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, Hubner ; 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.
