De Selys Longchamps on the British Libellulidae. 223 



19. Gomphus flavipes, Charp. ; Steph. 111. pi. 30. f. 1 ; Curt. ; 



Evans, pi. 14. f. 2 (<?). 

 G. pulchellus, Steph. Catal. (nee Selys). 

 England. A single male taken at Hastings on the 5th of August 

 1818 (Mus. Stephens). N.B. I erroneously considered the pul- 

 chellus of Mr. Stephens as identical with another species of Europe 

 which I have described under the same name. This last alone must 

 retain the name of G. pulchellus, Selys. 



20. G.forcipatus, L. 



(Not described by English authors.) 

 G. unguiculatus, Van der Lind., De Selys (olim). 

 JEschna hamata, Charp. 

 England. A single female in the collection of Mr. Stephens, who 

 remembers to have taken it in England. [N.B. The extremity of 

 the abdomen is figured by Mr. Evans by the side of the flavipes as 

 the female.] 



Genus 4. Cor duleg aster. Leach. 



21. Cor duleg aster annulatus, Latr., Steph., Curt. ; Evans, pi. 13. 



f.2. 

 JE. Boltoni, Donov. 

 England. Local : rare. New Forest, York, &c. — Mus. Steph., 

 Dale, &c. 



Scotland. Local. Loch Lomond, Loch Katrine. — Mus. Dr. Gre- 

 ville, Blyth, &c. 



Ireland. Northern Lakes, Haliday. 



Genus 5. Mschna, Fab. 



22. JEiSchna pratensis, Mull. 



M. vernalis, Van der Lind., Steph. ; Evans, pi. 13. f. 1 ; De 

 Selys (olim). 



JE. teretiuscula, Leach, Curt. 



L. aspis, Harris. 

 England. Generally. — Mus. Steph., Curt., Dale, &c. 

 Scotland. Mus. Dr. Greville. 

 Ireland. Mus. Miss Ball. 



23. JR. mixta, Latr. 



JE. affinis, Steph. ; Evans, pi. 12. f. 2 (exclus. syn.). 



N.B. The description given by Mr. Stephens in 1835 relates 

 in part to the true affinis, Van der Lind. 

 jE. anglicana, Leach MSS. 

 L. coluberculus} Harris. 

 England. Local. — Mus. Steph., Curt., Dale, Evans. 

 Scotland. In the south. 



N.B. Perhaps the JE. affinis, Van der Lind., occurs in En- 

 gland : all that I can say is that I have not seen it, and that the 

 types of the species in Mr. Stephens's collection belong to the 

 mixta.
