DESCKIPTIVE NOTICES OF CONSPICUOUS SPECIES 95 



The expansion of the wings is about 1 J inches. The 

 fore-wings are white, with the tip blackish, and a small 

 spot near the centre. The male has, in addition, the 

 apical half of the wing of a deep orange. Hence the male 

 is one of our gayest butterflies, whilst the female, to an 

 unpractised eye, might pass for the ordinary White ; but 

 in both sexes the underside of the hind -wings is white, 

 prettily chequered with yellowish -green. (The figure on 

 Plate I. represents the upperside of the male.) 



The larva is green, with a whitish stripe on each side. 

 It feeds in July on Turritis glabra, Cardamine impa- 

 tleiiSj and other Cruciferss. 



The perfect insect makes its appearance in forward 

 seasons at the end of April, and may be met with 

 throughout May enlivening by its presence many a 

 grassy lane, then in its first burst of spring verdure, 

 when our native songsters are causing the country to 

 resound with their pleasant warbles. 



The Wood White Butterfly (Leucophasia sinapis) is 

 rather a local species, frequenting woods. It occurs in 

 various parts of the country. Its flight is very weak. 

 It may be known by its small size, by the spotless white 

 wings, the tip of the fore-wings being only clouded with 

 blackish.
