Insecta. 29 



Select two pages in your notebook that face each other. On 

 the left-hand page make a list of characters common to all the 

 insects you have studied, numbering the points; on the right- 

 hand page write briefly the characters peculiar to each insect. 

 The first list ought to be a very nearly correct definition of an 

 insect, so far as external features are concerned. The second list 

 should serve as a definition of each of the orders of insects. 



All the orders of insects belong to the class Insecta. 



Write now a list, in vertical series, of the orders of insects 

 studied, with the name of the insect representing that order oppo- 

 site it, and include all within a brace opposite the word Insecta.
