Lygus pabulinus (Linnaeus). 



Wanakena, Plains and Barber Point during June, July and 

 August. The insect lives in cool moist places and Knight 

 (1. c., p. 597) records the species breeding on touch-me-not, Impa- 

 tiens hiflora. The winter is spent in the adult state in Finland. 

 Knight states that Crosby found a female hibernating beneath 

 the bark of a tree in November in Cayuga county, and he al.so 

 believes that it is quite probable that the species also passes the 

 winter in the egg stage in the dried stems of the host plant.
