56 THE BOOK OF BRITISH BUTTERFLIES. 



the base of the wing is a black spot crossed by a white 

 streak. These markings are to some extent reproduced 

 on the under-surface, but there powdered with yellow, 

 and in addition there is a dark spot near the anal 

 angle, -which also shews on the upper surface of the 

 female.. The upper surface of the hind-wings in the male 

 (Fig. 37) bears only a few black scales on some of the 

 nervures, but in the female (Fig. 38) it is chequered with 

 black on the hind-margin, and clouded with the same 

 elsewhere. The chief beauty of the insect, however, is to 

 be found on the under-surface of the hind-wings (Fig. 39), 

 the markings on which form a beautifully chequered 

 pattern of green and white. The green, as in the Green- 

 veined White, is caused by a sprinkling of yellow scales 

 over a black ground. The white of the under-surface 

 of all the wings is also in places powdered with yellow. 



Euchloe, Hiibner ; Anthocharis, Bdv. 



Euchloe is the recognised name of the genus to which 

 our next butterfly belongs, though by many Anthocharis * 

 is * preferred. Why it has deserved the latter name it 

 is rather hard to say, for what butterfly does not delight 

 in flowers? But perhaps the name refers to the delight 

 *we should take in tracing the resemblance that the little 

 Orange-tip bears to a flower that has apparently taken 

 wings to itself with the intention of no longer being 

 fettered down to earth ! 



E. cardamines, Linn. (Orange-tip, or, according to the 

 specific name, the butterfly of the Cardamine, or Cuckoo- 

 flower) (Figs. 42 to 47), is, for several reasons, one of 

 the favourites of the entomologist. It is not only very 

 common, but, at the same time, very delicately beautiful.
