Hagen.J 356 [March 25, 



9. iEschna Janata ? No. 26. Brit. Mus., male, March 26, rare. 

 I gave this determination as doubtful, Stett. Zeit, xxiv, 373, as 



there exists no specimen of this very rare species in European collec- 

 tions. Even now I have only seen two pairs, both from Massachu- 

 setts. My determination was made from Say's description, and a 

 new comparison is necessary. 



Family CORDULEGASTEBINA. 



10. Cordulegaster Sayi. Male, No. 9. Brit. Mus., March 

 30, near Ogechee Biver, not common. 



I have not yet seen specimens from Georgia, besides the typical 

 pair from Abbot in the British Museum. I have also seen one pair 

 from Maryland; also males from Connecticut, Massachusetts, New 

 Hampshire, White Mts., where this species is more common, and Port 

 Neuf in Canada. The northern specimens are smaller and darker. 



11. Cordulegaster maculatus. Female, No. 8. Brit. Mus., 

 March 20, rare. 



1 have seen a female type from Abbot in the Brit. Museum, one 

 female from Maryland and one from the United States in my collec- 

 tion, a male, probably from New England, in Harris' collection, and 

 a male from Woburn, Mass. The species seems to be rare. 



12. Cordulegaster obliquus. 



I possess a male from Abbot, and I saw two smaller ones from Con- 

 necticut and Orono, Me., in Dr. Packard's collection. The female 

 has been taken in Rock Island, 111., according to manuscript state- 

 ments by the late B. D. Walsh. The full comparative descriptions 

 of these species are retained for another paper. 



Family GOMPHINA. 



13. Progomphus borealis. DeSelys, Trois. Addit. au Syn- 

 opsis de Gomphines, 1873, 36. Male, female, No. 52, LeConte. 



The discovery of this genus, hitherto not represented in the fauna 

 of North America, is very interesting. The only male described by 

 De Selys is from Oregon, and I have not seen it, but the descrip- 

 tion agrees; nevertheless, as the specific differences of the Progom- 

 phus species are rather obscure, and as the two localities, Oregon 

 and Georgia, are very distant, perhaps the species from the latter 

 State may prove distinct. All I can say now, is that I am unable to
