" Mr. Green is of opinion that both forms occur in practically 

 equal numbers througbout the year, and he has given the 

 following record of some gatherings of wahlhergi that he has 

 witnessed. 



" ' Mr. Harold Millar told me to-day that he saw, towards 

 sundown, a large batch at Isipingo last August (before the 

 15th). He was out buck-shooting and so could not capture 

 any. The butterflies were apparently newly emerged, settled 

 in little groups under the leaves of bushes. Both forms were 

 represented and in about equal numbers. The food-plant 

 was near, and larvae were seen. I mention this all fully, as 

 it does not seem to be an assemblage of the same character 

 as that mentioned by Mr. Green, comprising wahlhergi only.' " 



Mr. H. A. Green, of 168 Point Eoad, Durban, kindly supplied 

 the following information upon the habits of wahlhergi and 

 mima. His observations were made in the Durban district, 

 and the note is dated March 31, 1914. 



" As far as my observations regarding predominance of 

 either form, during the seasons in which they appear, have 

 carried me, I can only say that tvahlhergi, being far more con- 

 spicuous, is apparently the more numerous. Mima, owing 

 to its greater resemblance to such species as Papilio hrasidas, 

 the cenea $ of P. dardanus [and their Danaine models], is not 

 so noticeable, but I have taken them in almost equal numbers. 

 I may mention regarding E. wahlhergi that sometimes on the 

 Bluff when out collecting, I have seen them congregate in 

 large numbers on one tree, sometimes as many as twenty or 

 thirty sunning themselves together. On one occasion out 

 of curiosity I tried to see how many could be taken in 

 one sweep of the net, and I captured ten. Mima I have 

 never seen congregate in this way." 



The assemblages recorded by Mr. Guy A. K. Marshall 

 (Trans. Ent. Soc, 1902, pp. 491, 492) contained both forms 

 as shown in an exhibition to the Entomological Society in 

 1906 (Proceedings, pp. liii, liv). In conclusion Prof. Poulton 

 hoped that it would soon be possible to breed either the 

 eastern or the western Eiiralias through some generations 

 and thus settle finally the Mendelian relationships. It was 

 all the more necessary that this should be accomplished
