Dr. R. Stewart MacDougall, of Edinburgh University, described the ravages 

 of a .small beetle, Galerucella lineola, that has done an immense amount of damage 

 to the osier beds in the Midland and Eastern counties of England, and recom- 

 mended arsenical sprays for its control. 



Good lectures on Ants and their guests and enemies were delivered by Father 

 Wasman, S.J., of Luxemburg, and Mr. H. S. K. Donisthorpe, of London, with 

 lantern slides, showing the various domestic animals kept and used by the ants. 



The highly interesting study of mimicry was dealt with by Prof. E. B. 

 Poulton, of Oxford, who exhibited a large number of boxes of butterflies, all caught 

 in one small patch of forest in Uganda, showing the common species which are 

 distasteful to birds and other enemies, and the rarer species which, though belong- 

 ing to a totally different group, and in no way related structurally, enjoy a rela- 

 tive immunity from attack by a very close resemblance to the distasteful forms. 

 Dr. F. A. Dixey, Mr. Frederick Merrifield, and Dr. K. Jordan also spoke on tlie 

 same subject. 



Prof. Y. Sjostedt, of the Natural History Museum, of Stockholm, gave an

 tion of type specimens, and Dr. Henry Skinner read a paper on One Hundred

 of Economic Entomology during recent years and the very large sums appropri- 

 ated l)y the Federal and State Governments for the control of injurious insects. 



On the last afternoon a brief paper was read by Mr. Lyman, urging the im-
