way—the host-tree, I mean—is Antraris toxicaria, var. 
africana.* I had just posted my letter on Tuesday when I 
found on my Puntunua-Loranthus still another extraordinary 
looking larva, very similar to the “‘ camouflage expert ”’ in 
shape, but in colour nearly black, a sort of dark ‘‘ mole ”’ 
colour except for one or two tiny white and brown spots 
posteriorly. I have searched for others without success 
and sadly believe that I must have missed them, for the 
one I had looked like a little bit of dead leaf that had 
accidentally stuck on a flower. I rather think it is the 
larva of the “decorated”? pupa Argiolaus [A. iulus] to 
which I referred in my last letter. [It was the larva of 
E. laon.| I have one of these pupae by me and will soon 
be able to clear up the point. 
Three of my “ camouflageurs”’ [larvae of E. farquhar- 
soni] came by an untimely end in a very curious way. 
A moth (? Pyralid) larva is present in considerable num- 
bers on the flowers. JI must have overlooked the presence 
of one or two of these in one of my tins in which the 
Argiolaus larvae were feeding. They in due course “‘ went 
up,’ and I didn’t trouble to put in more flowers. The 
wretched moth larvae attacked three pupae and devoured 
the contents, to my intense annoyance. If they had eaten 
the common species I wouldn’t have cared so much. 
Still, I’ve got four perfect imagines and there are some more 
to come, for I got three that had pupated on the lichen- 
covered bark of the Funtumia, so wonderfully cryptically 
coloured, just like little burrs on the tree-stem. I tried to 
photograph them, but my plates have got heat-fog and I 
cannot get good definition. 
I wonder if I mentioned that I have got another Loran- 
thus (same species) on a Funtumia close by the Cremasto- 
gaster-tree and infested with outposts from the main ant- 
nest. It is in flower like the Argiolaus one, but not a single 
specimen can I find on it. I must draw a plan of the 
ground showing distances. I introduced Cremastogasters 
in numbers into a tin containing about a dozen Argiolaus 
larvae, but they made no attempt to attend them. The 
Argiolaus-Loranthus off which I could have got dozens of 
larvae is but sparsely ant-infested, Pheidole sp. being the 
ant, and they are in attendance only on various Coccidae 
on the Loranthus. I can, I think, definitely say that these 
* Dr. Stapf informs me that the name foxicaria has never been 
published, and the species is A. africana Engl.
