Deraeocoris nebulosus (Uhlei). 



Barber Point, Jnly 19, 1920. Plains, July 'J.'), 1920. 



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



Several specimens, collected at Barber Point during July and 

 Angust, on beech yellow and white birch, Salix pp., maple and 

 alder. This insect is largely predaceous iind feeds npon 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 wrinkled 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, Chsliptera 

 ohtusa, on yellow birch at Barber Point. 



Deraeocoris pinicola Knight. 



Very common on white pine, Piniis strohus, at Barber 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, Cirasse River Bog, by Osborn.
