This is a facsimile of the original, much sort of and very expensive, 1975 edition, but without any of the original plates. The originals were of very poor definition and considerably better reproduction are presently available. For example the descriptive booklet at £2.50 or the Field Guide by Edwards and Jenner and the most excellent facsimile of Sladen. Dr Alfords work provides an overall and up to date picture of the existing (1975) knowledge of the natural history of these fascinating and enigmatic insects.
