 After the meeting he had sent a print of the negative to 

 Lt.-Col. R. S. Wilson, Governor of the Western Desert Province 

 of Egypt, and had asked him if he remembered whether the 

 two butterflies flew together in the Nuba Mountains Province. 

 Col. Wilson replied as follows : — 



" Mersa Mntruh, Egypt, 



"7.ii.l920. 



"Many thanks for your letter of ll.xii.1919 and for the 

 photos of the Charaxes enclosed therein. Yes, the viola 9 

 form of etkeocles flies with the epijasius, and is almost indis- 

 tinguishable from it on the wing except for its smaller size. 

 I was out with Capt. Kent Lemon at Talodi when I took my 

 first specimen of the former butterfly, and we both thought 

 it was an epijasius until it was netted. Afterwards it was 

 possible to distinguish it with care when on the wing, owing 

 to the difference in size. We both took several epijasius 

 round the same tree that day, and later, on several occasions, 

 took them together. The tree particularly favoured was 

 called Arrada (plur. Arrad) locally, viz. Albizzia amara, Boirin. 

 The ' Catalogue of Sudan Flowering Plants,' by A. F. Brown, 

 describes it as a large tree with strong timber. It is thorn- 

 less, loses its leaves in the dry season, and flowers March to 

 May. Its flowers are like those of Mimosa, but white instead 

 of yellow. It seeds very freely, and the seed-pods are fiat 

 and broad. It belongs to the Mimosa group of the Legti- 

 minosae. All the Charaxes I took in the Nuba Mountains 

 Prov. are partial to it, viz. varanes, epijasius, and etheodes. 

 C. varanes when hanging downwards from a twig with 

 closed wings is extraordinarily like a partially broken and 

 dry seed-pod (which is then reddish brown) both in colour 

 and pattern, the small circular markings on the underside 

 of the butterfly looking like the seeds which show through 

 the constricted parts of the pods where they lie."
