C. grammicus Gr. Smith. (= louisae Ern. Sh.) (74 f) deviates from all the other species of this group 
by the wings being blackish also in the above, without any blue. Frons black with white lateral margins. 
Forewing above uni-coloured black (<J) or like the hindwing above with rounded marginal spots on both sides 
bordered with white. Finder surface white with black markings; forewing with a long and broad basal streak 
as far as the centre of the costal margin, a posteriorly expanded transverse spot formed by the united subbasal 
spots of the areas 1 b, 2 and the discal cell, a transverse spot at the end of the discal cell, a coherent transverse 
band from the posterior margin towards the apex of the wing, formed by the discal spots 1 b to 5, a large and 
long discal spot near the base of area 6, uniting with the transverse streak at the cell-end, and with the 
usual submarginal and marginal spots, of which the former are more or less united, the latter quite separate. 
The discal spots of the hindwing beneath are in pairs united with each other into transverse streaks, so that 
the spots 1 c and 2 form a transverse streak, 3 and 4 another one, and 6 and 7 a third touching the apex of 
the discal cell; the discal spot 5 is situate more towards the margin than the others, but generally it is 
coherent with the discal spot 4; the submarginal spots are all separated, but far remote from the margin and 
often touch the discal spots 1 c to 5; marginal spots rounded, quite separate, in the areas 1 c to 5 decorated with 
green scales. This small species is apparently rare and was hitherto only found in German and British East 
Africa as well as in the Somali Land. It was at first described by Grose-Smith as a Lycaenesthes. 
C. quadratus Grant is smaller (expanse of wings: 16 to 19 mm) than the following species and, according 
to Rebel and Bethune-Baker, it also differs from it by the formation of the male genital organ. In the 
colouring and marking, however, it agrees very closely with theophrastus. Island of Sokotra. 
C. theophrastus F. (Vol. I, t. 77 i) has been described and figured in Vol. I. As all the specimens from 
the Ethiopian region, which I have seen, belong to the following species, it is uncertain whether theophrastus 
occurs there. 
C. mediterraneae B.-Baker (7^ a) is very closely allied to theophrastus and was recently (1917) separated 
as a distinct species by Bethune-Baker in his ,,Revision of the Forms of Tarucus' 1 ". It differs from theophrastus 
in the marking only by the submarginal spots of both wings being streak-shaped and united into a coherent 
line; sometimes all the spots of the hindwing beneath (except the rounded marginal spots) are light brownish 
or yellowish instead of black; such specimens are on an average smaller and probably represent the dry season 
form; the marginal spots 1 c to 5 of the hindwing beneath are decorated with green or silvery scales. According 
to Bethune-Baker, the species also differs rather much from theophrastus by the formation of the male genital 
organ and is therefore even placed by him to another division of Tarucus. Both the species fly together in 
Algeria. Although it is of course possible, it must still be regarded as a doubtful question whether there are 
really species solely discernible by the structure of the male genital organ and having quite similar, not deviating 
females. This question of the variability or eventual dimorphism of the male genital organ can only be solved 
by the examination of this organ in a great number of EG originating from the same couple. — The species 
is before me from Nubia, Khartum, Cordofan, and the Vere Mountains in Adamaua. 
C. hintza Trim. (73 b) forms a distinct transition between the preceding species ( Tarucus) and the 
following ( Castalius ), the discal spots being situate like in the former, the submarginal spots like in the latter. 
S- Wings above of a delicate violettish-blue, the markings beneath more or less diaphanous; with small, longish, 
separate, dark marginal spots, which are larger and black only in 1 c and 2 of the hindwing. The under surface 
with the normal black markings and nearly all the spots separate, the discal spots 2 to 4 and 6 of the hind¬ 
wing are rounded and situate near the base of their area; the discal spot 5 of both wings and the discal 
spot 3 of the forewing, however, are situate far towards the margin close at the submarginal spots; submarginal 
spots of both wings separate, streak-shaped; marginal spots small and separate, only in the areas 1 c and 2 
larger and scaled green; frons white with two short black lines of bristles. The $ is beneath similar to the U, 
above blackish, in the centre white with black veins and discal spots, whereby the white colour is divided into 
several angular spots; both wings at the base almost to the apex of the discal cell covered with bluish. Cape 
Colony to Nyassa Land and Rhodesia. —• resplendens Butl. from Abyssinia is unknown to me and described 
according to a $; the description does not state any other differences from hintza -§ but the dark submarginal 
band on the forewing above not being entirely connected with the marginal band. 
The following species of this group are easily recognizable by the wings above being in both sexes black and white, 
without a blue reflection. The white colour forms on the forewing a large anal-marginal or median spot reaching at least to 
vein 6, and besides also generally 1 to 3 white spots in the dark marginal band. The white median spot also invariably 
forms a small or larger spot in the discal cell. The hindwing shows a white median band invariably reaching to the proximal 
margin, often also to the costal margin. The discal spot 5 of the forewing is large, extended towards the margin, but united 
with the others.
