is pale olive, verging in some places into gray; the markings 
consist of patches and stripes of dark, rich velvety olive, 
sometimes almost black (Fig. 414). Near the inner margins 
of both pairs of wings the lighter color shades out into pale 
yellow, which is tinged in places with delicate rose-color. 
These markings show a harmony of contrasting shades 
rarely equalled elsewhere by nature or art. The larva is 
one of the Hog-caterpillars. It feeds upon the leaves of 
Virginia-creeper. When young it is pinkish in color, and 
has a long pinkish caudal horn; as it matures it changes to 
a reddish brown, and the horn shoitens and curls up like 
a dog’s tail and finally disappears, leaving an eye-like tuber¬ 
cle. The caterpillar has on each side six cream-colored oval 
spots, enveloping the spiracles. 
The White-lined Sphinx, Deileplnla lineata (Dei-Ieph'i-la 
lin-e-a'ta).—This moth can be easily recognized by Figure 
415. Its body and fore wings are olive-brown; there are 
three parallel white stripes along each side of the thorax; 
the outer one of these extends forward over the eyes to the 
base of the palpi; on the fore wings there is a buff stripe 
extending from near the base of the inner margin to the 
apex, and veins III S to IX are lined with white; the hind
