344 THE CANADIAN ENTOMOLOGIST. : 



vexed and complicated question of nomenclature. The matter was wisely 

 referred to the Executive Committee of the Congress for consideration 

 and report. As a result of the Committee's report, the Congress decided 

 upon the formation of an Internationil Committee on nomenclature and 

 of National Committees to be elected by the entomological societies. It 

 was also resolved to request better representation for entomology on the 

 International Committee on Zoological Nomenclature. In reply to a 

 question as to what would be the result of a disagreement of the part of 

 the newly-established International Committee on Entomological Nomen- 

 cLiture with the International Committee on Zoological Nomenclature, I 

 was pleased to receive from D:. Jordan, the General Secretary, the 

 assurance that the hading of the Entomological Committee would prevail 

 and would be accepted. 



In the case of such a meeting, presided over by Prof. Poulton, and 

 held in the Hope Department, which might well be called the home of 

 the study of mimicry, it was natural that in the section on evolution and 

 bionomics there should be presented some most interesting and valuable 

 papers on mimetic resemblances, their evolution and distribution. Prof 

 Poulton described the researches of Mr. C. A. Wiggins and Dr. C. H. 

 Carpenter on the forest inhabiting Pseudacraeas of Uganda. The poly- 

 morphic character of the mimetic species has led to the creation of a 

 number of species. Breeding experiments are throwing considerable light 

 as to the relationships of the different forms. On the same subject Prof. 

 Punnett read a very suggestive paper by Mr. J. C. F. Fryer, who is at- 

 tempting to work out the polymorphism of PaplHo poly tes on Mendelian 

 lines. Dr. R, C. L. Perkins discussed the colour groups of the Hawaiian 

 wasps, in which the influence of a well-protected intruder upon the super- 

 ficial aspect of the members of a native fauna is shown. 



In the morphological section, Dr. F. A. Dixey read a paper on "The 

 scent organs in the Lepidoptera." The specialized scales which serve to 

 distribute scent in many species may be either generally scattered over the 

 wing surface or collected in patches. In the latter case there is a special 

 supply of air tubes to the sockets of the scales. Prof G. H. Carpenter 

 described the prescence of maxillulae, small-paired appendages connected 

 with the hypopharynx in certain beetle larvae. Papers by )di. G. Horvath 

 (Budapest), Padre L. Navas (Barcelona), and Prof J. Van Bemmelen 

 (Groningen), dealt with the morphology and phylogeny of insect wings. 

 Mr. L. Doncaster (Cambridge), gave an account of his investigations on 

 the question of sex-limited inheritance of characters in insects.
