The butterfly is common in the neighbourhood of San 

 Paulo. In its habits it closely resembles A. Ajnphinumey 

 settling on the trunks of trees with the head downwards and 

 the wings spread out against the bark. From its resting- 

 place it every now and then takes short flights after passing 

 friends, circling round and making a noise like a series of 

 electric sparks.

The caterpillar feeds on a species of bramble, and is of a

 the ends. When not eating, it rests with the thorax raised 

 and the head bent down, giving it a very grotesque appear- 

 ance. When full-fed the colour changes to a dull yellowish 



brown.
