Agege. 
Oct. 18, 1917.—On the same Agege Hewitsonia-Argiolaus 
tree [Antiaris africana] I found some curious little spiny 
Coleopterous larvae that the ants seemed to leave alone. 
These run about freely, and not really very rapidly, 
apparently being able to take their own time, regardless of 
the ants. They pupate on the bark, in tiny pits or crevices. 
In one case I got two just beside a Hewitsonca pupa. Till 
yesterday I only had two pupae. These I got before going 
to Ibadan at the beginning of this month and they bred out 
there. I sent one as they were scarce, but now I shall have 
half a dozen at least, I think. I have decided that they 
are Endomychidae. One emerged yesterday evening about 
8.30, and this morning there were two in addition. When 
newly emerged (the first one) it was whitish in colour and 
the wings were for some time kept unfolded and projecting 
beyond the elytra.* It seemed to me to be an amazingly 
large animal to have come out of such a tiny pupa-case. 
The Endomychid larva (if I have correctly classified it) 
appeared to feed just as the Hewitsonias.

April 17, 1918.—I am so glad that the Endomychid was 
workable after all. [Mr. Arrow considered that the colour 
of the first specimen shown him had not quite matured. ] 
They must take a good time to harden, for I left them, in - 
one or two cases, at least 24 hours before killing. However, 
[ll probably get better material this year again. . 
Aug. 11, 1918.—By the way, I found the Endomychid 
larvae on the Cecidomyia tree [p. 442] to-day and have got 
one pupa. I am sure it is the same one as I get at Agege.

Aug. 25, 1918.—While I was stooping down & a tin I 
noticed one other thing. At the bottom of the tree is the 
* The following note was written Oct. 18, 1917, at Agege: “ Just 
lately I have been breeding out a Coccinellid that feeds on Aspidi- 
otus destructor, the pest lam going to Okigwi to investigate. They 
do not appear to expose the wings after pupation [like the above 
Endomychid] but sit as still as a Coccid and looking like one.”
