 The appearance of the

 companion pupa. All the 

 parts of the perfect insect 

 can be distinctly traced, 

 if the pupa is sufficiently 

 matured. 



By gently using a fine needle, the wings, an- 

 tennae, and legs, can be separated from the side of 

 the body, and made to exhibit somewhat of their
