28 ORANGE TIP. 



It is found ill all sorts of situations, in the green lane, and the open 

 pathway or riding in the wood; iu the sunny meadow and the cultivated 

 garden. 



The caterpillar feeds on the Cardambie impatiens, Turritis glabra, 

 Brassica campesh'is, and other plants. 



The wings expand to the width of from one inch and three quarters 

 to two inches. Their ground-colour is white; the upper wings are 

 black at the base, and have a black mark, varying in shape, near the 

 centre. The whole of the space between this, and indeed from a little 

 inside it to the tijj, is a lovely orange colour, bordered on the outside 

 corner with brownish black, irrorated with very minute orange specks, 

 and indented on the inner side. The hind wings are also black at the 

 base. Underneath, the fore wings resemble the upper, excejjt that 

 there is a little dash of very pale yellow near the base, and the dark 

 mark at the tip is exchanged for dull white, barred with dull green. 

 The fore edge has a few small back dots. The hind wings are most 

 elegantly varied with green marks, and yellowish green, the ground 

 colour being white, and some of the veins yellowish. 



The female is without the orange tip ; in other respects she 

 resembles the male, but the green underneath is darker. 



The caterpillar is green, finely dotted with black, and with a white 

 stripe along the side. 



The chrysalis, of a pointed shape, is at first green, which in a few 

 days changes to dull light yellowish grey ; the stripes being brighter. 



This insect varies very much in the extent of the wings, and 

 also in the size and shape of the black spot on the fore wings. 

 Stephens describes one with the black mark on the fore wings almost 

 obliterated, and with a black spot on the upjjer surface of the hind 

 wings. Haworth mentions one as having the orange mark on the 

 upper surface of the fore wings almost invisible ; and Boisduval 

 another, a female, which had an orange sjjot on the under surface 

 of the fore wings, ilr. Robert Calvert, of Bishop-Auckland, has 

 written me word of one he has, which measures only one inch and a 

 quarter across the wings. 



I think it is also more than ordinarily subject to malformation. I 

 have one which has not only the wing, but the antenna on one side 

 smaller than on the other.
