PLATE VI 



Models. 



Fig. I. Acraea egina, Cram, . Entebbe. Also 

 occurs as far north and west as Sierra Leone. 



Fig. 2. Acraea egina, j. Sierra Leone. 



Fig. 3. Acraea zeies acara,'H.ew. . NataL The 

 example figured is below the average in size. 



Fig. 6. Acraea zetes acara, 5. Chirinda. From 

 an example in the Hope Department. 



Fig. II. Acraea orina, Hew. o^. Sesse Island, 

 Victoria Nyanza. Extends also to West Africa. The 

 sexes are similar. 



Fig. 12. Crenis pechueli, Dewitz, o^. Alala 

 Plateau, North-West Rhodesia. From an example in 

 the Hope Department. 



Fig. 13. Planema vestalis, Feld. 5. Sierra Leone. 

 Both sexes are rather variable in depth and brilliancy 

 of colour. 



Mimics. 



Fig. 4. Pseudacraea boisduvali, Doubl. a^. Ra- 

 ketta River, Freetown. 



Fig. 7. Papilio ridleyanus, White, . Entebbe. 

 The sexes are similar, and the species has a range 

 corresponding to that oi A. egina. 



Fig. 5. Pseudacraea boisduvali,^. Raketta River. 

 The resemblance to the 5 egina is not so marked as 

 that between the respective o^cr^. (See text.) 



Fig. 10. Pseudacraea boisduvali irimeni, But\. . 

 Natal. An example of the white suffused form. 



Fig. 8. Pseudacraea boisduvali irimeni,ci^. Natal. 

 A richly-coloured example lacking the white suffusion. 



Fig. g. Pseudacraea boisduvali trimeni, 5. Chi- 

 rinda. From an example in the Hope Department. 

 The white suffusion is of a crude and chalky appear- 

 ance in this specimen. As in the model, this feature is 

 variable. 



Fig. 14. Pseudacraea clarki, Butl. a^. Though 

 particularly resembling orina, both species may be 

 considered as synaposematic with egina. 



Fig. 15. Crenidomimas concordia, Hopff. 0^. 

 Mporokoso, North-East Rhodesia. From an example 

 in the Hope Department. The $$ of both model and 

 mimic are darker, and show perhaps a still closer 

 resemblance. 



Fig. 16. Pseudacraea striata, Butl. 5. Sierra 

 Leone.
