122 SOUTH- AFRICAN BUTTERFLIES. 



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 Ecarne ; 

 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 ^ Uvarnc, but, j udging from Klug's figures, 

 it has much smaller black markings than the $ A^ixo, 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 Eiver : 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 $ wantiug the orange at the apex of 

 the fore-wings. During my stay ia 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 Tojoha, 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 TojjJia. 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., 

 Xanthevarne, Butl. (he. 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. T. 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 Evarnc of Geyer [Forts. Hilbn. Zutr. Exot. 

 Schmdt., ff. 993-994), from Senegal, is evidently a variety of the 9 of this form, in which 

 the apical orange is wanting. In the 9 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 18S7. It frequents the same species of creeper that is afifected by T. 

 Annie. Three 6 s and two 9 s were kindly forwarded by Mr. Millar.
