Pscudaeraea euryhis hohleyi. 91 



According to Eltriiigham's " African Mimetic Butterflies " 

 the typical aganice, in which the male is paler and the 

 female has the white areas of smaller extent, is " confined 

 to the Natal region, and is represented in British and 

 German East Africa by the variety montana, which has 

 a much wider range, being common in the Belgian Congo." 



An interesting point is that in 1914 when visiting a 

 group of islands east of Kome (Wema, etc.) this Planema 

 was not noticed there. 



But in 1919 when revisiting all the islands I had been 

 to in '14, I found aganice on the Wema group. I am quite 

 inclined to think that it had arrived there since 1914. 



The (^ of Planema alcinoe sometimes shows strong 

 suffusion of the brown near the base of the fore-wing by 

 a dusky hue. If this were accentuated a distinct approach 

 to the pattern of the ^ aganice montana would be produced. 

 This point requires further investigation. 



A very interesting member of Combination II is. the 

 large black-and-white Hypsid moth Deilemera acraeina 

 H. H. Druce. This occurs at Entebbe, but I had never 

 found it until I collected at Kakindu, so that it does not 

 seem to have made its way to the islands. It was noted 

 in my journal that " I saw it on the wing and took it for 

 another $ Papilio cynorfa Fabr., but reahsed after a little 

 that there was something different. Its flight was not 

 like that of any Hypsid I have seen before; much more 

 floating and hke that of the Papilio." P. cynorta $ is 

 black and white, mimicking the $ Planema ejmea of the 

 west coast, which shows minor differences in its pattern 

 from the Planema models of Combination II. 



Another member of Group II, the black-and-white form 

 of the Satyrine Elymmas pliegea, which is not common at 

 Entebbe, has never been met with on an island, nor at 

 Kakindu. 



Combination III. — The model, Planema epaea Grose-Sm., 

 in its eastern form piaragea was not taken on any of the 

 islands discussed in this paper, although it occurs on 

 Damba, which, as has been said, lies only a few lumdred 

 yards away from the eastern end of Kome. But several 

 were taken at Kakindu, showing considerable variation. 

 It is very interesting that at Kakindu Papilio cynorta, 

 which was very abundant, was entirely of the western 

 form, whose female mimics the black-and-white western 

 form of Planema ejxiea which was not seen at Kakindu,
