very long pink horn at the tail (Fig. 41). As the cater- 
pillars increase in size the horn becomes shorter, and after a 
time curves round. As the larva approaches maturity, it 
changes to a reddish-brown color, and after a third moult 
loses the caudal horn, which is replaced by a glassy, eye-like 
spot. The mature larva, when in motion, will measure 
nearly four inches in length, but when at rest it draws the 
head and two adjoining segments within the third, which 
shortens its body nearly an inch, giving it a very odd ap- 
pearance, with its anterior portion so blunt and thick. It 
is of a rich reddish-brown color, of a lighter shade along the 
back, with five nearly oval cream-colored spots along each 
side from the seventh to the eleventh segments inclusive. 
On the anterior segments there are a number of black dots; 
a dark, polished, raised, eye-like spot in place ofthe tail; the

in the cream-colored spots. It is a very voracious feeder,
