Form: Smaller than viridis. Pronotum obtusely angled and with very 

 distinct striations. 



Color: Deeper green than viridis. Males slightly fuscous and in both 

 cases the subhyaline elytra slightly brownish. Differs from other green 

 forms in lacking the black spot on the propleurae in both sexes. 



External genitalia: Characteristic of the genus. 



Distribution: Found so far only in Hamilton county, but 

 likely occurs in eastern portions of the state as well, for speci- 

 mens have been taken at Kansas City, Mo. 



Hosts: Honey locust. 



Genus ONCOPSIS Burm. 



Like Macropsis, the members of this genus have the pro- 

 notum angularly produced beyond the anterior margin of the 

 eyes, but the pronotum differs in being rather more reticulate 

 than striate and with the reticulations running more trans- 

 versely than obliquely. The pronotum is short and deeply con- 

 cave posteriorly, with the lateral margins very short. 



A single species of this genus has been taken in Kansas.

Form: A short robust species. Length, 4 to 4.5 mm. Vertex very 

 short, posterior margin raised up from pronotum which is not as sharply 

 angled as in Macropsis. Pronotum very deeply reticulate and scutellum 

 somewhat less so. Elytra greatly exceeding abdomen and characterized 

 by having only two anteapical cells and four apical cells. 



Color: Vertex, pronotum and scutellum usually greenish, sometimes 

 brownish, and usually pitted with black, the scutellum with triangular 

 dark spots on basal angles. In light forms these black pits and spots may 

 be absent. In typical and dark forms the elytra are quite dark across the 

 base, have a dark band across tip of clavus and the apex darkened. In 

 light specimens the elytra are gray with the dark spot at tip of clavus, 

 cephalad of which appears a light area.
