486 Mr. W. A. Lamborn on the 
alarmed run about with abdomen uplifted and turned 
forwards over the thorax.” 
The note of Nov. 27 continues: “I found that the 
pith in the centre of the stem had largely been eaten away 
and that on the inner side were a number of little pits. In 
some of the older tunnels thus produced were white scale 
insects. Normal stems have no central cavity.” 
I feel confident that the larvae of Triclema eat only 
the young cortex of this particular plant, and that the 
presence of Coccids is accidental as far as they are con- 
cerned, although there probably is relationship between 
the Coccids and the ants. 
No. 657. Five male and 3 female butterflies. One of 
these latter is the specimen described by Mr. Bethune- 
Baker (p. 503). A note in my letter of Feb. 26, 1912, 
records that no less than 12 pupae were found in the forest 
4 mile K., on about Feb. 13, in the central cavity of a stem 
similar to that already mentioned. Three of the pupae 
were injured in opening it up and one other pupa died. 
Ants, undoubtedly one of the races of C. buchnert, were 
running in and out of holes in the stem as in the preceding 
case. The stem was suspended in a box in my bungalow, 
and, on Feb. 14, twenty-three ‘“‘ house-ants,” P. rotundata, 
var., were collected off the pupae. 
One male emerged about 7.30 a.m., Feb. 14, the remaining 
butterflies about 8 a.m., and probably on the same date. 
Four ants bear the note “ ants in cavity of stem with the 
12 pupae. Feb. 13, 1912.” [Owing to some error these 
examples were not sent to Prof. Forel, but Mr. W. C. 
Crawley and Mr. A. H. Hamm are confident that they are 
C. buchnert winklerc. | 
No. 660. Two female butterflies. Three pupae were 
found in the forest near Oni, in a similar hollowed stem 
about Feb. 13, but one died. The precise ants in attend- 
ance on them have been mislaid, but they were undoubtedly 
a race of C. buchnert. 
One butterfly emerged about 9 a.m. Feb. 15, the other 
about 8 a.m. Feb. 16. 
[Both specimens, as well as No. 663 (p. 487), are somewhat 
dwarfed, and their upper surface is of a uniform fuscous 
tint with barely a trace of the markings of the normal 
females as described by Mr. Bethune-Baker (p. 503). The 
under-surface markings are much yellower than in any of 
Mr. Lamborn’s 5 normal females, in this respect resembling
