Hine — Odonata of Ohio 
13 
ADDITIONS AND CORRECTIONS TO THE “ODONATA 
OF OHIO.” 
James S. Hine. 
Since the publication 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. Progomplnis 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 .1. 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. Nasiseschna pentacantha, Rarnbur, was taken near Kent, 
Ohio, June 21, 1900. In company with R. C. Osburn we procured 
three pairs of this species. 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 sequabilis, Say. 
3. Hetserina americana, Fabr.
