Hagen.] 36 [May5, 



The single male I received twenty years ago from Mr. Guex, to- 

 gether with a considerable number of Odonata, all taken in the same 

 place near New York, and all except 2E. grandis common North Amer- 

 ican species, induced me to believe that probably this male of JE. 

 grandis was introduced by a European ship. This is the more proba- 

 ble, as very near Bergen Hill are the immense wharves for the trans- 

 atlantic steamers. At least, thus far no other specimen is known to 

 be found in America. In a letter to Mr. Haldeman, still in my hands, 

 Mr. Guex states, that he is perfectly sure he has not made a mistake 

 in the locality.

New specimens from Florida have convinced me that JE. Abboti, 

 described from the figure by Abbot, is identical with JE. ingens ; the 

 appendages of the figured specimen were probably broken.
