Notes on the Eggs of Epagoge sulphureana Clemens. 



BY R. L. WEBSTER, Ames, Iowa. 



In some cages in the insectary at Ames last year, some little 

 data was obtained on the number of eggs deposited by a 

 single female moth of Epagoge sulphureana Clemens The 

 larvae of this species were found at Charles City, Iowa, on 

 August 5, 1908, on apple nursery stock, and a supply of them 

 was sent to the insectary to rear. When the moths appeared, 

 two insectary cages, large glass jars covered with gauze, were 

 set up with a single male and female in each cage, in order to 

 determine the number of eggs deposited by one female moth. 

 The eggs were laid on the sides of the glass jar and the fol- 

 lowing data was secured: 



Experiment A, I male and i female.

Scattering eggs 5* 



Total eggs, 263 Range, 12-40 



Average, 25.6 



In the case of the clusters la, ib, 4a and 4b, the separate 

 figures indicate two depositions on different nights, and these 

 are regarded as distinct clusters. The scattering eggs, marked 

 with a *, are not included in computing the average number of 

 eggs to a cluster.
