A. barbula Dogn. (37 cl) is distinguished by much longer discocellulars of both wings; on the hind- barbula. 
wing the two lower radial veins rise from the same place. Head and thorax brownish yellow, abdomen above 
more white; beneath the body is paleo chreous-yellow; palpi, forehead and hips blackish. Forewings narrow, 
with a rectangular apex; white, with a pale ochreous-yellow tinge, in the inner-marginal area brownish. Beneath 
the forewing shows short hair in the whole lower half of the cell and between the median veins and lower 
radial veins. The costa of the hindwing is provided with hair growing longer distally; the colour is on 
both sides a very pale yellowish white. Expanse of wings: 33 mm. Colombia. 
A. trichosema Dogn. (37 d) is similar, larger, the hairy spot of the forewing beneath is much shorter Irichosema. 
and situate only below the cell near its end, between the median veins and radial veins. The forewings are silvery 
white with a brownish proximal margin, only the hindwings yellowish. Expanse of wings: 44 mm. Colombia. 
A. rotunda Hmps. (37 d) is easily recognizable by very narrow forewings and almost 3 times as rotunda. 
large round hindwings. Head and thorax brownish-grey, neck and antennae ochreous-yellow, so is the abdomen. 
Forewings silvery white, in the inner-marginal half purple blackish, also the cell-spaces above it towards the 
margin, as far as the middle radial. Beneath the $ shows very long hair on the forewing in the cell and behind 
it. Hindwings white, tinted ochreous-yellow. Expanse of wings: 46 mm. Colombia, Bolivia. 
A. pseudobisecta Rothsch. (37 d), described according to a 2, is reddish-brown on its head and thorax, pseudobi- 
the base of the collar orange; abdomen light orange, above brownish. Forewings lustrous light yellow, the proxi¬ 
mal margin reddish-brown as far as the submedian fold, and forming a projection to the rise of the lower median 
vein. Hindwings yellowish-white. Expanse of wings: 44 mm. Colombia. 
A. meteura Bmps. (36 k) in the <$ is distinguished by a slight concavity of the distal half of the meteuru. 
proximal margin of the forewing which is beneath covered with erect hair. Hindwings very broad. Head and 
thorax are yellowish-white, tinged brownish, the abdomen of a purer white. Forewings yellowish-white, strewn 
with reddish-brown scales, which are behind the cell condensed to an oblique shade from the costal margin to 
the middle radial vein at the margin. Proximal margin of a deeper brownish colour. Hindwings yellowish-white. 
The $ is less densely dusted brown, and the abdomen likewise tinged brown. Expanse of wings: 38 mm. Colombia. 
A. brunneostriata Hmps. (37 c). Head and thorax reddish ochreous-brown, abdomen yellowish-white, brunneo- 
Forewings ochreous-yellowish white, in the proximal half with dusted red-brown stripes in the cell-spaces, 
also in the cell-end, below the costa and at the apex brownish spots. Hindwings white, tinged somewhat brown, 
towards the margin more intensely so. Beneath the costal half is dusted brown. Expanse of wings: 44 mm. South 
East Peru. 
A. nubens Schs. (37 d) has, like the preceding, no hair on the wings. The shows 4 or 5 bent nubzns. 
spines on the basal part of the antennae, on the abdomen lateral long hair-tufts. Head and thorax smoky grey, 
antennae orange, like the anterior chest, hips and abdomen. Forewings silvery white, at the inner-marginal 
part smoky grey with a yellow costa. Hindwings white, proximally yellowish, at the margin more or less tinged 
grey. The $ has white anterior chest and hips, the abdomen being also white with a very faint yellowish tinge, 
also the costal margin white. Expanse of wings: 38 to 42 mm. Mexico. 
A. involuta Hmps. (= albotestacea Rothsch.) (36 1) greatly resembles nubens-, the however, is involuia. 
without the spines on the antennae, the costal margin of the forewing being turned over and roughly scaled, 
the hindwing beneath showing a large, reddish-yellow scent-scale spot below and behind the cell. Abdomen 
brownish-grey, with brown anal tufts; costa of the forewing in the middle ochreous-yellow, towards the base 
blackish. Expanse of wings: 36 mm. Brazil: Castro (Parana). 
A. revoluta Dogn. (361) has, like the preceding, an inverted and roughly scaled costal margin, revoluta. 
but the androconium is entirely absent. Head and thorax blackishbrown mixed with grey; chest and legs 
ochreous-yellow. Abdomen blackish brown, beneath white. Forewing silvery white, at the proximal margin 
tinged brown, the costal margin orange-yellow; hindwing white, in the costal half yellowish. Expanse of wings: 
30 mm. Colombia. 
A. submacula Schs. (37 f). Head and thorax dark grey, abdomen light grey; shoulder-covers outside submacula. 
and at the apex white. Forewing silvery white, the inner-marginal area brownish-grey. Hindwing white, at 
the anal angle dusted grey. Forewing beneath white, with a grey inner-marginal area and a large, greyish- 
brown postmedian spot, also the margin being greyish-brown. Expanse of wings: 37 mm. Costa Rica. 
A. marginata Drc. Beginning from this species, the are without any secondary sexual marks except marginata. 
the anal tufts. Body purple-blackish, palpi yellowish, forehead and antennae whitish; anal tufts black. Fore¬ 
wings white, at the costal margin t inted yellow, the inner-marginal area purple-blackish; beneath with an ochreous- 
yellow spot in the middle of the costal margin. Hindwings white. In the $ the under surface of the forewing 
and the costal part of the hindwing are brownish-grey. Expanse of wings: 26 to 34 mm. Mexico, Guatemala, 
Costa Rica. 
A. barbipalpia Schs. (37 e) is distinguished by the palpi being covered with long hair turned downward, barbipal- 
Head and thorax brownish-grey and white. Abdomen above dirty white, beneath ochreous-yellow, anal tufts 
brownish-grey. Forewings silvery white, tinted ochreous-yellow; costa ochreous-yellow, towards the base 
blackish; inner-marginal area purple-grey. Hindwings dirty white. Under surface of forewing ochreous-yellow,
