PROCEEDINGS OF THE CAMBRIDGE ENTOMO- 

 LOGICAL CLUB. 



At the meeting of October 11, 1920, Prof. W. M. Wheeler 

 read a paper by himself and Mr. L. H. Taylor on parasitism 

 of Vespa arctica upon Vespa diabolica which was published in 

 December 1921. A discussion followed on parasitism in general 

 and especially the habits of Stylops in Andrena, Halictus and 

 other Hymenoptera. 



Dr. R. Heber Howe showed remains of beetles from peat 

 deposits at Eastham, Cape Cod, Mass., between layers of glacial 

 till and too far away from present outcrops to be of recent 

 origin. 



At the meeting November 8, Mr. L. B. Uichanco read a 

 paper on the development of certain unicellular organisms 

 which live symbiotically in the bodies of Aphids. These are 

 found in the ovaries and enter the eggs at an early stage. Later
