SOUTH-AFEICAIS' BUTTERFLIES. 
Mr. W. S. M. D'Urban first brought this beautiful species to my notice, 
forwarding specimens taken near King William's Town in i860. Colonel 
Bowker subsequently met with it in the Trans-Kei ; and I had the pleasure of 
observing it in ISTatal (Fort Buckingham or Tunjumbili) early in March 1867. 
It is quite a woodland butterfly, but seems to prefer forests at a considerable 
elevation.^ I w^as struck with the resemblance which living specimens, when 
on the wing, bore to faded yellow leaves drifting before the breeze, and Mr. 
J. P. Mansel Weale, writing to me in the same year, independently recorded 
the same impression, conveyed to him by the notice of examples occurring in 
the woods near Bedford in the Cape Colony. In 1877, Mr. Weale, writing 
from Breidbach, near King AVilliam's Town, expressed his belief that the 
larva of Trimenia would be found to feed on Loranthus lorunifolius, parasitic 
on Schotia latifolia.

narrow about middle of wing ; apex rather widely bordered with

1 Mr. Alfred D. Millar has sent me a taken near D'Urban on iith September 1887, 
and informs me that he met with five others during that month, but that the species is rare 
both in that vicinity and about Pinetown.
