Breeding of the Nymphaline Genus Eurcdia. 507 
male parent belonged—pairing having ended before cap¬ 
ture or observation of the female. Moreover, it is seldom 
indeed that all the ova normally laid are obtained ; a wild 
female watched or captured, unless immediately or very 
soon after pairing, having usually already oviposited to a 
greater or less extent; so that, in a dimorphic or poly¬ 
morphic offspring, the full relative numbers of the sexes 
and of the respective forms born from one and the same 
mother cannot be strictly ascertained. The possible pair¬ 
ings within the limits of the sub-species Euvalia wahl- 
bergi-mima are four, viz. :— 
1. ^ X $ loahlbergi-iovm. 
2. ^ X ^ mima-loxva. 
3. ^ ivahlhergi-iovvcv x $ mima-iorm. 
4. ^ mima-iovm X $ unhlhergi-iovro.. 
Of pairing No. 1 (both sexes ot loahlhergi-iovra), Mr. 
G. F. Leigh (Proc. Ent. Soc. Lond., 1906, pp. Iv and Ivi) 
has recorded two cases that came under his personal 
notice, viz. one on December 16, 1904, and the other on 
January 23, 1905. 
Of pairing No. 2 (both sexes of mma-form), there is 
the instance of the very closely-similar sexes taken by the 
late Col. N. Bowker (and published in my “ S.-Afr. Butt.,” 
I, p. 285, 1887); and also Mr. Leigh’s record (/.r.) of 
seeing two mima paired on January 27, 1905. 
Of pairing No. 3. (J loahlbergi-iovvo. with $ mwia-ioxnii)^, 
I have no definite instance; but in the “ Entomologist 
for 1882 (p. 9), Mr. A. J. Spiller, a keen collector and 
observer, mentions that in Natal he had taken the ^ 
anthedon ( = luahlbergi) mated with the ^ mima, and vice 
versa,. 
Of pairing No. 4 (J mima-iovva with ^ wahlbergi-^oxwij, 
there are tAvo authenticated cases, viz. Capt. H. C. Har¬ 
ford’s (published by me in Trans. Ent. Soc., 1873, p. 107, 
note, and in “ S.-Afr. Butt.,” I, p. 283), and Mr. H. M. 
Millar’s in July 1890.* 
The occurrence ot certainly three, and most probably 
* Mr. A. D. Millar, wlio communicated tins case to me at the time, 
now writes :— I have seen initncL and wcthlber^i three times paired, 
but did not note and cannot remember which form was the ^ and 
which the 9.” Mr. Millar sent me the 9 wahlbergi of the 1890 
case, with the information that his brother, Mr. H. M. Millar, had 
captured it paired with a d mima.
