The eggs are laid in a cluster on the underside of the 



food plant, which is the same as that of No. IV., Eacles 



Laocoon. Eggs laid April 6th, 1878, were hatched April 21st. 



Larva, a, Full-fed. San Paulo, July 11, 1878. 



The caterpillar is social in its younger stage, but as it 

 grows, the individuals wander about and find new feeding 

 grounds for themselves. The appearance does not change 

 much through the casting of skin. Specimens taken in the 

 first stage in February, 1880, changed skin on the 9th, 

 14th, 20th, and 27th of that month, and were full-fed on 

 March 6th. 



Pupa, a. 



When full-fed the caterpillar spins a light web between the 

 stalks of the plant, or in any other convenient place, and in 

 this undergoes pupation, which does not take place for 

 several days after the web is spun.
