CUPID0. By Dr. C. Aurivillius. 
above is broad and unspotted, the transverse streak at the end of the discal cell, however, is very short and 
does not reach to the posterior angle of the cell, and the base is as far as vein 2 at most black. Hindwing 
above white, at the base narrow black (only as far as vein 2) and with a narrow black marginal band in 
which two fine white lines border on the longisli black marginal spots. The under surface is described in the 
review; we may merely add that the black basal streak of the forewing is much shorter than in the other species. 
It occurs in the mountainous districts of East Africa from the Kilima Ndjaro to Mt. Elgon. 
Sixth Group. 
The only species belonging hereto is closely allied to the preceding group and is regarded as a Castalius 
by Fruhstorfer. But as the eyes are hairy and the hindwing tailless, and besides the CS exhibit androconia, 
I think it better to keep up a separate group for C. isis. Vein 11 of the forewing is for a long distance entirely 
fused with vein 12. 
The marking beneath also differs rather considerably from that of the forms of Castalius by the subbasal 
spot 1 b of the forewing being absent or appearing only like a shade, and by the hindwing showing be¬ 
hind the middle a broad, coherent submarginal band which must have been created either by the junction 
of the discal and submarginal spots or by the expansion of the latter. In the latter case the hindwing is entirely 
without the discal spots. 
isis. C. isis Drury (73 b, c). <§. Wings above bright light blue; forewing in the centre with a white spot 
covering the bases of the areas 2 to 4; hindwing above with a white discal band of about 4 mm width, reaching 
to the costal margin and to the proximal margin and being narrowed near the costal margin by a dark spot 
in the basal part of area 6. In the $ the wings above are black and white, at the base with a faint bluish reflection; 
the white discal band of the hindwing is like in the C; the white spot of the forewing, however, is strongly 
expanded and reaches to the posterior margin; in addition there is a white subapical spot in 4 and 5, being 
absent in the C- Sierra Leone to Angola, Uganda and Equatoria. 
Seventh Group. 
An easily recognizable group. Eyes densely haired. Hindwing without a small tail and above without 
a white discal band. Vein 11 of the forewing is for some distance fused with vein 12. The basal streak of the 
forewing beneath is long and broad, usually reaching to the apex of the discal cell, but only at the base purely 
black, then lighter or darker brown; a transverse streak at the end of the discal cell; the discal spots 3 to 6 
(and 9) form an almost straight transverse band; whilst the discal spot 2 is situate more towards the base. 
The submarginal spots are narrow, strigiform, and generally form a coherent submarginal line. The marginal 
spots are rounded, separate and sometimes partly indistinct. On the hindwing beneath the basal dots generally 
form a short streak following the posterior side of vein 8; a transverse streak at the end of the discal cell; the 
discal spots are sometimes rounded and black, sometimes partly strigiform and lighter or entirely absent. 
Submarginal and marginal spots like on the forewing. 
How very uncertainly the modern so-called genera in which the species of Cupido have been distributed 
are defined, is exhibited also by the fact that many authors have placed C. eleusis Dem. into the same genus as 
jesous, denominating the genus sometimes Lampides and sometimes Azanus. It is not mentioned, however, by 
which marks this ,,genus“ is distinguished from the others. C. eleusis has bare eyes, vein 11 of the forewing 
quite separate, and the hindwing tailed, and it also differs in the marking very much from the species of the 
present goup. 
Review of the Species. 
A. Forewing beneath with a dark dot in the discal cell opposite the base of area 2. The discal spot 9 of the 
forewing beneath is, in case it be present, situate right in front of the discal spot 6. The marginal spots 
1 c and 2 on the hindwing beneath are strewn with blue scales. Fringes of the wings whitish-grey or grey, 
often distinctly spotted. 
a. The discal spot 3 of the hindwing is larger than the discal spots 4 and 5 which are sometimes entirely 
absent, and it is situate close at the submarginal line. The discal spot 4 of the forewing is at vein 4 distally 
more or less extended. The marginal spot 2 of the hindwing beneath is never proximally bordered with 
yellow or red. C. natalensis. 
p. The discal spot 3 of the hindwing forms a straight transverse line with the discal spots 4 and 5 and is 
always smaller than the discal spot 4. The discal spot 4 of the forewing is distally straiglitly cut oft or 
rounded. 
*. The marginal spot 2 of the hindwing beneath is not proximally bordered with yellow or red. — <$. 
Wings above with a dark marginal band of about 1 mm width. — $. Wings above brown, in the 
centre not or indistinctly lighter. C. moriyua.
