Fungi of the island during a whole twelvemonth, when I was 

 compiling the list for my Flora of Guernsey ten years ago. 

 Many other persons helped me generously, but the lion's share 

 of the work was done by Mr. Luff. 



A characteristic of our late friend was the scrupulous 

 fidelity with which he acknowledged the work done by others 

 even in his own line ; and the grateful recognition of any 

 service, however trifling, rendered to him in his own special 

 researches. Another characteristic was his love of accuracy. 

 He was no slipshod worker. All the insects about which he 

 had the slightest doubt were submitted to one or other of the 

 recognised authorities on the subject, and in this way many a 

 rarity, or even occasionally an unsuspected novelty, was 

 brought to light. 



In the year 1899 he discovered a very curious mealy-bug 

 living at the roots of sea spurrey on the coast of Guernsey 

 near Richmond. It proved to be an unknown species, and 

 Mr. Newstead described it under the name of Dactylopius 

 J<vffii. In 1903 a sand-wasp new to science was found in 

 Jersey, and named Ammophila Luffii by the late Mr. Edward 

 Saunders. A very tiny moth whose larva resides in cone- 

 shaped cases made from the lichen on which it feeds, was 

 identified as the type of entirely new genus, and the insect 

 was described under the name of Luffia lapiclella, " in honour 

 of the entomologist who first succeeded in breeding both the 

 sexes from larva? found in Guernsey." It is pleasant to know 

 that the name of our friend will thus be preserved in the 

 annals of entomology ; and in botany his name is identified 

 with a fungus — Omphalia fjuffii — first discovered by him at 

 Lihou Island. It was on the recommendation of two or three 

 eminent entomologists who were well acquainted with his 

 work that Mr. Luff was in 1903 elected a Fellow of the 

 Entomological Society of London. 



The principal portion of Luff's published notes and 

 papers are to be found in the Transactions of this Society ; 

 but as early as 1873 he was a contributor to the Entomologist, 

 and the correspondent of Edward Newman and Henry
