Standards of the Number of Eggs Laid by Insects VL* 



Being averages obtained by actual count of the combined 

 eggs from twenty (20) depositions or masses. 



BY A. ARSENE GIRAULT. 



7. CULEX RESTUANS THEOBALD. 



The egg-masses were obtained at New Richmond, Ohio, 

 during July, 1907, by exposing a large tub of water out of 

 doors. Within a week afterwards, the water in the tub was 

 literally alive with the young of restuans, and numerous egg- 

 masses were found each morning floating on its surface. The 

 great majority of the adults reared w r ere captured and care- 

 fully examined, but during the month no other species made 

 its appearance. 



I am indebted to Mr. Frederick Knab, U. S. National 

 Museum, for determination of the species.
