328 THE ARRINDY SILKWORM MOTH. 



The LARVA of the Phalcena Cynthia, two-thirds the size of the animal 

 when it has arrived at its full size, and ready to spin. 



" The larvae 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, devouring 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.
