Ou the moruing of June 5tli, 188"), I found eight Cecropia larvje, just 

 out of the egg, in one of my breeding boxes. I ininiediately placed 

 them ou a jfhuit of burdock which was growing in tlie garden. About 

 two weeks afterwards I was somewhat sui-[)i-ised to find four larvje 

 feeding on the leaves, and from a ratlier peculiar shade of color I ai, 

 first took tliem to be C. proinethca. From this time I watched them 

 closely ; when about half-grown, one left the plant and was lost, the 

 remaining three; reached a fair average size, and two wlien mature left 

 the plant to spin up elsewhere, and were lost. But I succeeded in 

 securing one cocoon. Vei-y possibly we may yet find that Cecropia 

 larvae will feed and mature ou the leaves of many hcrtjaceous plants. 



During the siimmer of 1883 I had over r)0 Cecropia larva* 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 ]ilum. On the
