(52 [August, 
No further change took place in the markings of the pupa till 
about the middle of the month of March, when the brown abdominal 
patch re-appeared, and showed through the ventral surface ; the next 
day two short projections were observed at the posterior end of 
the abdomen ; these proved to be the ends of the wing-cases, which 
I had previously noticed were gradually retiring over the sides of the 
pupa ; the following day the eyes, which had been slowly deepening in 
colour, turned quite black, and the ventral surface of the pupa became 
partially split open, and down the centre of the portion so split open, 
several faint dusky spots were dimly traceable (these spots, I believe, 
were caused by the thoracic, and a portion of the abdominal ganglia, 
faintly shadowing through the body of the pupa). 
The next day a rather thick dark streak appeared down the centre 
of the thorax, and two days later, this streak was crowned by a little 
circular dusky spot ; the brown patch on the dorsal surface of the 
abdomen shrank lower down, and the feet of the future imago slowly 
began to separate themselves from the pupa ; the following day the 
dusky streak, which had appeared three days previously down the 
centre of the thorax, became reduced to a mere line, and instead of 
being crowned, as before, by a little circular dusky spot, the place of 
the latter was occupied by two short parallel lines ; a small cluster of 
three dusky spots also appeared on the centre of the abdomen. 
On the 2nd of March the thorax became free of all markings, 
and one of three dusky spots on the back of the abdomen disappeared, 
and the other two soon followed it, and the light brown abdominal 
patch (wnich had become reduced to a mere speck) had almost dis- 
appeared, having shrunk down to the extreme end of the abdomen, 
from which it ultimately retired altogether. 
Seven days later a dark spot was observable on each side of the 
base of the thorax ; these spots gradually enlarging, finally became 
blended into one dark coloured blotch, which slowly spread over the 
thorax, head, and wing-cases, turning them shining black ; after which, 
the deeper colour spread to the abdomen, though the latter only became 
slightly discoloui'ed in comparison with the head, thorax, and wing- 
cases, on which the usual markings of the imago gradually made their 
appearance. 
On the 3rd of April the pupa skin, splitting at the back of the 
head, enabled the imago to effect its escape by leaving the skin behind 
it on the leaf; it hurried up the side of the cage, and unfolded its 
wings to dry.
