specimen Bo, which, as I remarked before, showed very 

 well how imitator could have arisen from a mixture of 

 terra, hohleyi, and ohsntra. 

 '' IT. A trace of yellow suffusion on f.-w. inner margin (due to 

 terra). 

 "III. A diffusing of the h.-w. pale area, instead of its being 

 concentrated. I think Bg shows that the pale h.-w. 

 area of imitator was derived from obscura, tinted white 

 by hohleyi influence. 



" I much look forward to seeing the !Natal and West 

 African eurytus forms." 



Prof. PouLTON had examined the series of Ps. imitator, Trim., 

 in the Hope Department, viz. 35 specimens bred in 1910 by 

 the late Mr. A. D. Millar, and 3 females captured at North- 

 dene, Natal, in 1896. He agreed with Dr. Carpenter that Bg 

 could be easily transformed into imitator. With regard to I. 

 no trace of subapical yellow was seen in any of the white- 

 marked females. All the markings of the males and of a small 

 proportion of the females were pale yellowish white like the 

 males of Planema aganice, Hew., while the majority of the 

 females were white-marked like the female aganice. II. The 

 inner marginal marking was always present, yellowish in the 

 yellow-marked, grey in the white-marked specimens. III. 

 The bar crossing the hindwing was always well defined like 

 the model — sometimes, however, more band-like and straighter 

 along its outer edge, often, on the contrary, following the 

 contour of the hind margin of the wing and forming a quarter- 

 circle concentric with it, as in Planema aganice.

" I am sending you two more series of synepigonic Pseud- 

 acraeas with full data, and pupal skins of each specimen, also 

 a few leaves shoAving the curious way in which they are eaten 

 by the young larvae." 



Prof. PouLTON said that he had submitted the leaves to 

 Dr. 0. Stapf, F.R.S., of Kew, who had replied that they 

 agree very well with Sideroxylon brevipes, Baker, a Sapotaceous 

 plant well known in Uganda and allied to Chrysophyllum, a 

 food-plant of Pseudacraea ii^ the Lagos district and Natal. A
