50 HAWK-MOTHS. 
THE PURBLIND SPHINX. 
(Paonias myops S. & A.). 
This is another moth closely allied to the preceding one. 
It is somewhat smaller, measuring, when the wings are ex- 
panded, about two and a half inches across. It is very 
handsome, and much brighter than the excecatus (Fig. 54, 
Plate VIII). It has a chocolate-brown head and thorax, 
with a purplish tinge; the thorax has a tawny-yellow stripe 
down the middle; the abdomen is brown, with dull yellow- 
ish spots. The fore-wings are chocolate-brown, with black 
bands and patches. The hind-wings are dull yellow, with 
the outer half chocolate-brown; an eye-like spot is found 
towards the inner margin; it is black with a large pale blue 
center. When at rest this moth is also thoroughly well 
protected by its position and color, which unite to give it 
the appearance of a dead leaf. 
The caterpillar of this moth occurs on the cherry tree, 
but is uncommon. Since the electric lights have been intro- 
duced the moths are seen more frequently. The caterpillar 
is found during August; it is a large, cylindrical green 
worm, about two inches long, with a curved horn at the 
end of the body. Its head is bluish-green, with a bright 
yellow line on the sides; the body is green, with a row of 
reddish-brown spots on each side of the back, and another 
similar row down near the breathing pores. Along each side 
there are six oblique, bright yellow bands, and two short 
yellow lines on the anterior segments. The horn is green, 
tinted with yellow at the sides. When full grown the cater- 
pillar enters the earth, where it changes to a dark brown 
pupa, which remains in the ground until the following June 
or July, when the perfect insect escapes. 
The caterpillar is not common enough to cause great 
injury to cherry trees, and as it can be readily detected by 
its work it is easily kept in check.
