Funkhouser gives the following technical (iescription : 



Fine large species, brilliant green, slowly fading to yellowish in dried 

 material; metopidium perpendicular; dorsal crest high and arcuate; posterior 

 process slender and curving downward; tegniina and wings entirely hj'aline; 

 upper parts of femora often marked with black. 



Head broad, nearly smooth, very finely and faintly punctate, longitudinally 

 striate; eyes prominent, subtriangular, very dark bordered with white, ex- 

 tending beyond adjoining lateral margins of pronotum; ocelli prominent, 

 brownish, nearer to each other than to the eyes; inferior margins of vertex 

 broadly sinuate; clypeiis broad, sparingly pubescent, median lobe of apex 

 extending below lateral lobes. 



Pronotum densely and coarsely but not deeply punctured ; metopidium con- 

 vex, median carina distinct but irregular; sides of metopidium meeting be- 

 fore middle of body; lateral semicircular impression deep; posterior process 

 long, slender, gradually acuminate, curving downward, extending beyond abdo- 

 men and reaching about halfway from internal angles to apices of tegmina. 



Tegmina entirely hyaline, slightly wrinkled, bases greenish and lightly 

 punctured. Undersurface of body j'ellowish; segments of abdomen in some 

 cases bordered with black; notch of last ventral segment of female broadlj^ 

 angular. Femora often marked with black above; tarsi ferruginous. 



Length to tips of tegmina, 9 mm.; width between humeral angles, 4 mm. 



Internal male genitalia. Styles large anci stout, the anterior por- 

 tion long and wicie, the posterior part curving to the truncate anci 

 serrate tips, which vary from nearly transversely truncate to quite 

 obliquely truncate, the apex in the latter case being quite pro- 

 nounced, the posterior fourth with two rows of very long hairs, the 

 outer row being longer; connective short, widest just behind the 

 middle, usually pentagonal in shape; oedagus, viewed laterally, 

 much as in Ceresa, the dorsal process varying in width and with a 

 small to a very pronounced hump, but with no projection to the 

 connective, ventral process moderately stout, slightly concave on 

 ventral side preapically, the functional orifice occupying nearly half 

 its length medially. 



Distribution. This species is found throughout the United States
