(/) The number of days which elapsed in the life of the 

 fertilised 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 

 iv ere deposited. 

 Notes were derived from observations in two instances.

(h) Comparison of the number of days which elapsed in 

 the life of the fertilised 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 3 1/2 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. 



(i) 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. 



KWOWN AS FIRST EGGS DEPOSITED 

 A 1 Same day 



A 3 Same day 



A 4 One day later 



A 5 One day later 



A 15 One day later 



The foregoing figures show that in three cases the first 

 eggs were deposited one day after the pairs were severed, 

 in two cases the eggs were deposited on the same day. 



J. J. Davis 1 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
