PIERINii:. 119 



discal series usually smaller and narrower ; spots of hind-marginal series 

 usually small, diffused and separate, but occasionally so much enlarged 

 as almost to touch each other. Undku SIDE.— As in ^, but spots of 

 discal series in both wings, and terminal disco-cellular spot on hind- 

 wing, larger, and more distinctly silvery-centred. Forc-iving : reddish 

 streaks on inner side of apical patch enlarged and confluent ; a hind- 

 marginal series of minute nervular black spots. 



Wallcngrenii appears to represent in the south tho species named 

 Eiqjom'pc by Klug {Symh. Phys., pi. vi. If. i 1-14), which that author 

 records from Abyssinia, Dongola, and Arabia, and which Geyer {Zutr. 

 Ex. Schmctt. Iliihn., ff. 991-992) also figures from Senegal. In the 

 typical Eupompc, the carmine red of tho apical patch is in both sexes 

 more vivid and pure than in Wallcngrenii, and the under side of the 

 hind-wings is white, and either without or with quite minute discal 

 spots. The $ is represented by Klug as having the basal grey broadly 

 and strongly developed, as well as the large nervular spots of the hind- 

 wings; but the discal series of the latter wings are faint ochreous- 

 yellow, while on the under side the wide subapical red of the fore-wing 

 and the discal spots of the hind-wing (orange-yellow with imperfect 

 thin blackish rings) are marked features. I possess, however (through 

 the kindness of Professor Meldola), specimens from Harkeko, on the 

 Red Sea, collected by Mr. J. K. Lord, which, in the decidedly yellowish 

 under side of the hind-wing in both sexes, exhibit a tendency in the 

 direction of Wallcngrenii ; the two $ s of this variation are much 

 smaller and with much less developed basal clouding than King's 

 figure, and one $ entirely wants the apical red in the fore-wings. 



As shown by the measurements given above, Wallengrenii is extremely 

 variable in size. Judging from coloured photographs sent to me by the late 

 Mr. E. C. Buxton, some of the specimens taken in Swaziland are even smaller 

 than the minimum I have given. On the otlier hand, a S from Delagoa Bay 

 surpasses the maximum I have given, expanding as widely as the largest $ 

 Annce. Nevertheless, the characters empliasised in my description of Wallen- 

 grenii suffice to distinguish the butterfly even from the Variety A. of AnncB, 

 which most nearly approaches it.
