The Colours of Animals. 



In the next stage the larva has a solid corneous 

 envelope and an oval shape, and, in its colour, con- 

 sistency, and immobility, resembles the chrysalis of 

 a fly. The time passed in this condition varies 

 much. When it has elapsed, the animal moults 

 again, again changes its form ; after this, it be- 

 comes a pupa, without any remarkable peculiarities. 

 Finally, after these wonderful changes and adven- 

 tures, in the month of August the perfect beetle 

 makes its appearance.
