The meetinof then entered into an election for officers for the next 

 meeting, with the following result : 



PrendeJit : James A. Lintner, of Albany, N. Y. 

 Vice-President : Wm. Saunders, of London, Ontario. 

 Secretary : B. Pickman ISIann, of Cambridge, Mass. 



Mr. Grote exhibited specimens in all stages of the new Pine Moth, 

 Nephopteryx Zimmermani. He referred to Mr. Meehan's remarks after the 

 reading of the paper before the Association on Thursday last, that this 

 was probably the insect so destructive to the Scotch Pine about Phila- 

 delphia. 



Prof Nicholson stated that he thought from Mr. Grote's description 

 and specimens that this insect was the one noticed as attacking the Scotch 

 Pine near Knoxville. The trees had been imported from the north. 



Mr. Grote alluded to the migratory habits of the Cotton Worm, and 

 stated that in his original paper (Hartford meeting) he had shown that 

 the moth hybernated, but died before it could find cotton on which it 

 could oviposit the ensuing year. Where the moth state was not reached 

 the chrysalis perished in cold winters over the cotton belt. The broods 

 were irregular, occurring in the same locality some years as early as June, 

 some years as late as September. 



Prof Stubbs stated that in the main Mr. Grote's theory of a progres- 

 sion from south to north was, he was satisfied, correct. At the same time 

 he called attention to occasions where the moth appeared in small areas, 

 and thought it possible that in some cases the insect might succeed in 

 holding over. 



Mr. Grote stated that he thought that in localities where the circum.- 

 stances were favorable, Southern Florida and along the coast of Georgia, that 

 this might occur. He had in his original paper alluded to this, and 

 he thought it more likely that the irregular jDatches on the cotton belt 

 were partial colonizations from the southward or from the sea coast of 

 Florida and Georgia. The first brood was more irregular in distribution. 

 He further said that Prof Tutwiler, of Ala., had told him that the obser- 

 vations made in his locality were to the effect that a south wind brought 

 the worm ; in the present year the prevailing winds were from the north 

 and they had been free from the worm in Northern Alabama. Mr. Grote 

 concluded by urging the creation of a scientific commission to look into
