 Macropsis suturalis Van D., Cat. Hemip. N. A., p. 583, 1917. 



Form: A large species. Length, 6 mm. Vertex and pronotum obtusely 

 angled, the latter with the striations not as distinct as in preceding 

 species. Elytra long and slender. 



Color: Green all over except for dark brown lines starting on pronotum 

 behind the eyes, including all the clavus, extending beyond clavus at 

 about their distal half and continuing, as a narrow stripe, to tip of 

 elytra. 



External genitalia: Female, last ventral segment as in trimaculata 

 but proportionately larger; pygofers very long and narrow, slightly ex- 

 ceeded by tip of ovipositor. Male, last ventral segment broad, slightly 

 emarginate posteriorly; plates long and narrow, much exceeding the 

 short but broad pygofers. 



Distribution: Taken in Ottawa and Pottawatomie counties. 

 Hosts: Occurs in both counties on Salix amygdaloides.

 Macropsis crocea Van D., Oat. Hemip. N. A., p. 583, 1917. 



Form: Stout. Length, 4 to 5.5 mm. Vertex and pronotum obtusely 

 angled. Pronotum coarsely striated, posterior margin deeply concave, 

 almost parallel with anterior margin. Elytra long and usually somewhat 

 spread apart at tip. 



Color: Yellow, but with elytra, especially clavus, clouded with brown. 



External genitalia,: Female, last ventral segment characteristic of the 

 genus; pygofers long and narrow, exceeded by ovipositor. Male, last 

 ventral segment over twice as broad as long; valve appearing to be short 

 and triangular; plates long, narrow and flattened, exceeding the short, 

 broad and truncate pygofers. 



Distribution: This form has not yet been reported from 

 Kansas. 



Hosts: The types were taken on honey locust.

Form: A large, stout species, larger than other green species of this 

 genus. Length, 5 to 5.75 mm. Vertex and pronotum more acutely pointed 

 than in most members of the genus. Striations of pronotum distinct, but 

 rather fine.
