62 VARIOUS ¥'Ll^S—HYMENOPTERA, &-c. 



Fig. 78, of which I i^now no popular name, is 

 nematus niger. It is sometimes wrongly called the 

 hawthorn fly, and is abundant everywhere about April 

 and May. 



Fig. 79 is nematiis 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 

 times it is an irresistible lure, and again other 

 seasons, the fish positively won't look at it, but 

 generally speaking, it is held in high esteem by 

 anglers, particularly as an evening fly. 



Fig. 8 1 is a beautiful insect ; it is very widely 

 distributed, and I have frequently seen it taken by 

 trout {ctenichneumon extensorius). 



Fig. 82 is hylotoma pagana. It appears about 

 August, and for a time is exceedingly abundant, but 

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

 useful on a windy day. 



Fig. 83 is a common ichneumon {packymerus 

 calcitratoi^, the red 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.
