392 ARCTAC4YRTA: L8CHNOCAMPA. By Dr. A. , Seitz. 
71. Genus: Arctagyrta Hmps. 
This genus was established in 1901 for one of the smallest species having been before inserted in the 
Syntomid genus Agyrta. At once recognizable by the reduced subcostal system of the forewing showing only 3 
subcostal veins. Proboscis strong, palpi very thin. Wings rounded. 
A. nana 1 Ykr. (44 b). Black, all the wings with a hyaline centre and black margins which are broadest 
in the apical part. Amazon. The species is apparently not common, but it is also perhaps easily overlooked 
on account of its small size (expanse scarcely 2 cm) or also for its superficial similarity with numerous Syntomids 
such as Euagra eery mica (23 h). fenestra (23 i), Teucer car mania (20 a) etc. 
72. Genus: Iscliiiocampa Vide. 
The two dozen species belonging hereto mostly approximate the following Opharus, only some being 
considerably different, such as /. nigrivena, in which we may presume a mimicry of other genera ( Pachydota 
striata, 55 i). Proboscis strong, palpi, however, slender, delicate, with a comparatively long, porrect 
terminal joint. Antennae doubly combed, in most of the species not so long as in the allied Opharus, Amastus 
etc. In the forewing the 1st subcostal vein rises before the cell-end, from the angle itself rises the footstalk 
of the 2nd to 5th. from the same place with the upper radial. From the lower cell-angle rise the two other 
radials and the upper median vein likewise from one and the same spot. In the hindwing all the veins are 
present. 
1. griseola Rothsch. (55 f), the smallest species, is only the size of an Agoraea. Wings brown, densely 
powdered with an ashy grey, forewings with a black dot in the cell-end and a curved antemarginal transverse 
stripe sending forth on the submedian an obtuse tooth turned inward. From Jamaica, rare. 
I. adtneta Rothsch. (= lithosioides Rothsch. p. p.) (55 g) is somewhat larger than griseola , the ante- 
marginal stripe not curved, but through the middle extends another dark transverse band, and a third, curved 
one is before the middle. Venezuela. 
I. lithosioides Rothsch. (55 g). Forewings more ochreous, the 3 transverse bands are represented by 
curved, indistinctly defined nebulous stripes. Abdominal end orange-yellow. From Rio de Janeiro, rare. 
I. celer Schs. (55 f). Forewings more reddish-ochreous; the distal transverse stripe forms a longish 
W, the middle one being 8-sliaped, the proximal one interrupted on the submedian fold; hindwings dusted 
with grey. Likewise from 8outh Brazil (Novo Friburgo). 
I. sordida FI fir. (55 h). Forewings ochreous, very much strewn with black. Marking very much like 
that of the preceding; with a black dot in the cell-end. a W-shaped antemarginal stripe and a postmedian trans¬ 
verse shade only distinct at the proximal margin. 8ize of the preceding. Colombia, Bolivia and Peru. 
1. sordidior Rothsch. (55 f). Only the punctiform shade at the cell-end and the nebulous antemarginal 
stripe are distinct, otherwise the forewing is reddish-ochreous, striated and strewn with black. Hindwing at 
the border very brownish, otherwise diaphanous white: apex of abdomen orange-yellow. Peru. 
1. floccosa Rothsch. (55 g). Like sordidior, but the ground-colour of the forewing more greyish-yellow, 
and most purely and brightly covered with striae at the border, distally to the transverse stripe, proximally 
to it. however, very much with dark striae. Peru. 
1. ignava Dgn. (55 f). Wings much longer than in the preceding, body slim. Forewings reddish ochreous; 
a dark marginal nebulous stripe, an antemarginal one, and a postmedian one being somewhat curved. Colombia. 
1. perirrorata Hmps. (55 f). Forewings ochreous-yellow, densely dusted with blackish-brown, the 
small scales before the apex at the costa and right through the middle condensed to nebulous hands. Hindwings 
diaphanous bluish-white, the margins and apical part brownish. Thorax and abdominal end yellow, dorsum 
of abdomen blackish. Bolivia. 
I. remissa Dgn. (55 f). Wings white, the margins ochreous-yellow, the veins dark; in the foiewing 
at the cell-end a yellowish-brown demi-band and before the distal margin a transverse row of blackish streak- 
shaped and cap-shaped spots. Venezuela. 
I. hemihyala Hmps. 1= tolimensis Rothsch.) (55 g). Body blackish-brown with a yellow apex of 
the abdomen. Wings hyaline, the margins of the forewings yellowish-brown: in, below and behind the cell 
dark dots. Colombia to Peru.
