20 SYNOPSIS OF THE GENUS CHLOROTETTIX 



Color: Pale green, eyes dark, the usual indented arcuated line 

 on the pronotum. Apex of vertex and tips of elytra with traces 

 of tawny. 



Genitalia: Male valve short, obtusely rounding. Plates nar- 

 row appressed, equilaterally triangular, their apices produced as 

 minute slightly separated finger-like processes as long as the 

 plates and equalling the rather broad and foliaceous pygofers. 



This species was described from a single male specimen col- 

 lected in Arizona and is the only specimen that has been reported. 

 According to the original description this species, is easily recog- 

 nized by the conically pointed head and distinct genitalia.

Resembling C. vividus in shape, but slightly smaller and with 

 distinct genitalia. Length, 5 mm. Much smaller than any other 

 known northern species. 



Vertex obtusely angled, slightly more than one-half longer on 

 the middle than next the eye, twice as broad as long. Anterior 

 margin of pronotum strongly convex; posterior margin slightly 

 concave; lateral angles broadly rounded. Elytra smoky hyaline. 



Color: Resembling C. vividus in color, more of a grass green 

 than found in most species of the genus. Last ventral segment of 

 the female with a dark median stripe from the apex of the incision 

 to the base of the segment. Ovipositor dark. Tibia and tarsi of 

 front legs brownish. 



Genitalia: Female last ventral segment twice as long as pre- 

 ceding, lateral angles well rounded. A rather broad median 

 notch extending half way to the base ; sides convexly angled 

 posteriorly. Male valve twice as wide as long, triangular, with 

 rounded apex. Plates rather long, convexly rounded to rather 

 blunt tips. Hairs mostly on margin and dorsal surface. 



A pair were swept from grass in a clearing at Trout Lake, 

 Wisconsin, September 7, 1916. The species was described from 

 these specimens and no other records have been reported. Type 

 in the author's collection.
