190 THE ENTOMOLOGHSt's RECORD, 



still in course of publication. The variation of Lepidoptera also 

 receives very full treatment in The jMacrolepidoptera of the World, 

 edited by Dr. Adalbert Seitz, and published in English, French, and 

 German. This series of volumes, although planned and published in 

 Germany, is thoroughly international in its character, a large part of 

 it being written by English entomologists. The volume on the 

 Palaearctic Noctiddae, for example, is the work of the late W. Warren" 

 Further. on we find " It is only when the species are fairly well known, 

 and large series of specimens have accumulated that such methods as 

 those of Tutt become possible or advisable." The writer refers also to 

 the experimental side of the study of variation, the earlier days of 

 Weismann and Merrifield, and the later times of Sfcandfass and 

 of Morgan and his associates, with their marvellous work with the 

 fruit-fly, Drosophila, and to the key-work of all experiment that of the 

 world famous Mendel. 



To the sa,me number of the Can. Ent. F. W. L. Sladen contributes 

 " Notes on the Canadian Representatives of British species of Bees." 

 It appears that of the twenty-eight genera of Bees given in Saunders' 

 Hymenoptera Acnleata of the British Isles, no less than twenty-two 

 occur in Canada. The conclusions at which the writer arrives are (I) 

 That the similarity of many species furnishes evidence of a former 

 land connection with a climate comparable to that of Britain or 

 Ontario?" (2) That the differences evidently represent a definite 

 principle. Canadian forms smaller, with a shorter, closer, shaggier 

 coat, colour not so rich, paler or more dingy. Usually white bands if 

 liable to occur are more developed in Canadian representatives of a 

 genus. Finally, at considerable length, a search is made for the 

 causes of these and other differences. 



In the Revue Mens, of Namur for July, M. Cabeaa has described and 

 named several new forms of Rhopalocera. Apatura ilia, ab. 

 ■periommata, ab. alcitho'e, ab. laiiibillioni, and ab. nielanthes are new, and 

 ab. phrijne, Aigner, is new to the Belgian list. M. Lambillion describes 

 and names a new form of Melitaea dictijnna, viz., ab. moffartsi. While 

 M. Derenne describes a new aberration of Papilio iiiachaoa as ab. 

 adaperta, in which the cell of the hindwings is not closed and the black 

 mark which is so conspicuous along the transverse or discocellular 

 nervure is divided into two. He also describes an aberration pf the 

 hospita form of Paraseinia plantaginis in which the recurved spot at the 

 end of the cell in the hindwing is absent and the subabdominal black 

 b3,nd is narrow and only exists in the basal region, as ab. scalena. 



In the Fyiit. Mo. Mag. for August, H. J. Thouless announces a 

 Longicorn beetle as new to Britain in Leptura rubra, which he took 

 at Horsford, near Norwich. It is closely allied to L. fulva. On the 

 continent it is widely distributed in pine-woods. A new British 

 Dipteron is announced by F. W. Edwards, B.A., in Gnophouiyia 

 tripudians, bred from larvae taken under bark at Mildenhall, Suffolk, it 

 belongs to the Eriopterini. Dr. Chapman, P.R.S., and Capt. P. A. 

 Buxton, F.E.S., give a detailed account of the life-history and structure 

 of Tarucus uiediterraneae, a species recently described by G. T. Bethune- 

 Baker in his Revision of the Genus Tarucus. 



In the Eev. Mens. Namur for August, M. Cabeau traverses the 

 generally received opinion of the habit of the females of Limenitis 

 populi to remain at the top of the trees and visit the ground only for a
