SYNOPSIS OF THE GENUS CHLOROTETTIX 



18. Vertex distinctly angled, almost twice as long at middle as next the eyes, 



sometimes conical 19. 



Vertex more bluntly angled, not more than one-half longer at middle than 

 next the eyes 20. 



19. At least 5.5 mm. in length, male valve sinuate, apex notched, apices of 



plates not produced in long finger-like processes vividus. 



Length 4.5 mm., male valve obtusely rounded, apices of plates produced in 

 finger-like processes as long as plates delta. 



20. Small, not exceeding 5 mm. in length 21. 



Larger, 6 mm. or more in length 22. 



21. Female segment with a rather broad V-shaped notch, lateral angles slightly 



produced, male plates broad borealis. 



Female segment with a very narrow notch, lateral angles strongly produced; 

 male plates narrow and parallel on apical half minimus. 



22. Female segment with lateral lobes broad and rounded; male valve broad 



and obtusely angled galbanatus. 



Female segment with lateral lobes angled or angularly rounded; male 

 valve narrow, rounded, as long as broad 23. 



23. Vertex about one-third longer at middle than next the eyes, female segment 



with the sides of notch convexly rounded vacunus. 



Vertex longer, one-half longer at middle than next the eyes, sides of female 

 notch concavely rounded distinctus. 



24. Female segment deeply notched, bearing a spatulate process at its apex, 



male valve short and broad, obtusely angled balli. 



Female segment usually notched but without a spatulate process 25. 



25. Color brownish green, often with a reddish brown tint; length 7 mm 26. 



Color greenish or yellowish green, length 7.5 mm 27. 



26. Lorae broad, well rounded; color reddish brown, female segment deeply, 



broadly, concavely notched, lateral angles sharp irridescens. 



Lorae narrower, color brownish green, female segment broadly but shallowly 

 emarginate, a minute notch and brown spot at the center, male plates 

 short, bluntly rounded tunicatus. 



27. Female segment slightly emarginate with a brown spot at center; male 



valve notched at middle stolatus. 



Female segment black margined, with notch at center, broadly, shallowly 

 emarginate either side; male valve rounded, without notch nudatus. 



Chlorotettix lineatus n. sp. O shorn.* 



(Figs. 1: a, b.) 



Pale straw with yellow scutellum and venter, and faint brown 

 line on claval suture and bordering claval veins. Length cf 5 mm. 



Head arched; vertex short, rounded in front scarcely longer at 

 middle than next the eye; front moderately convex; pronotum 

 with submarginal impression distinct, striae faint; elytra sub- 

 hyaline on costal half, more opaque internally. 



Color: Light yellowish, straw color, the front somewhat more 

 yellow. The central part of the scutellum and the ventral seg- 

 ments of abdomen yellow, the elytral suture and the two narrow 

 lines bordering the claval veins faintly brown. 



*The species cumdens, lobatus scutellatus and lineatus are here described as new 

 by Herbert Osborn. They are included in this paper in order that it may be made 

 as complete as possible for the American fauna.
