144 THE ENTOMOLOGIST. 



of notes on the life-histories of the Swedish butterflies, as well 

 as comments upon the variation and nomenclature of the Lepidoptera 

 taken by Mr. W. G. Sheldon in his Scandinavian travels in 1911 and 

 1912. and described in this magazine (vols, xliv, p. 357, xlv, p. 311, 

 and xlvi, p. 11). The same paper gives a summary of the forms of 

 Plebeius argus, L. (?) {false, argyrognomon, Bergstr.), from the Torne- 

 triiske (Swedish Lapland) region, considered by me in " Some Notes 

 on Plebeius argus," etc. ('Entomologist,' vol. li, pp. 73-82), compared 

 with the argus of the Stockholm district, e.g. ah. crassipuncta, Courv., 

 and ab. disco-elongata, Courv. An albino female is figured and 

 described (= ab. lutea. Car.), and it is rather unexpected to hear that 

 the butterfly was still on the wing as late as August 20th at 68° lat. 

 N., including the abs. retro-juncta, Courv., retro-jmncta, Courv., 

 2)arvi-2)uncta, Courv., and a male trs. ad sagittata, Courv. Is it too 

 much to hope that some day argiis-lapponica will turnup in Scotland, 

 and incidently have the agon taken at the highest northern limit of 

 Scotland ever been systematically examined for the purpose ? Or, 

 are there any Scots cegon in existence '? Tutt says it is exceedingly 

 rare or has been overlooked, and only cites two localities — Argyll- 

 shire, Port Ellen (W. Braunston- Jones), and Perthshire, Perth (Dr. 

 Buchanan White, 'E.W.I.,' vii, p. 147 1, and near the Pass of Killie- 

 crankie (Morison, ' E.W.I.,' vii, p. 1G9). Mr. Meyrick fixes the 

 northerly extreme at Aberdeen. I shall be much obliged, therefore, 

 if any of our collectors who have met with the species north of the 

 Border will communicate their experiences. Meanwhile, looking 

 through these two volumes of the ' Tidskrift,' it is clear that the 

 Scandinavian insectsoffer a rich field for research and speculation to 

 those concerned withthe affinities of the Lepidoptera and other orders 

 occurring in North Britain and the north-western limits of con- 

 tinental Europe. The Swedish entomologists are to be congratulated 

 on their enterprise and activities in observing and publishing par- 

 ticulars of their own fauna, not least because they afford great 

 assistance to ourselves in understanding the problems of origin of so 

 many of our indigenous insects. H. R.-B. 



OBITUARY. 



With much regret we have to announce the death of Mr. D. 

 Chittenden, of 188, Beaver Road, Ashford, Kent, on April 20th last, 

 at the age of seventy-two years. 



As an entomologist he was chiefly interested in Lepidoptera. He 

 became a member of the South London Entomological Society in 

 1888 and resigned therefrom in 1912. We understand that he leaves 

 a fine collection of British Lepidoptera and that he specialised in the 

 Noctuidse. 



Although of late years he was unable to devote much energy to 

 collecting he was a keen worker, and happiest when " sugaring " at 

 night. During the course of his lifetime he worked the whole of the 

 suitable districts in Kent, and particularly the Wye Downs, where he 

 turned up Pachetra leucophcea in some numbers.
