Description. % 



The Adult. — This insect belongs 

 to a group which is known under the 

 general head of flea beetles. The 

 insects of this group are readily dis- 

 tinguished by their small size and 

 their strong hind legs, which give 

 them great power for leading, hence 

 the name, "flea beetle." The adult 

 Tobacco Flea Beetle (Fig. 18) is a 

 small, yellowish-brown insect with a 

 more or less extensive band of darker 

 brown across the middle of its wing 

 covers. It measures about 1-20 of 

 an inch in length. 



The Egg. — The egg, according to 

 Chittenden, is about twice as long 

 as wide, measuring about 1-50 of an 

 inch in length and about 1-100 of 

 an inch in breadth. Grayish in 

 color, with just a faint tinge of 

 yellow.
