86 LEPIDOPTL'RA. 



moth, with orange brown wings, variegated with many 

 curved black and white streaks, once not uncommon in 

 Kent, is now very rare there. It has, however, been 

 taken in hirge numbers in the Rannoch woods, near 

 Perth. I must not omit to mention the Emperor 

 moth {Saturn ia Pawnia minor), with its four e3^e-like 

 spots in a yellow ring surrounded by a black one, and 

 wings prettily variegated with brown, red, grey, and 

 orange. It appears in April. 



Caterpillar of the Tiger-Moth, or Woolly Bear. 



The PsycJiidw family belongs also to the Bombycina 

 group. In it the females are even more helpless crea- 

 tures than those of the Vapourers ; for not only are 

 they destitute of wings, they have neither legs nor an- 

 tennae. The female is a mere bag of eggs, never quitting 

 the covering in which it was bred. The larva constructs 

 a moveable case in which it lives and undergoes its 

 metamorphosis. This house-building peculiarity will 

 remind us of the Caddis Worm insects I have already 

 spoken of. These larvae must be looked for in spring 

 and summer. 



The third group, that of the Noctuinw, contains about 

 300 British species, As their name implies, these moths 

 fly, as a rule, by night, but there are day-flying species.
