at the margin in the centre with a large, jet-black marginal spot with metallic scales and being inwards bordered 
with yellowish-red. The discal spots of the forewing and 1 b and 7 of the hindwing as well as the 4 subbasal 
dots are jet-black and punctiform. The discal spots 1 c to 6 of the hindwing are of the ground-colour. All 
the spots beneath are margined with white. Black marginal spots broadly bordered with yellow are also 
in the areas 2 and 3 of the hindwing.

bluish-grey reflection. — Wings above blackish-brown without a bluish reflection. South Africa to the 
north as far as the Damaraland, East Africa as far as Abyssinia and Nubia, Arabia, Sokotra. 
C. alberta Btlr. was described as a Chilades, but it most probably does not belong to this group, alberta. 
„<$. Wings above ash-brown with a bright violet reflection; the margins and veins as well as the discocellular 
spots and fringes are smoke-brown; hindwing with smoke-brown marginal spots, the penultimate (in area 2) 
being bordered with blackish and the three last (in 1 c to 3) towards the margin bordered with white; the 
fringes of the forewing towards the anal angle and those of the hindwing with a white basal line; body normal; 
under surface almost as in Euchrysops cyclopteris, except that the three last (in 1 c to 3) marginal spots of the 
hindwing are inwards bordered by orange spots; the last spot is short and linear. — The $ is larger and bluer 
than the with a well defined dark marginal band and discocellular spot of the forewing; the costal margin 
is in both wings broadly darkened; hindwing above with large orange bows within the three last marginal 
spots (in 1 c to 3); under surface more whitish than in the E with somewhat smaller and more indistinct 
markings. Expanse of wings: 27 to 30 mm.“ Equatorial Africa. — The. description of the $ exactly agrees with 
that of C. koaena Strd. (1911). 
Twentieth Group. 
Cupidopsis- Group. 
Palpi beneath smoothly scaled without bristles. Frons dark with white lateral edges. Eyes bare. Veins 
8 and 9 of the forewing entirely absent , and vein 11 is separate and straight . Discal spots separate and punctiform, 
jet-black or ochreous-yellow. Hindwing beneath with three black subbasal dots (in 1 a, 7 and the cell), in 
1 c without a subbasal dot but with two separate discal dots (being a very important and certainly 
phylogenetically old mark), and with two dark but not black marginal spots which are often united into a 
transverse streak. Only the marginal spot in 2 is on both surfaces jet-black. The areas 1 c to 3 beneath and 
sometimes also above with an orange, in 1 c sometimes interrupted transverse band within the marginal 
spots. It is also remarkable that the discal spot in the area 2 of the hindwing is just as far or farther distally 
placed than the two discal spots of the area 1 c, whereas in all the species of the groups 15 to 19 it is placed 
more towards the base than the discal spot 1 c. 
Review of the Species. 
A. Hindwing without a little tail. Forewing beneath with a black dot in the discal cell behind its centre. The 
discal spot 6 of the forewing is much nearer at the base than the discal spot in 5. — N eolycaena Karsch. 
C. cissus. 
B. Hindwing at the end of vein 2 tailed. Forewing beneath normal without a black dot in the discal cell. The 
discal spot 6 of the forewing is but little nearer at the base than the discal spot in 5. —- Cupidopsis 
Karsch. C. iobates. 
C. cissus Godt. (74 g) is a species easily recognized by the marks mentioned above. E- Wings above cissus. 
dull bluish violet, forewing at the costal margin narrowly, at the apex and distal margin more broadly dark 
brown, hindwing at the costal margin as far as vein 7 and at the distal margin as far as vein 6 brown, then 
with dark marginal spots and a fine dark marginal line; marginal spot 2 with a thick yellow spot on the basal 
side, sometimes also a small yellow submarginal spot at the anal angle in 1 c and rarely also one in 3; at least 
in 1 c to 3 a fine white distal border-line of the marginal spots. The $ is above at the costal margin on both 
wings and at the apex and distal margin of the forewing very broadly blackish-brown (at the apex of the forewing 
almost to the base of area 5 and at the costal margin of the hindwing as far as vein 6); the blue colour is 
lighter, hardly violet, and it often warms distally into white particularly in the areas 2 and 3 of the forewing 
and 3 to 5 of the hindwing. Marginal spots of the hindwing like in the E, but more distinct. In the whole 
of West, South, and East Africa, to the north as far as Sierra Leone and Uganda. Madagascar. — ab. aberrans aberrans. 
Btlr. is only an aberration in which the discal spots beneath have flown together and are divided or have 
disappeared, which may occur in nearly all the species of Cupido. Madagascar.
