We have figured this insect as characteristic of a 
pretty extensive group of butterflies inhabiting South 
America, distinguished by a peculiar outline, and a 
certain similarity of design in the markings. The 
space between the tips of the anterior wings always 
exceeds by more than one half the space between the 
anterior edge of these wings and the hinder margin 
of the posterior pair ; that is to say, the width of 
the insect, with its wings expanded, is more, than 
double its length. The ground colour of the wings 
is generally deep black, with one or two insulated 
patches of some light colour on the disk of the 
anterior pair, and a large blood-red patch in the 
middle of the hinder wings ; the latter deeply den- 
tated on the margin, but without a tail. In P. 
JEneas the upper wings expand about three inches 
and a quarter : they are velvet-black, becoming 
lighter towards the apex, with a pretty large green 
spot, of a somewhat quadrangular shape, towards 
the interior border, surmounted by three smaller
