species of Reseda (Mignonette), Cruciferce^ etc., and is more 

 frequently found on wild plants. But there is reason to believe 

 that this also is not a true native, but either was introduced by the 

 Bomans or has established itself by immigration. There is con- 

 siderably more difference between the spring and autumn broods 

 than with Brassicw^ the earlier brood being much yellower,

This species is also very common all over the district, and as 

 the larva feeds on Watercress {Nasturtium officinale) and a

 ground, more than either of the others. This is an undoubted

 variety, Bryonies, was taken at Hartlepool.

Wailes says '■ ' This beautiful Butterfly is generally distributed

 of the larva, Cardamine pratensis, of which it devours the seed
