native here, but is used as a shade tree. I got a butterfly 
on it just emerged, which may be an Iridopsis. 
[The butterfly referred to below is a female I. incredibilis, 
with the pupa-case in its silk-covered depression in the 
bark. They bear the date of emergence, Jan. 14, and the 
notes “ Larva hairy and predominantly red” and “ pupa 
in shallow depression in bark—silk-covered.” There is 
little doubt that the tree was Alstonca. | 
Jan. 12, 1918.—I have a Liptenine pupa just now which 
I found as a pupating larva not long ago—the pupa not 
unlike a Teratoneura, but the larva was different and 
“went up” in a depression on the bark of the tree after 
weaving a silk defence like an Jridopsis. The silk was 
finished before I met the larva and I couldn’t disturb it, 
but the predominant colour was red, and I do not think 
Ihave seen it before. [Jan. 26—‘ Itisa fine big Iridopsis.” 
—C.0.F.] 
Feb. 8, 1918.—I send the Iridopsis and its pupa-case— 
it is the one I told you of that had the larva with a lot 
of red. Iridopsis has one curious character: it generally 
pupates in a niche in the bark of the tree, but first spins 
a web of silk so as to shut itself in as some spiders do. 
Aug. 25, 1918.—[{ After referring to various Diptera and 
to larvae of Endomychid beetles, etc., haunting the “ ant- 
tree” (Alstonia) at Moor Plantation the letter continues. | 
There were also one or two young Hewitsonia larvae, and 
. I saw an Jridopsis come and oviposit. This must sound 
rather a tall yarn, all these things on one day, but such 
are the facts.

CITRINOPHILA TENERA KIRBY. 
[The single specimen sent by Farquharson is a male. 
It is accompanied by its pupa-case still attached to the 
bark of the Para Rubber tree, Hevea brasiliensis Miill. 
Arg. (Euphorbiaceae). It bears the note “ Lycaenid found 
newly emerged on Para tree, Agege. Pupa-case found

Agege. 
Oct. 18, 1917.—This forenoon as I was examining tapped 
surfaces of Para trees in connection with a really difficult 
disease problem that I think I may manage to solve, 
without the aid of a fungus (or, of course, an insect),
