P. pilumnia Stoll (— sordid us Wlcr.) (53 f). Head, thorax, and forewings light brown, the forewing 
densely strewn with blackish, particularly at the costa, cell-end and apex small blackish spots; hindwings 
diaphanous brown, abdomen black and banded dark pink. Costa Rica to the Amazon. 
65. Genus: Amina I o Wh\ 
This genus is very little homogeneous and is partly indistinct. The venation is very regular, offering 
no peculiarities whatever, the wings themselves show neither distortions nor scent-organs. The most conspicuous 
are the antennae being in some species very long and strongly combed, attaining a length of more than half 
the length of the costa. Across the base of the abdomen a long fleece of hair is spread. We come across all sizes, 
of medium size to large size and with colourings changing from dark brown and variegated to a diaphanous 
white; in their geographical range the species extend from the United States to South Brazil. 
Proboscis strong, palpi with a stunted terminal joint. Forewings sometimes with a pointed apex, with 
a narrow, cuneiform cell and an angled discocellular. The 1st subcostal vein branches off before the upper cell- 
angle, the 2nd together with the footstalk of the others from the cell-angle, from which also the uppermost- 
radial rises. The radials 2 and 3 come from the lower cell-angle, mostly — though apparently not always - 
together with the upper median vein. — The larvae, as far as they are known, are genuine bear-caterpillars, with 
tufted velvety hair, without any pencils or hair-brushes. Some species are common, but are almost invariably 
taken only at the light. 
A. tenerosa Dyar (53 f). The smallest species, all white, only the collar, the base of the costa and 
abdomen (except the base) yellow; abdomen above and laterally with a row of dots, Discovered by Roberto 
Mueller in Misantla in Mexico. 
A. tenera Hbn. (= collaris Fitch , antica Wlcr.) (53 f, g). Very much like the preceding, not so purely 
white, head and thorax as well as abdomen yellow, the latter with rows of black dots. Beneath the costal part 
of the forewing is sooty dark except the apical part. Atlantic states of North America. — Whilst in typical 
specimen the costal part of the forewing appears yellow, in the Californian form: sciurus B-sd. (= yosemitae 
Edw.) only the costal basal part is faintly lined yellowish, and the pro thorax is more greyish. — The grown-up 
larva is dull white with long, silky grey hair on tubercles being dotted black; stigmata black-curled; head flesh- 
coloured. It lives on Asclepias and Apocynum and the species is in some districts (e. g. in Carolina and Pennsyl¬ 
vania) not uncommon. 
A. eglenensis Clem. (— inopinatus Edw.) (53 g). Denominated by its resemblance to Euchaetias 
egle (39 f). £ dull greyish-brown with a yellow abdomen dotted black, and a white frons. In the 2 the wings 
are dull whitish with an orange-yellow costal stripe. — Larva reddish-ochreous with an orange-yellow head, 
black tubercles and silvery grey hair on them; on Asclepias tuberosum. Southern states of the eastern part 
of North America. 
A. insulata Wlcr. (= cadaverosa Grt., affinis Grt., aurat-a Btlr.) (53 g). Shape and size of eglenensis, 
but body and wings above unicolorously yellow. — aravaca Jord. does not differ exteriorly from insulata, but 
in the structure of the genitals. — Larva black, the 1st, 3rd, 7th and 9th segments brownish-red; across the 
dorsum a row of white spots, next to them thin subcostal streaks. Hair black, quite in front and behind inter¬ 
mixed with white hairs. Distributed from Florida through Mexico and Tropical America to the south as far 
as South Brazil and North Argentina, in some districts very common. 
A. cirphoides Rothsch. (53 g). Size of the preceding, but paler yellow, particularly in the disc of the 
forewing. The forewing is slightly brownish below an apical oblique streak and the fringes before the apical 
marginal half; also on the median, at the proximal margin and sometimes also above the submedian there is 
brownish scaling; discovered by Fassl in Colombia, on the Tolima, and the Quindiu Pass. 
A. bipunctata Wlcr. (53 g). Body and forewing oclrreous, densely tinged with red-brown, at the cell- 
end a darker mark; the hindwings lighter, more yellowish-white, somewhat diaphanous. Para. 
A. signata Wlcr. (53 g). The species which is said to originate from ,,Brazil 11 and is not before me, 
shows a superficial colorial resemblance to species of Hyperthaema, such as H. sanguineata (43 c). Body and 
forewings brick-red, watered by yellow, undulate transverse stripes, with a white spot encircled by black near 
the base, a similar antemargina-1 one, and small dark spots in and behind the cell. Hindwings dull whitish. 
A. constellata Dgn. (53 i). Repeats the colouring being widely distributed in South America of Tessellata 
sertata (42 f), Ochrodoti pronapides (43 a), different Carathis etc. Forewings dark sepia-brown with light yellow 
patches filled up with brown rings in the basal part and before the apex. Hindwings dark brown, cell and inner- 
marginal area lighter. Colombia.
