Annals of the Transvaal Mtjseum. 
spot between discoidal nervures is in all four 
specimens white, whereas one, a perfect specimen, 
has the apical patch a little broader, the dark 
markings very bright, and the apical spots, includ- 
ing the spot between discoidal nervures, of the 
same chartreuse-yellow ground colour. Another 
female seems to represent the extreme dry phase ; 
the general colour of both wings above is white, 
but the hind wings, owing to the dark sandy 
colour of the under side shining through, have a 
slight sandy appearance ; the dark markings are 
very much reduced in size and intensity of colour, 
the apical patch of the fore wings lighter buff 
with the spots tinted with orange, and the spot 
between discoidal nervures white. 
Aurivillius, Rhop. Aeth., p. 427, in my opinion, 
s perfectly correct in treating T. maimuma , 
Johnstoni, and opalescens as synonyms of T. eris. 
The variations in size, etc., which occur in this 
species being attributable to climatic influences, 
and in a lesser degree dependent on geographical 
distribution. It would not be surprising that in 
favourable seasons the larger form, T. opalescens 
Butl., which so far has its southern limit at 
Lourenco Marques (Delagoa Bay), will turn up, 
and perhaps even in numbers further south, and, 
in fact, some specimens in the Museum series 
from Natal and Transvaal very nearly approach 
in size T. opalescens Butl., but are in no other 
way to be distinguished from T. eris Klug. 
T. ione (Go. 14 <J(J, 5 $$. Four males are referable to the variety 
jalone Butl. ; the other ten all belong to the variety 
phlegyas Butl. The five females represent the 
typical form, with the apical patch of fore wings 
“ orange-chrome.” 
T. regina (Trim.) T... 12 3 All the males can be considered to 
be intermediate forms between the wet and dry 
phase, with the exception of one which approaches 
the typical dry phase, but for parts of some of 
the nervures of the hind wings still being black. 
The females are also intermediate forms, but show 
a greater tendency towards the dry phase than 
towards the wet phase. 
T. annae (Wallengr.).. 13 dd\ 7 $$. Ten males, more or less worn speci- 
mens, belong to the wet phase, but show already 
the influence of the dryness of the season. One 
is a distinct intermediate form, while the other
