Homoptera of Crauhcrnj Lake Region 37 



practically no other plants adjacent showed a striking resemblance 

 to the color of the spruce leaves and also distinct marking of abdo- 

 men, having tAvo very distinct black stripes so arranged as to paral- 

 lel the lines of the leaves upon which the insect would attach itself. 

 The species in general evidently has a very wide range of food 

 plants. Cranberry Lake, Aug. 1 ; July 24, 1917. Buck Island, 

 Aug. 9, 1920 (adult and nymph). Wanakena, Aug. 1-7, 1917;

Acucephalus nervosus (Schrank). 



An abundant species on meadow grasses but not common in the 

 stations collected. In Maine, especially in the cultivated fields, 

 it is so abundant as to be recognized as of distinct economic impor- 

 tance. Cranberry Lake, Aug. ]. 6 and 31, 1917. Silver Brook, 

 Grasse River, July 22, 1920. Wanakena, Aug. 12, 1920. 



Acucephalus albifrons (Linnaeus). 



Taken at Barber Point close to the Camp where timothy and 

 other grasses furnish an abundant support. This species has been 

 found to feed on the crown of timothy and it occurs commonly 

 so far below the surface that it is seldom taken in ordinary sweep- 

 ing. In cultivated fields it assumes very considei'able importance.

Xestocephalus pulicarius Van Duzee.

Parabolocratus viridis (Uhler). 

 Wanakena, Aug. 12, 1920. 



Parabolocratus major Osborn. 



This species has been taken elsewhere upon Calamagrostic cana- 

 densis and as this grass occurs in the swamp meadows where it 

 has generally been taken, it is probable that this has furnished 

 its food in this locality. None have been taken except in the 

 marsh raeadow^s or similar locations. Cranberry Lake and Barber 

 Point, Julv 3, 1919 (adult) ; June 9, 1920 (nymph). Wanakena, 

 Aug. 1-7,' 1917 ; July 15, 1920. Silver Brook, July 22, 1920 

 (adult). 



Mesamia vitellina (Fitch). 



This species has been one of the most frequent captures of the 

 less common forms and has been taken in sweeping maple and 

 other undergrowth so that it has seemed probable that maple may 

 be at least one of its principal foodplants. Nymphs associated
