62 THE ENTOMOLOGIST. 
wings are fading from green to a creamy colour, and the brown 
linear markings on the wing-cases seem more intense, but this 
intensity is probably more apparent than real, owing to the 
lighter ground-colour of the wings; the dark central thoracic line 
also appears to have gained in intensity. The green colour of the 
abdomen shows little signs of change. 
October 1st, forenoon: The eyes are of a more pronounced 
brown ; the mouth-parts are much darker than they were the 
previous day; the wings are now of a creamy colour, and have 
quite lost any trace of green. A dark shading appears on the 
thorax towards the head, and the dark line down the centre of 
the thorax is much more pronounced; a change also appears in 
the abdomen, which is now of a greenish-white colour. 
October 2nd, midday: The wings are now of a buff colour, 
tending towards a faint brown over their central area; the dark 
shading has now fully occupied the thorax, and is extending to 
the abdomen. The dark line down the centre of dorsal surface of 
abdomen is much more intense, being almost black on the fourth, 
fifth and sixth abdominal segments. The appearance of the pupa 
is now quite changed from that of three days ago: the only 
indication of green (a faint greenish-yellow) that can now be 
observed is on the abdomen, being most pronounced on the sides, 
while the deepest shade of brown is in the region occupied by the 
mouth-parts, legs, ete. 
October 2nd, midnight: The wings are of a decided brown 
colour, deep enough to obscure the linear markings on the wing- 
eases, the central area of the wings being much darker than the 
margins. The dark shading on the thorax is now so intense that 
the central dark line is almost unnoticeable. The antenne attract 
attention owing to their being slightly lighter than the colour of 
the surrounding parts; the abdomen shows little further change. 
October 3rd, 10 a.m.: The wings are now of a very dark 
brown colour; the fulvous area on the fore wings shows very 
clearly through the pupal casing, and the black dots within this 
area can easily be made out. The dark line down the centre of 
the thorax is still discernible, and along this line rupture takes 
place during dehiscence. Except in the abdomen, which is the 
last part of the pupa to undergo change, there is little further 
difference in the appearance of the pupa. Change in the abdomen 
is taking place from two centres, and consists of the dark 
shading before mentioned; one of these centres is the dark line 
down the centre of the dorsal surface, and the other is a similar 
dark central line down the ventral surface of the abdomen. 
These lines, which are most pronounced, are gradually increasing 
in area, the dark shading fading off laterally; the abdomen 
therefore shows lightest on the sides, and is here of a drab colour 
with only the faintest suggestion of yellow. 
October 8rd, 2 p.m.: The dark shading has now occupied the
