violettish-blue spots; apical spot bilobate. Guiana to Brazil. The specimen figured e Coll. Niepelt, from 
Western Colombia, is remarkably dark and variegated. 
A. sylla Cr. is extraordinarily near to hercules; the shape of the wings is rounder, the apex less produced, 
the hinclwing more rounded, without the concave indenture below the apex; darker brown, the discal ring finer, 
absent altogether on the hindwing; subterminal line broader, more creamy, the slate-blue spots behind it 
narrower; the black spot below the red-edged apical spot is much smaller. From Guiana (Surinam). — f. 
pelias Jord. is lighter, the $ coloured almost like meander ; the reddish-yellow subterminal line is still broader, 
the brown marginal area likewise broader, as broad as in liercules, the black spot below the apex as large as in 
hercules. Matto Grosso (Cuyaba). 
A. alcmene sp.n. (124 a) is smaller, darker chocolate brown, the postmedian band bordered inside in 
the lower half by the antemedian line which is rectangularly flawed on the median; subterminal line scarcely 
lighter than the brown ground, forming a uniform bow in the middle, projecting rectangularly on the inner- 
marginal vein. Hindwing rounded, costal margin much longer than the inner margin. Also very similar to 
xanthopus. According to 2 $$ from Novo Friburgo, type in the Berlin Museum. 
A. xanthopus Wkr. (124b) is smaller than the preceding species, the ground of the wings lighter, the 
subterminal line forming a hardly noticeable angle in the large bow on 3 is very contrastingly brownish-white, 
whilst in alcmene it is not or scarcely lighter than the ground; behind it, on the hindwing, follows a lilac grey 
band of spots, behind it a band of red-brown spots, both separated by finely strewn bluish-white scales. 
Distributed in Brazil and Argentina. In the Berlin Museum there is a very light bone-white specimen intensely 
strewn with brown, from Parana. d'orbignyana Bouv. is a transition-form to the following species. Forewing 
as in xanthopus, hindwing coloured like that of angulatus. Bolivia. Larva dark grey speckled with brown, 
with a yellow lateral line and a black and yellow neck-shield and anal end; young larva with 2 filiform horns 
on the 2nd ring and a similar one on the penultimate ring of half the length of the body, adult larva without 
horns. It lives on “racapicho”: Urena sinuata, a shrub with burry fruits. 
A, angulatus Bouv. (124 b) is still smaller, more delicate and variegated, the $ antennae decidedly 
longer combed; the lilac apical spot is one-pointed, not bilobate as in the preceding species, the subterminal 
line on the hindwing much more notched, especially angular on 3 and 4. Brazil; apparently a common species. 
A. meander Wkr. (124 b) is a large reddish loam-coloured species, the $ being almost reddish brick- 
coloured, the wings not strewn at all; behind the yellowish-white subterminal which is especially broad on the 
hindwing there are red-brown, black-centred ornaments bordered by thick high black bows; below the apical 
spot which is suffused with pinkish-red there are 2 thick black spots. An apparently very rare species from 
Brazil. In the Berlin Museum there is a beautiful couple. 
A. pandora King (124 c) is allied to meander , smaller, lighter, without the reddish brick-tinge, very 
intensely strewn with blackish-brown, otherwise very similarly marked, though the antemedian line of the 
forewing is only present in the lower half. Brazil (Minas Geraes). 
A. cymonia Rothsch. (125c) differs from the armida-grovrp in the darker coffee-brown ground-colour 
and a thick oval discal ring; the postmedian band is narrow, the subterminal line whiter, the black ornamental 
bows or sagittate spots distally scaled bluish-white. with a feeble tail as in armida. Peru. 
A. polyodonta Jord. (124 c, 125 a) to a certain degree forms the transition from pandora to the following 
armida- group. Somewhat smaller than pandora, relatively sparsely scaled, the apex of the forewing slightly 
produced; the antemedian line is x’emoved near to the discal spot and connected with it by a dent on the 
median vein, often forming an entire ring; postmedian band very dark, the subterminal line behind it very 
broad, purely white, with very strong, long black notches behind it. Only known from Mexico (Cuernavaca, 
Jalisco, Guerrero, Zacualpan). West-Mexican specimens are strewn with a darker greyish-black. 
A. cassandra Cr. (134 b) is a questionable species; judging from a $ kindly handed by Mr. Bang-Haas 
and corresponding well with Cramers’ figure, it is to be separated from armida. Of a yellowish tinge, sparsely 
scaled, like polyodonta ; base, cell and the part of the median area as far as the postmedian line and below 
as far as vein 2 intensely strewn white; the marginal area is remarkably darker than the preceding subterminal 
band which ends taperingly at the inner margin in both wings. Larva, according to Cramer, yellow with many 
black streak-markings and spots with an orange head, ventral and anal feet, the young larva in front with 4 
horns, behind with one black thin horn. Guiana and Colombia (Muzo). 
A. armida Cr. (124 c, 125 a) is very similar, greyer; more densely scaled, the broad subterminal band 
darker brown than the somewhat more reddish marginal area, the subterminal line situate behind it is purely 
white only above the inner margin, in cassandra uniformly white almost in its whole extent. The qR are mostly
