the completed pupal condition. I found two empty 
pupa-cases of the Avgiolaus type and passed on to my 
Pterocarpus which was growing near by. Just under it 
I noticed another empty Lycaenid pupa-case, again of 
the Argiolaus type, which may indeed have come from the 
Hewitsonia-tree. 
May 18, 1917.—Did I mention that I believed that the 
Argiolaus were probably somehow connected with a 
parasitic Loranthus? I am now in a position to say that 
they feed on the Loranthus flowers. I will tell you all 
about it next mail.

Oct. 18, 1917.—Just before leaving Ibadan I noticed my 
Loranthus coming into flower. I think it flowers twice a 
year at least. I thought I'd look for some apparently fully 
fed larvae, for there’s one form I failed to breed. Both 
the pupae I got were unaccountably spoilt. I found inci- 
dentally a large proportion of the flowers galled by a Psylld, 
I think. Last time of flowering the flowers were normal. 
I got two Lycaenid pupae and several larvae [of A. panepe- 
yata|. That was on Friday the 12th inst. As bad luck 
would have it, I had no excuse left by which to avoid dining 
out and couldn’t get near them on Saturday evening. The 
day was a busy one and any work on them then impossible. 
On Sunday I was rather out of sorts (a suspicious circum- 
stance, but really unconnected with the unfortunate dinner) 
and in addition had to do some wretched packing up, as 
also on Monday. All this sounds most neglectful and I 
grieve to have to admit it, for last night I discovered what 
I had missed. The larvae had all pupated except one, 
which was manifestly dead. But in the bottom of the box 
(a glass-lidded tin of the ordinary kind) were several curious 
white threads, a ghastly, horrid Nematode I take them to 
be. There were I think five, two nearly as many inches 
long. If there is any class of animal on this earth that I 
loathe, hate and detest it is the Nematode. Snakes are, 
compared with them, a theme for poets. Perhaps after all 
it is a case of ignotum pro horrifico. Anyhow, they’re in a 
tube with spirit and you'll get them in due course. There 
was absolutely nothing else in the box from which such huge 
things could have come unless they lived in the Loranthus 
flowers. Looking at their semi-opaque bodies with a lens, 
they have almost an annulate appearance and I will not
