 translucent, with a dusky tapering spot on the middle, the veins pale, cuneus a little dusky on 

 the inner border ; membrane very long, dusky, with the veins pale yellow. 



Length to end of abdomen 4 mm. To tip of membrane 6 mm. Width of pronotum 1.33 mm. 

 Described from three specimens from Colorado. It is notable for the extreme length of the 

 wing-covers."
