SUMMARY. H.flava L., which now appears to be the species definitely associated with injury to the developing fruits of the plum, is shown to be generally distributed over England and likely to be of economic importance where plums and damsons are grown extensively. The adults are described and the chief points of difference between H. flava and other British Hoplocampids are mentioned. The egg is described and figured and a full description of the larva and its various instars is given. The incubation period and larval development are discussed. The writers are indebted to Mr F. R. Petherbridge, M.A., of the School of Agriculture, Cambridge, for consultation from time to time and for his keen interest in the progress of the investigations.
