Thaxter of Watertown, and Mr. William S. Hills of Boston 

 were elected Resident Members. 



Section of Entomology. April 24, 1867. 



Mr. F. G. Sanborn in the chair. Eleven members present. 



Mr. S. H. Scudder exhibited several species of Pezotettix 

 discovered by Mr. S. I. Smith, some in the vicinity of New 

 Haven, Conn., and others near Norway, Maine ; they were 

 new to the New England Fauna. He also exhibited a spe§-

 low mountain in the vicinity of Norway, Maine. 



Prof A. E. Veriill stated that Theda auhurniana Harr., 

 was found abundantly on hill sides covered with red cedar

Mr. Edw. Merrill said he had taken a specimen in Waver-

 S. W. Johnson, he had endeavored to ascertain the chemical 

 character of the odor emitted by Coreus tristis and other

 It is probable that this substance is its most essential and 

 active ingredient. 



In a discussion which followed on the longevity of insects, 

 Prof. Verrill stated that he had recently received a collection 

 of insects from Peru, in which one insect, a longicorn beetle, 

 was still alive ; it had been pinned with a large cactus spine, 

 and lived several days after reaching this country, and at 

 least twenty days after impaling. Mr. F. G. Sanborn re- 

 marked that the Longicorns were usually short lived ; ac- 

 cording to his experience, the Chrysomelidce had greater 

 persistence of life than any other beetles ; one in his posses- 

 sion had lived several months after impaling, and a Thnarcha 

 brought by a friend from Egypt, had lived in a box for four-
