concealment, perhaps in the daytime. There are lots 
of points to clear up, but every time I go to Agege I'll 
get a little more study put in. 
March 2, 1918.—My Embiids haven't got their wings 
fully developed yet, so they are not sent. I hope they 
will get home all right. 
March 23, 1918.—I have nothing to send this mail, for 
I have been very busy, but I’ve got a winged Embid, 
the wings blue-black and slightly lustrous as I remembered 
seeing once a long time ago. 
July 19, 1918—I have found a most populous and 
prosperous species that lives in bags of cotton-seed, the 
tunnels and greater part of the web bemg on the outside. 
It will be as easy as possible to send you really great 
specimens. <A British Cotton Growing Association’s store 
near by, which is full of bags of cotton-seed, simply swarms 
with the insects. I haven’t yet found out what they eat. 
I am to try to bring you home a live family. If I can 
get safely to a British port I will immediately post them 
to you, and perhaps if they were put in an incubator at 
about 80° they might live long enough for some one to 
study them fully. It is a different species from the Para 
one, but the silk tunnels are exactly the same. I haven't 
seen any winged forms. 
Aug. 12, 1918.—The other box contains a piece of 
sacking with -typical Embud silk galleries. There is also 
a small tube, with four of the Embiids. The species is 
much smaller than the Para Rubber one. I hope to bring 
home some of them alive. So far no winged forms have 
appeared. I am not yet certain as to the nature of their 
food. Their galleries permeate the cotton-seed. I hope 
the specimen will not get rubbed more than can be helped. 
The specimen will give you an idea of what a Para tree 
looks like when its bole for ten or fifteen feet up (and even 
well up the higher branches) is covered round and round 
with such a web. The Para one’s web is scarcely so dense, 
being as it were translucent, which gives the trees the 
‘‘ shostly ”’ appearance which I have already described. I 
do not think that I exaggerate when I say that there must 
be hundreds in a colony. In the cotton store hundreds of 
bags had splashes of white on them, and altogether there 
must have been thousands of the insects. The store had 
unfortunately to be emptied (the seed being distributed), 
but I’ve little doubt but that they will appear again next
