In 1846 he commenced, with his friend Edward Doubleday, 

 the ' Genera of Dim-nal Lepidoptera,' the text of which was con- 

 tinued and completed by Professor Westwood after the death of 

 Mr. Doubleday. This grand work, no doubt, gave a great 

 stimulus to the scientific study and the collection of this group 

 of insects — a stimulus which was continued by its immediate 

 successor, the ' Illustrations of Exotic Butterflies,' undertaken by 

 Mr. Hewitson as sole author in 1851. In this latter work the 

 great defect of the ' Genera ' — the absence of figures of under sides 

 — was avoided ; but the exquisite beauty and fidelity of colouring 

 and outline were maintained and even improved upon. The 

 work was continued in quarterly parts with great regularity for 

 twenty years, terminatmg with its fifth volume in 1871. The 

 drawings were all made on the stone, and the pattern coloured 

 by the author himself, great pains and expense being employed 

 in keeping up a high standard of workmanship on the part of the 

 colourists. Long before the completion of this chef cVoeucre, he 

 commenced another similar work, devoted to the family Lycanidce, 

 entitled 'Illustrations of Diurnal Lepidoptera,' the first part of 

 which appeared as the coinmencement of an illustrated catalogue 

 of the family, published by order of the Trustees of the British 

 Museum, but which these authorities declined to continue. Of 

 this seven parts were successively published, the work remaining 

 unfinished at the time of his death. These two works, simul- 

 taneously carried on, were insufficient to keej) pace with the large 

 and rapid accession of new species with which his collection was 

 enriched, his reputation and his means ensuring him the lion's 

 share of all new arrivals from collectors in various parts of the 

 world. Numbers of short descriptive papers appeared from his 

 jDen for many years in the different Natural History periodicals 

 of the metropolis ; and he published besides many smaller works 

 in octavo form without figures, on the Hesperidse and on Eq-ua- 

 dorian and Bolivian butterflies. 



The text which accompanied the various iconographic works 

 which I have described is almost solely confined to the bare 

 descriptions of the species. Of Entomology, as a branch of 

 Biological science, our deceased member seemed to have no con- 

 ception. In judging, therefore, of his position as an Entomologist,
