A. steniptera Hmps. (37 i). Forewings very narrow, silvery white with a blackish-brown inner-marginal 
band, above it tinted ochreous-yellow. Costa ochreous, towards the base blackened. Hindwings yellowish- 
white, towards the margin darkened. Forewing beneath yellowish, at the margin darkened, with a tooth projec¬ 
ting into the cell. Anterior body blackish-brown, vertex, collar, shoulder-covers and abdomen ochreous-yellow. 
Expanse of wings: 30 mm. Colombia. 
A. flavicornis Rothsch. (37 i). Head blackish-brown, vertex and antennae orange; collar white, at 
the apex brownish; thorax above blackish-brown, shoulder-covers orange, at the ends white; abdomen orange- 
yellow. Forewings silvery white, at the proximal margin with a narrow, blackish-brown, grey-lustrous stripe; 
costal margin yellow, towards the base brownish. Hindwings white, at the apex tinted brown. Expanse of 
wings: 32 mm. Peru. 
A. sordida Rothsch. (37 i) is light reddish-brown on its head and thorax, on the abdomen yellowish- 
white. Forewings yellowish-white, at the proximal margin brownish with a faded, blackish-brown oblique 
shade along the lower median vein. Hindwings white. The $ is scantily strewn with red-brown scales and 
without the oblique shade. Expanse of wings: $ 36 mm, $ 38 mm. Colombia. 
A. tolteca Schs. (36 1). Body brownish-grey; palpal base, antennae, legs and anal tuft ochreous-yellow. 
Forewings silvery-white with a brownish-grey, darkened inner-marginal area and a yellowish costal margin. 
Hindwings dull ochreous-yellow. Under surface of forewings blackish-grey with a large, yellowish postmedian 
spot. Expanse of wings: 34 mm. Mexico, Brazil. 
A. corcovada Schs. (= postimparilis Rothsch.) is much smaller than the preceding, otherwise somewhat 
similar, but the abdomen is whitish and the proximal margin of the forewing blackish-brownish, in the basal 
half quite black. On the under surface yellow dusting extends close to the apex. Expanse of wings: 26 mm. 
From Brazil and Bolivia. 
A. umbrosa Dogn. Head and thorax blackish-brown; palpi, legs and abdomen ochreous-yellow, the 
latter above darkened; forewings ochreous-yellow with a blackish-brown inner-marginal half. Hindwings 
lighter. Expanse of wings: 32 mm. Ecuador (Loja). 
A. ochrota Dogn. (36 1) is a very small species, on the body and wings light ochreous-yellow, the 
proximal margin of the forewing of a somewhat deeper yellow. Hindwings somewhat lighter, with a faint grey 
tinge. Forewings beneath tinted more grey. Expanse of wings: 22 mm. Colombia (2000 m). 
A. venosa Schs. (37 i). Easily recognizable by the grey forewings striped white on the veins; the 
costal margin is blackish. Hindwings white, with a darkened costal area. The body is grey with a white spot 
on the metathorax; palpi, forehead, base of antennae, and hips are orange. Expanse of wings: 32 mm. Brazil. 
A. crassa Dogn. (37 i). The apex of the forewing is similarly cut off in a right angle as in marcata 
(37 a), but the venation is quite different, the two lowest subcostal veins of the forewing rising petioled from 
the third, in the the upper radial vein comes from the middle, in the $ from the apex of the accessory cell. 
Body greyish-black, long-haired, abdomen with more ochreous-yellow hair; palpi black. Forewings lustrous 
silvery white, with a broad blackish inner-marginal area; costa ochreous-yellow, towards the base black. Hind¬ 
wings white. On the under surface the forewings are grey with a yellow costal area. The $ is of a somewhat 
lighter colouring. Expanse of wings: 35 to 38 mm. Colombia (Quindiu, at an altitude of 3800 m). 
87. Genus: ^eagylla Hmps. 
Separated from the preceding genus by the absence of the accessory cell; on the forewing the two lowest 
subcostal veins rise, like in A. crassa, on a footstalk, from the latter the 3rd and 4th also rise petioled, the upper¬ 
most rising freely from the cell; the transverse vein is very strongly curved, above its lower angle the middle 
radial rises. On the under surface the $ shows in and behind the cell-end thick woolly hairing, at the proximal 
margin long hair being turned upward. Hindwings very broad; the two lower radial veins are on one footstalk 
with the upper median vein. The palpi exhibit hair which is turned downward; the anterior tibiae and femora 
show thick hair-tufts, the roughly haired abdomen long lateral anal tufts. Only 1 species: 
N. nevosa Dogn. (36 m) is a silvery white species well characterized by the peculiar shape of the 
wings. Head and thorax are tinted blackish-brownish; the hair-tufts on the legs and the hairing of the abdomen 
are yellow in the <J, like the costa of the forewing, white in the $. Costal area of the hindwing in the $ tinted 
blackish-brownish. Expanse of wings: 40 to 46 mm. Ecuador (Loja). 
88. Genus: Paragylla Hmps. 
Very closely allied to the preceding, but with much narrower forewings and still larger hindwings. 
Veins of the forewings and hairy spots like in Neagylla. On the hindwing the upper median vein rises 
before the cell-angle, the two lower radial veins petioled, the upper one with the subcostal vein unpetioled 
from the upper cell-angle. The palpi are not bearded, the anterior legs without any hair-tufts. The two species 
known of this genus are: 
P. amoureli Dogn. (36 m), a unicolorously orange-yellow insect with somewhat lighter hindwings. 
Expanse of wings: 44 mm. Ecuador. 
P. endophaea Dogn. (37 m) has whitish forewings, tinged grey in the cell-spaces; the inner-marginal 
area darker; costal margin towards the base blackish. Hindwing in the costal and marginal areas darkened.
