LEPIDOPTERA. 175 



gular undulating motion peculiar to the feline 

 race, and noticeable even in the domestic Cat. I 

 find myself making this comparison without any 

 reference to one of the popular names of this insect 

 — the Great Tiger Hawk-moth — a name given in 

 consequence of the black stripes which mark the 

 tawny body of the perfect insect. 



After making my drawing, I took the mea- 

 sures which I thought most likely to insure the 

 successful metamorphosis of this remarkable crea- 

 ture to its pupa and winged states. 



I had heard that many attempts to rear a perfect 

 Moth from the Caterpillar of this species had failed, 

 the insect almost invariably perishing in the pupa 

 or chrysalis stage. Thinking that this might be 

 caused by the over dryness of the earth in which it 

 was placed, or, at all events, from its not retaining 



o 



the same constantly equal state of moisture that 

 would exist at the depth to which the Caterpillar 

 generally burrows, I took the following precautions : 

 A large flower-pot being selected, I stopped up tbe 

 hole with a cork, taking care to pass a quill, open 

 at both ends, through the cork, to serve as an 

 escape-pipe for superfluous wet, and yet not being 

 large enough to allow of the escape of the 

 Caterpillar.
