A. perpensa Schs. ( = laticilia Drc. part, nec WTcr.) (36 k) is white on its body and wings, abdomen 
beneath with orange hair-tufts; palpi and legs blackish-brown, the costa of the forewing is covered with short 
red-yellow hair, the inner-marginal half dusted blackish-brown, the same on the under surface the marginal 
area of the forewing and the costal-marginal part of the hindwing. The under surface of the forewing shows in 
the cell a large, orange scent-scale spot and below it tufts of long, orange, rough scales; a similar spot on the 
hindwing above in and behind the cell. Expanse of wings: 36 mm. From Mexico (Jalapa, Misantla, Vera Cruz). 
A. fumidicosta Hmps. (= laticilia Drc. part, nec Wkr.) (36 k). Similarly coloured as perpensa, but 
the under surface brown, only the anal tuft orange. The costal margin of the forewing in the is bulged out 
near the base, in the middle turned over downward, and thereby appearing concave, towards the base with 
short blackish hair. Underneath the forewing exhibits a stripe of long, erect, orange-yellow hair below the 
cell and the hindwing similar hair above along the subcostal. The $ has narrower wings and a narrower brownish- 
grey proximal margin. Expanse of wings: 32 to 36 mm. Guatemala. 
A. argentea Wkr. (37 c). White, head and thorax blackish-brownish, abdomen tinted ochreous-yellow; 
long hair-tufts on the anterior femora and on the ventral side orange. Forewing white, in the inner-marginal 
half blackish-brown, in the $ the costa with orange hair. Beneath the forewing is covered at the end of the 
median with long, dark brown, towards the base more orange-yellow hair, the marginal area blackish-brownish. 
Hindwing white, in the disc ochreous-yellow, the cell covered with orange-yellow, woolly hair. In the $ the 
dark inner-marginal area is narrower. — vestalis Schs. has the marginal area of the forewing beneath all 
white, and mostly an orange-yellow hair-spot in the disc of it. Expanse of wings: 36 to 46 mm. Brazil. 
A. oediphlebia Hmps. (37 c) is marked by a round, knob-like, brown swelling on the median of 
the forewing beneath near the cell-end and ochreous-yellow scent-scales in the inner-marginal half, on the 
hindwing above in the costal half. The body is moreover white, with a brown hue; the wings silvery white, 
at the proximal margin broadly brown. Expanse of wings: 30 mm. Ecuador. 
A. megasema Hmps. (37 c) is very similar, larger. The swelling on the median is elliptic, much 
larger, extending from the discal fold to the lower median vein. Body and wings are likewise similar, but the 
hindwing above, in the costal half, light orange brownish. Expanse of wings: 34 mm. Peru. 
A. exscissa Schs. (37 c). Head and thorax smoky grey, forehead and abdomen more yellow-reddish 
grey. Forewings distally narrow; in the basal two thirds the proximal margin is strongly lobed as far as the 
retracted inosculation of the lower median vein; the distal third runs straight to the proximal angle, into 
which the upper median vein terminates; the colour is a silvery white, the inner-marginal lobe brownish-grey, 
the costa ochreous-yellow. The hindwings are broad, with a rounded margin, silvery white; a large, yellow 
scent-scale spot in the cell-base is covered by the inner-marginal lobe; below and behind the cell the wing is 
yellow-brownish, with a brownish-grey postmedian shade above the lower median vein. Beneath the discal 
part of the forewing is covered with rough, yellow scales, below the cell a cinnamonbrown scent-scale 
stripe extends; distal margin brownish-grey. Under surface of hindwings blackish-brown; proximal margin 
and border whitish. Costa Rica. 
A. barbicosia Hmps. (36 k) has no scent-scale spots, only the costal margin of the forewing is blackish- 
haired in the <$. White; head and thorax smoky grey; the larger, basal part of the forewing is tinted yellow- 
brownish, in the terminal third of the proximal margin there is a blackisli-brown spot. Hindwings white, 
in the basal half yellowish. Expanse of wings: 32 mm. Brazil (Rio de Janeiro). 
A, albivenis Schs. (36 k). Head and thorax are dark greyish-brown, the forehead yellow-reddish; 
palpi dark brown, white haired. Abdomen above grey, hairtufts beneath and laterally reddish-white. Legs white, 
partly striped grey; anterior tibiae black with white rings. Eorewings light grey, the veins and discocellular 
silvery white, the inner-marginal area smoky grey; at the cell-end and between and above the median 
veins the grey colour is darker; in the $ the costal margin exhibits brownish hair. Hindwings white, at the 
costal margin and border tinged smoky grey. Beneath the forewings are smoky grey, distally lighter, hind¬ 
wings white, at the costal margin yellow-reddish. In the 9 the forehead is white, also the forewings entirely 
white, only between the median veins near the cell tinted grey; the proximal margin dark brownish-grey. Expanse 
of wings: 26 to 28 mm. Costa Rica. 
A. polysemata Schs. (37 d) has much broader wings than the preceding. White, the body with 
a smoky giey tinge; proximal margin of the forewing dusted smoky grey. Costa towards the base blackish. 
The $ shows beneath a hairy costal fold, below the cell a light reddish-yellow hair-stripe, being still much 
longer haired on the lower median vein. Hindwings towards the margins somewhat brownish, beneath with 
white, woolly hair in the cell and with brown hair above it, and a black scent-scale spot below it. The $ 
has more purely white wings. Brazil. 
A. auranficaria Schs. (36 k). Body above grey, beneath yellow-reddish white. Forewings white, at 
the proximal margin faintly grey. Hindwings white, with a large scent-scale spot in the basal half of the cell, 
and a grey shade on the lower median vein at the margin. Beneath the forewing exhibits below the 
cell a stripe of hair which grow much longer between and above the median veins, like in the preceding species. 
Expanse of wings: 26 mm. French Guiana. 
A. fasciculata Wkr. ( = hypotricha Fldr.) (36 1) is purely white; palpal terminal joint black; legs brown¬ 
ish. The exhibits beneath on the median of the forewing rough, ochreous-yellow hair, on the upper surface 
of the hindwing in the cell and somewhat behind it woolly, yellow hairing. Expanse of wings:. 30 mm. Venezuela.
