proved successful, death occurring nine to thirteen days after infection. 

 It is therefore intended to continue this work on a larger scale and to 

 record the results later. 



In conclusion my thanks are due to Mr F. V. Theobald for encouraging 

 me to undertake this research, and to Dr R. Stewart MacDougall for 

 valuable help and advice in its prosecution and for the reading of this 

 paper. I am also indebted to Mr H. Britten for identifying the weevils 

 for me, to Miss L. H. Huie for much valuable advice in technique and 

 other matters, to Mr P. F. Kendall for assistance in carrying out parallel 

 breeding experiments at Wye, and to Dr W. Ritchie for valuable hints 

 in making preparation of my dissections. 



As I am at present engaged in the investigation of the life-history 

 and habits of Sitones puncticollis, flavescens, hispidulus, humeralis, sulci- 

 frons, and crinitus, I should be extremely grateful if any interested in 

 the subject would forward me specimens of any of these species found 

 injuring leguminous crops, together with full particulars.
