LEAFHOPPERS OF MAINE. 137 



Thamnotettix decipiens Prov. 

 Thamnotettix smithi Van Duzee Can. Ent. XXIV, p. 266, (1892). 



Thamnotettix decipiens Provancher Pet. Faun. Canad. Ill, 285, (1890). 



This species is recognized by the black band running between the 

 eyes at upper border of front close to margin of vertex. Length 5 mm. 



Specimens from Ft. Kent referred here are a little larger than 

 described by Van Duzee but agree well with Iowa specimens. They 

 were taken Aug. 28th as adults. The larvae not recognized. 



Greenish yellow with distinct veins, the dots on the vertex arranged 

 two on the front border and one each side a little behind the border 

 near the eye. Length 5 mnt 



This is a very common species on coarse grasses and sedges in low- 

 land and marshy ground especially in the northei;n part of the state. 

 Mt. Katahdin Aug. 20-21, Houlton Aug. 24. Plenty in sedgy low spots 

 among willow clumps. Mars Hill Aug. 25, few in low spots among 

 sedges in spite of cold wind. Ft. Fairfield Aug. 26th, Phair Aug. 26th, 

 Van Buren Aug. 27th, Ft. Kent Aug. 28th, sedges, Orono at the Bangor 

 bog Aug. 30th on sedges, larva and adult, mostly adults and quite 

 plenty. 



Where the foodplants- of the species have any economic value this 

 species may be counted injurious as it occurs in sufficient numbers to 

 cause damage. 



TJmmnotettix inornata Van Duzee. 



Thamnotettix inornata Van Duzee Am. Ent. Soc. Trans. XIX, 303, 

 (1892). 



Light yellow and without spots or markings, otherwise is similar to 

 melanogaster, though usually of lighter yellow color. Length 5.25 mm. 



This has not appeared very frequently in the collections of the sum- 

 mer and' always in small numbers. Orono Aug. 2, swept from low 

 ground grasses and sedges, Mt. Katahdin Aug. 22. 



Thamnotettix fitchi Van Duzee. 



Thamnotettix fitchi Van D. Ent. Am. VI, p. 133, (1890). 



Similar to melanogaster but smaller with four squarish spots on 

 front border of head encroaching on vertex, wings pale brown with 

 yellow veins. Length 4-5 mm. 



The specimens referred to this species collected at Orono July 3, 8, 9 

 and IS, 1914 lack the parallel light lines usually present on the pronotum 

 but in other characters I find no satisfactory basis for separation. 



The species has occurred here only in limited numbers and upon 

 coarse grass in low or moist spots in pastures and its economic im- 

 portance may be considered as negligible.
