114 Dr. G. B. Longstaff on 



rest on the leaves of the Acanthaceoiis under-shrub, 

 Isoglossa woodii, Clarke [= Edeinantluis origcmoidcs, T., 

 and of J. Medley Wood's Natal Plants, vol. i, plate 22], 

 called by the natives u-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 purplisli- 

 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 faitliful 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. IG. PJronia cleodora, $, 

 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 E. cleodora are Ccq^j^cj-is zcyheri, 

 Turcz, and NlclniJirrici 2^Qdunculosa, Hochst. 



Perhaps the most tropical-looking butterfly that we met 

 with in S. Africa was the large Nymphalid, Salamis 

 anacardii, L. ; nearly 4 inches across the wings, greenish- 

 Avhite, with a strong pearly lustre, it is a very beautiful 

 creature. Its flight is 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 

 anacardii, 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.
