METAMORPHOSES OF BRAZILIAN LEPIDOPTERA. 29 



I took one specimen of this caterpillar full-fed and 

 walking on the ground, near San Paulo, on the 4th of 

 March, 1879. It was green, and had four curious curved 

 horns on the thorax. 



Pupa. Not preserved. 



The same day that I found the caterpillar it entered the 

 ground for pupation.

This remarkable caterpillar feeds on several kinds of 

 grass, and also some kinds of " taquara," or native bamboo. 

 It is covered with curious mossy hair, of a golden brown 

 colour. The ends of the hairs are many of them flattened 

 out like an oar.

When full-fed the caterpillar spins a cocoon of silk and 

 its own hairs, weaving the hairs into the fabric, and making 

 the cocoon look remarkably like the caterpillar itself.
