quently, it ma}- he well to explain tliein here. On taking 

 an insect in tlie hand it will be seen tliat the body is divided 

 into tln"ee parts, the head bearing the eyes, feelers, mouth 

 parts, etc., the thorax, which is nsually mnch larger and to 

 which the wings and legs are attached, and lastly, a longer 

 and larger portion, the abdomen, and these tliree terms 

 will be often nsed in the following pages. The head and 

 thorax are sometiines very closely united so that they do 

 not at first seem distinct, but there is usually no trouble in 

 distinguishing them, and the abdomen is rarely so closely 

 united to the thorax tliat its line of separation cannot be 

 seen. Insects are found in three different states. When 

 an insect comes from the egg it is nsually more or less 

 worm-like in appearance, and is then called a. larva, such 

 as any caterpillar, the army worm, various grubs, etc. After 

 living for sometime in this state, eating enormously and 

 growing very rapidly insects pass into the next, the chrysalis, 

 or pupa state, a state of inactivity, and from the chrysalis 

 they come forth f ully gi'own and developed forins, the adult 

 or imago condition. Sometimes an insect does not change 

 much in form and appearance as it passes from one state to 

 another. This is true of locusts, while others, like the but- 

 terflies, are wholly different in appearance in each of the 

 three states. 



As the space at my disposal is necessarily limited, I am. 

 unable to do much more than make a beo-innin'i; of the 



CD o 



work of describing the injurious insects of this State. Al- 

 most every species of plant and tree in the State is attacked 

 by one or more distinct species of insects. While I fully 

 believe that complete accounts of all these, with suggestions
