 two weeks afterwards I was somewhat surprised to find four larvae 

 feeding on the leaves, and from a rather peculiar shade of color I at

During the summer of 1883 I had over 50 Cecropia larvte feeding 

 on a plum tree in my garden. At a short distance grew a peach, the 

 upper branches of which nearly touched those of the plum. On. the
