Mimicry. — Colonel C. Swinhoe, in his paper on " Mimicry in butterflies of the 

 genus Eypolimnas " (Journ. Linn. Soc. Zool. 1895, p. 339) writes, " The Bolina 

 group of the Nymphalid genus Eypolimnas contains, according to systematists, a 

 number of species. When, however, we look at the group from a biological point 

 of view, we find that all these species can be merged in two distinct species — 

 E. Misqypus, Linn., and H. Bolina, Linn. It is first of all necessary to gain a 

 conception of the appearance presented by these species before the mimetic form was 

 assumed. This we find to be still retained by the male of R. Misipjnis, which is 

 invariably non-mimetic, and that of H. Bolina, which is non-mimetic in India, and in 

 certain other localities. Occasionally the females also revert to the ancestral 

 pattern, and resemble the black males. The non-mimetic males are very similar in 

 appearance, while their mimetic females differ widely. The female of R. Misippns, 

 however, except as a very rare variety which resembles the male in appearance, 

 always mimics the commonest of all the Danainse, i.e. Danais Chrijsippus, Linn., 

 which is common all over India, Burma, Ceylon, the Malay Archipelago, Madagascar, 

 Aden, the "West, South, and South-eastern coasts of Africa, but apparently not the 

 interior : in all these localities H. Misipipus also exists, the female being of the 

 Danais colour and pattern, and where D. Ghrysipims does not exist, B, Misippus 

 is not to be found." " In Africa and at Aden there are several forms of Danais 

 Chrysippus — some without the white-banded black apical patch to the forewings 

 (Danais Dorippus, Klug) ; some possessing this marking, but characterized by white 

 hindwings {Danais Alcippus, Cram.), and also others with the D. Dorippus pattern 

 aud white hindwings. All these forms are mimicked in their several localities by 

 the females of Byp. Misippus.'" " In India the form of female Eypolimnas which 

 mimics Danais Dorij)pus* (without the black and white apical patch) is also found ; 

 it is not nearly so frequently met with as the mimic of the true Danais Chrysippus,j-
