Relationship between certain West African Insects. 493 
No. 484 Aand B. The pupa of A was found Oct. 7, 1911, 
in an ants’ nest in a head of Costus afer in Oni Clearing. 
The moth emerged Oct. 10. The larva of B was found, 
Sept. 27, 1911, in a similar situation in the forest 14 E. 
The moth appeared Oct. 10. 
4. Tinthia lambornella, Durrant, sp. n. (p. 513) (Hgeriidae). 
No. 674. The following note refers to the single bred 
specimen. 
“Feb. 26, 1912. The larva of this Aegeriid moth was 
maggot-like, and lived inside a stem which I cut open in my 
search for Lycaenidae. ‘These particular stems are often 
hollowed out by a large ant (Sima aethiops, Smith 2) which 
lives inside in company with some scale insects, samples of 
which are sent in spirit. The ants often form communities 
of 6 or 7 [probably workers with a 9] in an internode and 
have larvae with them.” 
The moth larva was found by itself in an internode, but 
ants were found in those on either side of it. The moth is 
accompanied by its pupa-case in a hollow stem, together 
with 9 2 Sima, bearing the date Feb. 29, and 2 stems similar 
to those which they inhabit. A note states that the ants 
were found each in a separate internode, at Alo, 4 miles E. 
of Oni. [The date of the above note (Feb. 26) shows 
that the moth larva was not taken with these particular 
ants. | 
5. Tortrix callopista, Durrant, sp. n. (p. 513). 
No. 625. The larva of this moth was found in the forest 
13 miles E., on Jan. 14. My note concerning it is as 
follows :— 
“Jan. 15, 1912. On going yesterday to obtain more 
Coccids as food for Lycaenid larvae, I discovered, on the 
stem of the same plant, some inanimate objects which 
looked very like Lycaenid larvae. In the walls of each were 
imbedded a number of Stictococci. On attempting to 
remove one with scissors I found that it was hollow and 
contained a maggot-like Lepidopterous larva, and that the 
wall covering the larva was composed of silk with brown 
material containing the Coccids on its outer side.” 
“ Jan. 29, 1912. This tiny moth was bred, Jan. 27, from 
a larva, similar to one sent in spirit, which I found in a 
tunnel constructed under Stictococci which are eaten by the
