BATH WHITE. 89 



This fact should encourage the collector, especially 

 when at work on the south-east coast, to net all the 

 middle-sized Whites that come within reasonahle dis- 

 tance of course letting them off again, if they are not 

 of the right sort. 



The wing markings on hoth the upper and undei 

 sides are, though simple, extremely elegant and chaste. 

 The female, which is the sex figured, has the upper 

 wings beautifully spotted with black. The hind wings 

 are bordered with a row of black spots, and clouded 

 towards the centre with a faint tint of the same. 



The male is distinguished by the absence of the 

 black spot nearest to the lower margin of the front 

 wing, and of the black marginal spots and grey cloud- 

 ing of the hind wings. The markings of the under 

 surface, however, show through their substance rathei 

 plainly. 



In both sexes, the ground colour of the wings is 

 milk-white. But the chief decoration is reserved for 

 the under surface, which is chequered, in a manner not 

 easily described, with a soft but rich green tint upon 

 white, relieved here and there by a few black touches. 



We are informed by Lewin, that it was named the 

 Bath White from a piece of needlework executed at 

 Bath, bv a young lady, from a specimen of this insect, 

 said to nave been taicen near that city. But the 

 south-eastern corner of England, and more especially on 

 the coast, seems to be the head-quarters of this valued 

 fly, lending probability to the supposition entertained
