Various notes on the habits of the larva were com- 
municated for me by Prof. Poulton to this Society in 1911 
(Proceedings, pp. ci-civ). The ants which construct a nest 
over the head of the plant Costus afer, Ker.-Gawl. 
(Scitamineae), in the calyces of which the larva lives, have 
since been determined as belonging to the genus Pheidole, 
and two species are probably concerned, viz. P. auwriwilli 
kasmensis and P. rotundata, the former being more usually 
found. 
No. 442. The 15 butterflies of this series were all bred 
from larvae and pupae found in the calyces of Costus afer 
between Sept. 11 and Oct. 7, 1911. All were covered in by 
nests built up by Phezdole. The larvae and pupae were 
found in Oni Clearing and in the forest at various points 
up to 14 miles E., the majority coming from this latter 
distance. Specimens D, EH, F, G, J, O and P (all males) 
bear notes stating that they emerged at 9 a.m., and an 
eighth unlettered g specimen “about 9 a.m.” Only 2 
specimens, B, 9, and G were captured as larvae, on Sept. 10 
and 13 respectively: they pupated Sept. 11 and 15 and 
emerged Sept. 21 and 26. Of the remainder A, C, and K 
are g, I, L, and N 9. Nearly all the pupa-cases are con- 
tained in the calyces of the food-plant—never more than 
one in each. The remainder are attached to the scale-like 
leaves of the flower-head. 
No. 474. The female parent, referred to in Proceedings, 
1911, p. cil, was captured in a swamp in Oni Clearing, 
Sept. 18, 1911. She died and was partially eaten by ants 
Sept. 21. The 3 probable offspring, all J, emerged Oct. 2, 
6, and 7 respectively. The larvae and pupae were tended 
by house-ants, P. rotundata. The conditions of the breed- 
ing experiment, as described in the Proceedings, leave little 
doubt that these 3 butterflies are the offspring of 474 and 
therefore that the cycle from egg to imago is run through 
very rapidly. 
No. 580, A 9 and B g. Two pupae were found in Oni 
Clearing on Jan. 4, 1912, in the usual situation on Costus 
afer, and 50 P. aurivillii kasaiensis were collected from the 
ants’ nest. On Jan. 6 the pupae were covered in the house 
with material brought by Pheidole rotundata, 20 of which, 
19 $ min. and 1 § maj., were collected. 
Emergence of A, Jan. 6; of B, 9 a.m. Jan. 9. 
No. 582, 9. One pupa was found Jan. 3, 1912, in Oni 
Clearing in a calyx of Costus afer covered by a nest of
