BRAZILIAN LEPIDOPTERA. 45 



The pupa is attached by its " tiiil" and a loop round the 

 thorax to a twig of the tree, and from its position and colour 

 (green, with a few rusty markings,) it looks remarkably like 

 a little fruit. The time passed in the pupa state varies 

 considerably.

Specimens full-fed in October appeared as perfect insects 

 in February. Others, full-fed in January, produced butter- 

 flies in February. I have found full-fed caterpillars at the 

 end of February, 1881. It remains to be seen when these 

 will produce imagos.

When the caterpillar issues from the egg it is about five 

 millimetres in length, and is of a purplish red colour, with 

 bright yellow bands. The first thing it does after leaving 

 the egg is to make a house within which to retreat when not 

 engaged in feeding; this is done by cutting out a piece of leaf 

 seven or eight millimetres in diameter, and fixing it on to 

 the upper surface of the leaf in such a manner as to leave a 

 passage for ingress and egress. When it has grown suffi- 

 ciently to enable it to pull the leaves themselves together 

 and fasten them with silk, it makes its retreat in that way. 

 From its secluded habits it is difficult to see the changes of
