first and second median branches terminating in black spots and 
the spots on the dise much larger; the secondaries show a broad 
bright saffron-yellow costal streak and a paler longitudinal sub- 
median streak, and the nervures are tipped with black.

The female now received is smaller than the type from Delagoa 
Bay, and has a broader black internal border to the primaries (in 
which respect it more nearly corresponds with the male); but of 
a pair received from the Victoria Nyanza, this border in the female 
corresponds with that of the type. As more examples of these 
representatives of 7’. e7’s come to hand, the fact that they are true 
to locality seems to be gradually established on a firmer basis.

3. Nearly resembles 7. vesta on the upper surface, but the base 
of the wings is dusted with bluish grey instead of black, the outer 
area creamy ochreous (less salmon-tinted than in 7’, vesta), pattern 
exactly as in the female, therefore much more yellow throughout 
than in 7’ vesta.

The arrival of this male is especially interesting to me, as Prof. 
Aurivillius was inclined to believe my 7’. rhodesina to be the male 
of 7. mutans, considering that the differences of pattern might be 
sexual: it is now satisfactorily proved that there is no difference 
of pattern between the sexes, but only in the colouring of the 
outer half of the upper surface’; precisely what might have been 
expected, from what we know of the sexes of 7’. hanningtonii and

“ Violet-tipped White” (R. C.). 
An especially well-marked specimen, with bold black spots on 
the under surface. It has recently been suggested that this may 
be a seasonal form of 7. regina, of which Mr. Trimen formerly 
regarded it as a variety; the only odd thing is that typical
