This pretty pug is rarely seen in the perfect state, and most 



of our cabinet specimens are bred. The larva feeds upon 



Linaria vulgaris (Yellow Toad-flax), which is not a rare plant 



in either county, and I think if this be gathered when in full

from larvae on Toad-flax at Seaham Harbour ; and Mr. Gardner 



has got a few specimens near Hartlepool.

The larva of this pug feeds upon Digitalis purpurea (Fox-

 it certainly does not grow there generally, nor in any of the 

 other Denes or ravines on the Durham coast; in which we have 

 both collected carefully for nearly fifty years. Fox-glove is 

 common on the higher land in the west of both counties, 

 towards the Cheviots in Northumberland, and in Upper Tyne- 

 dale, Weardale, and Teesdale generally. Mr. Sticks found the
