the posterior line outside bordered with whitish. Hindwing likewise in the central area dusted with dark, with 
blackish faded transverse lines. Easily discernible by the angular and cut-out hindwings. Colombia. 
A. zattu Schs. (49 m). Forewing pointed, slightly cut out below the apex, grey, strewn with brown, zattu. 
the light brown costal margin as far as the centre dark, from there to the apex white-spotted, with fine curved 
brownish transverse lines, the posterior line thicker, forming an outward angle right above the anal angle; 
along the distal margin a whitish nebulous stripe. Hindwing brown, at the distal margin dusted with grey, 
with fine black-scaled transverse lines. Costa-Rica. 
A. truncata Hmps. (49 m) shows the forewing and hindwing somewhat cut out below the apex. Forewing iruncata. 
whitish, tinted and strewn with brown, with fine blackish transverse lines being dotted deeper black, and a 
whitish discoidal spot; before the black marginal dots there is a whitish line. Hindwing the same and besides 
with a white subterminal line on both sides finely bordered with black. Panama. 
A. umber Dyar (49 m) is closely allied to truncata, forewing brown, strewn with whitish, with almost umber. 
obliterated markings, only single small darker dots connected by feeble yellowish lines instead of the usual 
transverse lines, before the black marginal dots with a white line; hindwing with a feebly orange-tinted median 
band, in the greyer distal portion 2 fine blackish lines and a white marginal line. Panama. 
A. mela Dyar (49 m) has shorter palpi and a feeble yellow proboscis, the narrow forewing is entirely mela. 
margined with a sharp apex, the two lower radial branches are stalked; forewing grey with a black, thrice 
interrupted costal margin, a small black discal spot and marginal dots, instead of the interior transverse line 
3 red-brown dots, with 4 feeble brownish postmedian transverse lines. Hindwing with a black subbasal line, 
a brown postmedian line and 2 subterminal lines; the first abdominal ring is black, the rest grey. Panama. 
A. enona Drc. (49 m). The orange forewing is dusted with red-brown in the costal half, with very feeble enona. 
lighter antemedian and postmedian transverse lines, and brownish subterminal streaks. Hindwing yellow 
with a red-brown basal spot and feeble faded orange median and subterminal bands. Mexico to Brazil. 
A. flavipars Dyar (49 m) is light yellow on the forewing with a broad purple grey costal half, between flavipars. 
the two colours scaled orange. The small hindwing is yellow, at the base purple, then red and orange scales. 
From Panama. 
A. celenna Drc. has white forewings dusted red-brown and dark brown in the costal-marginal area, celenna. 
with punctiform black transverse lines, the posterior line more red-brown, besides a small white discoidal luna; 
at the margin there are above black dots, and red-brown dots in the white area. Hindwing white with red- 
brown transverse lines, the posterior line interrupted with a small black spot at the anal margin. Expanse of 
wings: 18 mm. Guatemala, Panama. 
A. atripuncta Hmps. (49 m). Forewing whitish, strewn and dusted with red-brown, costal area darker atripuncta. 
brown with feeble whitish transverse lines and discal dot with a black dot in front of it; the white subterminal 
line is inside bordered by faded black streaks, outside by black dots, at the anal angle there is a thicker black 
dot. Hindwing similarly coloured with a curved red-brown median line and a black anal-marginal dot, a white 
subterminal line with single black small dots behind it. Brazil. 
A. infantilis Schs. (50 a) may belong to lycaugesia and is grey on body and wings, the latter traversed infantilis. 
by 4 pinkish-brown nebulous lines, in the anterior and posterior ones on the forewing there are single black 
scales accumulated; at the margin black dots. Costa-Rica. 
A. lycaugesia Hmps. (50 a) exhibits on the light reddish brown forewing a feeble, very oblique, somewhat lycaugesia. 
dentate white posterior transverse line and a tiny white discoidal luna beside 2 black costal-marginal dots. 
Hindwing somewhat deeper red-brown with 2 feeble oblique red-brown antemedian lines and a whitish band 
between them, as well as a narrow white postmedian band which is analwards inside edged with black; in front 
of the black marginal dots a white line. Amazons. 
A. costipuncta Hmps. is somewhat similar to lycaugesia, but it has besides small black spots in the costipunda. 
middle and at the end of the cell, a faded brown median line extends from a black costal-marginal dot to the 
inner margin, the marginal half of the costal margin is spotted brown, behind a darker postmedian line dark 
irroration; the waved line is whitish, in the middle finely dentate. The similarly coloured hindwing shows an 
indistinct posterior transverse line outside bordered with whitish, as well as a subterminal row of whitish lunulae. 
Expanse of wings: 16 mm. Peru (Cuzco). 
6. Genus : Araeoptera Hmps. 
Chiefly distinguished from Acidalioides by all the 5 subcostal branches having a joint stalk, and by 
the well developed proboscis. Abdomen only on the last rings with very short small tufts. Most of the species 
are Indian (cf. Vol. XI), but also a few Tropical American species have been described, which are externally 
very similar to the preceding genus.
