The original description as given by Fitch is very short and is 

 quoted here: "Sordid green, immaculate; elytra smoky; tergum 

 black; beneath greenish yellow; tarsi pale brown. Length 0.30. 

 On willows." 



This species can be best separated from the others of the 

 genus by a more detailed description. It resembles unicolor in 

 form and size, large, robust, but with head narrower, and a 

 uniform dark fulvous green color. Length, 7 mm. 



Vertex a little more 'than twice as wide as long, slightly longer 

 on the middle than next the eye; anterior margin somewhat 

 produced, obtusely rounded. Front a little longer than broad, 

 cheeks narrow, clypeus almost rectangular. 



Color: Almost uniform sordid green; front, pronotum and 

 scutellum often marked with yellowish green. Elytra smoky, 

 abdomen and dorsal surface black, beneath pale yellow. 



Genitalia: Last ventral segment of female twice as long as 

 preceding, posterior margin with a broad, V-shaped notch extend- 

 ing half way to the base, lateral lobes rounded; py gofers long, 

 almost equaling the ovipositor. Male valve triangular, apex 

 obtusely rounded, sides somewhat concave near base. Plates 

 large, broad, covering py gofers, sides slightly sinuated, apices 

 broad and obtuse; margins armed with short spines and a fringe 

 of soft white hairs. Pygofers produced superiorly in a prominent 

 angle, and below in a curved appendage enclosing the styles. 



Specimens are at hand which were collected at Fitch's home by 

 Prof. Osborn and have been compared with the Fitch types in 

 Albany. I have also examined specimens from Michigan, Ohio, 

 Tennessee, Wisconsin, Illinois, New Jersey and South Carolina.
