Sub-Family Libellvilinae. 



Paiitala Hagen. 



Pantala flavesceiis Fabricius. 

 Calvert, p. 254. 



As stated in Volume I. of the Proceedings of tlie Institute 

 (p. 35, 1899), a male of this species was taken on an island in 

 the Merrimack River at Amoskeag, September 6, 1898. A fe- 

 male was flying with the male when first observed, but escaped 

 capture. September 17, 1900, a female, teneral, imagination 

 evidently having but recently occurred, was taken on the same 

 island. No other individuals have yet been recognized in this 

 vicinity, and it is probable that Manchester is near the extreme 

 northern limit for this species in eastern North America. 

 Platlieiiiis Hagen. 



Platlieiiiis trimaculata De Geer. 

 Calvert, p. 259. 



Several females of this species have been added to the collec- 

 tion. They were quite abundant from the first to the middle 

 of June, being fully two weeks earlier than lyibellula pulchella, 

 to the females of which species they bear so strong an apparent 

 resemblance. 



Naiinothemis Brauer. 



Nannotheinis bella Uhler. 

 Calvert, p. 260. 



This dainty little Dragonfly was found in considerable num- 

 bers at the chain of pools on Goff's Falls Road, from about the 

 middle of June to the first of August. As stated above, it has 

 been found at no other station near Manchester. 



The list of Anisoptera in the collection of the Institute is as 

 yet by no means complete for this vicinity, but in so far as the 

 species have been definitely determined, it is repeated here for 

 the convenience of members. 



Diplax Charpentier has given place to Sympetrum Newman, 

 the latter having priority and being now generally used by writ- 

 ers upon the Odonata.
