56. LlBELLULA PULCHELLA Drury. 



Abundant in all parts. At Columbus from June to Sep- 

 tember 15. 



There are a few regional species not yet in hand, e. g. } In- 

 tacta, occurs in Central Michigan ; Exnsta, it is supposed, was 

 seen by W. E. Kellicott in Franklin Park ; it could not be 

 taken, as the police appeared at the same time. 



57. Plathemis trimacllata De Geer. 



Common in all parts explored. Columbus from May 6 to 

 September. 



Celithemis. 

 58. Celithemis eponina Drury. 



r 



Very abundant at Licking Reservoir, July 20; Ottawa 

 River, August 1. Taken also at Sandusky, Lancaster, and 

 Oberlin (Lynds Jones). 



59. Leucorhinia intacta Hagen. 



Very generally distributed, and usually abundant. In 

 Woodlawn Cemetery, Chicago, June 25, 1893, I found this 

 form literally in swarms about the " lakes." It was not in 

 accordance with the wishes of those in charge that an insect 

 net should be used to take them, so I resorted to " hand- 

 picking," and readily secured a dozen pairs, as they rested on 

 the shrubbery. 



60. Diplax rubicuxdula Say. 



Everywhere abundant. 



At Columbus from June 8 to October 7. 



61. Diplax assimilata Uhler. 



Not uncommon at Columbus in August and September. 

 Toledo, August 1.
