together. antennae usually shorter than the thorax, rather feeble, bipectinate, in the 5 plain. The species 
are distinguished by an uncommon variability, especially in the males. 
Type: L. achelous Or. 
L. achelous Or. (— obliqua Wkr., <$ albigutta Wkr.) (119 c) ochreous or reddish ochreous, strewn achelous. 
with a scarcely darker colour, smoothly scaled, with a hardly traceable somewhat greyer antemedian line 
forming distally convex bows in and below the cell; in the upper and lower cell-angles one white spot each: 
the purple brown or black almost straight postmedian line from shortly before the apex to the centre of the 
inner margin, inwardly bordered with whitish or grey, occasionally before it yet a grey parallel line; subterminal 
faint grey irregular shading, projecting between 2 and 4. Hindwing with a straight grey median line and a 
hardly traceable subterminal shadow. Beneath lighter, more coarsely speckled, with 2 small blackish, light- 
ringed discal spots on each wing; hindwing especially costally spotted grey with a large apical spot and a 
whitish undulate subterminal line. $ more thinly scaled, lighter and more greyish-brown, in the marginal 
area somewhat darker, with a distinct subterminal shading. Widely distributed: Brazil, Bolivia, Antilles, 
vulpina /. n. (119 c) is the name of a particularly large, reddish ochreous form, from Novo Friburgo, with a vulpina. 
strong black double line filled with lead-grey, and intense blackish subterminal shading. Type in the Berlin 
Museum. — carnica Schs. is very similar, but of a flesh-coloured or carmine pink ground colour and onlv faint carnicu. 
subterminal shading; the oblicpie line is here also double and filled with grey, the upper one of the two discal 
spots blackish, only the lower one white. Under surface light brownish-red with a broad marginal brightening, 
hindwing with a black, white-edged discal spot. Petropolis; Sa. Catharina. 
L. cynira Gr. (= eJectra Drc.) (119 b, c) has somewhat broad and obtuse wings coarsely strewn with cynirci. 
blackish, otherwise very similar and just as variable, the two white discal spots mostly connected by a curved 
or angular blackish streak or rarely situate in an oval blackish spot. The $ is more grey or reddish-brown, with 
a more distinct light dentate-undulate subterminal line. - concordia Drc. are somewhat deeper orange males concurdia. 
with a more distinct subterminal shading. Mexico to Guiana: probably only the northern form of achelous. 
L. submacula Wkr. (= apicalis Wkr., falcata Wkr.) (119 d) differs in the <$ in the higher and shorter sulmacula. 
shape of the wings. Apex of forewing slightly falcate. Distal margin somewhat concave, hindwing with a 
slight angle below 7 the centre. Light reddish-brown, strewn darker, with 2 blackish transverse lines, the anterior 
one forming 2 bows, the posterior line from the apex to the distal third of the inner margin; discal spot oval, 
blackish with one or two faint whitish centres above and beneath: behind the feeble subterminal shading some 
small light yellowish spots; hinclwdng the same, the yellowish small subterminal spots very prominent. $ in 
the marginal area on both wings darkened brown, otherwise the same. Venezuela to Peru and Brazil. 
L. diabolus (Maass. i.l.) sp. n. (119 d). Shape of wings the most similar to submacula and almost diabolu-s. 
similar to that of small Copaxa. (Monotonously blackish-brown, strewn a little with lead colour, without the 
antemedian line, only in the lower cell angle a small white spot; the oblique line of the same course as in 
submacula, slightly darker, inwards bordered with lead colour; subterminal shading hardly marked. Beneath 
lighter and more brownish with a slightly darker oblicpie stripe and small, lighter-ringed discal spots. According 
to 2 from Cayenne, type in the Berlin Museum; a third $, likewise from Cayenne, is smaller and more 
reddish-brown; another from Teffe (Amazons), in the Senckenberg Museum, is also somewhat browner and 
has a very distinct straight antemedian line on the hindwing. Apex of forewing somewhat less falcate. 
L. abnegata Wkr. has unfortunately remained unknown to me. abnegata. 
13. Genus: Perlga Wkr. 
Scarcely different from Lonomia ; apex of forewing somewhat more pointed and distal margin straighter, 
anterior angle of hindwing somewhat angular. Palpi and antennae somewhat longer. On the hind wing 6 and 7 
rise still nearer together than in Lonomia. Only 2 species: 
Type: P. circumstans Wkr. 
P. circumsfans Wkr. (= cluacina L>rc.) (119 c!) is just as variable as the Lonomia species. straw- circum- 
coloured yellowish, orange, brick-red or brown, more or less strewn with blackish, with blackish transverse si 
lines, the anterior one undulate or only feebly bent, the posterior one straight, in the darker forms inwards 
bordered with a lighter colour; behind it an undulate subterminal line; at the cell end 2 blackish, often white- 
pupilled small spots which are mostly connected by a curved streak. Hindwing with a curved antemedian 
line, a stronger straight median line, and a dentate-undulate subterminal line. $ more thinly scaled and of a 
light ash-grey colour. Panama to Brazil.
