Amauris dominicanus and Danais chrysippus, almost as closely 
as do the hippocoonoides and trophonius females of P. cenea, 
but yet retain on the hindwings the fully-developed tails 
possessed by the male and the unmodified female.* One 
would naturally suppose that these conspicuous appendages 
to the hindwings, never found in the Danaine but so 
characteristic of many groups ef Papilio, would have been 
among the first features to be lost in the process of assimila- 
tion to the Danaine models; and, as Prof. Kheil mentioned 
in his paper, that the tails in the specimen of ‘ niavioides” 
were injured, but had been restored in the figure, I felt a 
little doubtful about them, and ventured recently to address 
him on the subject. He most obligingly answered my 
inquiries, stating that the two forms of female were still in 
his possession, and that while the tails of the ab. niavioides 
were injured, as originally pointed out, those of the ab. 
ruspine were intact and are correctly delineated in Haase’s 
figure, which—as well as that of niavioides—was drawn from 
the actual specimen, lent by Prof. Kheil. It is to be noted 
that the tails are uniformly black, in accord with the broad 
hindmargins, instead of being pale yellow with a short 
median streak of black, as in the female of the male 
coloration. Prof. Kheil further informed me that the dis- 
coverer of these forms, the late Dr. A. Stecker, who 
collected at Lake Tana, brought together seven males, two 
females like the male, and one only of each mimetic form of 
female, and that he reported the male as very common, 
while the females seldom occurred. 
This persistence in Abyssinia of the original female 1. 
antinorii, side by side with two mimetic forms of the same 
sex retaining her outline of hindwings but far divergent 
from her in advanced imitation of two very different Danaine 
belonging to distinct genera, is strong confirmatory evidence 
of the view I advanced as to the development of the various 
tail-less mimetic African females of the group from the 
ordinary male-like type of female solely prevalent still in 
the Malagasy sub-region. From analogy with what occurs
