CUPIDO. By Dr. C. Aurivillius. 
o. Hindwing tailless. Vein 11 of forewing for some distance united with vein 12. 
1. Hindwing above with a purely white, coherent, broad median band. Sixth Group. 
2. Hind wing above without a white transverse band. — Azanus Moore. Seventh Group. 
oo. Hindwing at vein 2 tailed. Vein 11 of forewing quite separate. — Syntarucus Butl. 
Eighth Group. 
B. Forewing beneath at the base always without a dark longitudinal ray and without markings at the 
costal margin in area 12 *), generally unmarked as far as the apex of the discal cell. 
a. Both wings beneath at the end of the discal cell with a transverse streak or transverse spot. 
*. Both wings beneath without any black punctiform spots at the base. 
o. Hindwing beneath with two jet-black marginal spots at most in 1 c and 2. Eyes hairy. The 
discal cell of the fore wing beneath opposite vein 2 with a large spot often only marked by 
its white border-lines. 
1. Vein 11 of forewing for a long distance united with vein 12. — Nacaduba Moore. — Hind¬ 
wing in the African species tailless. Ninth Group. 
2. Vein 11 of forewing separate. 
a. Hindwing at the end of vein 2 tailed. The marginal spot in area 2 of the hindwing 
beneath towards the base bordered with yellow. — Lampides Hubn. 
Tenth Group. 
b. Hindwing tailless; its marginal spots not proximally bordered with yellow and some¬ 
times absent. — Cyclyrius Butl. Eleventh Group. 
oo. Hindwing beneath at least with four large, jet-black marginal spots dusted with a metallic 
colour (in the areas 2 to 5). Eyes bare. — Brephidium (Scudd.) B.-Baker. Twelfth Group. 
**. At least the hindwing beneath at the base or at the costal margin with 1 to 4 sharply prominent 
black dots generally surrounded with white. 
x. Hindwing beneath in the areas 3 to 6 without marginal spots or only with indistinct light 
(yellowish) spots. Ground-colour of the under surface more or less covered with yellowish. 
Discal spots of both wings black and separate or almost separate. Wings on both surfaces 
with sharply defined black marginal line and fringes. — Neochrysops B-Baker (ex parte) 
Fourteenth Group. 
x x. Hindwing beneath in the areas 3 to 6 with distinct dark (grey, brown or black) marginal 
spots surrounded with light (whitish). These spots are rarely indistinct, but always dark. 
Ground-colour of under surface never yellowish. 
o. Vein 11 of forewing quite separate and straight. 
f. The discal spots 1 c to 6 of the hindwing beneath are lighter than the subbasal 
dots or at least lighter than the subbasal dot 7; rarely almost black, scarcely lighter 
than the subbasal dots, but in this case at least in the areas 4 and 5 large, angular 
and contiguous. They are generally slightly darker than the ground-colour and 
only owing to their thick whitish bordering distinctly prominent. 
1. The discal spots are never white-pupilled. All the subbasal spots of the hindwing 
with a black pupil. The marginal spot 2 of the hindwing beneath proximally 
bordered with orange-yellow or sometimes without a special border. -— - Eudiry- 
■sops Butl. and N eochrysops B.-Baker (ex parte). Fifteenth Group. 
2. Hindwing with 4 subbasal spots (in 1 a, 1 c, 7, and the cell), but only the subbasal 
spot in 7 with a black pupil. The marginal spot 2 of the hindwing beneath proxi¬ 
mally bordered with hemochrome. Eyes hairy. Hindwing tailed. 
Seventeenth Group. 
ff. The discal spots 1 c to 6 of the hindwing beneath not or scarcely lighter than the 
subbasal dots with or without a light ring, often separate and punctiform, never 
large and transverse. Sixteenth Group. 
oo. Vein 11 of forewing always bent towards vein 12, often touching it or united with it. 
f. The discal spots 1 c to 6 of the hindwing beneath neither black nor punctiform. 
Eyes bare. 
*) In the species of the ninth group ( Nacaduba ), however, there sometimes occur fine, white (indistinct) transverse 
streaks in area 12.
