Breeding of the Ny'ni'phalinc Genus Euralia. 505 
to express the hope that he would repeat, if possible, a 
breeding from mima ova, as I thought it highly probable 
a second result would prove to be quite different from the 
first one ; but I learned subsequently that he had already 
anticipated my suggestion. 
Fourth Experiment. — Offspring reared from ova laid 
hy a second example of Euralia mima. 
On November 21, 1909, Mr. Millar met with a ^ mima 
ovipositing at Mount Edgeumbe, and secured consecutively 
eleven eggs one by one as soon as laid. These were care¬ 
fully placed on the food-plant and kept under regular 
observation; they all hatched, and the larvae duly fed up 
and pupated. Without exception the pupae all yielded 
the imago, the butterflies emerging in the following order, 
viz.;— 
December 19— mima4oxm, 1 
„ 20— mima-iorm, S $ 
„ 20— wahlbergi-form, 2 $ 
„ 22—7?ima-form, 1 3 ^ 
„ 22— tvahlhergi-ioxm, 1 
Total offspring of a single example of the ^ of the 
mima-ioxxxi : 8 mima {b $ f 3 ^ ^), 3 icalilhergi $). 
This second result of breeding from the ova (11) of a 
single mima —in such strange contrast to the earlier one 
in which exclusively mima was obtained from between 
three and four times as numerous ova (39) of a single 
example of the same form—conclusively confirms the 
result of the converse experiment described above (p. 503), 
in which 4 (2 ^ 1 1 sex undetermined) of the waldhergi- 
form, and 5 (4 ^ 1 $) of the mima-ioxxa were produced 
from 9 of the 10 eggs laid by one wahlbergi. It places 
beyond question the fact so long suspected but until 1909 
never proved, of the absolute species-identity of the two 
forms under notice; * and it incidentally illustrates the 
* Evidence exists to show that my friend and correspondent, Mr. 
William D. Gooch, who collected largely in Natal in the years 
1873-78, and attended specially to the larvae and pupae of Lepi- 
doptera, was close upon discovering the species identity of the two 
Euraliae in question. As I mentioned in “ S.-Afr. Butt.,” I, p. 281 
(1887), in Mr. Gooch’s extensive series of drawings and notes, there 
are two pencil outlines and written details of a larva stated to have 
resulted in “ Eiiralia mima or dubia,” and one of the figures of the 
larva is represented on the food-plant, which is unmistakably a 
stinging-netlle.
