 not common. 



9. Gom^lius vulgatissimus. — At two streams in the south of the 



Forest. 



10. Gorduleg aster annulatns. — A fine insect, common in the Forest, 

 flying throughout the summer. 



11. Anaximperator. — ^This, the largest European dragonfly, seems to 



be fairly common. Though appearing in- the spring, it extends 

 into August.

13. ^"Eschna mixta. — Occasionally taken — the smallest and least 

 common of the ^schnas of southern Britain. 



14. ^. juncea. — As the previous species, met with occasionally ; not 



easily distinguished on the wing from the following one. 



15. ^. cyanea. — Fairly common in summer and autumn. 



16. u^. grandis. — Not common in the New Forest. Mr. Clark (Ent.

 1901, I saw one at Oberwater. 



17. Calopteryx virgo. — Very common. 



18. G. splendens. — Occurring locally, but not common. 



19. Lestes sponsa.— At ponds, but perhaps not frequent.

time. The form of the female (var. melanotitm), with black- 

 bronze abdomen, occurs. 



22. P. tenellum. — Very common, especially over the bogs. The 



forms of the female (vars. melanogastrum and erythrogastum), 

 with black-bronze and crimson abdomens, respectively, are fairly 

 frequent. 



23. Ischnuva pumilio. — Common in a few localities in the south of 



the Forest, probably breeding in boggy ground. It was re- 

 discovered there, June 3rd, 1900, by Mr. F. M. B. Carr and 

 myself. The var. aurantiacum is frequent. 



24. I. elegans.—'FaXYly common and well distributed. 



25. Agrion puella. — Fairly common. 



26. A. mercuriale. — In several localities — common in some — appear- 

 ing in the spring and remaining on the wing during the summer. 

 It seems to like a stream running through a bog.
