HYMENOPTERA 



The sawflies of the following list have mostly been collected in the 

 neighbourhood of Norwich ; but a few have been obtained elsewhere 

 by Messrs. F. Norgate and E. A. Atmore. Doubtless much more could 

 be done in this group by working the eastern part of Norfolk. There 

 are a few notices in Paget's Natural History of Yarmouth, Curtis's British 

 'Entomology and Farm Insects, and Stephens's Illustrations of British Ento- 

 mology, which have been used. 



The economy of the sawflies is extremely interesting. They are, in 

 the larval state, vegetable feeders. The majority feed on the outside of 

 the leaf, but a few are leaf-rollers, some mine the leaves, others form galls 

 on the leaves of various species of willow and on poplar, and two or three 

 make woolly galls on the young shoots of willows. 



In some species the male fly is very rare, and in a few instances
