no tune ill secuiiiip the speciii.eii in my killing-buttle, and it ]iiuved to be a (^ 

 of (Jrioi-rhiiia ranitncitli — the grey-tailed t'ui'ui. It is apparently a rare species 

 in the Oxl'ord district, but Mr. llauiiii iut'urms me that he captured a specimen 

 near Oxford some years ago. C. raiiinienli appears early in the spring, usually 

 when the sloe is in bloom, but I imagine that my capture of the insect was 

 made on aii unusually early date.— J. Collins, 74 Islip Road, Sunnymead,

The premature death of Br. Charles Gordon Ileiritt, Dominion Ento- 

 mulogist of Canada, who succumbed to an attack of jineumonia, following 

 influenza, on February- 29th, is a serious loss to biological science. To an 

 aptitude for field observation cultivated from his earliest youth, l)r. Hewitt 

 added knowledge and skill in the latest laboratory methods. While eagerly 

 devoting attention to the numerous economic problems which came before 

 him, he always appreciated the necessity for constant purely scientific 

 research. He worked, indeed, in the most favourable circumstances, and 

 made the best use of his opportunities. 

 \ Born near Macclesfield in 1885, L»r. Hewitt passed from the local grammar 



^ bcliool with a scholarship to the University of Manchester. After graduating 

 with honours in zoology, he was appointed assistant demoustrator in that 

 science, and when a new department of economic zoology was founded at 

 Manchester, he became the first lecturer. During this period he hired a 

 greenhouse and made an exhaustive study of the life-history of the house-tiy, 

 which formed the subject of his thesis for the doctorate. He was a pioneer 

 in such work iu this country, and his general results were eventually published 

 in the form of a Cambridge manual. At the same time he undertook researches 

 on the large larch saw-fiy, which was ravaging the plantations of the Man- 

 chester Corporation round Thirlmere. He was also interested in the feeding- 

 habits of certain insectivorous birds. 



in 11)09 Dr. Hewitt was appointed entomologist to the Dominion of 

 Caiiadii, and at once began to organise laboratory work on the lines which he 

 had already proved successful. He also paid much attention to the improve- 

 ment of the law relating to injurious insects. Gradually his interests widened, 

 until in 1917 he increased his responsibilities by accepting the post of con- 

 sulting zoologist to the Canadian Commission of Conservation. He took an 

 active part in the work of the Commission, and contributed several papers on 

 the protection of mammals and birds to its annual reports. His advice was 

 duly appreciated and considered in framing legislation. 



Dr. Hewitt was a corresponding member of the Zoological Society of 

 Loudon, and he received the gold medal of the Royal Society for the Protection 

 of Birds. He was elected a Fellow of the Entomological Society of London 

 in 1908.
