" A graceful insect, both when on the wing and when at rest 

 tanning its wings. This ( $ ) and the succeeding number were 

 taken on the wing with a single stroke of the net when chasing 

 one another round and round over my head. It is an active 

 insect of rapid gliding flight. I have some recollection of having 

 taken this butterfly, or one very nearly resembling it, in the 

 Mweru country in 1891-1892. Dark yellow spherical ova."

The specimens now sent prove the correctness of Prof. Auri- 

 viilius's decision as to P. tarqidma being the male of P. expama. 



It has been suggested that P. heliogenes from Nyasa is the 

 female of P. tarquiaia ; but the pattern of the primaries seems to 

 me to differ too much for this to be correct, and I note that 

 Prof. Aurivillius regards the two as distinct. 



22. Hypoliitnas misippus. 



Papilio misippus, Linnaeus, Mus. Lud. Ulr. p. 264 (1764).

2 . " Common, though not in such numbers as is generally the 

 case in localities where it is found." tf. "The males of this 

 species are distinctly in the minority here. For ten females I 

 doubt if I see one male." (R. C.)

 " Three weeks or so ago I did not remark a single fresh specimen 

 of this butterfly." (R. C.)

" This is an insect which I think I took on my journey to the 

 S.W. slopes of Mt. Kenya in 1898-1899. It somewhat surprises 

 me therefore to find it here. By luck I came on this specimen 

 in the early morning when not very lively. Its favourite perch 

 seems to be a tree-trunk, where it sits generally head downwards. 

 It is an active insect, of short, rapid, skipper-like flight." {R. C.)
