1900] Hine — Odonata of Ohio 13 



ADDITIONS AND CORRECTIONS TO THE "ODONATA 



OF OHIO." 



James S. Hine. 



Since the j)ublication of the Odonata of Ohio, there have been 

 several species of dragonflies added to the State list, and we have 

 had reasons to change our minds regarding the identity of two 

 species at least. 



Enallagma Fischeri, Kellicott, is a synonym of Agrion antenna- 

 tum, Say, consequently the species will henceforth be known as 

 Enallagma antennatum. Say. 



Our Gomphus lividus, Selys, is Gomphus sordidus, Selys, and 

 . Gomphus externus, Selys, is Gomphus crassus, Hagen. 



The following species have been added : 



1. Lestes eurinus. Say, taken June 3, 1900, by E. B. Williamson 

 in Portage County. Numbers of both males and females of the 

 species were taken on Cedar Point, at Sandusky, July 10 of the 

 present year. 



2. Progomphus obscurus, Ramb., first taken at Ironton, June 1, 

 1899, by R. C. Osburn. The present year I took several specimens 

 at Vinton, June 10th. 



3. Gomphus abbreviatus, Hagen, (?) was taken at Loudonville, 

 June 10, 1899, by J. B. Parker and R. C. Osburn. The species was 

 common at the same locality June 14, of the present year. 



4. Neurocordulia obsoleta. Say, has been taken at Cincinnati 

 by Chas. Dury and his associates for three consecutive seasons. 



5. Neurocordulia yamaskanensis, Prov., was procured on Rattle- 

 snake Island in Lake Erie, June 28, 1900, by Prof. Osborn. 



6. Nasifeschna pentacantha, Rambur, was taken near Kent, 

 Ohio, June 21, 1900. In company with R. C. Osburn we procured 

 three pairs of this sj)ecies. Others were seen. 



DRAGONFLIES TAKEN IN A WEEK. 



Raymond C. Osburn and James S. Hine. 



During the week beginning June 17th, we collected insects and 

 fishes in the region of small lakes near Kent, Ohio. A list of the 

 Odonata taken during that week is interesting, as it shows the rich- 

 ness of the Odonat fauna of north-eastern Ohio and also the number 

 of species of this group that may fly in a certain locality at the same 

 time. 



1. Calopteryx maculata, Beauv. 



2. Colopteryx a?quabilis. Say. 



3. Hetairina americana, Fabr.
