A. TERATONEURA ISABELLAE DUDGEON. 
[Farquharson’s first Teraloneura was a female taken at 
Moor Plantation, Dec. 12, 1913, in the act of drinking the 
secretion of ant-attended Coccids on a twig near the 
Apocynaceous Cremastogaster ant-tree Alstonia congensis, 
on which larvae and pupae of the Lycaenid were after- 
wards found. The following letter was written to his 
friend W. A. Lamborn, the others to me. | 
Moor Plantation. 
Dec. 24, 1913.—In response to your request I am now 
sending you a few notes on the Lycaenid which I brought 
in on the 12th of this month. 
About six o’clock in the evening I happened to pass the 
tree on which you had some time previously shown me 
some ant-attended Coccids. I was rather surprised to see 
a butterfly evidently in the act of sharing with the ants 
in the fluid provided by the Coccids. At the time, the 
Lycaenid was hanging from the underside of the twig with 
the wings outspread. Being unprovided with a net, I had 
to adopt the only other method possible, to catch it. 
Fortunately, owing to its intentness in supplying the wants 
of Nature, or to its natural ‘ protectedness ’—for even in 
the falling light it was by no means inconspicuous, I 
secured it easily with my fingers, and was pleased indeed 
that you regarded it as quite a prize. 
Feb. 18, 1914.—I received the letter with the great news 
of Teratoneura, last mail, which pleased me very much 
indeed, but I hasten to explain that its ever having 
reached the Hope Department is due in the first instance 
to Dr. Lamborn. From the note which I made at the 
time of finding it, you will readily perceive that it interested 
me primarily from its being found in the act of sucking 
up a Coccid secretion. This was a new thing to me, 
though, of course, not to my friend. He told me so, but 
went on to congratulate me with considerable solemnity, 
so that I felt rather awed and inwardly congratulated 
myself that the creature had been so intent on its meal 
that I, without a net, and absolutely innocent of its 
possible identity, yet managed to catch it by the precarious 
method of the finger and thumb. 
I wonder if any of us will ever penetrate the secret of 
the larval Teratoneura.
