NOTONECTA. 101 



elongated eggs, which she generally places on 

 the stems and leaves of aquatic plants. In the 

 beginning of spring the little ones break their 

 shell, and directly swim upon their back as well 

 as their mother. The larvae resemble the perfect 

 insect, except in the want of wings. They have 

 the same habits, living in the same manner, 

 and waging continual war with the lesser in- 

 sects. In about two months they take upon 

 them the chrysalis state, and in a short time 

 after, undergo their last change, and appear with 

 their wings and semi-coriaceous wing-cases.
