133. Scirpophaga nivella Fabricius.

Fletcher (One Hundred Notes on Indian Insects, 1918) states that Scirpophaga 

 auriflua Zeller is a later name than S. xanthogastrella Walker, which name must 

 have preference. But S. xanthogastrella Walker is an entirely different species. 

 Hampson sinks S. auriflua to S. nivella Fabricius, and this we must accept for 

 the present.
