Breeding of the Nynvphaline Genus Euralia. 503 
mima —all received with the imagines in Mr. Millar’s 
consignment. 
Second Experiment. — Offspring reared, from ova laid 
hy one example of Euralia wahlbergi. 
On the same date (March 21, 1909) as that on which 
the two g ? deceptor were captured, Mr. Millar observed a $ 
wahlbergi ovipositing on and in the immediate proximity 
of Fleurya plants. He at once followed up this example, 
and carefully collected ten eggs laid by her, securing them 
consecutively as they were deposited. All these eggs 
hatched on the 25th; and on the 31st the young larvae 
were noted as being dark-blackish, with short black spines. 
On April 5, after moulting, the larvae were quite black, 
with on each segment, placed anteriorly, a very thin 
ti'ansverse yellowish band or half-ring ; the spines, spring¬ 
ing from these half-rings, were more developed, but still 
black ; and the two long divergent cephalic horns were 
fully formed and also black. The moult of April 10 was 
followed by a great change in the aspect of the larvae, the 
segmental yellowish half-rings being wider and more con¬ 
spicuous, and the head and its horns, together with the 
spines, the legs and the pro-legs, being all brownish-yellow. 
On the 14th, five of these larvae pupated, and the remain¬ 
ing five on the l7th. One of the pupae died ; but all the 
rest produced the imago in the following order, viz.:— 
April 24— %vahlhergi-ioxmy 1 
„ 25— mima-ioxm, S $ 
„ 26— mima-iorm, 1 1 
„ 27— ^ucthlbergi-ioTxn, 1 1 
,, 29— wahlbergi-iorm, 1 [deformed]. 
Total offspring of a single example of the ^ of the 
wahlbergi-ioxxn :—4 wahlbergi (2 ^ 1 1 sex unde¬ 
termined), 5 mima (4 ^ 1 ^). 
This extremely interesting result, clearly demonstrating 
the species-identity of the forms wahlbergi and mima, is 
the more striking because of the small number of the 
brood being not far from equally divided between the two 
forms, and at the same time including both sexes of each 
form. Mr. J. H. Burn’s photograph (reproduced on Plate 
LXII) gives in miniature all the examples of this brood, 
with the exception of the deformed one—the sex of which 
was not noted—and also dried specimens of two full-grown
