SUMMARY. Observations on the biology of Hoplocampa flava L. are given. Reasons are given for stating that all records of plum sawfly damage in England referred to H. fulvicornis should be referred to H. flava L. Observations are given showing the variation in intensity of attack during 1925–32. Control experiments with the object of killing the larvae were promising in 1929, but yielded no control in 1932. The authors are indebted to Dr H. W. Miles and Mr H. Kingston, who were associated with us in the above observations in 1926, and to Messrs M. H. Ivatt and G. H. Cannon, on whose plantations the observations were made.
