 This caterpillar feeds on a species of Ficus, a large tree 

 much grown about San Paulo for ornamentation. It is 

 full-fed in March and April. When full-fed the appearance 

 becomes very much altered by the formation of smoky-black 

 rings round the segments, and the duller shade of the green. 

 See fig. 12, 13, plate V.)
