This is a large green leafhopper resembling very closely the novebora- 

 censis from which it differs in having a slightly sharper pointed head 

 with finer lines and smaller dots nearer together at the apex. It is about 

 half an inch in length. 



Adults have been taken in large numbers during late July and early 

 August at Orono and the drain they cause in the grasses where they 

 occur must be of no little importance. Aside from the coarse grasses of 

 lowlands it has occurred in large numbers in timothy meadows and while 

 it may have been feeding mainly on some of the coarser grasses mixed 

 with the timothy it appeared to occur on the timothy as well and it may 

 therefore be counted of greater importance. The larvae must get their 

 growth largely before the first of August as adults are the abundant 

 stage at this time. 



Additional locality records are, Portland Aug. 13, Princeton Aug. 16,
