The object of the third memoir on this subject is to describe 

 a few more of the remaining forms of this collection in my 

 possession, and to figure some of the forms described in my 

 second memoir, published in 1916, of which I was unable to give 

 figures from want of space on the plate. 



The forms dealt with in the present memoir were taken at 

 Kedai (altitude 2500 feet) and Masongaleni (altitude 3000 feet) 

 in B. E. Africa, with the exception of a few specimens taken by 

 Lady Colvile at Meru, B. E. Africa. At the end I have described 

 two new forms from India and Australia, whicli have been some 

 time in my possession awaiting an opportunity of publication. 



It will be noticed that among the forms from B. E. Africa 

 there are a good many which are typical of the desert, of which 

 Euphiusa hermione, Ctenusa psamatha, Galactomoia berenics, 

 described in my former memoir, and Cynisca thisbe, in this one, 

 are notable examples, which seem to occur along with darker, 

 richer-coloured forms such as we should expect to meet with 

 in a country of considerable rainfall. Not being acquainted 

 with the district myself, and having no notes on the subject 

 by Mr. Feather, I regret T cannot offer an explanation of this 

 curious phenomenon. 



I notice that my first memoir on this subject, published in 



* Communicated by the Secretaiiy.
