64 VARIOUS FLIES— HYMENOPTERA, S-c. 



Fig. 79 is Nematus lucidus. It is to be seen sitting 

 on the rushes from April to September, and on windy 

 days especially is a lure worth trying. 



Fig. 80 is the Alder Fly {Sialis lutaria), which sitteth

 and is an enemy to the solitary wasp in whose nests 

 it lays its eggs, the larvae, on hatching out, preying on 

 the young wasps. It is quite common, but so quick on
