HIALOPHORA PROMETHEA. 135 
direction nearly parallel to their external edge ; near 
the tip of each of the anterior wings there is a 
black spot surmounted by a blue crescent : hinder 
wings with a row of spots within the narrow black 
line skirting the outer border. The markings on 
the under side, in this sex, are similar to those just 
described; but the colour is paler, and the most 
considerable differences consist of a small transverse 
w^hitish spot in the centre of each wing, and in the 
grey waved line near the middle of the hinder 
wings being continued round, except on the abdo- 
minal edge. 
The female presents important differences. The 
body is reddish-brown ; on the upper side the half 
of the wings next the body is dark red, with a pretty 
large angular light-coloured spot towards the centre, 
and in the upper pair, a light-coloured bar runs 
out from the base, and after proceeding for some 
distance, bends towards the anterior border ; a little 
beyond the middle, a light-coloured waved band 
runs across all the wings, bounded by dark cho- 
colate on its inner edge ; tips of the anterior wings 
with a black spot partly encircled with blue ; the 
margin itself dark buff, with a narrow zigzag black 
line running through it ; within this, on the under 
wdngs, is a row of irregular red spots. On the under 
side the body is streaked with white ; the colours 
pale ; the angular band wanting at the base of the 
anterior wings, and the light-coloured portions ap- 
pearing as if sprinkled with fine grey powder. 
The following is Mr. Peale's account of the habits
