BATH WHITE BUTTERFLY. 
the base. The antenna; are whitish, variegated with 
black. 
The caterpillar frequents the different species of 
Brassica ; also wild Mignonette ( Reseda lutea), 
Thlaspi arvense, and other cruciferous plants. It 
is of a dull blue, according to Godart’s description, 
bordered with yellow, and covered with black points ; 
the head clear green, with yellow spots and black 
points. The chrysalis is at first greenish, but af- 
terwards becomes grey. 
Although recorded from a remote period as a na- 
tive of Britain, this insect still continues to be classed 
among our rarest kinds. It is noticed by Ray as 
having been found near Cambridge : it has likewiso 
occurred at Hampstead in Middlesex, and in the 
neighbourhood of Bristol. More recently it has 
been taken, both by Mr Stephens and Mr Le 
Plastrier of Ramsgate, in the meadow under Dover 
Castle, in the month of August. We are told by 
Lewin, that it was named the Bath White, from a 
piece of needlework, executed at Bath by a young 
lady, from a specimen of this insect, said to be taken 
near that place.
