Standards of the Number of Eggs Laid by Insects — III.* 



Being averages obtained by actual count of the combined eggs from 

 twenty (20) depositions or masses. 



By Arsene Girault. 



Although this insect has been studied thoroughly, the esti- 

 mates of the number of eggs deposited by it vary from one to 

 eight hundred. On the whole, however, the estimates ap- 

 proch the average here obtained. 



The egg- masses, from which these counts were made, were 

 taken from various trees in Maryland, Virginia and the Dis- 

 trict of Columbia. 



Prof. Jas. S. Hine, of the Ohio State University, who has spent the 

 winter collecting in Guatemala, has returned with an excellent collection 

 in various groups of animals but especially of insects, it being particu- 

 larly rich in Diptera and Hemiptera.
