The ova of the females are said to vary from yellow to orange 
in colour. 
The following description of the egg of this species was made 
by Mr. F. W. Frohawk from a single specimen found attached to 
a female obtained by Consul Sharpe at Zomba:— “The ovum, of 
the usual Argynnis form, conical in shape and measuring ~; inch 
high, with about twenty longitudinal keels, irregular and varying in 
length ; some running for only two-thirds the distance from base 
to apex, others terminating before reaching the summit, eight only 
extending the entire length. It is ribbed transversely by about 
twenty in number, the ribs being irregularly distributed and widely 
separated near the summit, gradually becoming closer and shallower 
until finally disappearing at the base. 
‘“‘In general structure this ege very closely resembles that of 
A, selene (very much more than that of either A. euphrosyne or 
lathonia), the number and formation of the keels and ribs being 
similar in both species. It differs most from A. lathonia, A. ewphro- 
syne being intermediate between A. smaragdifera and A. lathonia.”
