Proc. la. Acad. Sci., iv, 225, 1897. 



In general appearance resembling unicolor but usually a more 

 yellowish green, uniformly colored and without markings. Head 

 well rounded before. Female segment deeply excavated, bearing 

 a long spatulate process at the apex. Length 7 mm. 



Often found in company with unicolor, in grassy pastures and 

 meadows. It resembles so closely in size and color this species 

 that they are easily confused in the field.
