Larva, a. Full-fed. San Paulo, April 24, 1878. 



This handsome caterpillar feeds on a shrub growing in the 

 woods around San Paulo. The appearance is very little 

 altered in the different stages. Specimens in my possession 

 changed the skin 1st March, 14th and 28th March, and 8th 

 April, being full-fed April 24th. The caterpillars are social, 

 passing the day in a cluster on the upper surface of a leaf, 

 and separating at night to feed. 



Pupa, a, Full-fed, Ap. 20 ; Imago, June 17, '78 = 58 days. 



The cocoon is spun in any convenient spot, such as a 

 hollow in the trunk of a tree, etc., and is remarkable on 

 account of the skin of the caterpillar being thrust out through 

 the posterior end when pupation takes place. 



Imago, a, ? . h, ^ . 



Specimens full-fed at the end of April, produced the moth 

 at the beginning of July.
