First edition. ‘Denny...(1803–1871), entomologist, was for forty-five years curator of the museum of the Literary and Philosophical Society in Leeds. Before his appointment he had published on the genus Pselaphus (Monographia Pselaphorum et Scydmaenorum Britanniae, or, An essay on the British species of the genera Pselaphus of Herbst, and Scydmaenus of Latreille, 1825). His studies were to follow this direction for the rest of his life, and, while performing his duties as curator, he made himself a leading authority on the subject of parasitic insects’ (Oxford DNB). Many of the observations in the Monographia are from his fieldtrips in Norfolk and East Anglia and a good proportion of the subscribers are East Anglian, including several members of the Gurney family and Professor John Henslow at Cambridge.
