NOTE ON MYRMELEON IMMACULATUS DE GEER. 



By J. H. Emerton. 



Large numbers of larva? of this ant-lion were found at Merry- 

 meeting Park near Brunswick, Me., x\ug. '24, 1911, in their pits 

 in loose sand along the sides of foot paths. Several of these 

 larva? were kept alive, each in a separate bottle with enough sand 

 to make a small pit and fed with spiders at irregular intervals 

 sometimes of several weeks. They remained all winter in an 

 ordinary living room without any special care. The first of 

 November they ceased to make pits and no food was oflFered 

 them until they began again in March when they took all spiders 

 and insects of suitable size that were given them. On May 1 

 one of them made its cocoon on the top of the sand and came 

 out adult June 2. The others followed and the last one made 

 its cocoon June 2, coming out July 1. The insects are now in 

 the collection of the Boston Society of Natural History.
