34 SOUTH-AFRICAN 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 Katal (Fort Buckingham or Tunjumbili) early in March 1867. 

 It is quite a woodland butterfly, but seems to prefer forests at a considerable 

 elevation.^ I was struck with the resemblance Avhich living specimens, when 

 on the wing, bore to faded yellow leaves drifting before the breeze, and Mr. 

 J. P. Mansll 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 William's Town, expressed his belief that the 

 larva of Trimenia would be found to feed on Loranthus iDrunifolius, parasitic 

 on Schotia latifolia.

^ White, with black hind -marginal spots on nervures. Fore-iving : 

 base slightly irrorated with fuscous ; a hroad basal suffusion of orange- 

 red spreading over rather more than half of discoidal cell ; costa edged 

 with fuscous, which is widest (and white-scaled) near base, but very 

 narrow about middle of wing ; apex rather widely bordered with 

 fuscous ; four hind-marginal spots, of which the first sometimes joins 

 apical black, and the fourth (at end of first median nervule) is always 

 minute. Hind-ioing : base slightly fuscous ; a faint orange suffusion, 



1 Mr. Alfred D. Millar has sent me a (J taken near D'Urban on nth 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.
