METAMORPHOSKS OF Br.AZILIAN LEPIDOPTERA. 21 



near San Paulo, in the middle of March, 1878. It is short 

 and stumpy, and is thickly covered with velvety hairs that 

 give it a beautiful glossy appearance.

On March 14th, the caterpillar began to spin, or rather 

 to build, its very beautiful cocoon, which it did in a very 

 remarkable manner. Choosing a spot on the wall of my 

 room, it began by plucking itself and laying the hairs round 

 it in an oval shape, attaching them to the wall with gum. 

 Then another layer was laid on the first, and so on, building 

 up the cocoon in the most workmanlike way. It was a 

 wonderful sight to watch the little creature lay the hairs 

 down so symmetrically, first on one side and then on the 

 other, building a house out of its cast-ofi" clothes. The 

 hairs are very beautiful under the microscope, being barbed 

 all the way up, the barbs being so long and fine as to give 

 the appearance of feathers.
