112 LLOYDS NATURAL HISTORY. 



The species are black or brown, and measure about two inches 

 in expanse, and the males are adorned with rich blue or purple, 

 differently arranged in various species, sometimes spreading 

 over a great part of both wings from the base, sometimes con- 

 fined to the fore wings, sometimes forming a sub-marginal 

 band, and sometimes forming a sub-costal band on the fore- 

 wings. One species, however, E. margarita (Godart), is nearly 

 white, but some are brown in both sexes. The females are 

 generally brown, with white markings on the fore-wings. The 

 latter in this genus are generally not much longer than the 

 hind-wings, and are not excavated, though sometimes slightly 

 produced on the hind-margin below the tip. The under side 

 of the hind-wings is generally light brown, with two transverse 

 black lines, and a series of ocellated spots within them, con- 

 sisting of a black pupil, sometimes centred with white, and an 

 outer black ring, separated from the pupil by a space con- 

 colorous with the ground-colour. 



Libythina,) Felder, contains only one species, Z. cuvieri 

 (Godart), found on the Lower Amazons, and in the West Indies. 

 It is brown, with the outer part of the fore-wings black, spotted 

 with bluish-white, and measures an inch and a half across the 

 wings. It may be known from any other Butterfly of this 

 group by its very long palpi, and its long hind-wings, which 

 are slightly pointed, the hind margin and inner margin con- 

 verging in a somewhat unusual manner. Bates describes it as 

 not being a forest insect, but as frequenting swampy meadows, 

 where both sexes fly slowly about low bushes. 



Closely allied to Eunica is the one African, indeed, the only 

 Old World genus of this group, Crenis, of Boisduval. The 

 South African species are brown, with tawny markings ; the 

 fore-wings are considerably produced at the tips, and the hind- 

 wings have a sub-marginal row of eyes on the under surface, 

 sometimes indicated above. The species found in Madagascar 

 is similarly coloured.
