Also known as the Cotton-plant louse, is a great nuisance to the planters, especially when the plants are very small, as then they are more liable to succumb to the attacks of these insects, as by sucking out the sap they distort the stems, and in fact frequently kill the plants before they have attained sufficient maturity and strength to withstand their repeated attacks.

In this age the animals and plants begin to resemble existing species. The age is characterized mainly by the preponderance of reptiles, many of which were very large, as, for example, the <em>plesiosaurus</em>, an animal with a long, snake-like neck and a huge body, or the <em>ichthyosaurus</em>, with a head like a crocodile and short neck and large body. Both of these animals were furnished with fin-like paddles, and lived in water.
