CONCLUSION. 



Sufficient has been said to indicate the extreme gravity of the 

 outbreak to the cultivators of sugar cane in this country and the lines 

 along which it is suggested that the control might be effected. 



Finally, I must express my thanks to Mr. Laing, of the Imperial 

 Bureau of Entomology, for very kindly identifying the insect as 

 Pseiidococcus sacchari CKLL,., and to M. Henri Naus Bey and the 

 managers and staffs of the Sugar Company for their unfailing courtesy 

 and kindness in affording me every possible facility for the study of 

 the problem.
