PALE CLOUDED YELLOW. 15 



the ground-colour is sulphur yellow, with a black central spot, 

 and an irregular broad band, edged with light pink on the 

 outside margin, in which is an interrupted series of spots of 

 the same hue as the ground-colour of the Avings, The hind 

 wings have a light orange-coloured central spot, and the margin 

 at the corner is partially and irregularly bordered with black, 

 edged with light pink. 



In the female the ground-colour inclines more to very light 

 cream-colour: underneath, the fore-wings are pale yellow, the 

 outside corner, orange yellow; a roAv of blackish transverse 

 marks runs parallel to, but at some distance from, the outside 

 margin. The central spot is black, yellow in the centre. The 

 hind wings are orange yellow, with a large silvery spot, accom- 

 panied by a small eye-like dot, surrounded with reddish. There 

 is a row of small blackish spots between these and the hind 

 corner, round the edge of the wing. 



The caterpillar is of a velvet green colour, with two stripes 

 of yellow on the sides, and black dots on the segments. 



The chrysalis is green, with a yellow line on the side. 



Varieties of this insect have occurred: one is described as of 

 a whitish colour; another with the rich sulphur band that 

 divides the broad black margin at the outside corner of the 

 fore wings, uninterrupted, and the central spot of intense 

 blackness; the hind wings more than ordinarily rounded at the 

 margins, very faintly marked with black, and the central spot 

 or spots scarcely discernible: the size of the insect smaller 

 than usual, and its whole contour different. Another was seen 

 which, as well as couM be observed, was of a very rich sul- 

 phur-colour, and the outside corner margins, and central spot 

 of a rather deep red. 



The figure of the female is taken from a specimen in my own 

 cabinet.
