SOUTH-AFRICAX BUTTERFLIES. 
more constantly complete than in ^, where some of the middle spots 
are often wanting. 
There is a slight approach in several examples (of both sexes) to 
caudation of the hind-wing on first median nervule and submedian 
nervurOj and in specimens from Delagoa Bay (two $ s, three $ s) this 
tendency is more pronounced. 
This near ally of Tdikosama is distinguished by its darker, more asliy 
ground-colour of the upper side, with (in the ^ constantly and in the $ occa- 
sionally) pale-grey submarginal marking, which is always restricted (whether 
grey or yellow) in the hind- wing to a narrow hind-marginal stripe ; by the 
absence or slight develoiDment of any basal suffusion ; and on the under side 
by the larger and brighter spots of the hind-wing, and the larger silvery-white 
centres of the spots of the fore-wing. The under-side colouring is also 
(especially in the ^ ) much paler, and the spots of the third transverse row (all 
but obsolete in the $ ) of the hind-wing are distinctly sagittiform instead of 
rounded or sublunulate. The females in which the stripes are grey come from 
Delagoa Bay, as well as one in which that of the fore-wing is half grey and 
half yellow. 
Mr. Walter Morant was the first to bring this form to my notice, in the 
year 1872 ; the two males he sent having been taken in the upper districts 
of Natal in September 1870. Mr. J. M. Hutchinson and Colonel Bowker 
have subsequently forwarded examples of both sexes from the same region ; 
and I have received others from the Transvaal, collected by Mr. T. Ayres, and 
from Delagoa Bay, taken by Mrs. Monteiro.
