APEIL. 97 



PONTIA CARDAMINES. (Plate VI.) Orange Tip. The 

 primary wings in this pretty species are white, dusky at the 

 base, with a small crescent-shaped spot in the middle, and 

 a patch of black round the tip ; the outer half of the wing 

 is deeply tinged with orange in the male, but not in the 

 female ; the hinder wings are alike in both sexes ; on the 

 upper side they are dusky at the base, the surface presenting 

 traces of the markings underneath, which consist in spots 

 of green, powdered with yellow. The caterpillar is green, 

 with a white line on each side, and feeds on several Crucifer- 

 ous plants. This insect differs slightly from other Pontias 

 in the form of wings, which in the anterior pair are more 

 rounded, and by the under side being variegated ; the ter- 

 minal joint of the palpi is also shorter. The P. cardamines 

 measures about an inch and a half.
