634 OK BUTTERFLIES FROM WEST OF LAKE NTASA. [June 18, 



Felder's type ; but the same submarginal dots in pairs occur on 

 the primaries : on the under surface there is one marked difference, 

 the primaries show a discal series of divided spots, the first four, 

 from inner margin to lower radial, white, the fifth whitish, but 

 indistinct, the remainder forming a blurred greyish band to costa ; 

 in the silvery white band of the secondaries and all other respects 

 the specimen agrees with Felder's description ; and knowing how 

 much the allied P. nireus varies, I think it would be rash at present 

 to regard this as a distinct species. 



(S , Kasungu Mountain, Nyika, West of Lake Nyasa, Sept. 2nd, 

 1893. " Blue Swallow-tail " (E. C). 



Mr. Crawshay says : — " This is, I suppose, a Swallow-tail of 

 sorts, or what an expert would call a Papilio ? It is not a diflScult 

 insect to take, as it flops along lazily, and before perching hesitates 

 a good deal. I found it only on the top of Kasungu, and saw three 

 in all, of which I secured two." 



Later on, we may perhaps receive other examples of this form, 

 when it will be possible to decide whether the dfEerences between 

 it and typical P. pseudonireiis are constant. 



16. Papilio horribilis.

c? , Northern Henga, west of Lake Nyasa, Jan. 25th, 1894. 

 " Chocolate Swallow-tail " (B. C). 



Of this species Mr. Crawshay writes : — "Taken in Henga, at 

 about 3300 feet. I saw only one. It kept flying up and down a 

 small stream with high banks, and gave me a lot of trouble to 

 catch. My caravan was delayed on its account for the better part 

 of half an hour."
