METAMORPHOSES OF BRAZILIAN LEPIDOPTERA. 19 



only took one specimen of the larva, and having worked it 

 through to the perfect insect, am unable to place it in the 

 collection. This specimen I took near San Paulo, on 2l8t 

 December, 1877. It was five inches in length, and about 

 three-quarters of an inch thick. There was no horn on the 

 last segment, only a slight hump. The colour is green, 

 thickly peppered over with very minute black dots.
