The tendency towards concentration of the thorax 



seems to be back- 

 ward, or in the direc- 

 tion of the centre 

 of gravity of the 

 body, rather than 

 headward. It has 

 already been seen 

 that the scutellum 

 (Fig. 69, ts-) ex- 

 tends backward in 

 the adnlt, conceal- 

 ing the metathorax, 

 which is distinctly 

 seen in the pupa 

 (Fig. 69, ^"'), bear- 

 ing the second pair 

 of wings (w"). The 



thorax and abdomen of the pupa are more chitinous 



than the same parts of the larva, though the head in 



the specimens examined was not so dark-colored. 



The antennae, sucking-tube, and legs resemble those 



of the adult.
