Green bug has always been regarded as a most 

 serious enemy of coffee. According to Green/ who first 

 described the insect, it was practically responsible for the 

 final abandonment of coffee in Ceylon. Since its appearance 

 in Ceylon in 1882, it has been recorded from almost 

 all the coffee-growing countries of the world. Green 

 does not give the distribution of the pest, though he refers 

 to a new variety described by Mr. Newstead, from Lagos 

 in West Africa. Mrs. Fernald^ recorded it from Ceylon, 

 Brazil and Mauritius. From scattered references to the 

 pest in the Eeview of Applied Entomology, it appears 

 to exist either as a pest of lime or coffee in Samoa, 

 East Africa, Seychelles, Virgin Islands, Barabados, 

 Guadalonpc Java, Uganda, South Africa, Hawaii and 

 Mauritius in addition to India and Ceylon. 



The insect was not recorded from Ceylon before
