orange better defined inwardly (and sometimes faintly blackish edged), 
while its outer blackish border is broader, and forms a broad mark 
immediately above posterior angle, which is quite wanting in Evarne ; 
and, on the under side, sulphur-yellow and deep-yellow take the place 
of the white area of fore-wing and the yellowish- white of the hind- 
wing. I have not seen a ^ Evarne^ but, judging from King's figures, 
it has much smaller black markings than the ^ Aiixo, and wants the 
whole of the discal spots of the hind-wings except the costal one 
(which is exceedingly small), while the pale-yellowish under side has 
the markings very faint and reduced throughout/ 
Colonel Bowker forwarded in 1873 the paired sexes, taken at 
Fort Warden on the Kei River : the $ of this pair was almost white, 
with the apical colouring pale salmon-reddish, and the black markings 
moderately developed. From Kaffraria Proper he had previously sent 
a good series of both sexes, quite agreeing with the Natalian typical 
form ; and among the few more recently sent by him from Natal is 
a fine example of the dimorphic $ wanting the orange at the apex of 
the fore-wings. During my stay in Natal I noticed but few of this 
gaily tinted species ; those that I captured flew with moderate activity, 
and settled often on flowers. These individuals were taken in February 
and March. ^ Westward of the Kei River, Auxo appears to be scarce, 
being mostly replaced by Topha, Wallengr. ; but Mr. J. P. Mansel 
Weale has recorded (Trans. Ent. Soc. Lond.., 1877, p. 274) the 
occurrence of a number of specimens in a spot near King William's 
Town which had, during the preceding summer, yielded only To'plia. Mr. 
Weale notes the appearance of the species from December to April. 
The Variety A. above described seems to be numerous in the 
interior on both sides of the tropical boundary, specimens having been 
sent from those tracts by Mr. Selous, Mr. Eriksson, and Mr. Fry.

^ Another even nearer ally of Auxo occurs on the White Nile and in Abyssinia, viz., 
Xanthevarrie, Butl. {loc. cit., n. 123). The S has a larger orange patch, without any trace 
of inner dark edging, and the ? has very strong black markings ; while the apex of the fore- 
wings is in both sexes much rounder. 7\ citreus, Butl. {loc. cit, n. 120), from the White Nile 
and Hor Tamanib— I have received from Professor Meldola a pair from the latter locality — 
is a smaller form, with the under side in both sexes (but more strongly in the 9 ) pale reddish- 
creamy reticulated with grey hatchings. The Evarne of Geyer {Forts. Iliihn. Zutr. Exot. 
Schmett., ff. 993-994), from Senegal, is evidently a variety of the 9 of this form, in which 
the apical orange is wanting. In the ? I have from Hor Tamanib there is scarcely the 
faintest tinge of that colour. 
^ Mr. A. D, Millar notes the abundance of the species in certain localities near D'Urban 
during December 1887. It frequents the same species of creeper that is affected by T. 
Annce. Three 6 s and two ? s were kindly forwarded by Mr. Millar.
