Although the description states that the discal cell is small and 

 apically very oblique, the type shows it to be of other conformation. 

 The contact with the second posterior cell is quite broad. Hence 

 taos turns out to be closely allied. The first and second posterior 

 cells are of almost equal width at their proximal end. The first sec- 

 tion of the front border of the discal cell is slightly over one third 

 the length of the second section. The thorax is olivaceous except a 

 median cinereous stripe between the two black vittse. The stigmal 

 darkening is scarcely visible.
