wings, arranged as shown in the illustration. The body is slate- 
brown, thinly covered with gray hairs. The under side of the wings 
is much lighter than the upper being light yellowish-brown in 
irregular bars on a white ground. 
There is, perhaps, greater variety both in regard to shape and col¬ 
oring to be found among the different species of the genus Eudamus 
than in any of the other genera of the family. Many of our native 
species are comparatively large, measuring from one and one-half to 
two or more inches across the expanded wings. In this genera the 
antennae are bent into an acutely pointed hook. One of the largest, 
Eudamus proteus. 
and also one of the most attractive, of our native species is Eudamus 
proteus. This insect is two inches or more in expanse, the lower pair 
of wings being prolonged into tails somewhat resembling the 
Papilios. The upper wings are dark brown, with a number of light 
yellowish, translucent spots arranged in two vague rows on the outer 
half of the wing. 
The lower wings are also brown, covered on the inner half next 
the body with metallic-green hairs which, when the insect is alive 
and moving about in the sunshine, flash brilliant green. The outer 
edges of both sets of wings are fringed with yellowish-brown, inter¬ 
rupted with black dots. The body is dark brown, clothed with green 
hairs. The under side of the insect is brown, mottled with darker 
brown. The yellowish spots are seen from below, but are less sharply
