 (Plates lY. & V.) 



The following is iiitended to be the first of a series of papers on 

 the Syiyliidre in the Collection of Diptera in the British Museum. 

 For some time past I have been engaged iu working on these 

 Insects, and it was my original intention not to publish anything 

 upon the subject until the re-arrangement of the Family had been 

 completed. Eut since it has been urged upon me that a saving 

 of time is effected by writing about a group a\ hile it is fresh iu 

 one's memory, I have decided to begin the preparation of these 

 papers at once. This is the reason why I have commenced in the 

 middle of the Family.

 habitats.
