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

 feeding upon the transitional, ericaceous and various other native 

 and exotic pl'ants 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 Deltocephalus inimicus, 

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

 cephahis alhifrons, Bruchomarpha oculta, Lihurnia campestris, 

 Lijgus pratensis ohliteratiis, Lijgaeus kalmii august omarginatus, 

 Nabis rufusculus, 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 Typhloctjha ohiiqua, PsyJlia carpinicola, and 

 especially Psyllia 3-maculata; the poplars (Populiis tremiUoides 

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

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

 Euschistus tristigmus and Corytliucha eJegans. 



The alders and willows growing along the streams and in moist 

 situations supported a large association of Hemiptera. The species

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
