Chlorotettix lusoria Osb. & Ball, Proc. la. Acad. Sci., 4, p. 226, (1899); Osb., Rept. 

 N. Y. State Ent., 20, p. 529, (1904); Wirtner, Hemp. W. Pa., (Car. Mus.) 3, 

 p. 225, (1904); Osb., Maine Agr. Exper. Sta. Bull., 238, p. 144, (1915). 



Form and general appearance of tergatus, but with a sharper 

 vertex and more general reddish cast. Length, 78 mm. ; 

 width, 2 mm. 



Vertex slightly convex, one-half longer on the middle than next 

 the eye, twice wider than long, margins broadly rounded, but with 

 a distinct, slightly produced tip ; front one-third longer than wide, 

 three times wider at ocelli than on clypeus. Pronotum long, sides 

 long, strongly rounding anteriorly, posterior margin nearly 

 truncate. Elytra long, greatly exceeding abdomen, without 

 appendix, first anti-apical cell long, parallel margined. 



Color: Similar to necopinus; vertex olive brown, with a faint 

 crescentiform band before the eyes; pronotum fulvous brown, 

 scutellum with a quadrate light area on the disc, including two 

 dark spots; elytra subhy aline with a distinct reddish tinge, 

 nervures light, below tawny yellow. 



Genitalia: Last ventral segment of the female long, emarginate 

 behind, with a strong, angularly pointed, dark margined, median 

 tooth half as long as the acutely rounding lateral angles. Male 

 valve short and broad, less than half the length of the preceding 

 segment; plates strong, flat, one-half longer than breadth at base, 

 outer margins thickened, sparsely hairy, points strongly divergent, 

 usually a fuscous line on either side arising from a spot at 

 the base. 



Type specimens (in Osborn collection) are from Ames, Iowa. 

 Besides these I have examined specimens from Ohio, New York, 

 New Jersey and Wisconsin. The species has also been reported 

 for Pennsylvania, New Hampshire, Colorado and Utah.
