This geuus is closely allied to Karaihura, the only structural difference of any value which 

 I can discover being in the length of the costal uervure of the anterior wings, which, as pointed 

 out in the generic synopsis {antea, p. 234), extends to about half the distance of the costal 

 margin. 



I have felt no hesitation in placing Satadra as a synonomy of ranchala, Mr. Moore, its 

 proposer and describer, stating that its " venation" is " similar to that of ranchala." 



It is, however, a question whether these four proposed genera, viz., Narathura, Nilasera, 

 Panchala, and Satadra, as formulated by Mr. Moore, and condensed into two by the present 

 writer, would not even be more naturally treated as one, under two sections. One feels a 

 reticence in altogether disagreeing with the conclusions of a veteran lepidopterist, but at the 

 same time how can this generic splitting advance the study of Entomology, which, after all, is 

 the only excuse for publication ? 



The geographical distribution of Pancliala has been noticed with that of Narathura.
