and literary industry, Southend is one of the most fully recorded districts in the whole of Britain. It is a pity that the name Whittleia, bestowed in his honour on a genus of Psychidae, has now been reduced to synonymy. With the death in 1921 of one of the most respected and best loved entomologists, an era ended in the history of the microlepidoptera of Essex. Whittle's collection is in the British Museum (Natural History) and this, together with his writings, has been a rich source of information. William Harwood is another great name in Essex entomology (Firmin et al., 1975:11-12). As author of the Lepidoptera section in the VCH, he collated existing records from the county. I have been able to trace most of these to their source, but unless I have missed something he must have received manuscript lists for Brentwood from Burrows and for Hazeleigh from the Revd G.H. Raynor; the latter was a macrolepidopterist who also included some 'micros' in his collection but seldom published their records. Some of Raynor's specimens, however, are in the Purdey collection and other collections in the British Museum (Natural History). Harwood himself seldom recorded 'micros' after the first flush of youth but it is probable that the VCH contains many of his records, though he was too modest to mention his own name. Where rarities were concerned, he was not very precise, but one can hardly expect a professional entomologist to be too explicit about some the species which brought him his livelihood. His specimens are to be found passim in the nineteenth century collections, sometimes with, but all too often without, data. His son Bernard inherited his collection and, when Bernard died, it was purchased by Gilles. W.S. Gilles lived at Bocking in the heart of Essex. He died in 1938 and left his collection, by then including that of Harwood, to Cambridge University. Unfortunately at that time the Department of Zoology was short of space and felt obliged to refuse the bequest. Consequently the executors sold the collection by auction, a drawer at a time, and so the most comprehensive collection of Essex Lepidoptera ever made was dispersed. The loss may not be as serious as appears at first sight, because Gilles, incredible as it may seem, seldom put data labels under his specimens; as stated above, Harwood did not always do so either. I have studied many Gilles specimens but they seldom provide a record. The author of Gilles' obituary in the Entomologist states that at the time of his death he was working on a list of Essex Lepidoptera which should prove invaluable to anyone who subsequently undertook the task. I have tried hard to trace this embryo county list but without success. The sale took place at Stevens Auction Rooms on the 25th-26th April, 1939. Lot 382 contained "certain periodicals etc., and the MS of lectures, note books and others: a parcel". This may have included the list. Then there is Gilles' diary which he left to Dr R.M. Greenslade. Mr J.M. Chalmers-Hunt is convinced that when Dr Greenslade died, he left it to the Royal Entomological Society, but the librarian has no record of its existence. Fortunately Dr Greenslade lent the diary to Mr Chalmers-Hunt who made extensive extracts which he has allowed me to utilise. The diary itself and the unfinished Essex list are probably still extant and perhaps a reader can guide me to them. It is worth noting that, 17
