114 Dr. G. B. Longstaff on 
rest on the leaves of the Acanthaceous under-shrub, 
Isoglossa woodii, Clarke [= Ecteinanthus origanoides, T., 
and of J. Medley Wood’s Natal Plants, vol. i, plate 22], 
called by the natives w-Bomaan, which forms the bulk of 
the undergrowth of the scrub on The Bluff, at Durban. 
It hung more or less downwards with its wings closely shut 
up, in which position its general shape was not unlike that 
of a leaf, while its colour, yellow blotched with purplish- 
brown, had a striking resemblance to the many yellow, 
eaten and blotched leaves upon the shrubs. The brilliant 
insect lost itself in its surroundings, although this was not 
a case of definite leaf mimicry as in Kallima or even 
in Precis. A rough-coloured sketch made at the time 
gives (apart from artistic shortcomings) a faithful repre- 
sentation of some of the leaves, though the yellow colour 
hardly shows by artificial light. [Sketch and butterflies 
exhibited. ] 
Dr. Dixey has a note which confirms the above :— 
The Bluff, Durban, Aug. 16. Hronia cleodora, 2, 
observed to settle near leaves which, turned yellow 
and showing slits and circular holes, closely 
resembled its under surface. 
Mr. J. Medley Wood, the Director of the Natal Botanic 
Gardens, kindly writing to give me the name of the plant, 
says that the food plants of Z. cleodora are Capparis zeyheri, 
Turez, and Niebuhrria pedunculosa, Hochst. 
Perhaps the most tropical-looking butterfly that we met 
with in §. Africa was the large Nymphalid, Salamis 
anacardii, L.; nearly 4 inches across the wings, greenish- 
white, with a strong pearly lustre, it is a very beautiful 
creature. Its flight 1s very weak. Mr. A. D. Millar of 
Durban said that it was fond of resting in a particular tree 
or shrub with glaucous leaves. 
Dr. Dixey has a note :— 
Sydenham, Durban, Aug. 15. Watched Salamis 
anacardu, L. It flew in a slow, flappy, undecided 
way from side to side of the road, settling each 
time for a second or two on a tree. Presently it 
reached a tree whose leaves were about the same 
size as the anacardii when resting with wings over 
its back. Here it settled, beneath a cluster of 
leaves, being fully exposed to view and yet well 
concealed. It remained quiescent until forcibly 
disturbed.
