222 Bionomic notes on Butterflies from the Victoria Nyanza 
Seasonal Forms. 
Pressure of time, owing to my sudden departure to N.E. 
Rhodesia in January 1904, prevented me from studying 
the seasonal forms in this collection as much as I should 
have wished. They seem to be mainly of interest in the 
following particular. Just as on the equator the seasons 
are not nearly so well marked as in South Africa, so the 
seasonal forms are not so well marked, while intermediates 
are more common. 
The most interesting specimens are several fine dry 
season Precis calestina, Dewitz, and some remarkable 
intermediate and dry specimens of P. archesia, Godt. 
In conclusion, I should like to express my unbounded 
gratitude to Professor Poulton, D.Sc, F.R.S., of the Hope 
Department, Oxford University Museum, at whose sugges- 
tion the work was undertaken, and who has given me the 
inestimable benefit of his unique knowledge of these 
subjects.
