Life History. 
The writer found the caterpillar of this moth tunnelling in 
Cassia Fistula, Linn., pods at the beginning of February. The 
grub was at the time nearly full-grown. It changes into the 
pupal state towards the end of the month by which time the 
pods are ripe. The moth appears at the beginning of May,1 
C. Fistula flowers in April, and it is probable that the moths 
lay their eggs near or on the young forming fruit, and the 
larve on hatching out tunnel into the pod and increase in size 
with the growth of the bean. More than one egg is laid in this 
position by the moth since several larve have been found in 

1 The pod taken by myself on the 1st February and brought into Dehra 
was made over to Babu Birbal, Curator of the Imperial Forest School, in 
April, and he bred out moths from it on the 3rd May.
