THE C/RULEAN BUTTERFLY. 
Papilio Cerulea. 
PLATE XXXVIII. 
Papilio Argus, Harris’ Aurelian, p. 75, pl. 39, fig. i—Linn. 
Syst. Nat. p. 789.—Polyommatus Argus, Latreille. 
Tue wings of the Cerulean Butterfly are of a 
deep azure blue, as also the body ; the under wings 
have a very broad band of dull crimson at their 
lower margin, which reaches nearly to their centre ; 
this band is spotted with circular and triangular 
black dots ; the whole posterior margins of both 
wings are surrounded by a white edge. 
The female differs considerably from the male, 
the upper side being of a dark brown colour. 
The under side of the wings are handsomely 
bordered with eye-like spots ; the other parts of the 
wings are of an ash colour, besprinkled all over 
with small ocellated spots, or circles. 
This butterfly emerges from its chrysalis about 
the beginning of June. It is found in several parts 
of Britain, but not in great abundance.
