INSECTS INJURIOUS TO VEGETABLES 



larva is whitish-yellow with a pale brown head and thoracic 

 shield, the latter inconspicuous. This is a comparatively new 

 importation from the Old World and it is as yet unknown in the 

 United States, but it will probably in time invade our Northern 

 States, and pea-growers should be warned against it. The 

 remedy which gives best results is early planting of the earliest 

 ripening varieties. 



The Bean Leaf-roller (Eiidanuis protcus Linn.). — This species 

 is injurious in the Gulf States to beans, cowpea and cultivated

"beggarweed." It is the caterpillar of a butterfly called the 

 swallow-tailed skipper. The ground color of the caterpillar is 

 yellowish, its head being darker and marked with two orange 

 spots near the mandibles. The head is prominent and separated 

 from the body by the narrow neck, a character which will dis- 

 tinguish it from any other common caterpillar on garden crops 

 (fig. 67).
