to feed. While the amount of fruit that developed on the check 

 plants was not as great as it would have been under natural field 

 conditions, the effect of the feeding of the n} T mphs was apparent 

 when plants receiving the two treatments were compared. (See 



fig. 2.) 



During 1916 an unusual type of injury to cauliflower was reported, 

 from Breaux Bridge in St. Martin Parish and from Terrebonne 

 Parish, La. This was apparently due to the feeding of both adults 

 and nymphs of the Southern green plant-bug. They were numerous

at and about the point where the leaf stems are attached to the main 

 stalk of the plant. The stems became discolored and the leaves 

 dropped prematurely. 



DESCRIPTION OF STAGES. 



THE ADULT. 



The adult (fig. 3) when viewed from above has the characteristic 

 form of the family Pentatomidas, which may be described as shield- 

 shaped. The dorsal surface of the body is slightly, and the ventral 

 surface strongly, convex. 



In living specimens the body as well as parts of the appendages are 

 usually light green, the dorsal surface being somewhat darker than 

 is the ventral surface. Exceptions to this may be found in the case 

 of adults collected during the cooler months of the year. Such indi- 

 viduals are darker in color, perhaps because of the lower temperatures
