PIERINyE. 
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. Under 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-iuinrj : reddish 
streaks on inner side of apical patch enlarged and confluent ; a hind- 
marginal series of minute nervular black spots. 
Wallcngrcnii appears to represeut in the south the species named 
Eupompc by Klag {Symt. Fhys., pi. vi. ff. I I — 14), which that author 
records from Abyssinia, Dongola, and Arabia, and which Geyer (Zutr. 
Ex. ScJmctt. Ililhn., ff. 991—992) also figures from Senegal. In the 
typical Eupompe, the carmine red of the apical patch is in both sexes 
more vivid and pure than in Wallcngrcnii, 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 
Ked 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 Wallcngrcnii ; 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 ^ from Delagoa Bay 
surpasses the maximum I have given, expanding as widely as the largest ^ 
Annce. iievertheless, the characters emphasised in my description of Wallen- 
grenii suffice to distinguish the butterfly even from the Variety A. of A7i7ice, 
which most nearly approaches it.
