on the Bionomics of Southern Nigerian Insects, 357 
on the way home also has a projecting pupa, but the 
third one’s [Hewitsonia similis] pupa lies along the surface 
of the substratum. But their larvae and that of EH. honorius 
are extremely similar in form, only differing in colour. I 
am trying to get a carefully differentiated series to clear 
up the whole thing. I have only seen about 3 species of 
Charaxes larvae. They are all of the same shape and not 
like any others I know. Argiolaus larvae are nearly as 
alike in some ways, but the Hewitsonia or Epitola larvae 
are as unmistakably related by form and habit as Charazes 
larvae. I thought for a time that the changes in colour 
were cryptic changes of one form. Teratoneura is a little 
different. Jridopsis is nearer, but the larva has the 
distinctive habit of spinning a silk protection before 
pupating. - You will notice too the likeness of the Citrino- 
phila pupa-case to the Hewitsonia and Iridopsis types. 
If only I had time and a forest district to work in I could 
do them all up. When the Director comes back I think 
I'll try to get a local holiday to a forest district. I know 
exactly where to look for these things, and I’ve only to 
get into a decent district to get lots more of other species. 
I think I'll have earned a holiday, for Pve been nearly 
17 months out now without anything but the statutory 
days—Xmas, Bank, Empire, New Year, and it isn’t 
much. At times I don’t feel any too willing to get up 
early in the morning, and I lose more sleep than I like to. 
Still one must make the best of things. This is an extra 
mail, sprung on us on two days’ notice, so I won’t have 
time to write more.

which I do hope will reach you all right, as I have a feeling 
that even two (if they arrive in good order) will be, at least 
in a small way, a Xmas contribution that will interest 
you. I know the larva, but have not yet got one in spirit.
