ICEBYA PUBCHASI. 71 



Bairstow, of Port Elizabeth, President of the East 

 Province Naturalists' Society, wrote me: "The 

 Australian Bug seems to be extending operations in 

 Bloemfontein and higher up country." This observation, 

 together with the foregoing, shows a spread over a length 

 of 680 miles that is, from Cape Town to Bloemfontein 

 during the fourteen years which then had passed since 

 first observation of the pest in the Colony, and a glance 

 at the map of South Africa will show the vast extent of 

 area of the Eastern division in which the pest had then 

 naturalised itself. Where it came from does not appear 

 to be proved, but there does not appear room for doubt 

 that the attack was set on foot by imported specimens, 

 and that it rapidly became naturalised. 



The Bug appears to attack such a great variety of 

 trees, bushes, &c., that it may be well described as a 

 general pest. Oranges, or plants of the Citrus tribe, 

 are especially infested by it. Vine and fig are also 

 mentioned specially as injured by it, and more generally 

 deciduous fruit trees, ornamental shrubs, and garden 

 plants, the list ranging down to strawberry plants.
