MISS CYNTHIA LONGFIELD, British Museum (Nat. Hist.), Cromwell Road, London, S.W.7, writes: "As I shall be revising for publication, in the very near future, the records on distribution of all the British dragonflies, I shall be most grateful if all collectors, who have not done so already, will send me their lists of localities, including approximate status, of dragonflies identified up to the end of 1944. Observations on habitats, definite proof of breeding and methods of oviposition will be most valuable. All help will be gratefully acknowledged."
