Geographical Distribution of Acraea lycoa, A. johnstoni. 7 



The specific identity of all the forms of A. Johnstoni 

 would, I think, with the exception of the toruna form, be 

 quite satisfactorily established on the external features, 

 but apart from my own examination of the genitalia, we 

 have still further direct proof In the Tring Museum 

 there is a family oi A. johnstoni bred from ova at Nguelo, 

 Usambara. To which variety the parent belonged I have 

 been unable to ascertain, but the nine offspring consist of 

 the following : — 



Three examples of the type form ( = semifulvescens), two 

 males and one female. The latter is shown at Plate I, 

 fig, 12. The males are slightly smaller, and have the 

 hindwing patch very faintly ochreous, and one has the 

 forewing spots much paler. 



Four examples of the fulvescens form, two males and 

 two females. One of the latter is shown at Plate I, 

 fig. 11, The males resemble this female, but the remain- 

 ing female is somewhat intermediate, having the spots 

 paler, and a considerable powdering of black scales at 

 the base of the wings and about the inner angle of the 

 hindwings. 



One black and white female shown at Plate I, fig. 13. 

 This form occurs very commonly at Ghirinda, and I have 

 also seen a similar specimen from Mombasa. 



One male shown at Plate I, fig. 14. This example 

 is nearest to the commonest variety of the species ( = 

 confusa). 



Acraea toruna, Grose-Smith. 



We may now consider the position of Acrca toruna in 

 relation to the foregoing species. The ground-colour, 

 especially in the foi'ewings, is more profoundly modified 

 than in any of the other forms. Whilst the present 

 position of the forewing spots may be traced from 

 johnstoni f confusa through the typical male johnstoni, 

 the distal outline of the hindwing patch is much less 

 angnlated than in other johnstoni forms, at least on the 

 upperside, a fact doubtless due to the close approximation 

 of its pattern to that of its model Planema latifasciata. 

 One feature stands out prominently, the palpi are nearly 

 always entirely black,* whereas in all the forms oi johnstoni 



* I have to tliank my friend, ]\Ir. F. A. Heron, for first calling my 

 attention to this feature. It is interesting to note that the genus 

 Planema is distinguished by tlie possession of black palpi, though 

 there is also in that genus a white lateral streak.
