220 LEPIDOPTERA. 



Underside of the fore wings pale leaden-brown ; costa 

 near the apex dotted with white. Hind wings smoky white. 

 On the wing at the end of Jane and in July. 



Larva yellowish white ; head pale brown ; dorsal plate 

 pale, with black dots ; raised dots hardly visible ; anal plate 

 of the body colour. (Herr Disque.) 



August and September in the green seed pods of Ononis 

 spinosa (restharrow). 



Pupa in an oval cocoon of silk and sand, lying in the sand 

 underneath the plants of restharrow. 



This delicate looking insect seems to be almost confined to 

 the coast, but is found inland on the chalk hills about 

 Ci'oydon and elsewhere in Surrey. It sits during the day in 

 and under the thick flat patches of restharrow, and may 

 sometimes be secured by separating the tufts and looking 

 closely where it may be sitting among the roots and dead 

 leaves. At sunset it flies over the same plants, and from 

 the light colour of its hind wings is easily seen. Besides the 

 localities already mentioned, it is to be found on the coasts 

 of Kent, Dorset, Devon, Essex, Suffolk, and Norfolk, usually 

 on the more settled portions of coast sandhills. So far as I 

 know, this is the extent of its range in these Islands. 

 Abroad it is common through Central Europe, Piedmont, 

 the north of Spain, Sweden, Armenia, and Asia Minor.
