EUTHALIA.

all, spotted with white. The females arc very different, being 

 dark brown, with the tip of the fore-wings spotted with white. 

 From near the base of the inner-margin of the hind-wings 

 a white stripe runs obliquely upwards to the middle of the 

 fore-wings ; this is sometimes absent. Beyond this is a much 

 broader white band, generally extending over more or less 

 of the fore-wings, and outside this is generally a third and 

 more slender sub-marginal line ; occasionally the females are 

 tinged towards the base with the green colouring of the 

 males. On the under surface, both sexes are marked some- 

 what as in the female above, except that the black part of the 

 fore-wings is varied with blue lines and tawny lines or spaces. 

 On the hind-wings, the dark transverse bands of the wings are 

 either entirely tawny or are narrowly edged with black ; some- 

 times, however, the hind-wings are nearly white beneath, with 

 narrow transverse lines. The hind-margin of the hind-wings is 

 generally much paler than above, and often presents a very 

 characteristic mark, which, when present, admits of no mis- 

 take respecting the genus. It consists of two large eyes, 

 with white or blue pupils in black and tawny rings. 



INDIAN AND AUSTRALIAN GENERA ALLIED TO EUTHALIA. 



These form a restricted group closely allied to the African 

 genera of the Limenitis group, but they may be treated as a 

 separate section on account of the remarkable structure of 

 the caterpillars, which are furnished with very long plumose 

 appendages almost like feathers. The numerous and closely 

 allied species of Euthalia and Tanaeria are almost confined 

 to India, the Malay Peninsula, and the adjacent islands, but 

 species of Symphcedra are met with as far east as New Guinea 

 and Australia. They measure from two to four inches across 

 the wings. 



The genus Euthalia, Hiibner, has triangular fore-wings,
