agreeing with the margin. In some specimens a pale reni- 

 form cloudy spot' indicates the usual discal spot, which in 

 this group is so often suppressed, and in rare instances a 

 second cloudy spot before it is visible in the discal cell. Hind 

 wings rounded, reddish-white or very light reddish-brown, 

 paler at the base ; a rather broad darker submarginal band ; at 

 the anal angle a patch of bluish glistening scales edged with 

 black, and above it two black spots ; cilia at this portion 

 chestnut, remainder pale red-brown. Female with antennae 

 slightly indented, a little stouter, otherwise quite similar. 



Underside unicolorous pale reddish-brown, the hind wings 

 rather the paler ; cilia of both dark brown ; body and legs 

 chestnut-brown ; anal tuft rather lobed, darker red. 



Variation in this species appears to be somewhat climatal. 

 The type, as described, is rather constant in all the southern 

 and eastern districts of England ; but specimens sent by 

 Major J. N. Still from Dartmoor, Devon, have in some cases 

 the reddish colour much clouded and hidden by deep 

 umbreous, and the prominent tuft black ; in others the 

 general colour umbreous with the darker portions suffused 

 with a bluish bloom. Durham specimens sent by Mr. J. 

 Gardner are of a very smooth clear dark red, but with the 

 prominent tuft black ; from Pembrokeshire they are of a rich 

 dark chestnut with strong umbreous markings. In Scotland 

 variation seems to take three directions — paler reddish to 

 pale buff, with the cilia darker ; paler umbreous-brown 

 without any tinge of red ; and bright chestnut without darker 

 markings, the prominent tuft being also red. One in Mr. 

 W. H. B. Fletcher's collection is of a most delicate pale 

 umbreous with darker nervures and a faint second line; in 

 the late Mr. F. Bond's collection is one of a dull yellow- 

 brown with a very dark distinct central transverse stripe ; 

 and every possible intermediate shade seems to exist.

 in July, August, or even the beginning of September.
