COLDEN EMPEI.OR. 
All the colours of the Under Side of this 
Butterfly are changeable, according to the po- 
sition in which the insect is placed ; appearing, 
in fact, as if painted with transparent colours 
on a golden ground. 
It measures four inches and three quarters 
over the upper wings ; or, from tip to tip. 
On account of the prodigious difference in 
colour, between the Upper and the Under 
Side of this most beautiful Butterfly, though 
the markings are very exactly the same, we 
have thought it necessary to represent both 
sides in the print annexed, which affords a 
good idea of this inimitably fine insect.
