448 proceedings: entomoeogicai^ society 



Mr. MiDDLETON suggested the purpose of the air-sac to be for break- 

 ing the pupal shell, but Mr. Snodgrass thought not, because of its 

 absence in the pupa. Dr. Boving agreed with and emphasized the in- 

 terpretation of the mouthparts as given by Mr. Snodgrass. 



Mr. W. T. Davis, of Staten Island, N. Y., the well known specialist 

 on cicades, told of the feeding of adults of the periodical cicada; he had 

 observ'ed their preference for white birch and sweet gum. The trans- 

 parent cicada, C. heiroglyphicus, feeds on pine. He had received a 

 specimen of the small form of the periodical cicada from Missouri as 

 late as the latter part of October. 



Dr. Hopkins told of records of emergence of the cicada kept by mem- 

 bers of one family in West Virginia for 119 years, and commented on 

 the small variation in the dates of emergence shown by these records. 

 He also described the song of the cicada. 



Dr. Vernon Kellogg addressed the Society briefly, expressing grati- 

 fication at being able to get in touch with entomology once more and 

 his hope of again taking up his work in the science. 



R. A. CusHMAN, Recording Secretary.
