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 j 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 be 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
