(f) The number of days which elapsed in the life of the 
fertilized female from hatching until the first eggs 
were deposited. 
Notes derived from one observation. 
A 15 hatched June 12th, first eggs deposited on June 
15th; a lapse of 3 days. 
(g) The number of days which elapsed in the life of the 
unfertilized female from hatching until the first eggs 
were deposited. 
Notes were derived from observations in two instances.

(h) Comparison of the number of days which elapsed in 
the life of the fertilized and unfertilized female from 
hatching to first egg laying. 
In the one case ‘of the fertilized female the length of 
time was 3 days. In the two unfertilized females the aver- 
age length of time was 31/2 days. 
The object of these notes was to ascertain whether or 
not the eggs are deposited when the female reaches a defi- 
nite age regardless of being or not being fertilized, but 
the data are too insufficient for any definite conclusions. 
(4) The number of days which intervened between the 
ending of copulation and the time when the first eggs 
were deposited. 
Notes derived from observations in five instances.

Al Same day 
A 3 Same day 
A 4 One day later 
ya One day later 
A 15 One day later 
The foregoing figures show that in three cases the first 
egos were deposited one day after the pairs were severed, 
in two cases the eggs were deposited on the same day. 
J. J. Davis! shows that in twenty Cecropia moths that 
were mated, sixteen began ovipositing on the evening of 
the second day, and four on the evening of the third day
