cause the coverings of some of them have spots of a

present day as synonymous with pupa, and this state of 
the Insect is called the Chrysalid state. 
405. The changes which take place in the pupa state 
are very great, even radical ones. There is commonly 
no resemblance between the Larva and its Imago. There 
may be great beauty in the Imago, and none in the Lar- 
va, and sometimes the reverse is the case. Then, as to 
form and general structure, the contrast is of the most 
marked character. In the Larva state it was a slow,

And the change is as great internally as it is externally. 
Its stomach even is changed, for its mode of getting a
