B. specularis H.-Schaff. (43 1) is one of the largest species. The vitreous spot is strongly lobated 
towards the margin, surrounded by a distinct black, with a yellowish tone and only single vein-dots. From 
Mexico to Paraguay, nearly everywhere common. — rufescens Bothsch. are specimens from Peru, in which 
the grey colour of the forewings is more intensely toned red. — In the basal part of the forewing there are 
usually variable yellowish-red spots embedded. 
B. grisescens Bothsch. (43 1) is smaller, the forewings unicolorously slate-grey, the vitreous spot 
more white, but shaped as in specularis. But whilst the latter shows a variegated under surface of the forewing 
(a pink tinge in the basal area), the forewing is here grey beneath, with a small circumscribed red spot in the 
cell-end. Hindwings darkened grey (in specularis white). From Colombia to Paraguay and Peru. 
B. trigona Gri. (43 1). Forewings above yellowish-red, the vitreous spot almost straightly cut off 
towards the apex. Hindwings purely white. Beneath almost the whole forewing is of a beautiful pinkish-red. 
From Colorado and New Mexico to Costa Rica. -— steinbachi Bothsch. (43 1) lying before me from Tucuman 
and Salta in N.W.-Argentina, has the forewings intensely tinged yellowish, and the vitreous spot is distally 
very feebly undulated. — Sometimes we find also in this species large yellowish-red spots embedded near the 
base of the forewing; this isab. rubromaculata Bothsch. (43 m). — In schausiana Dyar (43 m) the vitreous spot 
has an obtuse tooth between veins 5 and 6, and the fringes of the forewings are speckled black. Mexico. 
B. philotera Drc. (43 m) is the smallest species. Dorsum of abdomen posteriorly black, forewings 
wooden brown with a small, very lobate vitreous spot. Hindwings smoky grey, semi-diaphanous, with black 
margins. Under surface still darker than the upper surface. Costa Rica. 
B. semiumbrata sp. n. (43 m) is larger than the preceding, forewings lighter brown, hindwings 
uniformly smoky-grey. Abdomen above not black. Easily recognizable by the under surface, where the cell 
of the forewing is filled up with vermilion, whereas philotera is beneath without any red except a hue on the 
proximal margin. 8 specimens (Coll. Fassl) in both sexes before me from Orosi, where it flies together with 
philotera. 
B. braziliensis Hmps. (= soror Dyar) (43 m). Forewings very similar to those of the preceding, 
though of a brighter red; hindwings white. South Brazil (Rio, Santos). 
B. myosticta Hmps. (= albipuncta Drc.) (43 m). One of the largest species, forewings dark violettish- 
brown. The vitreous spot begins already before the middle of the costa and exhibits a tooth mostly covered 
with-numerous small dots, between the veins 4 and 5 on the forewing. Hindwings silky white, at the border 
coloured grey, proximal margin rosy. Beneath the forewings are blackish-grey with light veins and a red cell, 
the hindwing has a double longitudinal spot at the base. Abdomen above red, beneath white. Mexico to Brazil 
and Peru. — crocea Schs. (= aroana Strd.) (44 a) is larger, the inner-marginal half of the forewing more red- 
brown; the hindwings of a purer white, the proximal margin of a broader and brighter pink colour; beneath 
the base of the hindwing has only 1 instead of 2 black longitudinal streaks. — In livida form. nov. (44 a) the 
wings and abdomen above are almost entirely covered with yellow; also beneath the ground of the forewing 
is pale ochreous-yellow. From Lino in Panama; in Coll. Fassl. — ockendeni Bothsch. from Peru is almost 
like crocea, but the inner-marginal half of the forewing is of a bright yolk-colour and the abdominal end-black. 
B. fumida Schs. (44 b) is only known to me from Hamfson’s figure copied here. Darker than crocea 
(44 a), particularly the dark smoky-grey the abdominal end with a subdorsal black spot. Forewing beneath 
quite dark smoky-grey, only in the traces of white above the proximal angle. Hindwing white with very 
little pink at the base of the proximal margin; the latter broadly suffused with smoky grey, in the. £ also along 
the border dark smoky-grey. Costa Rica. 
B. flavidorsata Hmps. (44 a) resembles the preceding species, particularly the vitreous spot is the 
same, but the forewings are more sepia-brown than reddish-or violettish-brown, and the abdomen and the 
proximal margin of the hindwing are yolk-coloured, the hindwings in the $ dark grey. Upper Amazon to Bolivia 
and Peru; not rare. 
B. albipuncta Schs. nec Drc. (44 a). Much smaller than the others, the hyaline spot is here particu¬ 
larly bright and shining, almost uniformly, parabolically bordered. The small white dot at the basal part of 
the median is often minute. Beneath not only the very bright hyaline spot of the forewing is opalescent, but 
also the surface of the hindwing shows an iridescent reflection. From Mexico through Central and South America 
to the south as far as Rio de Janeiro in the east and Ecuador in the west. 
g, 
detmcta. B. detracta sp. nov. (44 b) is by far the smallest species, the hyaline spot similar as in the precedin 
but distally irregularly bordered. The under surface does not show any red; here the forewing is uniformly 
dark drab except the shining spot and a light patch above the proximal margin. There are several quite similar 
specimens before me from the Coll. Fassl, all from Muzo in Colombia. 
26. Genus: Fasslia Dog 
u. 
This genus was established for a male butterfly unknown to me, captured by A. H. Fassl near Cali 
in Colombia in July. In Hampson’s Catalogue of the ,,Arctianae “, however, the genus is not mentioned, so
