antly ciliated ; abdomen stouter ; fore wings broader, with 

 rounded costa ; otherwise similar. 



Underside pale brown ; more yellowish round the hind 

 margins, with a faintly reddish submarginal stripe ; all the 

 wings with a rust-red central lunule ; body golden-brown ; 

 legs red-brown. 



Variation in this species is distinctly local and climatal. 

 The form described is that of the southern half of England. 

 In the Midlands darker specimens, having less of the yellow 

 and rusty colouring, occur in every shade of variation ; while 

 in Scotland and Ireland, and in the North and North- West of 

 England, the form usually found is that named 'pcrfusca, in 

 which the red and yellow colouring are much restricted or 

 obliterated, the fore wings becoming in some instances 

 entirely dark purple-brown except a faintly pale blotch at 

 the base. Usually, however, some traces of the reddish or 

 yellowish colour of the transverse lines is visible, with the 

 rusty spot at the anal angle. This northern form has also a 

 pale aberration in which the fore wings are of a pale semi- 

 transparent purplish. Mr C. S. Gregson has one of a creamy- 

 white with faintly yellowish markings. Aberrations also 

 occur in the typical southern race, the rusty colouring being 

 much developed. Mr. F. J. Hanbury has one, obtained in 

 Norfolk, of which the fore wings are almost totally suffused 

 with rust-red. A specimen from the New Forest, in Mr. 

 W. H. B. Fletcher's collection, is of a pale chestnut-brown, 

 without dark clouding except in the central space between 

 the two lines ; and another, of a fuller brown, has the central 

 space bluish grey. 



On the wing in May and June, and, as a partial second 

 generation, in July or August. So far as I can ascertain 

 only single-brooded in the North and West, occurring in 

 June and July. 



Larva stout, but tapering anteriorly from the sixth 

 segment, and sloping back from the apex of the twelfth.
