42 THE BUTTERFLIES OF THE BRITISH ISLES. 



or other common butterfly, when seen on the wing, it is very 

 different from any of our other species when seen at close 

 quarters. In the greenish mottling of the under side of the hind 

 wings, the male has some likeness to the female Orange-tip, but 

 on the Bath White the green is heavier and less broken up. 

 On the upper side of the fore wings the black markings comprise 

 a spot, sometimes divided, at the end of the cell, and a patch on 

 the tips of the wings ; the latter enclose spots of the ground 

 colour. The markings of the under side show through blackish 

 on the upper side of the hind wings. The female differs from 

 the male in having a black spot between veins i and 2 of the 

 fore wings, and the markings of the hind wings are blacker, 

 especially on the outer area. 



The egg is stated by Buckler to be of a bright pinkish-red 

 colour, agreeing in this respect, as well as in size, with the 

 anthers of the flowers of mignonette, upon which plant it is laid 

 in an upright position. The shape is compared to that of an 

 acorn without the cup, and it has twelve or fourteen rather 

 prominent ribs. 



The full-grown caterpillar is bluish-grey, dotted with glossy 

 black warts, from each of which there is a short blackish hair. 

 The lines along the back and sides are yellow, or white spotted 

 with yellow. Head yellowish, dotted with black, and hairy. 

 August and September. It feeds on garden as well as wild 

 mignonette {Reseda), 



The chrysalis is at first similar in colour to the caterpillar, 

 but it afterwards becomes whitish. It has numerous black clots, 

 and is marked with yellow along the sides and on the back of 

 the thorax. 



The above descriptions are abridged from Buckler's more 

 detailed account of the life-history of this species. Of the 

 caterpillars resulting from thirty-three eggs, only two attained 

 the chrysalis state, in September. One of these turned black 

 and died in November, and from the other a butterfly emerged
