9). Cocoon of the Leaf casemoth, Vhyridopteryx 
hubnem. This leaf casemoth caterpillar does not keep to 
one kind of food plant, but it is generally gum leaves or 
pine needles that it chooses to bedeck its bag with. The 
leaves are not wholly matted in, but are just lightly 
fixed to the bags by their upper edges. 
10. Cocoons of the brown Bat moth, Chelepteryx 
collesi. The cocoons of the Bat moth are among the 
largest of the caterpillars about Sydney. Neither cater- 
pillar nor cocoon-are easy to handle, because of their spines. 
When the red-brown, bristly caterpillar is fully grown 
it begins to spin its cocoon, not shooting out its spines till 
it is well enclosed in silk; but when it does so, the cocoon 
is as prickly as a cactus. One of these caterpillars spun 
a lot of loose silk into a delicate mesh, and then aban- 
doned it. One of these eccoons contains a live pupa now. 
11. A similar spiny cocoon cf a moth whose name f 
have not yet discovered, 
12. Cocoon of the Painted Moss moth. This is a 
dark little heavy felt bag, with a long neck. 
13. Cocoons of Hepialus exima. ‘This caterpillar feeds 
on the stems of watergums, and forms a felted loose bag 
all round the branch, and is said to remain in the larval 
state for nearly a year. ‘The bag shelters the pupa, which 
is in a cavity in the interior of the twig. It eats the web 
off in front of the cavity just before it pupates, and puts 
a wad of felt in its place. The horny pupal head of the 
moth will push this wad out when it is ready to emerge.
