of the lower cell-angle, the uppermost subcostal vein anastomoses with the costal. Hindwings broad, costal 
margin very convex, apex rounded; the margin runs almost in a straight line to the proximal angle. In the 
cell of the a large scent-scale spot; the middle radial rises separately from the lower one above the cell-angle, 
the upper radial anastomosing with the subcostal vein. Only 1 small species. 
A. crocea Schs. (37 1). Head and thorax lilac-grey; the abdomen like the wings yellowish-white, the 
proximal margin of the forewing broadly lilac grey; on the hindwing a stripe of long yellow hair runs along 
on the median. Expanse of wings: 29 mm. Costa Rica. 
83. Genus: Tricliaresa Hmps. 
Distinguished from the preceding genus by the somewhat rounder shape of the wings and, above all, 
by the lower radial veins being rather long petioled on all the wings; on the hindwing the upper radial vein 
is present separately. The $ exhibits on the forewing beneath hairy fringes in a costal fold, and long erect 
hair along the submedian fold, on the hindwing above in the cell-end a tuft of fluffy hair. 
T. fulvilaniata Dogn. (37 1) is on its body white, with a brownish hue, the antennae more red-yellow. 
Forewings silvery white, at the proximal margin light brown, the costal margin towards the base blackened; 
hindwing white with a red-yellow woolly hair-spot. Expanse of wings: 28 mm. Panama. 
84. Genus: lflyg>c‘i*f isagylla Hmps. 
Likewise closely allied to the preceding genera. Forewings narrower, with a narrow discocellular, 
beneath without any hair; a small accessory cell is present and is produced by the 3rd subcostal vein anasto¬ 
mosing with the 4th; the 1st subcostal vein is sepa ated. Hindwings more rounded, the two lower radials on 
a short pedicle; in and behind the cell-end of the J a large scent-scale spot. On the last abdominal ring of the 
$ very long lateral hair-tufts. Contains but 1 species. 
H. mira Btlr. (36 i). White, on its body, costal margin and proximal margin of the forewing tinged 
lilac grey. The scent-spot of the hindwing red-brown. Expanse of wings: 26 mm. Amazon District. 
85. Genus: Metagylla Hmps. 
Only 1 species. Distinguished from the preceding genus by the palpi being provided with hair turned 
downward, and still longer hairing, also on the dorsum of the anal segment of the <$. The venation is likewise 
very similar; on the forewing the upper median vein is removed to the cell-angle, so that it rises from the same 
place with the two lower radials; the accessory cell is absent. On the hindwing the upper median vein is on 
a short pedicle with the two lower radials. The other venation and the scent-spot as in Hyperthagylla. 
M. miroides Hmps. (36 i) is coloured almost exactly like mira, only the dorsal anal tuft is reddish- 
yellow, the lateral ones being blackish-brown. The red-brown scent-spot is distally bordered with ochreous-yellow. 
Expanse of wings: 28 mm. Costa Rica. 
86. Gattung: Agylla Wkr. 
Proboscis developed; the erect palpi do not reach the vertex; posterior tarsi with spurs of medium 
length; abdomen at the base covered with rough hair. Forewings rather narrow; the lower median vein rises 
close behind the middle of the cell, the upper one rather far before the lower angle; the two lower radial veins 
either on a short footstalk, or from the cell-angle; the upper radial comes out of the upper cell-angle or the 
accessory cell which is produced by the 3rd subcostal vein anastomosing with the 4th; the uppermost subcostal 
vein separately from the cell and terminating in to the costal margin. On the hindwing the upper median vein 
rises from the cell-angle or close before it; the two lower radials like on the forewing; also the upper one is either 
petioled with the subcostal or it comes separately out of the cell-angle. As to further particulars about this 
genus comp. Vol. II, p. 64, and Vol. X, p. 199. 
A large genus, distributed in all parts of the globe, except Europe. The American representatives are 
preferably coloured white, often with a darkened proximal margin of the forewing. Many species are distinguished 
by secondary sexual marks, mostly consisting in the °f scent-scale spots or varied hairing. <$ antennae 
either doubly short-combed, or also with ciliary bristles. Of late a great number of species have been described, 
all of which are mostly very much like each other and make it difficult to define them; this is particularly the 
case in the $9, since the can be better distinguished by the various hairy spots on the wings or tufts 
on the abdomen etc. In the neotropical region they represent our Lithosia which they also resemble on the 
whole in their habits. Like them, they have the narrow long forewings turned round the mostly much too 
large hindwings being folded together and round the abdomen. The species come to the lamp.
