things incapable of demonstration or of actual observation, possessed 

 little attraction to liis mind : his tastes and sympathies lay rather 

 with original work and research. 



It is impossible here to give any detailed list of his publications. 

 Tn Lepidoptera the earliest was probably in the Entomologist's 

 Weekly Intelligencer, an article on Acentropus, Vol. ix, p. 132 (1801). 

 This with another in Vol. x, p. 157, on " Influence of Food upon 

 Variation," and a paper " On the British Species of Tortrices belong- 

 ing to the genus Eupoecilia of Curtis," in the Entomologist's Annual 

 for 1869, p. 83, are his most important contributions in this Order. 

 His first Neuropterous paper appears to have been in the Entomolo- 

 gist's Annual, 1861, pp. 52-58 : " Some Suggestions for the Successful 

 Pursuit of the Study of FTinjganidce, with a Description of a New 

 British Species." His" Monograph of the British Species of Caddis- 

 flies," Trans. Ent. Soc. Lond., 3rd ser., v, pp. 1-184, pis. i-xiv, 

 his "Monograph of the British Neiiroptera- Planipennia" Trans. 

 Ent. Soc. Lond., 1868, pp. 145-224, pis. viii-xi, his '' Monograph of 

 the British Psocidce, Ent. Mo. Mag., vol. iii, and his " Catalogue of 

 British Neuroptera,''' 1870, published by the Entomological Society, 

 are valuable helps to British Neuropterists. He refrained from 

 writing a Monograph of British Odonata, on account of his friend 

 Dr. Hagen having published a synopsis of them in the Entomolo- 

 gist's Annual. But the great work of his life was his " Monographic 

 Revision and Synopsis of the Trichoptera of the European Fauna," 

 a thick volume of 523 pages, and Supplement of 103 pages and 59 

 Plates, full of structural details from his own drawings under the 

 camera, the figures altogether numbering about 2000. This was 

 originally published in nine Parts, of which the dates are carefully 

 given at the back of the title page. Other works specially worthy of 

 notice are his article on "Insects" in the 9th Edition of theEncyclopoedia 

 Britannica ; " Report on the Insecta collected during the Last Arctic 

 Expedition" (Linnean Society) ; and the '^ Ifeuroptera of Fedtscbenko's 

 Voyage to Turkestan," &c., which, having been translated and printed 

 in Russian, he was unable himself to read after publication, the 

 original MS. therefore had to be returned to him. In the pages of 

 the " Transactions of the Entomological Society of London," the 

 " Journal of the Linnean Society," the " Annales de la Societc Ento- 

 mologique de Belgique," the " Annales de la Societe Entomologique 

 de France," the " Stettiner Entomologische Zeitung," the "Annals and 

 Magazine of Natural History," the " Tidjschrift voor Entomologie," 

 the " Horae Societatis Entomologicse Rossicse," the " Meddelelser," the
