LYCAENESTHES. By Dr. C. Aubivillius. 
) o ’> usta. 
L. robusta Auriv. (71b). Wings above blackish with a distinctly defined blue area; the blue 
area of the forewing is situate at the base, covering the areas 1 a and 1 b as far as beyond the middle (the 
black part of 1 b about 4 mm broad), almost the whole discal cell and the basal quarter of area 2; on the hind¬ 
wing the blue colour covers the discal cell, the anterior longitudinal half of 1 c, the areas 2 and 3 almost to 
the margin and the areas 4 and 5 as far as 2 mm before the margin. Wings beneath whitish with discal spots 
bordered with brown and a similar transverse spot at the end of the discal cell. Forewing besides with a brown¬ 
ish, white-ringed spot in the discal cell (this spot is absent in all the other species placed to Cupidesthes 
by Bethune-Bakek), and the hindwing with four such basal spots. Hindwing in the anal region with four 
black dots scaled silvery white at the margin, one in 1 b, two in 1 c, and one in 2. unknown. Cameroon. 
Second Group of Species. 
The species of this group are very numerous, but all are immediately recognizable by the forewing 
beneath being uni-coloured as far as the apex of the discal cell without any markings or only with one 
black longitudinal streak at the base of area 1 b. 
Both wings beneath have a transverse spot at the end of the discal cell and a more or less irregular 
row of discal spots. These spots are generally in the middle not darker than the ground-colour, but on 
each side bordered at first by a dark and then by a white or whitish transverse streak or transverse bow. 
On the forewing follows then a transverse row of 6 or 7 submarginal spots bordered with white, and a dark 
marginal line being often proximally bordered with white. Hindwing beneath usually with 1 to 4 basal dots, 
two white submarginal lines composed of bows, and a white and a dark marginal line; in addition generally 
black, metallic scaled eye-spots proximally bordered with yellow or red in 1 b, 1 c, and 2. 
Review of the Males. 
I. Forewing beneath in the basal part of area 1 b not coloured black. Frons with bristly hair, black, with 
fine white lateral lines, rarely also lighter whitish-grey along the middle. Hindwing with 3 to 5 hair-tufts 
at the ends of the veins 1 b, 2 and 3 (4 and 5). 
A. Hindwing beneath without any basal dots or basal spots and thus as far as the apex of the discal 
cell uni-coloured without markings. 
a. Both wings above monotonously dark bluish-violet without markings. 
*. All the discal spots of the hindwing of the ground-colour (not red). L. musagetes. 
**. At least the discal spot in area 1 b of the hindwing filled up with red. 
1. The discal spot in 7 of the hindwing is red and punetiform. L. anademci. 
2. All the discal spots of the hindwing filled up with reddish. L. ituria. 
(3. Wings above dark brown without a violet tinge; hindwing above with a broad orange marginal band 
and black marginal dots in 1 b to 5. L. rvhricincta. 
B. Hindwing beneath at least in area 7 with a basal dot or basal spot. 
a. The basal spot in area 7 of the hindwing is not distinctly prominent and never black with a light 
ring; it is not darker than the ground-colour or at least not darker than the discal spots. 
*. Forewing above black with a distinct light blue anal-marginal spot reaching the base of 
the areas 1 a and 1 b. Frons black with fine white lateral lines but without a light median line. 
Hindwing beneath without a spot in the discal cell; above almost entirely blue or light greenish 
(Bethune-Bakek places these species to Cupidesthes). 
o. <$. The bluish-greenish anal-marginal spot of the forewing above does not cover the discal 
cell but only the base of the areas 1 a and 1 b. The dark transverse line proximally bordering 
in the forewing beneath on the discal spot in lb, is removed far towards the base and almost 
reaches the base of vein 2. — $ with anal wool. Both wings above in the centre or for 
the greatest part white. 
1. <$. Anal-marginal spot of forewing and hindwing above as far as the proximal margin 
violettish-blue. L. voltae. 
2. Anal-marginal spot of forewing light silvery blue or greenish; hindwing above at 
the costal margin black, at the proximal margin broadly whitish, otherwise light silvery 
blue or greenish. L. arescopa. 
§§. <$. The blue anal-marginal spot of the forewing covers the discal cell and almost reaches 
the margin in 1 a (and lb). — $ without anal wool. Both wings above dark greyish-brown, 
in the middle not or only faintly lighter.
