The eggs of insects are usually 

 . of a globular form, such as the 

 eggs (Figs. 24 and 25) of some 

 species of Butterflies; but some are ft 

 flattened, such as those (Fig. 26) If 

 of the Katydids, while others are |j|| 

 elongated, as those (Fig. 27) of thellj 

 Tree-crickets; still others, as those w 

 (Fig. 28) of the Tortoise-beetles 

 are furnished with spines. 



The surface of some insects' eggs 



are perfectly smooth (Fig. 26); others are ribbed 

 (Fig. 24), and still others are covered with a net- 

 work of raised lines (Fig. 25). 



Insects deposit their eggs in a great variety of 

 situations, but always where the caterpillar or larva, as soon 

 as hatched, may find an abundance of food within easy reach.
