SATYRIDAE 
Female .—This is usually larger, and the colouring is rather 
paler ; it is without the cilia in the discoidal cell; the bands 
inclining to orange. The ocellated spots are larger ; there 
are generally five instead of four on the under side. The 
hind wing is more distinctly banded, the sub-marginal band 
being ochreous instead of grey. 
Life of Imago. Probably not exceeding twenty-one days. 
Aberration. The spots vary greatly in size and number. 
Sometimes they are greatly enlarged, at others they are 
reduced to two, while in some specimens only fulvous rings 
remain. In rare cases the spots and bands on the hind wing 
are absent. The colouring of the bands varies in depth. 
Occasionally examples approaching albinism occur.

Haunts and Distribution. Although less abundant than 
formerly, and in certain localities it has disappeared, it is still 
one of our common butterflies and in certain places it often 
occurs in profusion. It is to be found generally distributed 
over the southern half of England. It is most frequent on 
chalky ground, but is also common on clay soils. Yorkshire 
is the northern limit for this beautiful butterfly, which is 
unknown in Scotland and Ireland. Its range abroad extends 
through Central and Southern Europe and Asia Minor. 
The favourite haunts of the Marbled White are rough 
uncultivated grassy slopes, hill-sides, meadows and sometimes 
rough openings and outskirts of woods. It is usually very 
locally distributed, is often confined to a certain field in 
abundance and hardly found elsewhere in the neighbourhood ; 
at other times it ranges over a large extent of ground in a 
certain district. 
The Marbled White has a rather slow, flapping flight, and 
when on the wing cannot be mistaken for any other British 
species owing to its greyish, speckled appearance due to its
