FOREWORD. 
—_—#—— 
Tuts bulletin aims to give as complete information as 
possible about a very serious insect pest. As the pest isa 
new one, and as practically nothing has been published 
with regard to it, I have thought it wise to give a detailed 
scientific description of the insect and a full account of its 
life-history, in addition to the discussion of what are com- 
~monly but erroneously considered more practical matters. 
A popular account is being prepared for issue as a Kana- 
rese bulletin. 
The facts, as here given, are the results of observations 
and experiments extending over about two years. In this 
connection, I wish to express my appreciation of the effi- 
clent service rendered by B. C. Shantappa, formerly Field- 
man but now Agricultural Inspector in this Department, 
in the carrying out of practical measures planned by me. 
The coloured plates are from paintings made by 
M. Ranganayakalu, Artist of this Department. All photo- 
graphs as well as the original drawings for most of the other 
figures were made by the author. 
In conclusion, | wish to express my thanks to 
Mr. C. H. Yates, Superintendent, Government Press, for 
the great care he has taken in the printing of text and 
plates.
