64 RHOPALOCERA AFRICA AUSTRALIS, 



apex larger than in $ . Hind-wing : more thickly flecked 

 than in $ , the spots and atoms pinker ; the largest spot on 

 costa silvery-centred, and the first of an irrregularly inter- 

 rupted row of from four to six similar spots, of which the 

 two central spots are the largest, parallel to, and not far from, 

 hind-margin. The under-side is much subject to variation. 



M. Boisduval, in his Appendix to M. Delegorgue's Travels, considers 

 this species as the type of a new Genus (Dryas) ; but Mr. Doubleday, in 

 his notice of the Genus Eronia in the " Genera of Diurnal Lepidoptera," 

 states that he can discover no structural distinctions to warrant the separa- 

 tion of Leda from the last named Genus. Boisduval considers Dryas as a 

 Genus intermediate between AntJwcharis and Eronia. If the bright-orange 

 colouring at the apex of the fore-wings can be considered as indicating a 

 generic affinity to Anthocharis no doubt M. Boisduval is right ; but this 

 appears to me to be the only mark of resemblance to the insects of the 

 latter Genus to be found in this lovely Butterfly. M. Boisduval further 

 remarks that specimens from Abyssinia are a third less in size than those 

 lie received from Natal. The insect is one of the most striking of the 

 South African Butterflies, and must be conspicuous on the wing.

? . White ; with broad black hind-margins, fore-wing : 

 hind-marginal band widest at apex (where, near costa, are 

 one or two rounded white spots), its inner edge slightly 

 crenelated, and with a conspicuous, broad projection imme- 

 diately above first median nervule. Hind-wing : hind-mar- 

 ginal black band broad, spotless, irregularly dentate on its 

 inner edge, with a large, conspicuous, irregularly-shaped 

 projection, more pointed than that of fore-wing, on second 

 subcostal and discoidal nervules (this projection is occasion- 

 ally separate from the black band, forming a distinct spot). 

 UNDER-SIDE. Fore-wing : hind-marginal band blackish, but 

 margined outwardly by a ferruginous, grey-dusted stripe, 

 wide at apex (where it encloses a conspicuous creamy -yellow 

 marking, which has a downward projection), narrowing to, 

 and ending at, extremity of third median nervule. Hind- 

 wing: soft creamy-yellow ; hind-marginal band ferruginous, 

 varied with silvery-grey, the inner projection continued to 

 extremity of discoidaf cell ; also the following spots of the 

 same mingled grey and ferruginous : an elongate mark on
