Relationship between certain West African Insects. 487 
males 555 and 662. In order to confirm the sex, Mr. 
Eltringham kindly mounted and examined a fore-foot of 
the specimen which emerged Feb. 16. E. B. P.] 
No. 662. This male specimen was bred from a larva 
found in the forest 14 miles E. on Feb. 4, 1912, which 
pupated Feb. 6, and emerged Feb. 16. The ants running 
in and out of the cavity were C. buchneri r. winkleri, of 
which 11 were sent.* The following note, dated Feb. 26, 
refers to the specimen :— 
“This Lycaenid was walled up in the stem when in the 
pupal state by débris brought by house-ants, P. rotundata, 
var. These butterflies when freshly emerged seem to me 
to possess an excessive amount of downy material about 
the coxae and ventral surface of the body which frequently 
gets rubbed off and deposited on the edges of the opening 
by which they leave the stem.” 
[F. P. Dodd, in “ Entomologist,”’ 1902, p. 184, speaks of 
the thick covering of loose scales by which the freshly 
emerged Liphyra brassolis, Westw., is protected from the 
attacks of Oecophylla ants. | 
The hollow stem which contained the pupa still retains 
plenty of the débris brought by the house-ants. 
No. 663. A female specimen was bred from a larva found 
in the forest 14 miles E., Feb. 2, 1912, on a similar stem. 
It was attended by a race of C. buchneri. 
Pupation, Feb. 7; emergence, Feb. 16. This specimen 
is dwarfed, dark, and yellow-marked beneath like females 
660 (p. 486). 
No. 670. Two female butterflies were bred from larvae 
found on a similar stem in the same locality, Feb. 14, 1912. 
They entered the central cavity on Feb. 15, and conse- 
quently I lost sight of them. Ants were as usual in 
attendance, but though none were sent home they were 
without doubt a race of C. buchneri. 
One butterfly emerged Feb. 22, the other was flying 
8 a.m.; the date unrecorded, but probably Feb. 22. 
The association of the particular ants C. buchneri with 
the larvae in nature is perhaps to be explained by the 
fact that these ants favour the particular tree, which 
provides food for the larvae, as a site for their carton 
nests. 
* Four ants only were determined by Prof. Forel, but Mr. Crawley 
and Mr. Hamm have no doubt that the whole series belongs to the 
race winkleri.
