the sea, which I do in a way, but not enough to reduce me 
to make them think I felt lke that. However, it is quite 
likely that the plant grows in East Africa and maybe 
phasma is there too, or whatever form I’ve got, and Lamborn 
will know the host-plant of Precis octavia. He will be 
able to clear it up if I never get another chance. 
Lagos. 
Aug. 31, 1918.—I sail to-morrow morning. Two days 
ago, or rather a day or two before that, I had decided that 
I had two sets of larvae on the Labiate, one green or reddish 
or both together, of which four pupated. Two of these 
have emerged, and they are a small and very pretty form. 
The other set are reddish only right through, but have grown 
very slowly. They are by far the most common. In 
fact, every plant one picks carries a few. None have 
pupated, and I begin to think they won't. Some have died 
of a fungus disease (in one only of my tins), but one of the 
other type also died. 
I sail to-morrow morning, but I am to see Dr. Connal this 
afternoon and he will be able to tell you the sequel. It is 
very bad luck that I should have to go just now, but it 
can't be helped. I feel sure that they are phasma. 1 
actually found a maculatus which had got caught by a 
spider on one of the host-plants, but it was dead. The 
worst of it is that the Camponotus is a “ night hawk,” and 
one seldom sees them at all in the day. 
Now I must close. I do hope I'll get the chance to com- 
plete the life-history myself on my return. 
Yours sincerely, 
C. O. FARQUHARSON. 
[These were the last words I received from my friend. 
There can be no doubt that the larger larvae were C. phasma 
and that they are carried by the ant to its nest to complete 
their development. The imagos of the smaller Lycaenid, 
which lives throughout larval life on the food-plant, were 
probably taken on the “ Burutu”’ and lost. I have tried 
but failed to receive any communication from Dr. Connal 
concerning the material left with him by Mr. Farquharson. 
It is probable that the smaller Lycaenid larvae possess the 
power of individual adjustment to the changing colours 
of their food-plant, in this respect resembling those of 
Lycaenesthes lunulata (p. 386).]
