great predecessor had not only ceased to be an opponent, but 

 was teaching the very conclusions he had at first disbelieved. 



" Among the lepidopterists with whom I have the pleasure 

 to be acquainted, I think the most uncompromising opponent of 

 my view of this matter was my friend Mr. Hewitson ; — though 

 I must say that our distinguished President, Professor Westwood, 

 was almost as resolute in his unbelief. I am not aware that 

 the latter published anything on the subject. . . ." ^ 



The following drawer contains specimens of cenea from 

 Natal, where the same female forms as those of Cape Colony are 

 found, together with the peculiar ancestral form leighi. 



The last series of drawers I have the pleasure of showing you 

 contains the fine synepigonic groups which I owe to the energy 

 and ability of G. F. Leigh, F.E.S., of Durban. All these have 

 been bred by ]\Ir. Leigh from females captured at Durban, or 

 in the Durban district. 



The first two families were bred from hippocoon females, and 

 they show an extraordinary contrast. The first,- bred in 1906, 

 contains 14 males, and the following females — 3 hippocoon, 3 

 trophonius, 3 cenea with white, 5 with more or less ^'■ellow marks 

 on the forewing. The parent of this family, together with one 

 of its male offspring, and each of the four female forms with 

 its Danaine model, is represented in the accompanying Plate L 

 The second family,^ bred in 1907, contains 16 males, while of the 

 13 females all are cenca, and not a single one like the parent. 



We now pass to families bred from tropJwnius parents, of 

 which there are 3. The first, ^ bred in 1903, contains only 3 

 males, and 2 cenea females. The second,^ bred in 1904, from a 

 tropiionins parent which unfortunately escaped, contains 6 males, 

 I trophonius, and 5 cenea. It is interesting to note that the rich 

 fulvous colouring of the trophonius parent has produced a distinct 

 effect upon the hindwing patch of one of the cenea oñspring. 

 The third family,^ bred in 1910, is both large and remarkable,
