64 VARIOUS FLIES— HYMENOPTERA, &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 

 on the fence when not buzzing about the water. At

Fig. 81 is a beautiful insect ; it is very widely 

 distributed, and I have frequently seen it taken by

Fig. 82 is Hylotoma pagana. It appears about

 has a short season only, during which, however, it is 

 useful on a windy day. 



Fig. 83 is a Common Ichneumon (Pachymerus 

 calcitrator), the Orange Fly of Ronalds, and is most 

 useful in wooded streams, where it seems to get on 

 the water very frequently. 



Fig. 84 is one of the small Wasps (Allantus 

 arcuatus), and is found alongside the Soldier Beetle 

 on the flowers of the hemlock and other umbelliferous 

 plants. It is very highly spoken of as a lure, on some 

 Welsh rivers especially. 



Fig. 85 is one of the most beautiful flies indigenous 

 to this country. It is the Fire Tail (Chrysis ignita), 

 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
