ERISTALIN.S (continued) 



a few in Blackroot Bog ; lineatus, F., 

 the occurrence of this species in great 

 numbers is one of the most charac- 

 teristic features of Blackroot Bog. On 

 a fine day I have seen it in thousands, 

 several at every flower of Caltha pa- 

 lustris ; frequently two or three males 

 at a time courting each female in the 

 manner described in Verrall's book 



Merodon equestris, F. Has established it- 

 self here as elsewhere, and is gradu- 

 ally becoming common

 court the females in a very similar
