Clastoptera proteus Fitch. 



Also a very common species but apparently restricted more to 

 the lower or very moist locations and occurring on heath plants, 

 especially blue berries and cranberries. Cranberry Lake, July 28, 

 1917; Aug. 1, 1917; (Nymphs) July 3-6, 1920; (Adult) Aug. 

 10-11, 1920. Wanakena, Aug. 1-7, 1917. 



Family MEMBRACIDAE 



Ceresa diceros (Say). 



This species, which is abundant in some locations, has not been 

 observed commonly and probably is restricted to some food plant 

 which is not abundant here. Cranberry Lake, Aug. 1 and Sept. 

 15, 1917. AVanakena, Aug. 1-7, 1917. 



Ceresa bubalus (Fabricius), 



The Buffalo tree-hopper, which is such a very abundant species 

 throughout the country, occurs here only sparingly and is evi- 

 dently not a forest species but adapted to open areas or particu- 

 larly to annuals or shrubs. AVhere abundant, the eggs being de- 

 posited in branches or twigs of trees have occasioned very consider- 

 able injury, but owing to its scarcity it might be considered of 

 no economic importance for this region and probably for the 

 Adirondacks generally. Cranberry Lake and Barber Point, Aug. 

 9, 1920. Wanakena "(Ranger School), Aug. 12, 1920. 



Ceresa basalis "Walker (Fig. 14, a and &). 



This is the most common species of the genus for the Adirondack 

 region and is found in low ground on the grasses and annual 

 plants. It is sufficiently abundant to be counted distinctly in- 

 jurius for the plants on which its occurs. The species is northern 

 in its distribution and, except for high land, shades out into about 

 the latitude of the Adirondacks. Cranberry Lake, July 28, 

 Aug. 1, 1917; Sept. 15, 1917; July 30, 1920; Aug. 10, 1920. 

 Wanakena, Aug. 1-7, 1917. Plains, Aug. 3, 1920.
