identical with malindeva Waterh. and Lyell, from N.W. 
Australia. 
In the discussion which followed Mr. P. A. Buxton raised 
the question how far this was a question of mimicry at all. 
Prof. Poutron said that he believed the superficial resem- 
blances exhibited by Mr. Talbot to be mimetic because they 
followed the rules of mimetic resemblance elsewhere. For 
example in Africa members of specially protected groups 
resembled each other and often resembled those of other 
eroups, while both were-resembled by species of groups not 
known to be specially protected; when the resemblance 
differed in the two sexes the females bore the stronger likeness 
and were often mimetic while the males were non-mimetic. 
Conspicuous among the mimics of Danaines and Kuploeas 
in the Old World tropics were females of the Nymphaline 
genus Hypolimnas with non-mimetic males. 
The island groups exhibited by Mr. Talbot followed the 
above rules; they showed strong resemblance between mem- 
bers of the specially protected group of Euploeas, and mimicry 
of them by the females but not the males of the species 
of Hypolimnas in the same island. Just as the patterns 
of representative groups differed in different parts of Africa 
so they differed in passing from one island to another—the 
differences running through all the members of each local 
group and being thus independent of affinity. Prof. Poulton 
had furthermore shown that in Fiji the resemblance of the 
female Deragena proserpina Butl., to Nipara eleutho Quoy. 
was carried further than in its male and that these common 
Euploeas were resembled by the less common Danaine Tiru- 
mala neptunia Feld. (Proc. Ent. Soc. Lond., 1919, p. Lxix). 
Here too the resemblance was especially strong in the females. 
Finally the prevalence of dyslegnic patterns was as char- 
acteristic of these island mimics as of the better known 
examples from continental areas. 
MARGARODES UNIONALIS IN Brirain.—Mr. RoBert ADKIN 
exhibited a specimen of Margarodes unionalis that was taken 
at sugar at Arlington, a village about seven miles inland 
from Eastbourne, on October 3, 1920. The species appears 
to have been first recorded in this country by Stainton in
