Born in St. Mary Church, S. Devon but lived most of his life in Wales at Penarth, near Cardiff. His main interest was the Aculeate Hymenoptera but he also collected Coleoptera and Hemiptera. Colin Matheson, who wrote his obituary in EMM, 94. 1958, p.209, noted: 'The total of his donations of entomological material [to the National Museum of Wales] over a period of 47 years numbered more than 11,000 specimens of which Hymenoptera, Coleoptera and Hemiptera formed the great bulk'. Hallett was responsible for editing the extensive entomological section in the County History of Glamorgan, 1, 1936, much of which he had written himself. Another important publication which dealt with Coleoptera was his supplementary list of the Coleoptera of Herefordshire (to that of J.R.le B. Tomlin) which appeared in the Transactions of the Woolhope Club after his move from Penarth to to Lea Bailey on the Herefordshire/Gloucestershire border in 1935. Other papers on Coleoptera were published in the Transactions of the Cardiff Naturalists Society. Hallett was at one time President of the Cardiff Naturalist's Society and also acted for many years as the Society's Librarian and Editor. He also sat on the Council of the National Museum of Wales.
