 [Received 18th July 1922.] 



The Rhynchota of New Zealand are far from being well known, 

 although this group is a very important one from the economic aspect. 

 The species are dealt with under 26 families, and it is hoped that the

The various causes of injury to plants, and the general methods for 

 their prevention and control are here outlined, and formulae for the 

 use of insecticides and fungicides are given. Thorough preparation 

 and cultivation are of great importance in the prevention of diseases, 

 and the greatest advances to be made in their control are in the 

 development of resistant varieties of crops by hybridisation and 

 selection.
