on the Bionomics of Southern Nigerian Insects. 355 
24 miles south of this) on which I got the curious little 
Diptera last tour [p. 444]. You may recall my description 
of their curious larvae, which wandered about freely 
among the ants. I did not find them, however, at Agege. 
I do not know the species of tree, but it is habitually 
inhabited by ants, and always carries large carton 
nests. 
[The following note in the same letter refers to Epitola 
concepcion Suft.] I have also sent you another little 
Lycaenid with a very Hewitsonia-like pupa-case. I bred 
it out from a larva (a hairy moth-like larva too) which 
I found about to pupate on Lamborn’s old Hewitsoma 
tree [ Alstonia]. 
March 18, 1917.—I must say the Epitola honorius 
pupa-case more closely resembled the Hewitsonia than 
either of them resembles the Teratoneura and yet the 
poise of both is not unlike, though the two former have a 
much broader attachment than the latter. In fact, I 
think that except for the colour of the pupa (and in Hewit- 
sonia at least it varies a little to harmonise with the back- 
ground) which is rather darker in Epitola, I should find 
it hard to tell one from the other. 
All the larvae have the little protrusible process on the 
outer side of the pro-legs (one spirit specimen of Terato- 
neura shows these exserted), but so also have the Ptero- 
carpus larvae [Lycaeninae, see pp. 383, 485, &c.]. 
Agege. 
Oct. 18, 1917.—I have also sent two Argiolaus and two 
Hewitsonia from a tree here in Agege on which I got the 
very tiny Lycaenid of which I told you last mail, which 
duly emerged. I am waiting for a large mail steamer 
to carry it home. The tree is a tall buttressed one of 
the Apocynaceae family, I think [it is the Moraceous 
‘Antiaris africana], but all round the base I found 
fallen Loranthus corollas of a different species from the 
one on which I got the Lycaenids at Ibadan. There is, 
of course, a Cremastogaster nest rather beyond my reach. 
I took in the Hewitsonia pupae for a special reason. E 
was to put you a query about them and found you had put 
it to me in slightly different form. Of that I will say 
more. I, as a matter of fact, was to suggest that the 
Hewitsonia larva was rather variable, and was to promise 
‘to look into the question closely.
