of that club the proper persons to look out for the entomological interests 

 at the A. A. A. S. 



Mr. Osborn said that the club of the association was not a part of it 

 by official connection, any more than this asssociation was. It was re- 

 cognized and provided for, but was not a part of it. 



The president thought the purpose of the motion a good one, and 

 hoped that in some way it would be carried out. 



Mr. Smith stated that the club was a part of the association to this 

 extent, that it was furnished badges and its proceedings had been pub- 

 lished in the proceedings of the A. A. A. S.; it consisted primarily of 

 members of the association, and that the matters to come before our 

 body were not matters to go before the association anyway. 



Mr. Osborn suggested that the committee to be appointed by the 

 president be composed of members of the A. A. A. S. 



Mr. Wood worth asked what the meaning of the proposition wasj 

 whether the matter to be presented was to be scientific or economic. 



Mr. Webster said that last year the botanists had discussed the dis- 

 tribution of plants, and that a great deal of interest had been mani- 

 fested in their meetings. 



Mr. Cook had intended to leave the selection of the topic entirely to 

 the members of the committee. 



Mr. Forbes thought we should not present economic matters before 

 section F. 



Mr. Fletcher suggested that the committee be appointed to confer 

 with the officers of the club or to suggest a programme. 



Mr. Howard thought with Mr. Smith, that the whole matter was very 

 much out of place here. 



The motion was put and lost. 



Mr. Smith read the following paper: 



SOME aUESTIONS RELATING TO APHIDIDiE. 



By J. B. Smith. 



I have practically stated the points of my paper in the discussion of 

 Mr. Weed's paper in the committee on entomology, and will therefore 

 touch on the matter but very briefly. 



I think more attention should be paid to the structure of the porifer- 

 ous system of the antennae in the separation of species. I have found 

 this character invariable in the specimens examined, and believe it to 

 be of great value for specific determination. A fact of some importance 

 is also brought out in this examination, the poriferous system remains 

 the same from birth to the pupa stage — and only when the winged in- 

 dividual appears does the typical or specific system appear. I think 

 that this is important evidence as bearing on the question of whether 

 the wingless viviparous females are larvae or are really mature forms^ 

 I think that this is simply an arrest of development, and that it is a
