178 BRITISH BUTTERFLIES AND MOTHS 



the centre of the wing is a small dark grey dot, and 

 two others (forming a triangle with it) are placed 

 between it and the hind margin. The hind-wings are 

 whitish, or very pale grey, towards the hind margin,

The larva is of a greyish-ochreous, with whitish 

 dorsal and subdorsal lines, the latter edged above with

 dusk, and can often be collected very freely. 



There are numerous other allied species, but the dif- 

 ferences are too minute, and they are so little likely to 

 attract the attention of beginners, that it is unnecessary 

 to introduce any notice of them here.
