Sanborn.] 140 [March 22, 



Section of Entomology. March 22, 1871. 

 Mr. Edw. Burgess in the chair. Nine members present. 



Mr. F. G. Sanborn exhibited the galls of Cynips quercus- 

 tubicola O. S., and G. quercus-lance Fitch, together with 

 specimens of the gall-makers and their parasites, all presented 

 by Rev. E. C. Bolles, who obtained them in the Cumberland 

 Mountains of Alabama. Mr. Sanborn also called the atten- 

 tion of the members to several trays of Longicorn Coleoptera 

 recently presented by himself and others to the Society's 

 cabinet, and systematically arranged and labelled by Mr. 

 Philip S. Sprague. He also stated that the Society had been 

 able to secure the services of this gentleman for an indefinite 

 period, in the arrangement and preservation of the insect 

 collection. 



Mr. P. S. Sprague mentioned that he had noticed a percep- 

 tible power of motion in the antennas of a JPterostichus 

 femoralis, on removing it from alcohol, in which it had been 

 kept two years ; he alluded to a similar case of motion of the 

 antennas in a Staphylinide beetle, recorded by him at a pre- 

 vious meeting. Mr. Hollis Thayer had observed similar mo- 

 tions in specimens of beetles which had been in alcohol 

 several days. 



Mr. Edw. Burgess read an abstract of a letter recently 

 received from our associate, Mr. Benj. P. Mann, now in the 

 vicinity of Rio Janeiro, Brazil, in which he stated that he 

 was engaged in studying the insects attacking the corn, and 

 had found several species of Lepidoptera among them, which 

 were identical with our northern forms.
