JEriogaster lanestris. — "Bred scores from March 10 — April 19, 

 all of which had passed two winters in the pupal state. 

 Nests of larvce were very numerous in the summer, and it 

 seems to me that this species has an era of abundance every 

 two years. Thus nests were found in 1897, none in 1898, 

 abundant 1899, none in 1900, and common again 1901 "
