80. Genus: Macroptila Dogn. 
The 7 species known hitherto of this genus approximate the Agijlla already by the shape and thereby 
our Lithosia; the forewings are almost lancet-shaped, and the hindwings in some species, such as antonia and 
extensa extraordinarily large. Proboscis developed. Palpi erect, beneath covered with hair which is turned 
downward. On the long, narrow forewing the lower median vein rises behind the middle of the cell; the upper 
one before the cell-angle; the two lower radial veins are petioled, the upper one either from the upper cell-angle 
or from below it; the uppermost subcostal vein is curved and terminates into the costal vein; in the $ the costal 
margin beneath is hairy. Hindwings very broad and round; the lower median vein from the middle of the 
cell; the upper one close in front of the lower angle; the two lower radial veins petioled or unpetioled, similar 
as the upper one with the subcostal. 
M. monstralis Schs. (36 i). Head and thorax grey, forehead brown; abdomen whitish; legs white, monstralis. 
anterior tibiae above with ochreous-yellow hair. Forewings light grey, towards the proximal margin darker 
grey, costal margin and the veins above the median veins white; costa itself ochreous-yellow. Hindwings in 
the costal-marginal half light brown, towards the proximal margin white; margin dark grey from the lower 
median vein to the apex. In the base of the cell a small scent-scale spot. The costal margin of the forewing 
is straight and exhibits before the apex a small, lobular embayment. Expanse of wings: 30 mm. Costa Rica. 
M. antonia Dogn. Body yellowish-white. Forewing of the S in the disc with a scent-scale spot, at antonia. 
the lower cell-end a tuft, of long white hair, lustrous silvery white, costa finely ochreous yellow. Hindwings 
above white. Under surface white, in the marginal area of the forewing and in the costal half of the hindwing 
with a grey tinge. In the $ also the proximal margin of the forewing is above tinged grey. Expanse of 
wings: S 38 to 40 mm, $ 31 to 33 mm. Colombia. 
M. crinada Dogn. (36 i) has a greyish-brown head and thorax; antennae red-yellow; abdomen yellowish crinada. 
white with an orange anal tuft. The white forewings are tinged purple grey towards the proximal margin and 
exhibit a similar stripe above the lower median vein; costal margin yellowish, towards the base darkened. 
Hindwings yellowish-white, towards the margin tinged greyish-brown, in the S with a large scent-scale spot 
in the costal area. The $ is of a purer white with a decidedly darker inner-marginal band. Expanse of wings: 
44 mm. E mi ad or. 
M. laniata Dogn. (371). Body white, tinged greyish-brown; antennae, legs, last abdominal ring, and laniata. 
ventral side ochreous-yellowish. Forewings silvery white, dusted darker; the S exhibits beneath in the disc 
tufts of very long yellowish-white hairy scales. Hindwing in the costal half greyish-brown, in the inner-marginal 
half white. Expanse of wings: 34 mm. Ecuador. 
M. nubecula Schs. (37 1) deviates from the other species by the narrower cell of the forewing and curved nubecula. 
median ; the uppermost radial vein rises far below the upper cell-angle. The hindwing exhibits in the a large, 
brown scent-scale spot in the cell; the upper median vein is petioled with the lower radial veins; the costal margin 
is concavely excised before the apex. Head and thorax are lilac grey, the abdomen reddish-white. Forewings 
in the costal-marginal half silvery white, delicately laid on with yellow-reddish, below the cell lilac grey, with 
a yellow-reddish hue. Hindwings yellow-reddish white, towards the apex dusted grey. Expanse of wings: 
32 mm. Costa Rica (Sixola, Tuis, Esperanza). 
M. extensa Rothsch. (37 1) is described according to 1 female specimen. Body light red-brown, mixed extensa. 
with whitish. Forewings silvery white, proximal margin tinged reddish-brown. Expanse of wings: 42 mm. Peru. 
M. fuscilaniata Hmps. (37 1) is distinguished by very broad wings. Body ochreous-yellow, on the fuscilania- 
head and thorax brownish. The ochreous-yellowish forewings are tinged blackish-brown at the proximal margin, 
costal margin towards the base blackened. Hindwings ochreous-yellow, towards the costal margin brownish. 
Beneath the forewings exhibit above the proximal margin a blackish-brown scent-spot, above it yellow spatulate 
scales. The $ has plain white wings with a brownish proximal margin. Expanse of wings: S' 40, $ 46 mm. 
Colombia. 
81. Genus: Mypareva Hmps. 
Proboscis well developed. Palpi rather short, covered with hair turned downward; S antennae at the 
base thickened, with long ciliary bristles. Anterior femora long-haired. The venation differs little from that 
of the preceding genus; the two upper subcostal veins of the forewing rise freely from the cell and run into 
the costal margin. The upper radial vein and the subcostal of the hindwing are unpetioled. The S 
exhibits beneath on the forewing long hair in the cell and in the submedian space, and a large pouch in 
the basal part of the median of the hindwing. Only 1 species is known: 
H. pogonoda Hmps. (= laticilia Drc. part.) (37 1). Body and wings white, the head ochreous yellow, pogonoda. 
Forewings at the costal margin brownish, at the proximal margin dusted more purple blackish, in the $ more 
intensely than in the S- I 11 the latter the hair on the under surface are ochreous-yellow. Expanse of wings: 
32 mm. Distributed from Mexico through Guatemala, Panama as far as Guiana (Cayenne). 
82. Genus : Apt ilosfa Schs. 
Proboscis developed. Antennae in the S with short cilia. Abdomen with rough hair. Forewings rather 
broad. Venation similar as in the preceding; on the forewing the two lower radial veins rise from the same place
