on the Bionomics of Southern Nigerian Insects, 369 
larva and is slightly réminiscent of this one, but it is much 
less ‘‘ knobby.” Altogether to-night I think I have three 
different Loranthus forms and the pink one [£. zasis]| is not 
included. All are wonderfully cryptic in their own way. 
What an astonishing piece of good fortune that a Loranthus 
should have grown on a Funtumia branch about ten feet 
from the ground. I just mount a step-ladder and pick them 
off in comfort. Curiously enough there are few ants on the 
trees and one of the forms has glands and tubercles (not the 
one, the camouflage expert). None were actually attended. 
Dec. 27, 1917.—An odd thing struck me this evening. I 
have got, I think, four different larvae on the Funtumia- 
Loranthus. The tree with its parasite is not 30 yards 
from the Cremastogaster-Hewitsona-Argiolaus maesa-tree, 
and yet I have never found A. maesa on the Funtumia, nor 
the other very large (the largest of all) Argiolaus alcibiades 
that is also found on the ant-tree. Yet I am sure they 
both feed on the same species of Loranthus that is also para- 
sitic on the ant-tree. But it is not a Funtumia, though I 
think it is also Apocynaceous. [It was the Apocynaceous 
Alstonia congensis Engler.| It is much taller, three times 
as tall, and it may be that the species that oviposit there 
fly high. Yet it is odd that maesa and alcibiades are 
not found on the Funtumia-Loranthus, and it suddenly 
came into my mind this evening that the Loranthus- 
“aura,” as it were, may vary according to its host, so that 
the chemotropic stimulus that impels a butterfly to oviposit 
in the one case is absent in the other. Of course it may be 
due to the absence of the Cremastogasters. The Funtumia- 
Loranthus is sparsely ant-tenanted, but a few Pherdole sp. 
being present, it would appear that the Lycaenid species 
do select particular ants. I have never found the Funtumia 
series pupae anywhere near the other tree. The maesa 
larva when it descends for pupation is always accompanied 
by ants, which it has difficulty in getting rid of in order 
to pupate in safety. 
Dec. 29, 1917.—Two of the new Lycaenids [E. farquhar- 
soni| have “ gone up.’ The pupa is as cryptically coloured 
as the larva. The two pupae are somewhat oddly placed 
on the twigs of Loranthus in lying across the twig instead of 
what is more frequent, along the twig. I am sure this is 
not accidental. You will see why when I send you material. 
The pupa in this position resembles a flowering cushion. 
Undoubtedly the imago, whatever it is, must be first cousin
