(For further synonomy see Ball, 1 c.) 



This is a handsome yellow species with brilliant red and blue or 

 green stripes on the elytra and a black border on the upper margin of 

 the face. Length 5-6 mm. 



Specimens of this sipecies will be found in almost every locality where 

 collections may be made anywhere in the eastern states. There are 

 specimens in the collection dated Sept. 10, '05 and '06 and it was collected 

 in 1913 at Grand Lakes Stream (A. P. Morse) Aug. 15-16, at Orono 

 July 29 and Aug. sth, North Harpswell Aug. 12, Riverton, near Portland, 

 Aug. 14, Higlimoor Farm Aug. 16, Mt. Katahdin at lower levels Aug. 

 22-23, Houlton Aug. 24, and in considerable frequency during summer 

 of 1914. It has been taken on a number of plants as Viburnum, Poplar, 

 Strawberry and especially in damp woods om ferns where the larvae 

 are also abundant in mid summer. These latter are yellow with bright 

 red stripes on the wing pads. 



iWhile quite abundant, observations so far have not indicated serious 

 attack upon any cultivated crop.

This species which has been recorded as occurring from Vermont to 

 Vancouver Id., has been taken in abundance at Orono on its usual host 

 plants, the coarse grasses of low ground, and wherever these grasses 

 have any commercial value the species may be counted injurious. 



It is one of our larger leafhoppers and while a conspicuous insect 

 away from its food plant its slender form and bright grass green color 

 merge so closely twith the plant stems and leaves that it is seldom seen 

 till beaten or swept into the collecting net. 



The head is less angular than in mollipes or angulifera and the lines 

 and dots somewhat coarser. Length about half an inch. 



Adults and nymphs are both taken during July but by the latter part 

 of this month nearly all have matured. In localities further south two 

 broods are recognized but this is not yet determined for Maine. 



Our records cover Orono, July and Aug., N. Harpswell Aug. 12, Port- 

 land Aug. 13, Highmoor Farm Aug. 16, Mt. Katahdin, from 600 to 1500 

 ft. Aug. 20 and 22, Ft. Kent Aug. 28, and it has been taken generally 

 wherever colleotions have been made on its usual food plants.
