which stands close to it, border a brown band. From this to 

 the fringes the ground-colour is pale ashy-grey. The fringes 

 are dark brownish, and very slightly dentated. In front of 

 them is a row of detached brown dots. The hind-wings are 

 pale red, with the black central band curving uninterruptedly, 

 but terminating at a distance from the inner margin. The 

 marginal band is broad externally, and narrows as it passes 

 inwards. The fringes are white, and dotted with brown. 



The larva feeds on willow. It is ashy or reddish-grey, 

 shagreened on the sides with delicate transverse folds, gene- 

 rally with a faint M-shaped mark on the back of each segment. 

 The tubercles are yellowish, and there is a blackish or brownish 

 red elevation on the ninth segment, which is sometimes dusted 

 with orange. On the twelfth segment there is also a dark 

 brown bifid elevation. The spiracles are white, bordered with 

 black, and there are short grey lateral fringes. The belly is 

 pale grey with black spots. The head is flat, grey narrowly 

 bordered with black, with two small brown or orange-yellow 

 dots above. It is found in May. The pupa is slender, 

 brown with a blue efflorescence. The moth appears in August.
