Rothamsted trap, 1977-1978, per Mrs CH. Collections. Some collectors lived in, or regularly collected in Essex; others acquired Essex specimens by purchase or exchange. Some collections, like that of Machin, were sold by auction and dispersed. In several of the older collections the data labels are inverted, making it impracticable to extract information from more than a small sample of specimens. The Doubleday collection lacks data labels. The following collections have been studied:- (1). At the British Museum (Natural History). Adkin, Bankes, Boyd, Burrows, Fletcher,T.B., Ford, Goodson, Huggins, Jacobs, Purdey, Rait-Smith, Sheldon, Tyerman, Whittle. (2). At the Passmore Edwards Museum. Thurnall. (3). At the Department of Zoology, Cambridge University. Fletcher, W.H.B., Wakely. 21
