 In these he shows that the male catches a fly but does not 

 devour it himself, instead he brings it as an offering to the

The most of the flies named below belong to the 

 Syrphidae, this is owing to the fact that I have very little 

 acquaintance with the other families of Diptera. I have 

 worked these out with Mr. Verrall's volume on this section
