from the cell to the proximal margin, behind the middle an irregular band, besides a cell-end spot. On the 
hindwing the submedian fold is tinged orange. Brazil, from the Amazon to South Brazil. 
B. eleuthera Stoll (42 h). Size and shape of the preceding, of a paler yellow, the forewing strewn 
with brown atoms and whitish crescents, the latter bordered darker and intermixed with roundish spots. Before 
the middle an indistinct, dark transverse band forking towards the costa. Abdomen and hindwing with a 
drill rosy-red tinge. From Surinam to Bolivia; apparently wide-spread, but not common. 
B. eleutlieroides Bothsch. Expanse: 25 (^) to 30 (§) mm; similar to eleuthera , but the wings much 
narrower, all the brown markings wider, more irregular, the lines bordering on the markings not so distinct. 
Surinam to Peru. 
B. flavescens Bothsch. (42 h) is rather small, pale sulphurous yellow, with very irregular brown 
markings and between them some white guttiform spots encircled dark. Hindwing pale yellow, only in the 
inner-marginal half with a faint reddish-tinge. Abdomen above tinted yellowish-red. Described according 
to 1 from Fonte Boa on the Amazon. 
B. affinis Bothsch. likewise from Fonte Boa, resembles flavescens, but the forewing with a net of 
fine brown markings, 3 dark brown costal spots and an interrupted, brown, antemedian transverse band; there 
are also brown spots above the proximal margin, before the apex and behind the middle; abdomen of a bright 
rosy-red. 
B. schausi Bothsch. is the most closely allied to marmorea (42 g): on the forewing the ground-colour 
is a dull violettish-brown, crossed by numerous, irregular rows of yellow, red-centred rings. Hindwings pale 
and somewhat diaphanous yellowish-pink, abdomen pink. From Trinidad through Venezuela and Colombia 
to the Amazon. 
B. sannionis Bothsch. from the Upper Amazon has golden yellow head and tegulae, the latter 
with a black centre; palpi carmine, outside bordered with brown. Patagia and thorax brown, speckled carmine 
and yellow. Abdomen carmine, the last segment golden yellow. Forewing red-brown, faintly strewn with yellow; 
base yellow with 2 carmine dots; hereafter a transverse band of carmine spots bordered with yellow. Discal 
and postdiscal area with 3 or 4 irregular macular bands bordered with yellow; in the dark marginal line a series 
of small, carmine dots. Hindwings transparent rosy, washed over with golden yellowish. Expanse scarcely 
more than 20 mm. 
B. venata Bothsch. Head and thorax buff with paler and red spots. Abdomen dirty brick-red. Fore¬ 
wings buff, all the veins marked with a broad light brick-red. Basal half of forewing irregularly spotted dark 
brown and dotted black; a postmedian, dark brown transverse line. At the border and before it rows of small 
dark internerval spots. Hindwings rosy-red. Expanse of wings: 32 mm. Surinam. — This species structurally 
deviates more from the other Baritius, for which reason H amp son established the genus Haemaphlebici for 
it. — To this belongs also 
B. strigata Jones (43 b). Size about that of marmorea (42 g); the forewings buff with numerous red 
transverse bands and lines, as well as small spots in the marginal area; the hindwing in the costal half ochreous 
yellowish, in the anal half pale pink. From Santos in South Brazil. 
11. Genus: fctyutareiia Hmps. 
Hereto belong but few, similar species distributed from the Amazon to the north as far as Surinam, 
Venezuela, and Trinidad. In their exterior they somewhat recall a small Halisidota and show a plain, pale 
yellow or brownish colouring with a fine undulate marking on the forewing. Antennae, proboscis and palpi 
as in Baritius from which they chiefly differ by the narrower cells of all the wings, particularly of the forewings, 
and by the absence of the subcostal vein of the hindwing. In the latter respect they resemble the Tricypha, 
but these deviate from them and all the other Arctiids by the entirely distorted system of the subcostal veins 
on the male forewings. 
S. oenone Btlr. (42 h). Right across the pale-yellow, rather pointed forewing extends a number of 
mostly paired, reddish-yellow streaks, between which there are subcostally some irregular dots. From Vene¬ 
zuela and Guiana through South America as far as Brazil and Ecuador. 
S. fasciata Bothsch. (42 h) from Fonte Boa on the Amazon resembles oenone in size and shape, but 
it has across the pale yellow forewing broad, greyish-brown transverse bands. 
S. russus Bothsch. has light brown head, thorax and forewings, the latter crossed by numerous 
brown, partly irregular zig-zag lines. Before and through the middle extends one broader zig-zag band each. 
Size and shape like tire following. Unknown to me; patria not stated.
