outside. Having' eaten one seed it makes a hole opposite anotlier and attacks 

 that. The L^^rva is green or brown or a mixture of both. The colour is 

 similar to that of the pod, that singular mixture of green and brown, and 

 so is not easily seen. The body is dotted with dense tufts of spines and 

 hairs, the former of peculiar form, either single or 

 radiating from points in each segment (fig. 157). 



After a larval life of 25 to 30 days, the chry- 

 salis is found on the pod. It is coloured exactly like 

 the pod and is clothed in fine hairs as is the larva. 

 After seven days, the moth emerges, a singularly 

 graceful moth, with long narrow wings. It may be 

 found flying in the dusk and comes readily to 

 lights (fig. 160).
