 submarginal cell is but little more distal than that of the second pos- 

 terior. — One male, two females. 



NB. This species can only be compared to fumipennis Wk., 

 fusca Wk., and lugens Wk. But the former is said to have a „cu- 

 preous black" abdomen, lugens black femora, except at the base, and 

 fusca altogether black legs.
