Libellula cyanea Fabr., Ent. Syst., 381, 36. 



Hab. Milton, Cambridge, Beverly, Natick, Woburn, Massachu- 

 setts, June, July ; New Jersey; Maryland. 



I have no doubt that L. cyanea F., is this species; the only objec-

 possess males agreeing with this character.

Libellula plumbea Uhler! Proc. Acad. Philad., 1857, 87, 2.— Hag. J 

 Syn., 157, 17; Stett. Z., xxiv, 375, 74; xxvin, 91; Proc. Bost. 

 Soc. Nat. Hist, xvi, 362, 39. 



Hab. New Jersey ; Baltimore, Maryland, July ; Georgia, April 

 27, common. 



Perhaps this species is Cordulia costalis Selys from Georgia. I 

 should be nearly sure of it, had not Baron De Selys stated that he 

 had again examined the female type in the British Museum.

 doubtful) ; Matamoras, Mexico (one male) ; Cuba, migrates in June 

 and November ; Hayti, April, May in Jeremie ; St. Thomas ; Barba- 

 dos ; common in S. America. 



The female with the band of the wings as in the male is very rare ; 

 I have seen three specimens from Cuba. 



The race L. tripartita belongs to the West India Islands. There
