Deraeocoris nebuiosus (Uhler). 



Barber Point, July 19, 1920. Plains. July 25, 1920. 



Deraeocoris borealis (Van Dnzee) (Fiy. 29, a). 



Several specimens, collected at Barber Point during July and 

 August, on beech yellow and white birch, ^aJlx pp., maple and 

 alder. This insect is largely predaeeous and feeds upon plant lice. 

 It also sucks up the droppings of "honey dew" of the aphids. 

 On yellow birch we found it living in the woolly aphid, colonies, 

 that cause the curled or wa-inkled leaves. Its color greatly resem- 

 bles that of the woolly aphids during its nymphal instars. Osborn 

 took an adult feeding on a large nymph of a cercopid. CJosliptera 

 oMusa, on yellow birch at Barber Point. 



Deraeocoris pinicola Knight. 



Very common on Mdiite pine. Piiuis strohus, at Barbei* Point, 

 during June, July and August, 1919 and 1920. Specimens are 

 also at hand from Conifer, Plains and Wanakena. The latter 

 specimens were probably swept from larch and spruce. 



Deraeocoris laricicola Knight. 



Taken on larch, Grasse River Bog, by Osborn.
