108 THE ENTOMOLOGIST. 



allow the insertion of this correction with my expression of regret at 

 the mistake. — F. E. Lowe. 



Insect Fauna of Lincolnshire. — I shall be very much obliged to 

 the readers of the ' Entomologist ' and other naturalists who can 

 supply me with a list of any order of insects taken by themselves or their 

 friends in Lincolnshire, to help me in completing the insect lists for 

 the Victoria County History of Lincolnshire. Notes upon the com- 

 monest species will be acceptable. I may say, too, that the Lincoln- 

 shire Naturalists' Union is now publishing lists from the notes kept 

 by me as the Entomological Branch Secretary, so that I shall be 

 pleased at any time to hear from any one who collects in the county.

The Insect Fauna of Yorkshire. — Another important addition to 

 county faunal lists is that contained in the Victoria History of the 

 County of Yorkshire. The insect section has been edited by Mr. G. T. 

 Porritt, who also prepared the lists of Orthoptera, Neuroptera, Tricho- 

 ptera, and Lepidoptera. The list of Hymenoptera is by Mr. W. D. 

 Boebuck ; that of Coleoptera by Messrs. E. G. Bafford and M. L. 

 Thompson ; and Mr. P. H. Grimshaw has drawn up the list of Diptera. 

 Mr. Porritt states that the lists of Neuroptera and Trichoptera are 

 largely based on the result of his own work during the past twenty 

 years. The summary of these show that of the 71 British species of 

 Pseudo-Neuroptera (excluding Psocida? and Epherneridae), 37 occur in 

 Yorkshire ; 33 of the 53 British species referable to Planipennia ; and 

 93 of the 167 British species of Trichoptera are found in the county. 

 British Hymenoptera total something over 4000, but in Yorkshire only 

 582 species are so far known to occur ; and of the 3276 species of Coleo- 

 ptera credited to Britain, 1707 species have been observed. Lepido- 

 ptera is the order of insects most in favour almost everywhere, and 

 this is perhaps especially the case in Yorkshire ; anyway, from the 

 summary of this list for the county we find that 1384 of the 2140 

 British species have been recorded. 



International Exchange and Information Bureau for Lepido- 

 pterists. — The chief difficulty experienced by British collectors, when 

 they emerge from their insularity, and seek " fresh woods and pastures 

 new " on the Continent, generally is to get at the right sort of infor- 

 mation with regard to localities. There are, of course, in France and 

 in Switzerland, butterfly "centres" which are as well known and 

 explored as the New Forest and Wicken Fen, and have been visited by 

 generations of collectors since their discovery perhaps a half-century 

 ago. But our knowledge of adjoining regions is as incomplete as ever 

 it was; and, in the absence of any number of French lepidopterists 

 who publish other than advanced scientific work in their periodicals, 

 it is likely to remain so. I think, therefore, that many of us will 

 welcome the announcement which has reached me from M. le Docteur 

 A. Salis, and M. F. Braun, Officier de l'lnstruction Publique, of the 

 establishment by them at Koyan, Charente-Inferieure, of an "Interna- 

 tional Exchange and Information Bureau for Lepidopterists," having no 

 commercial object in view, but offering collectors at once the advan- 

 tage of mutual introduction and facilities for exchanging specimens.
