 dlemarsh (J. C. in pencil), and May 11, 1819 (J. C. filled in); (9) Scotch, 1847 ; (10)

 sea (J. C. in pencil), and June 26, 1818 (J. C. filled in). 



Libellula fulva. — Six specimens, of which a male (13) and a female (15) are 

 unlabelled. A male (14) is from Hurne (J. C. in pencil), July 5, 1837 (J. C filled

 1842 (J. C. filled in), and Whittlesea Mere (at side). The three females each bear

Libellula aerulescens.— Seven examples, one female (28) bearing no label. Of 

 the rest five males are thus described : (25) Cosmore Common, July, 1839 (J. C.) ; 

 (26) July 1, 1839 (J. C. filled in), and Middlemarsh (at side) ; (27) Scotch, 1847

 seventh, a female (30) is from Boscombe Chine, June, 1846 (J. C). 



Libellula fl.aveola. — This is one of the more interesting species, owing to the 

 doubt as to whether it breeds in this country, the uncertainty of its appearance and 

 perhaps also the paucity of females pointing to its being a migrant. The cabinet 

 contains seven examples, six males and one female, one of the males (35) being 

 unlabelled. So few British females are known, that this well authenticated example 

 (34) is of considerable importance. Two males (32, 33) and the female (34) appa- 

 rently belong to the same catch, they bear labels (32) Whittlesea, July 16, 37 

 (in MS.) ; (33) iasa/w (J. C), and July 16, 1837 (printed label filled in); (34) 

 Whittlesea (J. C. in red ink), July 16, 37 (J. C), and in pl.f July 16, 37, Stilton 

 Fen (J. C). No. 36 is labelled Ent. Club, (37) has two labels, basalis (Stephens' 

 writing probably), and Mr. Stephens. (38) has Whittlesea Mere (at side).
