larval stage may last but for a week or two, but in some 

 insects is known to extend over several years. In some 

 insects, as tlie ^losquitoes and Dragon Flies, the life of 

 the larva is passed entirely in the water. 



When the larva has made its full growth it passes into 

 the state of the pupa — (the name for an infant rolled up 

 in bandages after the manner of the ancient Eomans), 

 this is also called clirysalis, from the Grreek word for 

 gold, as some have gold-hke markings. Most insects are 

 in this state perfectly dormant, while a few, as will be 

 noticed further on, remain active. Some in their last 

 moult appear as if swathed in a hard mummy-like case, 

 others make a cocoon of silken threads, like the Silk- 

 worm, in which to assume this state; some make a hol- 

 low chamber in the earth for the same j^urpose; and a 

 number draw together leaves to form a covering to hide 

 them while in the pupa state. 



The insect may remain in the pupa state for a few days 

 or weeks, or it may pass the winter in this dormant con- 

 dition. The methods by which the escape from this 

 imprisonment is made at the proper time, are various 

 and interesting to the observer. In due time it comes 

 forth, and when, as in the case of some moths, it has 

 spread and dried its wings, it seems wonderful that it 

 could have been packed in so small a space. 



The perfect insect which is usually provided with 

 wings, is also called the Imago, the Latin for an appear- 

 ance or an image. 



In the study of insects, it is convenient to bring them 

 together in what are termed Orders, according to their 

 general resemblances. There are seven of these Orders, 

 each of which is subdivided into families, genera, etc. 

 While entomologists differ as to the minor divisions, 

 these Orders are generally followed in uKjdern works. The 

 first, and regarded as the highest Order is
