Show 1891.] FROM SOUTH-WESTERN AFRICA. 77 parison with the much darker female of true G. natalensis, with the exception, however, of the underside markings just referred to, which are heavier in the latter than in G. amazula, Mabille. It is not improbable that the discovery of the female may render necessary the separation from O. natalensis of the differently and more brightly tinted form brought to notice by Mr. Eriksson. 26.

The specimens of this striking Crenis are considerably larger than Dewitz's figure of a male from Chinchoxo, expanding 2 in. 5% to 7 lin.; and the black markings of the upperside are better developed, especially the apical hind-marginal border of the fore wings, which emits rather long nervular rays, and the discal spots of the hind wings, which are four or five in number, instead of two only. In all the specimens (except one from Ehanda) there also appears on the upperside of the fore wings a submarginal series of very small indistinct internervular black spots, corresponding to the series of larger ones on the underside. 27.

I have noticed these specimens in the third volume of m y ' South- African Butterflies' above quoted, and pointed out the characters distinguishing the male from the female type of the species. Unlike its near congener, C. benguelce, this most beautiful Crenis is recorded from a very wide range in Africa, including Lake Nyanza and Delagoa Bay. In the male the tint of the upperside varies, some specimens being bluer and others pinker in tinge, and the black markings vary a little in size and distinctness. On the underside there is considerable variation in the width of all the shining greenish-white markings of the hind wings. 28. CRENIS CONCORDIA (Hopff.). 5. Harma concordia, Hopff. Monatsb. k. Akad.

It is remarkable to find this apparently very rare species, founded on a single female specimen from Querimba, occurring some 4° further S. on the opposite side of the continent. |
