izecl by having the fore wing blackish only at the base and apex, otherwise suffused with orange-yellow; on the 
hindwing the marginal band is irrorated with yellow scales. 
ansorgei. A. ansorgei 8m. The forewing marked almost exactly as in conjuncta ; the hindwing above unicolorous 
orange-yellow, beneath clearer yellow with a nebulous grey median band; the light markings are sometimes 
cream-yellow and the subapical dots of the fore wing white. Hitherto only $$ known. British East Africa:

Second Subgroup. 
In the very characteristic arrangement of the light spots of the forewing and the reduction of the black dots in the basal 
part of the hindwing the species of this subgroup differ from those of the following. In the position of the spots in cellules 
I—6 of the forewing they approximate to the last two species of the preceding subgroup. Eltkingham places oreas in the 
servonci group, but hi my opinion it fits better in the same group as lycoa and johnstoni. 
A. lycoa is a very variable species nearly allied to johnstoni ; it differs from this in having the light 
basal or median area of the hindwing distally rounded or occasionally entirely absent. The fore wing has normally 
5 (—7) white or whitish spots, in the $ sometimes dull and very indistinct; the first is placed in 1 b close to 
the distal margin and is quite free and rounded or partly joined to the spot in 2, but never extends so far 
basad as the latter; the third is placed in 4 near to the distal margin quite free or touching the spot in 5; 
the spots in 5 and 6 are of equal length, joined to one another and to small spots in cellules 8 and 9; the 
lycoa. cell always unicolorous without spots. — lycoa Godt. both wings thinly scaled, semitransparent; spots of 
the forewing indistinct; basal area of the hindwing large, dull reddish yellow, distally rather sharply defined 
against the grey marginal band. wings thinly scaled, dark grey with distinct white markings; marginal band 
media, of the hindwing broad, not sharply defined. Sierra Leone to Nigeria. —- media Eltr. (57 a, as lycoa). <$. Spots 
of the forewing more distinct; hindwing in the middle somewhat tinged with reddish yellow but without di¬

The spot in 1 b of the forewing quite free; ground-colour in the $ yellowish grey; spots of the forewing small,

A. johnstoni, as already mentioned above, only differs from lycoa in not having the basal area of the hind¬ 
wing uniformly rounded distally, but more or less projecting or angled in cellule 4; this character is especially 
pronounced on the under surface. The species is no less variable than lycoa ; the light spots of the fore wing are 
light yellow or white and the spot in 1 b is placed quite free; the forms are connected by intermediates. Pal- 
johnstoni. pus yellowish. — johnstoni Godm. (57 d). The black ground-colour of the forewing above is restricted to the 
base and the distal margin, being covered in the middle by a very broad orange-yellow' band, irregularly defined 
distally, which reaches the light yellow spots, but extends scarcely or not at all beyond them; hindwing with 
fulvescens. white basal area and broad black marginal band. German and British East Africa. — f. fulvescens Oberth. Both 
wings above pale orange-yellow as far as the narrow marginal band, which has an almost uniform breadth of 
2—3 mm.; spots of the forewing and basal area of the hindwing somewhat lighter yellow. German and British 
East Africa. — The following forms agree with one another in having the ground-colour of the fore wing above 
confusa. uniform black-brown without orange-yellow median band. — f. confusa Rogenh. Spots of the forewing white; 
basal area of the hindwing light ochre-yellow with broad black marginal band as in the type-form; is confusingly 
similar to f. fallax of lycoa and commoner than the type-form. Nyassaland to British East Africa and Uganda. 
flavescens. — f. flavescens Oberth. Both the spots of the forewing and the basal area of the hindwing light ochre-yellow; 
semialbes- otherwise similar to f. confusa and with the same distribution. —- f. semialbescens Oberth. only differs from 
cenSm confusa in having the basal area of the hindwing brown-yellow. Nyassaland and German East Africa. — f.

butleri. A. butleri Auriv. (= toruna Srn.). This species also is regarded by Eltringham as a form of johnstoni. 
Although the male genitalia are formed as in johnstoni it seems to me better for the present and until transi¬ 
tional forms have been discovered to cite butleri as a separate species, as it differs from johnstoni in the black
