•• 
The broods were heavily parasitized, 51%, by a chalcid which 
accounts to some extent for the shortened swarming period. 
With this last record we are brought to the close of the annual cycle 
of the seasonal history of the species, as the broods emerging in August 
and September give rise to a second generation maturing in October 
and November. c/. Table II. 
Seasonal History in the United Provinces. 
In the United Provinces less evidence is available on the seasonal 
history, but there appears to be no very marked difference in the length 
of the life-cycle or in the succession and overlapping of generations. 
In November 1915, the Divisional Forest Officer, Gorakhpur Divi¬ 
sion, Eastern Circle, sent a Sal log cut from a coppice tree, which was 
left standing isolated by a clear-felling during the previous season and 
which died during the rains (R. R. D. 60). Diapus furtivus emerged 
in small numbers from this log at Dehra Dun in the 3rd week in 
January.
