Explanation of Plate XXVII. 



Fig. 5. Jlypolimnas (Euralia) kirhyi : Jilore, Sabake Eiver, about 

 200 ft, about 80 miles N. of Mombasa : July 14, 1906. 

 The extraordinarily close resemblance between this and 

 the next species is probably explained by arrested diverg- 

 ence as in many mimetic groups. 



Fig. 6. Hypolimnas (Euralia) deceptor: Giryama country, 5-700 ft., 

 about 45 miles N. of Rabai : July 20, 1906. The mark- 

 ings of this sjiecie?, being larger than in kirhyi, produce a 

 closer likeness to ochlea, compensated by the more 

 prominent submarginal markings of the hind-wing. The 

 curved marking of the fore-wing probably exhibits in 

 both species the influence of the Pseudacrsea (Fig. 4).
