pointed out in the paper above mentioned, and has more 
fully of late described to me) the same state of things is pre- 
valent, extensive Millerian inedible associations among (¢.g.) 
the species of the three main groups into which the old genus 
Eupleea has been divided, being “‘attended and surrounded ”’ 
by numerous true mimics belonging to edible groups. ‘lhe 
far poorer Ethiopian region has, to my knowledge, yielded 
as yet only a very few series including both inedible and 
edible imitators; but in the group of which the Danaine, 
Amauris egialea, is the centre, there appears the exactly 
similar Danais (Melinda) morgeni ; and in the same way the 
much-mimicked Amauris echeria, var., has in East Africa a 
protected companion in the female Acrwa johnstont, while 
there is some reason for thinking that the widely-distributed 
Acrwa encedon is modified in resemblance to the dominant 
Danais chrysippus. Perhaps the most remarkable of these 
associations is that which surrounds the abundant and 
extremely conspicuous slow-flying diurnal Lithosiid moth, 
Aletis helcita. The apparently protected analogues of this 
insect are the closely similar Lithosid, Phaayarista helcitoides, 
and Agaristid Husemia falkensteinti, while the Batesian 
mimickers are found in the Nymphaline butterflies, Muphadra 
ruspina and fH, eleus, and the aberrant Lyczenid, Liptena 
sanguinea. Another point of interest in this last-named 
series is its great similarity in colouring and marking to that 
which is headed by Danais chrysippus, the differences being 
merely that in the Aletis set the red ground-colour is brighter, 
and the white spots in the black margins are larger; so that 
from the aspect of warning of distastefulness to enemies the 
two sets may be regarded as practically but one. 
Among the Batesian mimicries in the Ethiopian region, 
I wish to revert more fully to the very striking and instructive 
case, already briefly referred to, presented by the females of 
the Merope-group of the genus Papilio, because it has largely 
gained in interest by the increase of our knowledge in recent 
years. In 1867, when I wrote the paper above mentioned,* 
only three forms of the Merope-group were known, vid. : the
