 Thamnotettix longulus Van D., Cat. Hemip. N. A., p. 6880, 1917. 



Form: Quite elongate. Length, 5 to 6 mm. Vertex more produced 

 than in preceding species, being distinctly longer on middle than next the 

 eye, twice as wide as long, sloping, and rounding obtusely with front. 

 Pronotum long, scarcely twice as broad as long, strongly convex an- 

 teriorly, slightly emarginate posteriorly, lateral margins nearly as long 

 as the humeral. Elytra very long and narrow. 



Color: Nearly unicolorously fulvous, marked with brown. Vertex ful- 

 vous, white ocelli connected by light band, with median longitudinal line 

 and two basal spots, darker. Pronotum irregularly mottled with darker 

 spots anteriorly. Scutellum with basal angles and two spots on disc 

 darker than the fulvous background. Elytra light fulvous, nervures 

 lighter, some of them tending to be darker margined. Face marked with 

 brown arcs. 



External genitalia: Female, last ventral segment twice as long as the 

 preceding, narrowed posteriorly, the posterior margin angularly emargi- 

 nate one-third the length of the segment, slightly elevated; pygofers long 

 and narrow, slightly exceeded by ovipositor, bearing many long bristles 

 on posterior half. Male, last ventral segment two-thirds the length of 

 the preceding, valve broad, triangular, obtuse at apex; plates broad 

 basally and long, spiny margins tapering somewhat concavely to the 

 acute tips which nearly equal the long-bristled pygofers. 



Interrial mule genitalia: Styles very broad anteriorly due to large an- 

 terior processes and large processes to the connective, with a very defi- 

 nite lateral incision apically, leaving a large outwardly curving apical 

 tooth which has its outer margin quite rough with small teeth ; connective 

 large, deeply bifid anteriorly, slightly so apically; cedagus broad basally, 

 with a small basal and dorsal process, then gradually tapering till it 

 divides into two long, apical, acutely-pointed processes. 



Distribution: This species has been taken only in Cherokee 

 and Douglas counties. 



Hosts: DeLong reports this species as abundant on grasses.

Form: Long and narrow. Length, 4.75 to 5.5 mm. Vertex distinctly 

 produced, half longer on middle than next the eye, flattened, subacute 

 apically. Pronotum long, not twice as broad as long, humeral margins a 

 little longer than lateral, posterior margin slightly emarginate. Elytra 

 very long and narrow.
