cliscal and hind-marginal fuscous spots are well developed. The 
under side of this $ is pale-yellowish, with the usual sjDots pronounced. 
Nothing but its large size seemed to warrant its separation from the 
variable series of Ens 
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. Fausta, Oliv., may be regarded as the 
type. 
I know of no part of South Africa where this widely-ranging 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, 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 Potchefstroom, with the note that they were taken 
on 25th February about a stony kopjo, 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. EripMa appears to be 
about the same, but I do not know of the occurrence of the latter to the north 
of Dongola.
