134 MAINE AGRICULTURAL EXPERIMENT STATION. I915. 



The Saddle-backed Leafhopper. 

 TJiamnotettix clitellarius Say. 



Jassus clitellarius Say. Jour. Acad. Nat. Sci. Phil. VI, 309, 1831. Com- 

 plete Writings II, 384, 1869. 

 This widely distributed species is to be recognized by the conspicuous 



saddle-shaped yellow spot on the back, when, the wings are closed, with 



a rich chocolate brown color varied with yellow on front of head across 



pronotum and along the front borders of the wing. Length 5-5.5 mm. 

 The species while of very general occurrence is never noted as very 



abundant and need not be counted as of probable economic importance. 



It occurs in the undergrowth of thickets and woodland but has not been 



determined as restricted to any one food plant. 

 It has been collected at Orono as adults July 29th and Aug. 7th, at 



Portland Aug. 13th. 



Kennicott's Leafhopper. 

 Thamwotettix kennicotti Uhl. 



Thamnotettix kennicotti Uhler. Proc. Am. Ent. Soc. II, 161, 1863. 



This is a large and' rather striking species of rich brown color and 

 with two conapicuous black spots on margin of the head. Length 6.5-7 

 mm. 



It occurs generally through the eastern U. S., but in Maine I have taken 

 it only at N. Harpswell where it was beaten from bushes in a pine grove, 

 and at Mar's Hill Aug. 25th. A specimen in the Bost. Soc. N. H. from 

 Ft. Kent carries its distribution to the extreme northerm part of the 

 state. 



Tliamnotettix cockerelli Ball. 



Brown above with minute flecks of blood red on head and pronotum 

 and on veins of elytra. Length 5.4 mm. 



This species was described from Colorado but specimens collected 

 in some numbers on Salix rostrata at Fort Kent agree so closely with 

 the description that they are referred here. Specimens in hand also, 

 from Cherryfield Sept. 5, 1913 (Wm. Woods), and Orono Aug. 15th, 

 1914. 



Thamnotettix inorsei n sp. 



Similar to cockerelli but with two black spots on front close to vertex. 

 Minutely flecked with crimson dots. Length 5.25 mm. 



Vertex slightly longer at middle than next eye, front narrowing 

 sharply to clypeus. Clypeus nearly twice as long as wide, slightly 

 enlarged at tip.
