 extending from costa (at stigma) to inner end of discal cell. 

 Auxiliary vein opposite or somewhat beyond inner end of second 

 sub-marginal cell, sub-costal cross-vein near its tip ; marginal 

 cross-vein indistinct, about its length distant from tip of first 

 longitudinal vein and opposite middle of anterior branch of second 

 longitudinal vein ; prsefurca arcuated at the base, moderately 

 long ; petiole of first sub-marginal cell very short, rather longer 

 than marginal cross- vein ; anterior branch of second longitudinal 

 vein arcuated at the base, somewhat sinuated^ usually less than 

 half the length of posterior branch, joining costa beyond tip of 

 first longitudinal a distance about equal to length of great cross- 

 vein ; posterior branch slightly arcuated upwards at extreme tip ; 

 second posterior cell more than half the length of third ; discal 

 cell longer than wide, the great cross-vein situated before its 

 middle; sixth longitudinal vein slightly and seventh distinctly

Sab. — New South Wales (Masters and Skuse). Five 

 specimens.
