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

 fanning 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 iny 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. tarquinia being the male of P. ecopansa. 



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

 female of P. tarquinia ; 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.

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

 case in localities where it is found." 8 • " The males of this 

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

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

 of this butterfly." (P. G.)

" This is an insect which 1 think I took on my journey to the 

 8.W. slopes of Mt. Kenya in 1898-18U9. 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." (P. C.)
