I found only one specimen of this caterpillar, feeding on 

 a species of Iris, near San Paulo, at the beginning of 

 December, 1877. When full-fed it was three inches and a 

 half in length. The body is of a deep black colour, and is 

 covered with long tufts of venomous spines, which are of a 

 rich chestnut colour near the body, and black at the tips. 

 When irritated, the caterpillar made a curious clicking 

 sound, apparently with the mandibles. (See Plate VII, 

 fig. 3).

The caterpillar began to spin on December 18th. The 

 cocoon is slight, and is spun between the leaves of the food- 

 plant. While in the pupa state the insect from time to time 

 gave a series of violent shakes and twistiugs within the 

 cocoon.
