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 vestwans, and numerous egg- 
masses were found each morning floating on its surface. ‘The 
great majority of the adults reared were 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.
