Victoria, Tex. In this connection it has been observed that in the 

 laboratory at night adults of this species stop feeding, become rest- 

 less, and fly about in the breeding cage when an electric lamp is turned 

 on in the room. 



On cotton the 

 writer has taken 

 a specimen of 

 Nezara viridula 

 on a boll at Cam- 

 eron, La., and 

 one at Johnsons 

 Bayou, La., both 

 on October 10, 

 1904, and has 

 taken a fourth- 

 instar nymph at 

 Calvert, Tex., 

 August 27, 1903, 

 and a fifth-instar 

 nymph at Victo- 

 ria, Tex., No- 

 vember 10, 1904. 

 Mr. F. C. Pratt 

 found adults of 

 the species com- 

 mon on turnip at 

 New Braunf els, 

 Tex., on October 

 27, 1905. 



Of 3 9 specimens 

 collected by Mr. 

 Hooker at Quin- 

 cy, Fla., in stages 

 susceptible to 

 parasitism by 

 Tachinids, in 

 only one instance 

 was a Tachinid 

 egg found at- 

 tached to a bug. 



This bug was in the fifth nymphal instar and became adult 4 days after 

 the egg was first observed and died 10 days later, but upon dissection 

 no evidence of the presence of an internal parasite could be found.
