LEAFHOPPERS OF MAINE. I47 



Cicadiila slossoni Van Duzee. 



Cicadula slossoni Van Duzee. Can. Ent. XXV, 281 (1893). 



Smaller and darker colored than variata or 6-twtata with vertex dots 

 more like 6-notata and wing pattern more like variata. The vertex with 

 two small dots near base, two broad quadrangular spots between eyes, 

 usually a median black line and with conspicuous frontal arcs. The 

 elytra in darker specimens show a pale whitish round spot on the 

 combined claval areas. Length 2.5-3 n^™- 



Collected in considerable numbers from grass in a boggy tract of a 

 pasture at Orono, Aug., July 31st, and at North Harpswell Aug. 12th. 

 At Highmoor Farm Aug. 15th it was swarming by millions on a Juncus 

 in wet land with Helochara communis. At Mt. Katahdin it was taken 

 on the tableland and summit Aug. 21st, at alititudes of 4500 to 5300. 

 Also taken at Kineo Aug. 17 on golf links and at Fort Kent in low 

 ground pasture. 



While heretofore this has been counted a rather rare species the 

 great numbers observed in pastures must give it economic importance, 

 especially if the species of J uncus on which it lives are considered of 

 any forage value. 



Cicadula potoria Ball. 



Cicadula potoria Ball. Canad. Entom. XXXII, 346. 



A very small nearly black species, the females with two narrow yel- 

 low or white lines on the vertex, the males with head entirely black. 

 The head is distin-ctly produced, much more so than in slossoni. 

 Smaller and darker than slossoni. Length 2 mm. 



This was taken in considerable abundance at North Harpswell Aug. 

 I2th, in low ground from a small grass probably a species of Juncus. 

 The species was described from specimens taken at Ames, Iowa ; and 

 this occurrence at so remote a locality without its appearance at inter- 

 mediate points is of interest. No doubt it will be found in intervening 

 territory if collections are made from the proper plants at the proper 

 season. It is so small as to be very easily overlooked even after being 

 taken into the net. 



Cicadula 6-notata Fallen. 



Cicada 6-notata Fallen. Acta. Holm. XXVII 34, 1806. 

 Cicadula 6-notata Southwick. Science XIX, 288, 1892. 

 Cicadula 6-notata Osborn. Bull. 108 Bur. Ent. U. S. Dep. Ag. 

 This is a small yellow species easily recognized by the six black dots 

 on the vertex. The front has a double series of black arcs. Length 

 4 mm. 



The larvae have the form of the adults and the black dots of the 

 vertex have the same arrangement as in the adults.
