ADDITIONAL OBSERVATION.—One hundred and forty pre- 
pupe of Lucilia were collected on the 28th December, completed 
pupation between 29th December and 10th January, emerging 
between 4th and 18th January, the pupal period being as 
follows :— 
3 specimens in 5 days. 
27 specimens in 6 days. 
106 specimens in 7 days. 
4 specimens in 8 days. 
It will be noticed that during the early summer (October 
and early November) the great majority of pupe required 
eight days before emergence, while during the remainder of 
November about twice as many needed only seven days as 
required eight, and in the following months, December and 
January, the great majority needed seven days. The fact 
that some completed their pupal stage in the short period of 
five days is worthy of note.
