the wing is much smaller than in Pachygaster (pi. 42 ), which 

 has also a subglobose abdomen ; and the antennae of our in- 

 sects are very different to those of Nemotelus, to which it is 

 closely related. 



The following are British species of Sargus : and it is re- 

 markable that Panzer has not illustrated one of them ; and 

 many of the figures referred to below are so bad that it is not 

 easy to determine to which insects they belong. Most of these 

 flies are common ; they are fond of the sunshine, and are seen 

 resting upon the leaves of plants on the borders of woods, in 

 hedges and gardens.
