SATURNIA PAVONIA MINOR. (Frontispiece.) The Emperor 

 Moth. This beautiful species sometimes attains to three 

 inches in width : the colour is greyish brown, faintly tinged 

 with purple ; the hinder margin of all the wings has a band 

 of pale brown, with two transverse bands of brown and 

 purple on each wing, the hinder band very much waved ; 

 the centre of each is also ornamented with a large ocellus, 

 placed on a light ground, consisting of a black pupil with 

 a yellow or grey iris, and partly surrounded by a light-blue 

 crescent ; in the apex of the anterior wings there is a patch 

 of purple and a black or whitish mark. The caterpillar is 

 of a lovely green, and has a black band on each segment, 

 adorned with pink tubercles, bearing a whorl of six hairs 

 diverging like a star. Latreille mentions a manufactory 

 established in Germany, in which the silk of which the 

 cocoon consists is used ; the singular form of this cocoon 

 was described in March.
