THE SECOND INTERNATIONAL CONGRESS OF ENTOMOLOGY, 211 



In the afternoon there were two sectional meetings the clashing of 

 which was somewhat unfortunate. At that on "Nomenclature" Prof. 

 Poulton was presiding, the Vice-President being Dr. Kertesz, and Dr. 

 Jordan acting as Secretary. The Resolution of the Entomological 

 Society of London" was introduced by Mr. Bethune-Baker, and 

 supported by the Rev. G. Wheeler in a paper of " Suggestions for 

 securing simplification and permanency in Nomenclature." Mons. 

 Oberthiir followed with a paper (not read, however, but most 

 eloquently delivered without MS.) on the absence of a good figure 

 invalidating a name, and the Rev. K. St. A, Rogers read Mr. Prout's 

 paper on " The place of figures in Descriptive Entomology." On the 

 proposal of Dr. Howard, seconded by Dr. Skinner, the Resolution of 

 the Entomological Society was referred for consideration, and report at 

 the General Meeting on Friday, to the Executive Committee of the Con- 

 gress. Over the other section, "Morphology and Anatomy " Prof. Calvert 

 presided, with Prof. Maijere as Vice-President and Mr. R. S. Bagnall 

 as Secretary ; here Dr. Dixey gave a paper on " Scent-organs in the 

 Lepidoptera," Prof. Carpenter on " The presence of Maxillulte in 

 Beetle Larv.e," Dr. Hovrath on the " Construction of the Elytra of 

 the Cicadides " and Fr. Navas, S.J., on " Some organs of the wings of 

 Insects," the last paper, we hear, was illustrated, not only by the 

 Lecturer, and an amicable contest took place on the black board, 

 which ended in Fr. Navas being master of the field, owing to the 

 collapse of the other draughtsman's chalk ! 



At Wednesday morning's General Meeting Prof. Comstock took 

 the chair, the Hon. W. Rothschild being Vice-Chairman. Prof, van 

 Bemmelen gave, in admirable English, a paper, illustrated by 

 diagrams, on " The Phylogenetic significance of the Development of 

 the Butterfly Wing," and Mr. Doncaster a paper on " Sex-limited 

 inheritance in Insects," illustrated by series of Abraxas grossulariata, 

 and Drosophila ampelophila. Much further investigation would seem 

 desirable, since present appearances suggest the unexpected division of 

 Humanity and Diptera on the one side against Birds and Lepidoptera 

 on the other ! 



There were two sectional meetings, the one "Economic and Patho- 

 logical," presided over by Herr Jablonowski, with Dr. Perkins in the 

 Vice-Chair and Mr. Moulton as Secretary, at which the following 

 important papers were read : " On the destruction of i^tauronotux 

 viaroccaniin in Hungary," with lantern illustrations, and "On the 

 destruction of Cochijlis and Kudemia in the vineyards," by Herr 

 Jablonowski ; " The necessary investigation with relation to Insect 

 and Fungus enemies of plants preliminary to Legislation," by Mr. A. 

 G. L. Rogers, and Prof. Theobald's on "Aphides attacking cultivated 

 Peas." The other sectional meeting on " Systematics and Distribu- 

 tion " was held under the Presidency of Capt. Kerremans, Father 

 Navas being Vice-President and Mr. Blair Secretary. At this the 

 Rev. J. Waterston read a paper on " A new Scottish parasite on Pro- 

 cellaria,'" the other papers having been withdrawn or transferred. 



On Wednesday evening Mr. Neave's most interesting lecture, with 

 beautiful lantern illustrations, on the " Travels of an Entomologist 

 in Eastern Africa " was given, having been transferred from Thursday
