PIERIN.E. 97 



cliscal and liind-margiual fuscous spots are well developed. Tbo 

 under side of tliis $ is pale-yellowish, with the usual spots pronounced. 

 Nothing but its large size seemed to warrant its separation from the 

 variable series of Eris $. 



The $ of this species presents a very striking and peculiar appear- 

 ance, owing to the intense highly-glossy black (and great width exte- 

 riorly) of the inner-marginal band of the fore-wings, and also to the 

 unusual colouring of the apical patch, which combines to a considerable 

 extent the characters of the same marking in T. Subfasciatus and T. 

 lone, Godt. The $ also has an aspect unlike that of the same sex of 

 any of its congeners, but shows some approach both to lone and to 

 the desert group of which T. Fauda, Oliv., may be regarded as the 

 type. 



I know of no part of Soutli Africa Avhere this widftly-rangiiig African 

 species is at all numerous. I saw a few examples in the '• Thorn " country 

 near Greytown, in Natal ; they were $ s, and flew with great rapidity. This 

 was in March 1867, and the only other opportunity I had of seeing the butter- 

 fly in life was in January and February 1870, in the Albany district of the 

 Cape Colony, where I captured one of each sex. Mr. W. Morant sent me 

 some specimens from near Potchefstrooni, with the note that they were taken 

 on 25th February about a stony kopje, and flew very strongly. Mr. D'Urban 

 found the species near King William's Town in March and April. 



Like T. Subfasciatus, this butterfly seems to be more numerous in the 

 Tropical parts of Africa, but it has also an immensely wider distribution 

 northwards, having been recorded even from Cairo. There were fifteen speci- 

 mens in the small collection made in Damaraland by Mr. J. A. Bell. As 

 Gerstacker remarks, the range of this species and of H. Eriplda appears to be 

 about the same, but I do not know of the occurrence of the latter to the north 

 of Dongola.
