1916. In April 1916 a number of toon trees were sack-banded at 
the Zoologist’s request by the Range Officer, Changa Manga, and the 
cocoons obtained in the bands mailed to Dehra Dun in two consign¬ 
ments, RRD. 126 arriving on the 4th May, and RRD. 135 arriving on 
the 15th May. The emergence records of the moths from these 
cocoons is given in Table 36 below :—-

The above quoted data merely show that 2nd brood moths emerge 
in the Punjab throughout the month of May, as they do in Dehra Dun ; 
they do not show the limits of the brood-period or the dates of maximum 
abundance. 
Coventry noted the presence of larvae boring in shoots during August 
and September ; these represent the third brood larvae. 
Early in October 1912, shoots containing rohusta larvae were 
collected by the Divisional Forest Officer, Kangra, in Cheli Nerwana 
forest. These yielded moths in the fourth week of October represent¬ 
ing the existence of the fourth brood. A moth in the collection of the 
Agricultural Research Institute, Pusa, bred in November 1914 from a 
larvae collected at Taru, Peshawar, in the previous month is also of 
this brood. 
There is, therefore, at least a partial fifth generation in the Punjab.
