Time of Appearance — Imago. April-August. Larva. May-September. 

 Food-plant. Cruciferce, Tropceolum, and Reseda. 



There seems some reason to doubt whether this species and P. Brassicce are 

 not introductions in the north, since they are probably never found at any dis- 

 tance from cultivation, nor the larva upon any but cultivated plants.

 of Aporia craicegi L., a species that is British and goes far north in Europe 

 (even to southern Lapland), is curious.

C. PalcEno L. may perhaps occur on some of the unexplored mountains. 



Parnassius Apollo L. is said to have been seen and captured in Scotland, 

 but we fear that we cannot yet include this fine species in our list The food- 

 plant of the larva is said to be some of the alpine or subalpine species of Semper- 

 vivum. There are no indigenous species of this genus in Britain, but the Rose- 

 root (Sedum Rhodiola L.J, another plant belonging to the same natural order
