plates broad basally, suddenly constricted beyond middle and then pro- 

 duced to the slightly divergent tips, exceeded by the blunt and spiny 

 pygofers. 



Distribution: Specimens of this species have been taken 

 only from Cherokee county.

Form: Length, 6 to 7 mm. Vertex slightly longer on the middle than 

 next the eye, over twice as wide as long, broadly rounding with front. 

 Pronotum twice as wide as long, posterior margin distinctly emarginate, 

 short lateral margins rounding with humeral margins, disc transversely 

 wrinkled. Elytra rather broad, greatly exceeding abdomen, venation 

 weak. 



Color: Uniformly greenish or yellowish-green. 



External genitalia: Female, last ventral segment one-half longer than 

 the preceding, posterior margin broadly notched nearly three-fourths of 

 the distance to the base, the notch with a median spatulate process over 

 one-half the length of the notch; pygofers long and narrow, exceeding 

 the ovipositor, sparsely spined. Male, valve broad, longer than last ven- 

 tral segment, obtusely rounded apically; plates about three times as long 

 as the valve, broad basally, convex, spiny margins tapering to the sub- 

 acute apices, which are exceeded by the bristly pygofers. 



Internal male genitalia: Styles with large anterior curving process 

 and very broad at point of attachment to connective, then tapering rather 

 gradually till terminal fourth, when they are suddenly narrowed to long 

 and slender apical portion; connective Y-shaped, the stem also some- 

 what divided apically; oedagus long and curving, dividing into two 

 branches apically, which in turn divide again, there being thus four 

 slender curving and acutely-tipped terminal processes, the inner pair of 

 which are longer than the outer.
