5. On a Collection of Butterflies made by Mr. Richard 

 Crawshay in British East Africa. By Arthur G.

(Plate LXX.) 



During the past summer I received from Mr. Crawshay a box 

 of Lepidoptera and a letter dated February 8th, 1899, addressed 

 from Neugia, as follows : — 



" A few lines to let you know that I have lately returned from 

 a jouruey into Marauga, the S. and S.W. slopes of Mt. Kenya; 

 and that I was able to take some Butterflies, which, I think, will 

 please you. 



" Prom this — I mean the mention of mighty Kenya and its 

 18,600 feet — you must not infer that these insects have been 

 collected at any great altitude. Marauga is not so high as other 

 parts of Kikuyu to the westward, — for instance the neighbourhood 

 of Port Smith, which is 6400 feet. As a matter of fact it does 

 not average, I suppose, more than 5600 feet ; rising to the N. and 

 N.E. gradually into the mighty belt of forest surrounding the 

 mountain for many thousands of feet, and falling away to the 

 W. and S.W. of the Tana Eiver, which, where we crossed it, is 

 3850-3900 feet. 



" In all the thousands of miles I have travelled in Africa, I have 

 never seen a more lovely and more possible country than Maranga ; 

 nor more splendid specimens of its peoples than are the Wakikuyu — 

 though they are at present suspicious of and hostile to everyone 

 from the outer world. The Wakamba are the most veritable 

 worms in comparison with them. 



" However, you want to know something more of the surprises 

 which I hope are in store for you in the shape of the Butterflies. 



"The most promising of these are Skippers and Blues — one a 

 very large and powerful Blue with almost black wings on the 

 inside, which show a Purple-Em perordike glow, though with a
