“Que portion of the blue near the tip is lost, and on the lower wing 
whe outer part of tne ring round the eye is obscured by the ground 
-colour; by cold the bluish white marks are reduced; white, black, 
-and a few blue scales appear beneath the reddish ground colour 
-and the border—and the inner patch on the fore margin is 
extended towards the shoulder—by still more prolonged cold, six 
weeks, there appears in some cases a black spot on the inner margin 
- corresponding to that in the tortoiseshell, the middle part of the 
-eye acquires black scales corresponding to the end patch in the 
tortoiseshell. In some instances the eye of the hind wing is 
- almost obliterated. 
In the Camberwell Beauty, with 48 hours’ heat, the blue spots 
are greatly reduced in the fore wing, and the yellow border reaches 
‘the blue spots. With 60 hours’ heat, the blue spots are reduced 
to half the size, and tinged wi h violet, tne ground colour becomes 
darker, and the yellow border becomes so much darker that but 
few yellow scales are visible, the projecting points of the border 
are not so prominent. With cold the ground colour becomes 
lighter, spots appear like the two centre spots of the tortoiseshell, 
the blue spots of the fore wing become much enlarged and ringed 
with black. With more prolonged cold, the blue increases, the 
_yellow border narrows, and in a few cases the blue spots of the 
hind wing not only reach the border, but are continued into it as 
acute projections. With 44 days’ cold, the border becomes still 
narrower, and is much mixed with black scales, the blue intrudes 
still more into the border, and the ground cjlour becomes velvety 
black. 
In the tortoiseshell, heat 60 hours, the blue spots on the margin, 
especially of the fore wing, disappear, as also do the black spots 
near the centre; the black patch on the hind margin is much 
smaller, sometimes nearly disappears. With cold, blue spots in the 
border become larger and well defined; in several specimens a 
black transverse shade passes from hind patch to front, looking as 
if nearly half the wing was blackened up to the shoulders. With 
-42 days’ cold the beautiful blue spots are overpowered by black, 
like the polar varie'y. 
The red admiral, heat 72 hours, blue of the fore wing becomes 
reduced to two small spots near the tip, red band widens in both 
directions, abundant reddish shading between the red band and the 
shoulder. The white spots all reduced in size, sometimes the fifth 
dissappears. Many examples, too, have red scales between 2nd 
-and 3ri white spots. 
With cold, the white spots are much enlarged, the red band is 
narrowed and divided by two black shades abont the middle into 
three portions; the lower portion of band is also cut off. In ex-
