a darker colour, an oblique nebulous streak extends from a small costal spot behind the centre of the costal 
margin to behind the cell-end, where it is hardly noticeably angular and continued to the centre of the hind- 
margin. This specimen is from West Africa; the species has been described from Madagascar. 
Ph. monotonia Strd. (11 i). Expanse only about 19 mm; body and wings uni-coloured dark grey with 
a dull brownish tint, hindwing scarcely lighter than forewing. Cameroon. 
Pll. chota Swh. is still smaller (14 to 18 mm), likewise quite greyish-brown, but the forewing with 
a whitish costal margin. Teita in British East Africa; also known from Poona in India. 
Ph. atrescens Hmps. (11 i), from Cape Colony (Grahamstown), is the same, but the costa of the forewing 
with a thick yellow marginal stripe, the fringes of both wings honey-coloured, and the anal half of the hindwing 
lighter yellow. 
III. Subfamily: Hypsinae. 
The African Hypsinae, about 50 forms of which have been described, closely approximate the Indian 
Hypsinae. Particularly the species of Aganais, as a comparison with plate 27 of Vol. X shows, could be without 
difficulty inserted in their Indian allies in the group of the caricae- forms. Many Hypsinae belong also in Africa 
to the more common and conspicuous nocturnal lepidoptera. They are easily roused in daytime by a slight 
beating on the bushes, whereupon they fly about for a while in a somewhat Callimorpha- like flight, in order to 
alight again in the thicket. The real swarming-time, however, seems to be the night, as the Hypsinae number 
among those lepidoptera that come to the lights in the greatest numbers. According to Tessmann, Aganais 
speciosa, as well as Sarrothroceras came to the lantern in the evening and behaved exactly like certain Calli- 
morphinae which are taken flying in daytime and also at night on the lantern. 
As for the little number of larvae known, they have very little in common with the Lithosiinae to which 
the imagines were formerly always systematically annexed. According to Snellen there are certain similarities 
of the Hypsinae- larvae with Euchelia, but this can only refer to the belt-marking of some Indian species, such 
as Asota plana and Peridrome (Aganopis) orbicularis. His comparison with the larvae of Callimorpha seems 
to me to be more felicitous, since they exhibit in fact a certain resemblance with the larvae of Hypsinae, in 
the shape more than in the colouring. But some Hypsinae differ again from the larvae of Callimorpha in 
exhibiting a dorsal raising on the 4th and 11th rings, as for instance in Asota egens and caricae. 
We have already mentioned in Vol. VI, p. 422, that the Hypsinae of the eastern hemisphere in general 
correspond to the Anaxita of Tropical America (A. Seitz.) 
Hypsinae. 
Proboscis well developed. Palpi long, partly very long. In the forewing there is almost invariably an accessory cell, 
in the hindwing vein 8 rises separately, but it is mostly connected with the cell by a fillet. Separated from the genuine 
Arctiinae by the separate vein 8 in the hindwing, which only in some genera shortly touches the cell: from the Lyman- 
triidae by the presence of the proboscis. 
1. Genus: Aganais Bsd. 
Antennae of <$ long-combed. Third palpal joint very long. In the forewing veins 7 + 8 + 9 are forked, 
10 forming with 7 an accessory cell. In the hindwing veins 6 and 7 rise separately, 8 connected with the cell 
by a fillet. Type: borbonica Bsd,. 
A. speciosa Drury (17 a). Body orange-yellow, abdomen above often with black dots. Forewing 
at the base orange, in front as far as the base of vein 2, below the cell only half as far. Therein some black 
dots. The greatest part of the wing is dark brown, the veins therein finely yellow. Many forms derive their 
names from the colour of the hindwing. Typical speciosa (mostly $) has purely white hindwings and sometimes 
at the distal margin below vein 2 a black angle. — subretracta Wlcr. (= aphidas Hpffr.) (also mostly $) has 
uni-coloured yellow hindwings. — In undulifera Wlcr. the distal margin is broadly black, only towards the anal 
angle narrower. This form may have a white or yellow hindwing. — In baumanniana Karsch (17 a) the band 
very slightly recedes from the distal margin and often stops already at vein 4. Only known in the yellow form. 
— Very different is unicolor Bothsch. in which both wings are orange-yellow. By the forewing being more intensely 
dotted black and the distal margin being dark below it is separated from the otherwise similar borbonica -$. 
Probably conspicua Swh. is only a synonym of unicolor. 50 to 65 mm. Sierra Leone, Cameroon, Spanish Guinea, 
Natal. East Africa.
