214 LEPIDOPTERA. 



portions of salt marshes, or on the sea-banks ; found in some 

 plenty in such sj^ots on both banks of the Thames estuary ; 

 in Kent and Essex ; also in Sussex, Suffolk, and Norfolk ; 

 but I have searched in vain on other parts of our coasts, 

 where the food-plant is most abundant, and have no know- 

 ledge of its occurrence beyond these five counties, in any 

 part of the United Kingdom. Abroad it seems only to be 

 recorded from Northern Germany and Livonia.
