These two males from Mandera are in a better state of 

 preservation than the type, and therefore appear purer grey 

 on the fore wing. The only difierence I notice is in the ante- 

 and postmedial double lines being less fiUed-in with fuscous and 

 a little further apart below the apex of the cell than in the type 

 specimen, the only example hitherto known to us of this species. 

 The genitalia of one of Mr. Feather's specimens have been 

 examined ; they are identical with those of the type.
