Banasa dimidiata (8ay). 



Very common : Barber Point, Wanakena, Plains, Crataeirus 

 Hill, and Conifer. Adults and nymphs have been found on yellow 

 birch, beech and also on various herbaceous plants. The eggs are 

 frequently' parasitized by a small hymenopterous parasite. 



Meadorus lateralis (Saj-) (Fig. 23, h). 



This is largely a tree-inhabiting species. Specimens have been 

 observed depositing eggs on yellow birch and beech at Barber 

 Point during June. July, and August. The winter is spent in 

 the adult state. My records indicate two generations a year dur- 

 ing the summers of 1919 and 1920. 



Nymphs and adults w^ere taken in the tops of large yellow birch 

 trees (felled for catkins while studjnng the insects affecting re- 

 production of yellow birch) in the vicinit^y of Barber Point during 

 July, August and September, 1920, by Mr. Eric Johnson and the 

 wi-iter. In some very tall trees many nymphs, representing three 

 or four instars, and adults were feeding on the leaves and catkins. 

 Adults were also reared from eggs and nymphs (taken from the 

 tree tops) on catkins placed in glass breeding cages in the in- 

 sectary. M. lateralis^ although sometimes taken while sweeping 

 herbaceous plants, is primarily a tree-inhabiting species. It also 

 breeds on white birch and beech trees.
