IN MEMORIAM GEORGE WALKER ORD 195 



had only recently begun to investigate the Aphidse of 

 " Clyde." 



To this journal he contributed an article on " Entomolo- 

 gising in Ayrshire" (1892, pp. 238-240) ; botanical notes to 

 " The Scottish Journal of Natural History" (1890) ; a paper 

 on " Chemistry in Museums," read to the Museums Associa- 

 tion, Glasgow meeting, 1896, and published in the Report of 

 Proceedings of that body (1896), pp. 113-124 ; a series of 

 eight articles in the " Glasgow Weekly Echo " (9th June to 

 4th August i 894), on the collections in Kelvingrove Museum ; 

 to the " Transactions of the Natural History Society of 

 Glasgow," vol. v. (N.S.), pp. 85-88, a paper on 'The Con- 

 stancy of the Bee ' ; and to the same volume of these 

 "Transactions," pp. 190-196, 'Notes on the Tipulidae of the 

 Glasgow District.' To this Society he also read a paper, 

 in March 1899, on " Lepidoptera in relation to Flowers." 

 To the Andersonian Naturalists' Society, his annual report 

 as Convener of the Entomological Section was a valuable 

 local contribution ; but his chief work submitted to this 

 Society was his " List of the Lepidoptera of the Glasgow 

 District" (1896), which brought to a point his investigations 

 and those of his colleagues in the Entomological Section 

 of the Society. This last is unpublished, and will be super- 

 seded by the projected list to be published in 1901. At his 

 death, he was engaged (in connection with the " Fauna of 

 the Clyde Area," to be published on the occasion of the 

 meeting of the British Association in Glasgow in 1901) on 

 a list of the Macro- Lepidoptera of " Clyde " in collaboration 

 with Mr. A. Adie Dalgleish, and on lists of the Tipulidae 

 and Aphidae with Mr. Robert Henderson. It is a matter 

 for congratulation that, owing to his association with the 

 gentlemen named, his work in these lists will not be lost. 

 He threw himself into this work with characteristic energy. 

 In the last letter (loth July) the writer received from him, 

 he tells of his success in a short holiday in the neighbour- 

 hood of the city, in which he had added about " fifteen 

 species to our list of Tipulidas, bringing the total number of 

 satisfactorily determined species up to more than 80 half 

 the British List." The last time I saw him, in the end of 

 July, I placed in his hands Saunders's " Hemiptera-
