A single male specimen in the collection agrees with Osten 

 Sacken's description in Monographs, etc., iv, p. 294, in every 

 particular excepting that it possesses two supernumerary cross- 

 veins in the cell R^ (Comst.) proximad of the cross- vein of cell 

 Ri in the one \^ ing, and one supernumerary in the other.
