C. poggei Detv. (72 k), owing to the separate velvety stripes on the forewing above, is generally placed 
next to C. falkensteini, but by the marking beneath it approaches more the preceding species. It occurs in Angola, 
Rhodesia, Manica Land, Nyassa Land, and British East Africa. — As poggei ? (72 i) a species is figured, being 
entirely unknown to me or wrongly marked. 
C. nubifer Trim. (= pelotus Karsch) (72 i) is above very similar to C. cordatus except the two 
marginal spots of the hindwing being small and showing no metallic scales, but beneath it differs by the marks 
stated in the review, and on the hindwing beneath it has large, blackish-grey, oblong-quadrangular cliscal spots 
bordered with black and connected with each other into a transverse band; the space between the submarginal 
lines of the hindwing is entirely or for the greatest part filled up with a dark leaden grey colour. The $ above 
is without the velvety spot, but with black cliscal spots and a black spot at the cell-end. Natal to British East 
Africa; also found by Dr. A. Schttltze in Cameroon near Bamenda. —- ab. distinctesignatus Strand (72 k as 
distinctissima) differs by the white markings beneath on both wings being more distinctly prominent. Abyssinia; 
similar specimens, however, are also before me from Kilima Ndjaro and Ruwenzori. 
C. delatorum Heron entirely agrees in the marking with the following species, but it deviates by a 
different shape of the wings corresponding with that of nubifer (72 i). This difference may be expressed in such 
a way that if two equally large and similarly spanned specimens are compared with each other, the distance 
between the apex of the forewing and the anal angle of the hindwing is larger in delatorum than in falkensteini. 
There are, however, specimens before me from Ruwenzori forming the intermediary of the two forms, and 
I therefore take it to be probable that delatorum is only a race of falkensteini. Ruwenzori, Elgon, and from the 
mountains bordering on the north-west of Lake Tanganyika. 
C. falkensteini Detv. (73 a) differs from all the other species of the genus, except delatorum, by the 
fine black velvety lines on the forewing above. The $ which is not before me has a whitish ground-colour 
above with a broad black marginal band of both wings, a dark costal margin of the forewing and black cliscal 
spots. The typical form occurs from Sierra Leone to Angola and British East Africa. —- artemenes Mab. (72 k) 
is the form occurring in Maclagaskar, apparently only distinguished by the purely white ground-colour of the 
fore wing beneath. 
Third Group. 
This group was established in 1909 by F. A. Heron as a separate genus, Harpendyreus, for a new species 
from Ruwenzori. It is in fact an intermediary between the second and fourth groups and shows how closely 
these two are connected. 
The forewing has only 11 veins, and vein 11 is quite separate without being fused with vein 12. Hind¬ 
wing at the end of vein 2 feebly angular without any small tail. It is not mentioned whether the eyes are bare 
or hairy. They are probably hairy, in which case Harpendyreus can only be distinguished from the species 
of the second and fourth groups by the absence of the small tail on the hindwing. But as the small tail of the 
hindwing is of such little systematical importance in the genus Cupido that it may be absent or present in races 
of the same species, it is evident that the genus Harpendyreus can be but faintly supported. 
In the marking beneath the only species known closely approximates the species of the second group, 
particularly C. antinorii Oberth., but it differs by the discal spot 2 of the forewing being situate almost right 
behind the discal spot 3 and not much more towards the base. 
C. reginaldi Heron is not before me, but according to Heron’s description and figure it has the size 
and shape of the wings of C. falkensteini (73 a). <$. Wings above dull violettish-blue with a broad, blackish 
marginal band and feebly transparent markings beneath; fringes white with dark spots on the ends of the veins; 
hindwing at the margin in area 2 with a small, rounded, black, blue-scaled spot proximally defined by yellowish, 
but without such a spot in 1 c. Beneath the hindwing and apical half of the forewing shows a whitish-grey 
ground-colour, whilst the basal half of the forewing is brown; the discal spots of the forewing are ring-shaped 
and form a feebly bent, coherent transverse band from the costal margin to the proximal margin; the proximal 
submarginal line is undulate and coherent, the distal line consists of separate dark dots, one in each area; the 
spots beneath are almost entirely arranged as in C. antinorii, but darker and more compressed. The $ is on 
both sides much darker than the <$ and above scarcely lined with blue. Ruwenzori. 
Fourth Group. 
This group having been denominated by Butler Cacyreus, though it was never characterized by him, 
is so closely allied to the preceding groups that it might better be united with them. I formerly believed that 
the two groups could be distinguished by vein 11 of the forewing being for some distance fused with vein 12 
in the species of the second group, whilst in Cacyreus it runs separately. On examining it more closely, however,
