PALE CLOUDED YELLOW 
BUTTERFLY. 
It is singular, that this Butterfiy, though 
known to be a native of England, where it is 
occasionally found, has escaped the notice of 
Linnaeus ; in wliose system, the Clouded Yel- 
low, of which Pale Clouded Yellow seems 
to us merely a variety, is the liyalc, Danai. 
Some natui-aiis&s call this last the SaiFron But- 
terfly. /. : 
Neither the Caterpillar, nor Chrysalis, of 
either of these Butterflies, is known to any of 
our aurelians ; and very few, indeed, of the 
most diligent colle(3:ors, have ever caught the 
Pale Clouded Yellow. The Clouded Yellow, 
though scarce, is by no means so rare. 
They are about the same size ; the wings of 
each expanding two inches and a quarter: and 
their general form, as w^ell as the shapes of the 
particular spots and markings, are extremely 
similar. But the principal colour has the distinc- 
tion denoted by their names: the Clouded Yel- 
low
