All the above varieties are known in Europe except subglobosa.

 from France orginally, while pallida and rufozonata w'ere first de- 

 scribed from England.

 hortensis, collected by Prof Macoun on Anticosti Island, are some 

 })lain yellow, and others with five brown bands. These will belong to 

 Ititea. and quinquevittata respectively.
