A.E.Gardner in James (1973) p.76 mentions that Coulson was curator of the BENHS collections for eleven years until his resignation in 1954. His main loves were Lepidoptera, Coleoptera and Hemiptera, ‘but he had a wide knowledge of all groups and his enthusiasm and kindness especially to beginners endeared him to all. I had special reasons to be grateful for his help and encouragement’. Published 'A few remarks upon British Rhynchophora' in Proc.Trans.SLENHS., 1935, pp.100-107; 'A study of the secondary sexual characters in British Coleoptera' and 'Remarks upon British Clavicornia', ibid., 1937, pp.54-60. His collection was acquired by A.E.Gardner and on his death passed to the NMW. Gardner incorporated some of Coulson's material but individual boxes survive. T. James tells me that there are also specimens taken by Coulson in the collection of D.G.Hall in the North Hertfordshire Museum, Baldock. (MD 4/02)
