first and second median branches terminating in black spots and 

 the spots on the disc 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 Dclagoa 

 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 T. eris come to hand, the fact that they are true 

 to locality seems to be gradually established on a firmer basis.

c? . Nearly resembles T. 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 T. vesta), pattern 

 exactly as in the female, therefore much more yellow throughout 

 than in T. vesta.

" White- centred, yellow and black- mottled White. Difficult to 

 take and not common " (R. (7.). 



The arrival of this male is especially interesting to me, as Prof. 

 Aurivillius was inclined to believe my T. rhodesina to be the male 

 of T. 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 T. hanningtonii and 

 T. amelia.

" Violet-tipped White " (E. C.). 



An especially well-marked specimen, with bold black spots oil 

 the under surface. It has recently been suggested that this may 

 be a seasonal form of T. regina, of which Mr. Tritnen formerly 

 regarded it as a variety ; the only odd thing is that typical
