P. margincguttata. Mr. Paget gave me a specimen which he 

 found in a garden at Great Yarmouth upon Ruscus aculeatus (pi. 

 489.). 



P. ccerulea flies well in the sunshine, and is to be met with on the 

 leaves of plants in the heat of the day. I have taken it in June 

 near Ambleside ; July, Coombe-wood ; September, on heath near 

 Linton, Devon ; and at Niton on the Wormwood. 



In the cabinet of the Zoological Society is a species from Dr. 

 Leach, bearing the name of P. picta : it agrees tolerably well with 

 the Fabrician (lescription, but I believe that Dr. L. was not satisfied 

 of its authenticity as a British specimen. 



The plant is Erysimum chciranthoidcs, Treacle Worm-seed.
