87. Enallagma doubledayi Selys. 



Two males were captured by Mr. Hine at Minerva Park, 

 May 4th. It has not been seen elsewhere in the State. The 

 discovery of doubledayi in Central Ohio was quite unexpected, 

 as it has not been reported previously from the interior. W. 

 F. Kirby, in his Catalogue of the Odonata of the World, 

 gives its habitat Florida and Cuba. Philip P. Calvert has 

 reported it from one of the Elizabeth Islands.

88. Ophiogomphus rupinsulensis Walsh. 



The first capture, a teneral male, was made by Mr. C. B. 

 Steward on the State University Campus, 1 May 5th. From 

 the middle of May until the middle of June it was common, 

 in company with G. fraternus and G. exteruus, flying above 

 the swiftest water of the Olentangy River at Columbus or rest- 

 ing on its gravelly banks, near rapids. 



89. Gomphus quadricolor Walsh. 



One female was taken May 20th by Mr. Ernest Scott on the 

 grounds of the State University. Two males were subse- 

 quently captured by the writer at Columbus. One was resting 

 on a rock jutting out of swift water and one on the bank 

 near by. It is an elegant and, apparently, not very active 

 species. 



90. Gomphus notatus Rambr. 



Teneral males and females were taken at Sandusky, June 

 20th. It occurred about the sand dunes on Cedar Point (San- 

 dusky), resting on coarse grasses, through July. None were 

 seen ovipositing or flying, except to escape from danger. 

 Nymphs crawled up piles and walls in the harbor for their 

 final change, which shows that they inhabited water of consid- 

 erable depth. 



91. Gomphus Sp. 



One female taken by Jas. S. Hine at Wauseon, July 1st. 

 It appears to belong to the same group as G. notatus, but dif-
