22 OBEEN VEINED. 



The female is generally smaller than the male, and the wings are 

 more rounded. They are of a light greenish white colour, veined 

 with dusky black ; the tips dusky black, and there are two spots of 

 the same towards the outer margin of the wingj the lower one, at the 

 lower edge, running into a wide streak, which runs up to the base 

 of the wing. The hind wings are also streaked with dusky, but more 

 faiutly, and there is one spot on their upper edge, in a line with the 

 two on the upper wings: underneath, the streaked nerves shew through, 

 as also the spots. The hind wings are pale yellowish, the nerves 

 streaked with dull greenish on both sides, widest above, and each 

 running off to a point at the outer edge. 



The caterpillar is of a dull green colour on the back, the sides 

 brighter, with red dots placed on yellow spots on each segments. 



The chrysalis is greyish or yellowish green with black spots. 



This is another very variable insect. One has been described as a 

 separate species, under the name of ' Papilio napeee' and 'Pontia napea^.' 

 The male has the whole upper surface of the fore wings white, with 

 the tip, a spot, and two or three triangular-shaped markings on the 

 hind margin, black; the hind wings white, with the nerves near the 

 base widened and greenish. Underneath, the fore wings have the 

 nerves rather widened into greenish streaks, with two ash-coloured 

 spots placed transversely, and the tips yellowish; the hind wings pale 

 yellowish with one deeper streak. 



The female has the fore wings, with the tips, and three spots, one 

 of which is nearly triangular, dusky black; the hind wings clearer 

 yellow. Underneath, the hind wings have the streaks on each side of 

 the nerves more or less wide in different specimens. 



Another variety, also erroneously made into a species, under the 

 name of 'Pontia sabellicte,' has the veins strongly margined ou each 

 side with brown, and the fore wings of a rounded shape in some 

 sjiecimens, and in others only so on the lower part of the margin, 

 which is therefore widened more than ordinarily. 



The male of our present species has been known with the wings of 

 the rounded shape which usually is characteristic of the females. 



The figures are taken from specimens in my own collection, one of 

 them the very unusually small one already referred to.
