 larva, (Fig. 65, .c) of 

 the Chinch-bug and 

 (Fig. 66, a) of the 

 Harelequin Cabbage- 

 bug, do not differ 

 very materially in 

 form in the pupa state 

 (Fig. 65, #, and 66, 6), except that they are provided with 

 wing-pads, that is, cushion-like swellings, in which the undevel-

oped wings are enclosed; they move about and take food in the 

 same way as in the larva state. 



The pupa? of those insects, however, which were worm-like 

 Fig. 68 when they issue from the egg, are incapable 



of moving about and taking food, their legs 

 and other appendages being folded up and 

 encased in a sheath; such as the pupa (Fig-

In some pupa3 such as those of the Beetles, Bees, Wasps, 

 and many Two-winged Flies the antenna?, wings, and legs are
