 except radial ; hind-marginal border narrower than in fore-wing, but

In a few $ individuals I have found tlie disco-cellular yellow-ochreous ray

I met with this remarkable little butterfly in Natal in March and April 

 1867, but only in two localities, viz., on the Intzutze in the Great Noodsberg, 

 and at the Umgeni Falls near Maritzburg. On each occasion there were a few 

 specimens only, flitting slowly about the grass and herbage on the side of a 

 ravine, and constantly settling on the stems of grasses. As noted in my 

 Ehojxdocera Africce Australia, Mr. D'Urban noted quite similar habits of the 

 insect in British Kaffraria as long ago as 1861 ; while on the Bashee, Colonel 

 Bowker observed that the butterfly was fond of settling on the ground or on 

 small stones. The last-named gentleman took many specimens in Napoleon 

 Valley, Zululand, in 1880.
