588 Mr. F. P. Dodd on some Remarkable 
pupate upon a twig or grass stalk, it is seldom that the 
pupal shell is met with; this protrudes and is removed by 
the ants and carried into their dwellings. 
The pupa forces its way through the “lips” of the 
cocoon, which close upon its terminal segments and hold 
them securely whilst the moth bursts the shell. All 
cocoons shown with the protruding pupal shells are from 
my boxes or were taken in the bush soon after construction. 
The moths emerge about 4 p.m. on the nineteenth or 
twentieth day after spinning. Expanse of the f is about 
23 mm., and of the § 28 mm. 
Though I have referred to this caterpillar as a friend 
of the red ant, I occasionally met with it in the company 
of a large blackish insect whose nests are usually at the 
foot of trees. This is a widely different species and the 
pupae are enclosed in cocoons, those of the red kind are 
naked. Once I found small, black ants amongst some 
homoptera and caterpillars, but they had probably driven 
off the red insects, for a habitation of theirs was not far away. 
Cgclotorna experta, Meyr. I never actually bred this 
species from larvae in my possession, nor have I had the 
larvae in two stages, but have taken pupae from above 
the nests where I had dug out young examples. As the 
ants’ paths led to trees upon which there were often groups 
of Jassidae during the year, similar to the species upon 
which the other caterpillars were to be found, I have no 
doubt whatever that it has two larval stages. It is a 
smaller insect than the preceding, and the larvae have all 
the same habits; they are coloured almost exactly the 
same dorsally, but those I had at different times were too 
small to show whether eventually they became blue on 
the underside. It was found but rarely in only one locality, 
and never in company with the other caterpillars. 
Cyclotorna egena, Meyr. At first I found the cocoons 
upon trees near the red ants’ nests, and bred out the 
moths, but failed to discover the caterpillars for a con- 
siderable time; finally I noticed a tree with great numbers 
of small Psyllidae thereon, and the ants in attendance, so 
I searched and found several of the extraordinarily flat 
and almost circular larvae now exhibited; they were 
moving about amongst the other insects, to which they 
paid little attention, but would stop now and then and 
apparently eat at tiny sugary-looking masses upon the 
branches, which with the aid of a lens I took to be dis- 
charges of the Psyllidae hardened. As there were also
