CUPID0. By Dr. C. Atjriyillius. 
B. Hindwing above before the margin with a larger reddish-yellow spot in 1 c, 2 and 3. — Forewing above 
more or less covered with lustrous coppery, reddish-yellow scales. C. mahcillakoaena. 
C. nandianus. 
C. koaena. 
messapus. C. messapus God. (73 k). Under surface grey; median spot and discal spots of forewing black and 
distinct; hindwing with black basal dots in 1 a, 7 and the cell, and black discal dots in 1 b and 7; discal spots 
1 c to 6 pale and often very indistinct; the black marginal spot in area 2 towards the base bordered with 
a small reddish-yellow spot, the other marginal spots indistinct, margined with whitish. ■— <$. Wings above 
almost to the margin dark bluish violet without median spots, but with a black marginal dot (bordered with 
yellow) in area 2. — Wings above uni-coloured brown, otherwise as in the Cape Colony, Caffraria, Abyssinia. 
sebagadis. — ab. sebagadis Guer. Hindwing beneath with a reddish-yellow spot also in area 1 c. Abyssinia. 
mahalla- C. mahallakoaena Wallengr. (73 i) is beneath marked almost exactly as messapus, but somewhat 
koaena. lighter and with a more distinct marking, distinguished by the marginal spots in 2 and 3 being both proximally 
bordered by thick orange-red bows. — $. Wings above dark violet; forewing and sometimes also hindwing 
at the base and in the centre covered with yellowish-red scales exhibiting a coppery lustre; this colouring often 
radiately extends on the veins towards the margin. — $. Wings above uni-coloured brown, only in the areas 
1 c, 2 and 3 of the hindwing with a reddish-yellow marginal spot. Owambo Land to Cape Colony and then 
trisignatus. to British East Africa. — ab. trisignatus Strd. Strand places this form to C. messapus. But if on the one hand 
the difference in the extent of the reddish-yellow colour on the hindwing above is not forcibly enough marked 
and on the other hand the lustrous coppery dusting above in the of mahallakoaena may be absent, I do not 
understand how the two species can be kept apart. Strand states the following marks of trisignatus : ,,Size 
as in messapus, 22 mm“ (I have a $ of mahallakoaena at hand with an expanse of 20 mm); ,,the upper surface 
coloured as in messapus except that the hindwing is spotted orange in 3 cells. The under surface differs from 
that of messapus in its lighter ground-colour and the presence of a similar orange marginal colouring as on 
the upper surface, which, however, owing to the lighter surroundings, does not appear so distinctly spot-shaped, 
but rather like a zigzag-like broken transverse band which also extends yet a little into the cell 4 and comprises 
a small black punctiform spot in the cell 2.“ Abyssinia. 
nandianus. C. nandianus B.-Bak. was described as a Catochrysops and is unknown to me. The description says: 
,,Both wings light violettish-blue with a narrow' black margin; forewing with traces of the lustrous coppery 
dusting by which C. mahallakoaena is so well distinguished; in nandianus, however, there are but faint traces 
of the copper colour visible and in much flown specimens even these traces disappear altogether; hindwing 
between the veins 1 a and 2 *) with a black marginal spot which is proximally bordered by a small red spot. 
Under surface similar to that of mahallakoaena, but with a very light ground-colour and somewhat larger spots 
which are more broadly edged with white. Expanse of wings: 26 mm.“ Nandi. According to the description, this 
form also seems to be a transition between messapus and mahallakoaena. 
koaena. C. koaena Strd. (74 g) was described from a single $ and, according to Strand, it is allied to C. mahalla¬ 
koaena. This affinity is exhibited by the marking beneath, but not by the marking above which is quite different 
from the $$ of the other species of this group. The description says: ,,Upper surface light blue with black 
veins and a broad black distal-marginal and costal-marginal band; in the forew'ing the former is 3 mm 
broad and everywhere equally broad . . .; the costal-marginal band is at the base narrower than the distal- 
marginal band, but towards the distal margin slightly expanded, and at the apex of the wing its width is 
about 5 mm; discocellular spot jet-black, rounded off, at least as broad (2 mm) as it is long, for the greatest 
part situate in the dark costal-marginal band.“ ,,Hindwing with a costal-marginal and distal-marginal band 
of about 3 mm width; the latter, however, is for its greater part removed by the markings enclosed therein; 
in the areas 1 b (ought to be: 1 c. Auriv.), 2 and 3 one orange crescentiform spot each which is longer than 
broad in the areas 2 and 3; in area 2 this spot encloses a jet-black circular spot.“ ,,Under surface ashy-grey.“ 
,,Forewing with black spots bordered with a pure white.“ Hindwing in the basal area with a straight transverse 
row of 3 jet-black spots in white rings, being about equally distant from one another“ . . .; ,,the marginal 
area behind vein 4 with an orange-red spot being 6 mm broad, anteriorly 3 mm long, and enclosing in area 
2 a small, jet-black eyespot which is distally and on both sides narrowly edged with blue, in the neighbouring 
areas but few blue scales are to be noticed.“ Expanse of wings: 27 to 28 mm. German East Africa: Neuwied- 
Ukerewe. It may be the $ of C. alberta Btlr. (1901)? 
Nineteenth Group. 
Chilades-gvowp. 
Eyes bare. Frons narrow, upwards somewhat tapering off. Vein 11 of forewing separate, but for 
some distance extending close along vein 12. Hindwing not tailed, beneath in area 1 c with a black basal dot and
