black-browa with three large dull white spots near the 

 middle, followed by a curved transverse series of similar 

 dots ; another series of still smaller dots lies along the hind 

 margin ; cilia shining black-brown. Female similar. 



Undersides of all the wings very like the upper, but there 

 is an additional white spot on the dorsal margin of the fore 

 wings, and much more white in the basal half of the hind. 

 Body dark grey, slenderly barred with white ; legs grey and 

 white. 



On the wins; in June, July, and the beginning of August. 



Larva spindle-shaped, the anal segment produced, and the 

 anal jjrolegs extended behind ; head small, rather projecting, 

 pale brownish-j-ellow ; body greenisli-white with bright 

 gi'een dorsal and subdorsal stripes uniting in a green bar on 

 the second segment ; ventral prolegs slender and rather splay ; 

 raised dots white and the skin very glassy in appearance. 

 When quite full grown the head becomes faintly brown, the 

 body pale primrose-yellow and the lines almost transparent. 



August to October on Stacliys sylvatica, S. arvcnsis, and 

 ,S. ainhigva (species of woundwort), feeding on the leaves, 

 eating out wide spaces from the underside, where it forms an 

 open tube or chamber by partially rolling the soft portion of 

 the leaf. It spins its silken cocoon in a hollow or rotten 

 .stick, or a bit of dead stem of the food-plant or of an 

 umbelliferous plant, and there lies unchanged until the 

 following May or June. 



Pupa apparently undescribed. 



The moth has unusually secret and retiring habits. It 

 spends the day in the midst of a thick tuft of Stacliys close 

 to the ground, very often in a ditch, or in the thickest tangle 

 of a mixture of bramble and woundwort, and even when 

 disturbed keeps fluttering timidly closer into the same 

 hiding-place, and creeping in among the rubbish and dead 

 leaves. If driven out of this patch it flies hastily to the
