (17 li), likewise allied to the preceding and just as variable. Ground-colour pink 
or more yellowish-red; the dots in the basal and marginal areas are all very fine, the median line is almost 
straight, but obliquer than in unifascia. —- In f. rosea limps, there appears a dark median line on the 
hindwing. — f. aurora Hmps. (17 h) is a form with almost vanished marking. — India, Ceylon, Java. 
A. nubilalis Hmps. (17 i). On the yellow forewing a broad basal area and a very broad postdiscal 
band are united at the proximal margin to a large blackish-brown spot. Hindwing with a dark marginal band. 
— Ganjam, Java. 
A. humilis Whr. (17 h) is orange-yellow with an anterior transverse line formed of oblong spots 
and a broad, blackish-brown postdiscal band showing the usual dental projections on the upper and lower 
radial veins. — semicirculata Heyl. shows in the middle of the wing a connection of the two transverse bands 
by a blackish-brown longitudinal band. — From Sikkim and Burma as far as Java. — The larva is short and 
stout, blackish-brown, very densely haired like a fur, on the dorsum of the 7th and 8th rings white; it lives 
on lichens and is very nimble. It pupates in a dense, blackish-brown cocoon. The imago is yielded after 
12 days. 
A. biseriata Hmps. (17 h) is ochreous-yellow, the transverse lines have disappeared altogether, being 
replaced by transverse rows of black longitudinal streaks; at the cell-end a black dot. -— Borneo. 
A. acteola Swinh. has scarlet forewings tinted ochreous-yellow, with a straight, dull black median 
band; instead of the anterior transverse row a row of short longitudinal streaks, behind the cell another row 
of longer and more distinct streaks, parallel to the margin. Hindwings unmarked pale ochreous-yellow. Thorax 
red, abdomen yellow. — .Siam. 
B. orsova Swinh. is very much like acteola ; the ground-colour is more orange, tinted red in the cell- 
spaces, with an antemeclian a nd a post median transverse band of longit udinal streaks, both not extending 
to the costa; the median band is absent. Hindwings ochreous-yellowish grey. —• Siam. 
A. strigulata Rothsch. with light brown antennae, head and thorax pale orange buff; abdomen 
buff. Forewings light orange-yellow; near the base a transverse band and a much broader postmedian band, both 
formed by confluent, purple brown, small longitudinal streaks. Hindwings buff. Length of forewings: lO 1 ^ mm. 
— Khasia Hills in Assam, April. 
A. lacteoflava Rothsch. head, antennae and thorax dark buff; abdomen buff. Forewings dark 
buff; 6 small, black dots in the basal fourth, a black dot behind the cell and a postdiscal row of small black 
stripe-dots, that on vein 4 being the nearest to the border. Hindwings leather cream-coloured. $ with small 
dots of a lighter black, and the small spots much fainter. Length of forewings: 12, $ 14 mm. Dalhousie in 
North West India, in June. This species having been described in 1913 might be inserted in our Volume 
on the palearctic Lithosiids closed in 1912, on p. 58. — The specifically Indian form was described as aureata 
Rothsch. It comes from the Khasia Hills in Assam, where it was captured in July. The $ differs from the typical 
lacteoflava by the gold-orange buff colour on the head, thorax and forewings, and the small dots on the vertex 
and thorax. On the forewings all the black spots are extended to long, hair-like, black, small stripes, and at 
the margin there is a line of small black dots. All the wings are narrower. 
A. disticha Meyr. (17 i) is much larger than biseriata and of an orange-red ground-colour; the streak- 
spots are reduced to small dots. — Burma.
