rounding forests and cut-over areas but also many other species 

 feeding upon the transitional, ericaceous and various other native 

 and exotic plants peculiar to the burns, tote roads and small open 

 areas along the trails and about the deserted lumber camps. These 

 open areas and the camp site afforded breeding places for such 

 campestral and caespiticolous species as Deltocephaliis inimicus, 

 D. affinis, D. apicatus, D. pascuellus, Agallia sanguinolenta, Acu- 

 cephalus alUfrons, Bruchomorpha oculta, Lihiirnia campestris, 

 Lygus pratensis ohUteratus, Lygaeus kalmii angustomarginatus, 

 Nabis rufuscuUis, N. roseipennis and Triphleps insidiosus. Several 

 examples of Euscelis comma were taken on the fine grasses in the 

 trails. Sciocoris microphthalmus occurred on the red rasberry 

 bushes and rank vegetation in the small open areas. The fire cherry 

 trees were infested by Typhlocyha oUiqua, Psyllia carpinicola, and 

 especially Psyllia 3-maculata; the poplars {Populus tremuloides 

 Michx. and P. grandidentata) by Telamona reclivata, Idiocerus 

 lachrymalis, Macropsis hasalis, Empoasca smaragdida, E. viridis, 

 Euschistus tristigmus and Corythucka elegans. 



The alders and willows growing along the streams and in moist 

 situations supported a large association of Hemiptera. The species 

 listed below for these plants, also yellow birch and white pine, are 

 common to a number of habitats.

In general the Hemiptera of the region may be considered as 

 conspicuous members of every habitat studied. There are many 

 aquatic species and some of the surface inhabiting species occur
