go LEPIDOPTERA. 



Extremely constant in colour and (absence of) markings. 

 On the wing in Jul}' and August. 



Larva plump and cylindrical, much rounded behind, 

 tapering at the anal segment, and from the second to the 

 head, which is small, shining brownish-ochreous, with two 

 black dots in front of each lobe ; ocelli black ; body soft and 

 velvety, reddish or red-brown, slightly mottled with grey ; 

 dorsal markings almost linear, widening a little, but narrowly 

 lozenge-shaped near the end of each segment, and having on 

 this widest part a round pale spot of dirt}^ ochreous ; a slight 

 indication of the usual transverse marking is faintly visible 

 on the twelfth segment, and more faintly still on some of the 

 others ; sides of the body much mottled with grey atoms, 

 more especially along the spiracular region ; on the hinder 

 portion of each segment is a round, pale spot, though less 

 noticeable than that on the dorsal marking ; subspiracular 

 stripe and ventral surface pale pinkish ochreous-brown, the 

 latter paler ; usual raised dots most minute, black ; spiracles 

 black. Another variety is of a deep brownish ochreous-pink, 

 freckled and mottled with grey and pale flesh colour. 



"When very young the head is shining blackish-brown ; 

 body purplish-brown, darkest on the back, and with a plate of 

 darker brown on the second segment ; as it grows it becomes 

 of a brownish-olive colour, and gradually assumes the adult 

 colouring, taking shades of crimson-brown and chestnut as it 

 progresses. (Condensed from W. Buckler). 



August or September to June, on heather, birch, bilberry, 

 knot-grass, grass, and other low plants ; hibernating when 

 very small ; feeding at night. 



Pupa undescribed — subterranean. 



The moth comes readily to sugar at night in its very 

 restricted localities ; also to heather-bloom, the flowers of 

 grasses, and occasionally to tansy-blossom. Excessively local, 

 and restricted mainly to mountain districts, from 700 feet
