THE EMPEROR MOTH. 95 
punctated dots, from whence emanate short fasciculi 
of very fine hairs ; along each side is a longitudinal 
yellow line; the belly is rusty brown, and the 
feet are black. They are subject to considerable 
variety of appearance, as they progress towards 
maturity. When young, they are yellowish; the 
tubercles black, with a stripe of the same colour 
as the segments of the joints. After this, the 
yellow bands become orange, and the transverse 
black stripes appear interrupted with longitudinal 
bands of pale green. Some are entirely green 
except the tubercles, which are yellow, and a small 
black speck on each joint ; and others are green, 
chequered with black, and marked on the side 
with a row of similar spots. In the winged state, 
however, we find no permanent and characteristic 
distinctions. 
In the earlier state the caterpillars are grega- 
rious. 
The chrysalis is black, and very blunted in shape. 
The conformity and likeness which prevails be- 
tween the male and the female throughout the 
greater part of the animal kingdom, cannot, how- 
ever, in insects he depended on; the difference is 
frequently such as to deceive even the most expert 
entomologists. The difference between the male 
and female Emperor Moth is strikingly obvious; 
the male is smaller than the female, and the 
colours in general darker ; the lower wings also are
