Form: Somewhat narrower than viridis. Length, 5 to 6.25 mm. Ver- 

 tex in both sexes distinctly angularly produced, about three-fourths as 

 long as wide, concave, margins rather sharp. Pronotum characteristic 

 of the genus. Elytra long, exceeding the abdomen, frequently a black 

 spot at tip of clavus and another at tip of inner apical cell. 



Color: Yellowish-green. Elytra with greenish nervures and frequently 

 with brownish apices. Tip of ovipositor reddish. 



Exteryial genitalia: Female, last ventral segment very long, posterior 

 margin roundingly produced ; pygofers short, much exceeded by the 

 spiny-tipped ovipositor. Male, valve very small, triangular; plates broad 

 at base, spiny, lateral margins concavely tapering to long acute tips; 

 pygofers much exceeding plates and thickly covered with long spines. 



Dist7^ihution : Fairly common over the state, as shown by 

 the following map : 



Hosts: Taken on coarse grasses on low land.

 Parabolocratus brunneus Van D., Hemip. N. A., p. 626, 1917. 



Form: Smaller than other members of the genus. Length, female, 

 6 mm.; male, 3.5 to 4 mm. Vertex relatively shorter than in preceding 

 species, but in both sexes the margin is quite thick. The elytra may either 

 reach the last ventral abdominal seg-ment, or, in some females, cover 

 about two-thirds of the abdomen, the nervures always distinct.
