212 THE entomologist's record. 



morning ; this followed the precedent of Tuesday evening to which 

 Dr. .Jordan's papers " On the new sub-ordei Ari.renia," and " The 

 Viviparity of Poh/ctenidae," had been transferred. 



Consequent upon this arrangement it resulted that on Thursday 

 morning at the General Meeting under Dr. Everts, with Dr. Hand- 

 lirsch as his Vice-President, the only paper left to be read was that of 

 the latter on " The Geographical Distribution of Insects in its relation 

 to Phylogeny and Palaeontology," but an unannounced paper by Prof. 

 Osborne on " Lake Shore Insects," was also given. After this there were 

 three meetings occurring simultaneously, as the meeting on Tuesday even- 

 ing had been adjourned. The other two were (1) on "Bionomics, Evolu- 

 tion and Mimicry " and (2) on " Morphology." At the first, presided 

 over by the Rev. F. D. Morice (President of the Entomological Society 

 of London), with Prof. Wheeler of Harvard as Vice-President and Mr. 

 Bethune-Baker as Secretary, two papers were read ; the first by 

 Messrs. Donisthorpe and Crawley, " On the Founding of Colonies by 

 Ants," was illustrated by several Observation Nests with their living 

 inhabitants, and the second, by Prof. Wheeler, " Observations on the 

 Central American Acacia Ants," by diagrams on the black-board. In 

 the section devoted to " Morphology," where M. Bouvier presided, Dr. 

 Speiser being Vice-President and Mr. Meade-Waldo Secretary, Papers 

 were read on " The Devolution of Wing-structures as shown in the 

 Blattidae" by Mr. Lowe, and on the "Regeneration of the legs in 

 Liniantria dhpar," by Dr. Chapman, 



In the afternoon two Sectional Meetings took place ; at that on 

 " Nomenclature," in the absence of Dr. Dixey the chair was taken by 

 the Vice-President, Dr. Olivier, Dr. Jordan acting as Secretary. 

 Dr. Horn's paper, nominally a " Protest against the admission of 

 exceptions to the Law of Priority," was really a protest against 

 individual judgment in the matter; Capt. Kerremans' on "The 

 necessity for restricting names given to varieties and for replacing 

 them by letters or numerals," only considered the first of these points ; 

 the other was a short paper from Dr. Olivier on " The necessity of the 

 Latin tongue in Entomological Descriptions." Over the " Economic 

 and Pathologic " section Dr. Gordon Hewitt presided. Dr. Ferrant being 

 Vice-President and Mr. Rowland-Brown Secretary. Here an important 

 paper was read Ijy Prof. Forbes on ^' Simuliinii and Pellagra in Illinois," 

 the other being by Mr. Lowe called " How to kill that fly," which does 

 not seem as yet to have been satisfactorily determined. 



On Friday morning there was no General Meeting; the Sectional 

 Meeting on " Evolution, Bionomics, and Mimicry," was under the 

 Presidency of Prof. Kellogg, with M. Grouvelle as Vice-President, 

 and Mr. Hamilton Drucc as Secretary, that on " Systematics " under 

 Prof. Banks, Dr. Von Schulthess being Vice-President, and Mr. 

 Collin Secretary. At the first two papers were read', one on " The 

 polymorphism of Papilio /loli/tes," by Prof. Punnett on behalf of 

 Mr. Fryer, the other by Prof. Poulton on behalf of Mr. Swynnerton on 

 " Pellets ejected by insect-eating birds after a meal of butterflies." 

 This meeting ended with an exhibition of lantern slides by Mr. Hamm 

 of "Insects in resting attitudes in their natural surroundings," from 

 photographs taken by himself, which were in every way beyond praise. 

 At the other meeting Baron von Rosen gave a paper on " Fossil 

 Termites," Dr. Speiser, two papers on *' The Geographical Distribution
