SYNOPSIS OF THE GENUS CHLOROTETTIX 9 



tinged with testaceous ; front marked with ten pale arcs, and two 

 spots at base of clypeus brown. Pronotum testaceous, pale before 

 and on the median line, either side of which is a brown cloud, and 

 a smaller one occupies each latero-posterior angle. Triangular 

 spots in basal angles of scutellum, and a median line with a spot 

 either side, brown. Elytra fuscous-brown, nervures white. Wings 

 smoky, irridescent, nervures brown. 



Genitalia: Last ventral segment of the female thin, broadly 

 and deeply cleft nearly to its base ; the incisure at its apex armed 

 with a small blunt tooth, the lateral lobes ovate. Male valve 

 almost twice as long as preceding segment, rounded and slightly 

 emarginate on either side; plates broad at base, suddenly con- 

 stricted behind middle, then produced, tips slightly divergent. 

 Pygofers large, fitting at apex to form an oval opening. 



The species is typically southern, and was described from 

 specimens collected in Mississippi. In addition to this state, it 

 has been reported from Tennessee, Kansas, Florida and North 

 and South Carolina. I have examined specimens from Tennessee 

 and North Carolina.

Resembling spatulatus, but with a broader vertex. Green 

 with a red band on the margin of the vertex. Length 7 mm. 



Vertex broadly obtusely rounding, but little longer on middle 

 than next the eye, two and one-half times wider than long, evenly 

 rounding to front. Elytra rather long, the veins large and distinct. 



Color: Pale green, a transverse red band on margin of vertex 

 and front, sometimes becoming pale orange and often extending 

 over the eyes. The elytra of the male usually tinged with tawny 

 brown. 



Genitalia: Last ventral segment of female deeply, triangularly 

 excavated, with a strap-shaped tooth similar to that in spat- 

 ulatus. Male valve nearly as wide as the preceding segment, and 

 about half as long ; plates nearly flat, long, triangular, the margins 

 sparsely haired.
