 with a clear brownish-black tint, the base and the costal cell being 

 yellowish-brown ; cross- veins very lightly margined with fuscous. 

 Wing-veins as in E. batrachoides, but the first posterior cell broadly 

 open and the vein dividing the discal from the third posterior cell 

 less sinuous.
