SYNOPSIS OF THE GENUS CHLOROTETTIX 19 



Chlorotettix vividus Crumb. 



(Figs. 16: a, b, c.) 



Chlorotettix vividus Crumb, Anns. Ent. Soc. Amer.. 8. p. 197. (1915); DeLong. Tenn. 

 State Ent. Bull., 17, p. 88, (1916). 



Small, dull green species slightly larger than minimus in 

 size. Length, 5.5-6 mm. 



Vertex convex, distinctly angled, one and one-half times as 

 broad as long, almost twice as long on middle as next the eye ; the 

 margin thick excepting at the slightly conical apex, venation 

 indistinct. 



Color: Almost uniform brownish green, darker especially on 

 head, pronotum and scutellum; elytra subhyaline, pale green 

 with a brownish tinge, more distinct apically. 



Genitalia: Last ventral segment of female twice the length of 

 preceding, posterior margin broadly, triangularly notched half 

 way to base, with an apical notch; lateral angles rounded. Male 

 valve broad, longer than last ventral segment, convexly sinuated, 

 slightly notched at apex; plates rather long, gradually narrowed 

 three-fourths their length, then produced with edges almost 

 parallel. Py gofers equalling plates, densely clothed with spines 

 apically. 



The species was described from Tennessee, and has been 

 taken in Kansas, Ohio and South Carolina. It occurs in Ten- 

 nessee in abundance, and will probably be reported for other 

 states when thorough collecting is done. Type in collection of 

 Mr. S. E. Crumb. 



Chlorotettix delta Ball. 



Chlorotettix delta Ball. Ent. News, 27, p. 205, 1916. 



cf Size and general appearance of tethys but with a much 

 larger head. Pale green with a slight tawny cast towards the tips 

 of the wings. Length, 4.5 mm. 



Vertex right angled, the margins straight, apex with the front 

 sharply conical, length very slightly less than the basal width, 

 nearly equalling the pronotum. Elytra long and narrow as in 

 lusoria, giving a trim, wedge-shaped appearance to the insect. 

 Venation distinct, regular, the nervures slightly raised.
