E. niarpessa Drc. (50 b) is quite similar, the purple of the basal half more extensive; the small preapical marpcsm. 
spot larger. Likewise from Peru. 
E. parapessa Dgn. (50 b), from the same district as the preceding, has 3 / 4 of the forewings purple, / jarapesm. 
which colour extends at the costa broadly to the apex; only the marginal area, proximally bordered with an 
irregularly undulated, dark line, remains diaphanous. 
46. Genus: l*remolis Hmps. 
This genus of which 5 species are described has, like the last division of the Eupseudosoma, no uniform 
character owing to imitations from other genera. Remarkable is the small proboscis, the entirely rudimentary 
palpal terminal joint and above all the strong antennal teeth being thickened towards the ends. Porewing 
without an areola, the 1st subcostal vein branches off directly before the upper angle of the long, cuneiform 
cell of the forewing, the upper median with the lowest radial veins almost simultaneously from the lower cell- 
angle. The species seem not to be common. 
P. flavithorax Rothsch. (50 b). Parallel form of Prumala pyrostrota (44 i). The violettish-brown basal flavithorax. 
half is bordered with purple red and sinuately defined towards the yellow distal area in which there are 4 black 
dots between the veins. Abdomen vermilion. Amazon District. 
P. ridenda Dgn. (50 b) from Guiana is a form parallel to Eupseudosoma marpessa. The purple brown ridenda. 
of the basal half of the forewing extends as a costal band along the costal margin and bends round towards 
the margin at the apex in a hook. 
P. rhyssa Drc. (50 b) is quite similar, larger, the costal stripe in the apical half very dark blackish- rhyssa. 
brown, in the purple brown part of the wing whitish embedments surrounded by dark. Peru. 
P. seinirufa 1 Vkr. (50 b) is a large species resembling somewhat N. minerva (44 h); in the distal semirufa. 
half of the forewing a hyaline yellow band being very broad at the costa, ending only half as broad at the border, 
extends in front of the apex. In this band the veins are dark, the spaces between dotted red. Hindwings pink, 
towards the costa lighter. Panama and on the lower Amazon, as well as Peru. 
P. amaryllis Schs. is the smallest species. Still smaller than flavithorax (50 b). Head and thorax amaryllis. 
yellowy marked red. Forewings honey-coloured, the costal margin broadly red-brown; behind the cell, from 
this costal band a similarly red-brown, equally broad, straight band runs towards the proximal margin which 
it touches just at the anal angle. Hindwings yellow with a red hue; abdomen orange. 32 mm. Prom French 
Guiana. The type in the National Museum at Washington. 
47. Genus: Automolis Him. 
In this genus Hampson combines more than 12 other genera, with about 200 forms. The very name 
of this collective genus offers difficulties, since the typical species is doubtful, although the imago, larva, pupa 
and cocoon are figured. The single groups of the genus are certainly rather little allied to each other, as we see 
already from our superficial knowledge of their early stages. The first divisions show as larvae distinct relations 
to the Syntomids, but also to the PelochyM which are perhaps neither genuine Arctiids. The rutilus- group has 
unmistakable Halisidota- larvae, and others again emerge from larvae scarcely differing from the common 
Arctia- larval form provided with uniform hair-tufts. — In the way as the genus is at present composed, chief]} 
according to the venation being unreliable in the Arctiids, it contains the most heterogeneous formations: 
large and small, clumsy and slender species, angled and entire-margined forewings; small, stunted hindwings 
and also such showing no abnormity whatever; the venation itself also often deviates considerably; the hindwing 
has sometimes 7 (, sanguinolenta ) sometimes 8 ( ventralis ) veins; the subcostal vein of the hindwing may branch 
off far before the cell-end, or also only at it; furry spots may be absent or present in the <$, on one wing ( larissci) 
or on both ( semiopalina ). The antennae also vary in length. On the whole, the genus makes the impression 
of being an assortment of species rather remote from one another, which will be dissolved into a greater number 
of genera later on, when more females and larvae will be known. We must here restrict ourselves to mentioning 
the few characteristic marks being common to most of the species and arrange them one after another in such 
a way that the colourings may be denoted with but few' words and be developed one from another. 
Head rather large with thick round eyes; palpi rising, the terminal joint mostly short, often quite rudi¬ 
mentary, sometimes also long {semiopalina)-, proboscis always strong. On the forewing the lower median vein 
always rises far before the cell-end, the upper median vein emerges from the lower cell-angle and the uppermost
