1900, p. 479, pi. xii, fig. 6. It is defined by the "' band and 

 spots " of the upper surface being " pale blue except the 

 upper postdiscal spots," which are generally white as in 2 

 form a, but sometimes buff as in b, or blue though paler than 

 the rest of the markings. The admarginal spots of the H.W. 

 upper surface are dull red above, olive green below (viz. 

 towards the anal angle). Now that this form is so much 

 better understood, its mimetic relations clear and genetic 

 relations partly so, it is convenient that it should be named, 

 and I propose to dedicate it to the naturalist to whom we 

 owe nearly the whole of our knowledge on the subject. 



Tvpe in Hope Department : one of the females (with white 

 upper post-discal F.W. spots) which emerged Dec. 13-14, 

 1917, of the family recorded on p. lxxxi. Chirinda, S.E. 

 llhodesia. 



Within the limited area of Chirinda forest in S.E. Rhodesia 

 the males of this species of ( 'haraxes are accompanied by 

 females of the form rosae, But!., mimicking the females of 

 CJi. dihaeron, Feld., one of the dominant larger species in 

 the forest, by swynnertoni females, mimicking the males of 

 dihaeron, and by the usual female found wherever ethalion 

 occurs, i.e. the 2 f. ethalion which probably mimics another 

 large species, Ch. brutus, Cr. Inasmuch as rosae has been, in 

 other localities, accepted as a female form of etheocles the 

 question arose as to whether the Chirinda forest harboured 

 this species or ethalion, or a mixture of the two. Dr. Jordan 

 therefore kindly examined the armature of 4 males and found 

 all to be ethalion . rendering it highly probable although not 

 certain that at Chirinda the rosae 2 f. belongs to this species.* 

 .Mr. Swynnerton's two families bred from known females do 

 not throw any light on this question, although they prove 

 that ethiil ion and swynnertoni belong to the same species and 

 render it nearly certain that the relationship between them 



* Since the above paragraph was written, Mr. H. Dollman has 

 exhibited, Dec. 4, 1918, bred specimens of the manica, Trim., and 

 pha us, Butl., females, from N. Rhodesia, and has proved thai these 

 Forms, both hitherto regarded as etheocles, belong to distinct specie 

 I believe that the genitalia of the accompanying males will show that 

 manica is <ilmlii.ii and that phaeus is etheocles. If this lie c nfirmed 

 there can he liitle doubt thai rosai . which resembles manica, is also 

 a form <.f ethalion. E. I'.. I'.. Doc. 28, l'Hs.
