Pronotum only a little longer in the middle than across the humera 

 angle, rugae obscure. Pronotum, scutellum, costal margin of elytra, 

 face and below, green, rest of the elytra and the basal angles of scutel- 

 lum washed with brown, which is deepened on the base of the clavus 

 into a more or less definite brownish fuscous band margining the 

 scutellum ; pygofers yellowish, green at tip ; propleura unmarked. 



Habitat, Canada, Iowa, Colorado. Occurs on cottonwood at Ames. 

 This is a very distinct species on account of its broad, short vertex 

 and large size. The male is not known. The difference in color 

 seems to be due to localizations of the pigment ; as the band becomes 

 darker the brown disappears from the central part of the elytra.

Bright saffron yellow, elytra clouded with brown, deepest on the 

 clavus. Length, 9 5 mm.: width, 1.50 mm.; males smaller. 



Pronotum obtusely angled before, much elevated behind, rugae 

 coarse and distinct either side a median raised line. Face and pro- 

 notum bright saffron yellow; scutellum light yellow, the angles some- 

 times clouded with brown; elytra deep brown on the disc, fading to a 

 broad yellowish costal margin, a saffron yellow line along the scutel- 

 lar and humeral margins. Below light yellow, propleura unmarked. 



Habitat, Lexington, Kentucky, on honey locust (Garman). This 

 is quite distinct in all the specimens examined, the saffron yellow 

 color remaining very constant and at once separating it from related 

 forms.
