 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).

 or arhar (Cajanus indicus) and is found commonly 

 in Bombay, Central Provinces and Behar. It has 

 not been reported from many districts, but is an 

 inconspicuous insect, and is probably common

 extensively, the pest does no appreciable harm. 

 Where small areas of tur are grown, it may be very
