Dx, H. Eltringham on 



this as a good species, it remains only to deal with 

 masamba and siliana. 



M. Oberthur expresses his regret at having sent speci- 

 mens labelled as silda, which do not precisely agree with 

 Mabille's silia, and which he now refers to his new species 

 siliana. Professor Houlbert has examined the male and 

 female genitalia and also some of the wing scales, and the 

 specific rank of siliana is claimed on the following points. 



H. -w. border upper- 

 side 



F. -w. inner margin 



Papilla on which 

 occurs external 

 orifice of bursa 

 copulatrix 



Uncus of male 



Scales from f.-w.

 suffused with black not so. 

 rounded triangular.

subangulate. 



Now, in dealing with these points I should explain that 

 in discussing the forms in my monograph, the supposed 

 examples of silia which I had before me were specimens of 

 what M. Oberthur now calls siliana, and furthermore 

 amongst those labelled masamba were four examples of the 

 siliana form, but of the dark ground-colour similar to that 

 in masamba, a variety named by M. Oberthur A. siliana 

 antakara. It was on these examples that, in speaking of 

 the indentation of the hind- wing border, I based my remark 

 that " the same feature is observable in varying degrees of 

 development in a series of masamba, ." * Having removed 

 these examples, I must admit that the indentation of the 

 border is peculiar to the siliana form. Moreover, the black 

 suffusion of the inner margin of the fore-wing in masamba, 

 especially in the male, seems a good character. As to the 

 papilla related to the orifice of the bursa copulatrix in the 

 respective females, I regret I have not been able to make 

 out this character, alluded to by Professor Houlbert, 



* This remark of mine is curiously misquoted on p. 170, the word 

 " observable " being printed " mobservable " and emphasised by 

 small capitals.
