There are two things in Molina’s description which 
render the identification of his species with P. bias 
extremely doubtful; the first is, his speaking of it as 
‘** Papilio Nymphalis”’; and the second, his mention of 
blue spots upon the upper surface of the wings. I know 
of no Chilian butterfly to which his description will 
apply. 
The following is a description of the transformations 
of P. bias :— 
** Larva.—Dark brown, studded with short orange-yellow 
spines. Head black and shiny ; second segment with a 
hard black plate on the back, and on the front part, 
immediately behind the head, a fleshy protuberance of a 
yellow colour, which is erected when the larva is annoyed, 
and then resembles in shape the letter Vv; on each side 
of the front of the second segment there is a fleshy 
horn, yellow at the base and black at the tip, slightly 
curved forwards; the rest of the body is of a deep 
madder-brown colour, each segment having a_ short 
fleshy spine on each side above the spiracles, and one 
on each side of the back ; these spines are orange-yellow, 
with the extreme points black; the second, third, and 
fourth segments have each a dull orange spot above the 
prolegs ; prolegs and claspers black.
