78 SOUTH-AFKICAX EUTTEEFLIES. 



broivn. Umdek side. — Fore-wing : blackish markings not clouded with 

 white ; white markings generally more or less tinged with sulphur- 

 yellow. Hind-ioing : all the white markings usually more or less 

 tinged with sulphur-yellow along margins of wing. 



As above noted, the size of this species is very variable. I have 

 observed that, although large examples are found throughout the 

 South-African range, all the smallest specimens come from the drier 

 (usually upland and interior) tracts. 



Variety A. — $ and $ {Melanarge, Butl.). 



^ Ground-colour decidedly creamy; along hind-margins a dull 

 ochrey-reddish tinge tinging both black border (especially about apex 

 of fore-wing) and outer part of its creamy spots. Ukder side. — 

 Hind-iving and apical hind-marginal area of fore-wing suffused ivith 

 dull ochrey-reddish (in the imler portions with a tinge of pink) dusted 

 toith dark-grey ; the dark bands and border very ill-defined reddish- 

 brown, in some specimens scarcely distinguishable. 



$ (Two examples). Ground-colour pale sulphur-yellow. Under 

 SIDE. — As in ^, but the ochi-ey tint paler, not so red, and with the 

 position of the typical white markings vaguely indicated by some 

 whitish clouding. Forc-wivg : pale markings sulphur-yellow. 



{Hah. — Natal, Delagoa Bay, Transvaal, Griqualand West, Damara- 

 land, and Somaliland.) 



From Mr. Butler's description (loc. cit.) I think that there can be 

 no doubt that his Melanarge, of which he describes three male examples 

 from Somaliland, is identical with the Variety A. just described.'^ I 

 should also refer to the same variety his Lacteipennis {Ann. and Mag. 

 Nat. Hist., 4th Ser., xviii. p. 489, 1876), from Abyssinia, notwith- 

 standing its unusually small size {exp. cd. i in. 7 lin.), if it were not 

 for his description of the hind-wings as having " several submarginal 

 black spots, sagittate (with the j^oints upwards), towards apex," which 

 looks as if the ordinary white-spotted black border of the upper side 

 were wanting on those wings. 



I have not been able to discover any character by which Tritogcnia, 

 Klug, can be separated from Eripliia, Godt. The description of the 

 latter only differs in giving four instead of six white spots in the black 

 border of the hind-wing ; but these spots vary a good deal in size and 

 distinctness, and Godart probably did not include the first large costal 

 spot (which, indeed, is but narrowly separated from the central 

 white field) ; and I have seen several examples in which the sixth 

 (last) spot is almost obsolete. Mr. Butler, in the paper last cited, 

 observes: " Eripliia, which I have examined from Angola, is a larger 

 and more creamy-coloured insect than H. Tritogenia (with which it 

 has been united), . . . the markings are not quite the same on 



^ Under the name of Jlcrpccnia iterata, Mr. Butler has recorded some examples from 

 Kilima-Njaro [F. J. Jackson\ stated to differ from II. melanarge only in its considerably 

 larger size (55 mm. = about 2 in. 2 lin.), and in the broader subbasal black belt and larger 

 white marginal spots in the hind-wings {/Voc. Zool. Soc. Lond., iSSS, p. 96).
