trace, and in one Delagoan and two Natalian specimens are totally j 
wanting. The hind-wing band is almost always bounded inferiorly by | 
the second subcostal nervule to its termination, but the terminal por- j 
tion in one Transvaal specimen projects very slightly, and in a Natalian 
individual considerably below the nervule. The under side of King's 
figure is white (as in a good many South- African examples), but the 
dark bands of the upper side are depicted as showing more plainly 
through the wings than in any specimens which have come under my 
notice. 
As regards the nervular hind-marginal spots on the upper side of 
the hind-wings, which are distinct but linear in King's figure, I find ' 
that, while it is unusual for them to occur in South-African specimens, 
they are found in those examples which more nearly approach King's type | 
(in one Delagoa Bay specimen they are rather large and conspicuous). 
On the other hand, the terminal disco-cellular spot of the fore-wings 
(which is wanting in King's type and in the more heavily-banded 
South-African examples) is most developed in specimens which bear 
the largest hind-marginal white markings on the black band. 
The ^, besides varying in ground-colour,^ exhibits great diversity 
in the development of the black band and of the apical hind-marginal * 
border of the fore-wings, and in the colouring and pattern of the apical 
patch. In one from Natal, the inner-marginal band is scarcely nar- 
rower (except for a very large white spot at the posterior angle) than 
in the more lightly marked $ s ; while the opposite extreme is met 
with in an example I captured near Grahamstown, where the band is 
exceedingly narrow, and the usual black connection with the apical 
patch is only represented by two quite separate very small blackish 
spots.2 In this example the apical patch is externally broadly tinted 
with pale dull ferruginous, and the pale enclosed spots are almost 
obsolete, and it thus on the upper side approaches the $ of Variety A., 
above described. Reiche's figure of an Abyssinian $ depicts the under 
side as inclining to argillaceous. 
In the British Museum collection I noted (October 1886) a 
remarkably large $ labelled T. opalescens, Butler, and ticketed Dela- 
goa Bay." This example is white, with the inner-marginal black of 
the fore-wings well developed, and the hind-marginal border rather 
broader than usual, — the white spots in the latter (with the exception 
of the two largest) being almost obsolete ; in the hind- wings both the

Boisduval in 1836). I have seen only three specimens, respectively from Kaffraria Proper, 
Natal, and Angola, and a coloured photograph of a fourth example which was taken by the 
late Mr. E. C. Buxton either in Natal or Swaziland. The Natal specimen, taken by Mr. 
J. M. Hutchinson in Weenen County, belongs to Var. A., having the under-side reddish 
very pronounced.

of this kind ; the description and figure show that the inner-marginal band is wholly 
wanting
