seen in certain lights. The insects are supplied with long, clubbed 
antennae, a stout thorax furnishing room for the powerful muscles to 
move their strong wings, and a short, small abdomen. They are ex- 
ceedingty active, and fly with great rapidity, although their flight is 
not usually long sustained. The under side of the wings is usually 
adorned with eye-like spots. In some species these are numerous, in 
others there is but one to each side. Several of the most beautiful 
species inhabit Mexico and Central America. 
Apatura clyton. Male. 
Our best known of the four species of this genus inhabiting the 
eastern half of the United States is Apatura clyton. There is a 
good deal of difference in size between the sexes, as will be seen by 
reference to the illustrations. The upper wings of the male are 
light rusty brown on the inner half, the outer half being dark brown. 
Two irregular rows of large rusty yellow spots are located on the 
outer half, the inner row margined on the inner side by a black line. 
A row of tawny spots runs along the outer margin, beginning large 
at the lower angle and growing smaller and finally fading out toward 
the apex of the wing. Two uneven black marks are placed just 
below the upper margin on the inner third. The lower wings al¬ 
most reverse the coloring of the upper pair, and with the exception 
of the concave inner margin, which is yellowish gray, the inner half 
of the wing is reddish brown and the outer half reddish yellow or 
tawny orange. The veins are dark brown, the outer margin brown. 
Six roundish black spots extend in an irregular line from near the 
upper margin across the wing to near the lower angle. The thorax 
and abdomen are greenish brown. The spots and markings of the
