 worm [Protoparce celeus, 

 P. ccu'olina). 



Of all the insects feeding 

 upon tobacco, this oue is the 

 most injurious and conse- 

 quently most generally 

 known. In many sections 

 on account of its damage to 

 that plant it is also known 

 as the Tomato-worm. It 

 may be well to first state, 

 however, that two species 

 of insects are ordinarily in- 

 cluded under this popular 

 name. The IN^orthern To- 

 bacco-worm is the more 

 common form in many of 

 the more northern parts of 

 the tobacco-belt, especially 

 in Connecticut, though it 

 is generally found wherever 

 tobacco is extensively grown 



in the United States. The Fig. 130.— Tobacco-leaves dam-
