282 LEPIDOPTERA. 



lateral and anal tufts very small. Fore wings broad and 

 ample ; costa fully arched ; apex very bluntly angulated ; 

 hind margin rather oblique, gently curved, and faintly un- 

 dulating or crenulated ; dorsal margin rather full and 

 strongly ciliated ; colour rich green ; first line very obscure, 

 erect, but often not reaching the costa, white, shaded off 

 inwardly, but outwardly edged with rather darker green ; 

 second line not very distinct, disposed in crescents between 

 nervures throughout, white, inwardly edged with darker 

 green ; midway between it and the hind margin is a faint 

 series of cloudy white spots, forming an imjierfect or obscure 

 subterminal line ; discal spot an erect dark green crescent, 

 not very distinct ; cilia green, rather short. Hind wings 

 large, rounded and crenulated behind, rather squared at the 

 anal angle, of the same green colour as the fore wings ; 

 central spot an obscure dark green streak ; in the middle of 

 the wing a transverse curved row of white crescents, and 

 beyond this is a more indistinct row of white cloudy spots ; 

 cilia green. Female rather larger and stouter, with simple 

 antennae, otherwise closely similar. 



Underside of the fore wings rather deeper fuller green 

 than the upper, crossed in the middle by a still deeper 

 green stripe ; dorsal margin paler. Hind wings rather 

 paler, and faintly showing the transverse rippled line, and 

 row of spots of the upper side, in a paler shade of green. 

 Body whiter green ; legs brighter green, but the tarsi 

 brownish- white. 



Usually only variable in the distinctness of the transverse 

 white lines and crescents, but Mr. B. A. Bower has a speci- 

 men in which the hind wings are clear smooth tchite, except 

 a large green blotch near the base. In 1866 and 1867 Sir 

 J. T. D. Llewellyn captured in the neighbourhood of Neath, 

 South Wales, three specimens of a rich cream colour ; whether 

 they had emerged from pupa of this colour, or had become 

 faded while alive, there was, apparently, no evidence to show. 

 Usually the colour is fairly well maintained during life, but
