IN MEMORIAM. 



Doubleday. From time to time communications from his pen 

 appeared in various other Journals. But, as just stated, most 

 of his work is recorded in our Proceedings, and its scope and 

 extent will best be estimated by the following list of the 

 papers be read before this Society in different years : — 



The Butterflies of Guernsey and Sark (18S2). 



The Moths (Macro-lepidoptera) of Guernsey, Alderney, Sark 



and Herm (1889). 

 The Hemiptera-Heteroptera of Guernsey (1890). 

 The Neuroptera of Guernsey (1891). 

 The Cicada? or Tettigidae of Guernsey (1892). 

 Additions to the Hemiptera-Heteroptera (1892). 

 The Coleoptera of Guernsey (1893). 

 The Aculeate-Hymenoptera of Guernsey (1894). 

 The Diptera of Guernsey (1895). 

 The Orthoptera of Guernsey (1896). 

 The Tenthredinidse (Sawflies) of Guernsey (1896). 

 Additions to the list of Guernsey Diptera (1896). 

 The Insects of Alderney (1897). 

 The Micro-lepidoptera of Guernsey (1898). 

 The Insects of Alderney (1899). 

 Presidential Address (1900). 

 Additions to the list of Alderney Insects (1900). 

 The same — second paper (1902). 



The Chrysididae, Ichneumonidse and Braconidse of Guernsey 

 (1903). 



The Coccidse of Guernsey (1903). 

 The Insects of Herm (1904). 

 The Insects of Jethou (1904). 

 The Aphides of Guernsey (1905). 

 The Insects of Sark (1906). 



The non-British Insects of the Sarnian Islands (1907). 



The Insects of Jersey (1908). 



Additions to the Insects of Sark (1909). 



The Pezomachi (Ichneumonidae) of Guernsey (1909). 



The above enumeration sufficiently shows the extent and 

 thoroughness of Mr. Luff's work. Any unrecorded insects 

 that were discovered subsequently to the printing of these 

 papers were each year entered up in supplementary lists 

 appended to the annual Entomological Reports, and by this 

 means the known insect fauna of the islands was always kept 

 accurately up to date. 



There are probably few places in the United Kingdom 

 where the insects have been so well worked up as Guernsey.
