128 THE ARRINDY SILKWORM MOTH. 
The Larva of the Phalena Cynthia, two-thirds the size of the animal 
when it has arrived at its full size, and ready to spin. 
« The larvee arrive at their full size, which is 
from two and a half to three inches, in the space of 
about one month ; during which time they, like the 
caterpillars of the common silkworm, cast their 
skin three or four times. They are also composed 
of ten segments ; across the middle of each are 
several small, soft, conic-pointed tubercles ; other- 
wise they are smooth and delicately soft. The 
prevailing colour pale or sea green. In this state 
they are very voracious, deyouring daily many times 
their own weight of food. Like the caterpillars of 
P. paphia, they are furnished with eight pairs of 
legs, viz. three pairs of pectoral, four pairs abdomi- 
nal, and one pair of caudal.
