111. PAPILIO DEMOLEITS. 



Papilio demoleus, Linnaeus, Mus. Lud. IJlr. p. 214 (1764). 



Taru, 18th & 20th December, 1896; Mombasa, 4th January; 

 Maungu Inkubwa, 21st March ; between Voi and Ndi, 1 9th May, 

 1897. 



112. PAPILIO CONSTANTINUS. 



Papilio constantinus, Ward, Ent. Month. Mag. viii. p. 34 (1871) ; 

 Afric. Lep. i. pi. i. figs. 1, 2 (1873). 



Two pairs, Maungu Inkubwa, 21st March, 1897.

Papilio nireus, Linnaeus, Mus. Lud. Ulr. p. 217 (1764).

 March, 1897. 



I must confess that I see no possible reason for separating this 

 variable species under two distinctive names. 



114. PAPILIO MEEOPE (var. DAEDANUS, Brown). 

 Papilio merope, Cramer, Pap. Exot. ii. pi. cli. A, B (1779).

Although I do not consider that the Eastern type should be 

 regarded as identical with the Western, it is more convenient 

 (until the forms of so-called P. merope have been thoroughly 

 studied) to retain this name for them all. The Southern form is 

 apparently identical with the Eastern one, but the true P. werope 

 of Cramer seems to me to be the West- African type with black- 

 and-white female. The corresponding Eastern form is that now 

 received, the female being also of the black-and-white type, but 

 the male differing in constantly having a broad continuous black 

 belt across the secondaries ; it thus comes nearest to the male of 

 P. cenea, which Mr. Trimen regards as a variety of the same species ; 

 perhaps he has proved this point, but it seems odd for the same 

 insect to mimic two totally dissimilar Danaince.

115. SAEANGESA ELIMINATA. 



Sarangesa eliminata, Holland, P.Z. S. 1896, p. 9, pi. v. fig. 2. 



Taru, 22nd November and 20th December, 1896; Voi, 22nd 

 April, 2nd May, and 22nd June, 1897. 



The specimen obtained on the 22nd April is a distinct mtergrade 

 to S. pertusa, and I believe, when the species of this group are 

 better understood, it will be found impossible to separate most of 

 the species of the S. motozi group ; they are simply ridiculously 

 close, whilst (so far as I can judge from our poor series) they 

 probably all occur together. We have S. pertusa, S. synestalmenus, 

 and S. motozioides occurring with S. motozi in Nyasaland ; S. per-
