proven incorrect and the following statements may be made in 

 order to harmonize his publications with recent conclusions of the 

 foremost students of Odonata. 



In Volume XII of Entomological News, page 65, Dr. Calvert 

 gives a comparative study of three closely related species of this 

 genus. After studying Ohio material as well as much material 

 from other sections he announces that Gomphus fraternus var. 

 walshii as published in Jour. Cin. Soc. Nat. Hist. XVIII, p. 107, 

 and Gomphus externus in Odonata of Ohio, page 60, should be 

 changed to Gomphus crassus Hagen. 



Gomphus intricatus mentioned in Agricultural Student, Vol. 

 Ill, page 143, and Gomphus sp. Jour. Cin. Soc. of Nat. Hist., 

 Vol. XIX, page 67, are referable to Gomphus notatus Rambur. 



Gomphus notatus Ramb. as used by Dr. Kellicott in Jour. Cin. 

 Soc. Nat. Hist., Vol. XIX, page 67, is Gomphus plagiatus Selys, 

 as we know it at the present time. 



Celithemis fasciata Kirby, Odonata of Ohio, page 104, and in 

 Dr. Kellicott's other writings, is referable to Celithemis monome- 

 Isena Williamson, which was described as a new species in Ohio 

 Naturalist, Volume X, page 153, and the reader is referred to 

 this paper for particulars. 



The following changes and statements are supplementary to 

 the Odonata of Ohio and are made for the benefit of future students 

 and collectors of the order in the state: 



Enallagma antennata (Say) to be used instead of Enallagma 

 fischeri Kellicott. 



Gomphus crassus Hagen to be used instead of Gomphus 

 externus Selys. 



Celithemis monomelasna Williamson to be used instead of 

 Celithemis fasciata Kirby. 



Gomphus lividus Selys should stand as it is, since Gomphus^ 

 sordidus Hagen is now considered a synonym. 



Gomphus plagiatus Selys, spoken of with some doubt, is 

 correct as given. 



Gomphus notatus Rambur is correct as given and additional 

 Ohio species have been procured. 



The following species have been taken in the state and should 

 be added to the Ohio list: 



Calopteryx angustipenne (Selys), was procured near Loudon- 

 ville by Osbuni and Parker, June 10, 1S99. Additional specimens 

 were procured at the same place in June, 1900. 



Lestes eurinus Say, taken in Portage County, June 3, 1900, by 

 E. B. Williamson. Nvimerous specimens of both sexes taken on 

 Cedar Point, Sandusky, by the writer, July 10, 1900. 



Gomphoides obscura (Rambur), taken by R. C. Osburn, at 

 Ironton, June 1, 1899. Additional specimens taken bv mvself at 

 Vinton, June 10, 1900.
