ARTICLE VI.— CATALOGUE OF THE ODONATA OF 



OHIO. 



Part III. 



By D. S. Kexucott, Columbus, O. 



The former parts of the catalogue* contained the names of 

 eighty-six species. During the season of 1896 several addi- 

 tions have been made to our known species, and this Part III 

 is published to extend the list and to correct certain errors of 

 identification in the preceding parts. The species, No. 86, 

 which was referred, with doubt, to Diplax madida Hagen, 

 proves not to be that insect and the name should be erased. 

 Concerning the proposed variety, Gomphus fraternus variety 

 ivalshii, it may be said that a more complete series of 

 fraternus has been obtained, and it does not longer seem best 

 to continue the varietal name. It is, therefore, withdrawn 

 and G. lividns, taken in 1895, DU t. not hitherto identified, 

 given its place, as follows : 



77. Gomphus lividus Selys. 



One male taken at Sugar Grove, May 18, 1895. The one 

 captured was resting with others in a roadway at a long dis- 

 tance from permanent water. 



The additions of 1896 are nine in number and are as 

 follows : 



(2) Agrionin^. 

 86. Enallagma aspersum Hagen. 



Examples of this pretty and abundant species were first 

 taken by my associate, Jas. S. Hine, at Minerva Park, near 

 Westerville, May 4th. It was abundant at Sandusky, July 

 30th, and at Wauseon, August 6th (Hine) ; one male was 

 taken at Minerva Park, October 10th.
