62 PLATE CCCCXV. 



Libellula iEnea has been recently obferved in fwampy grounds in 

 the neighbourhood of Hampftead. It is recorded as a Britifh Infect 

 by Ray ; but iince his time appears to have become very fcarce 

 till lately, when a fmall number of them were obferved in the above- 

 mentioned fituation. We poffefs two varieties taken in this place, 

 in the fummer of 1 805, which differ in fome flight particulars only. 

 Both infe&s have the eyes of a brown colour, and the thorax of 

 a brilliant green with a braffy luftre: the principal difference 

 confifts in the colour of the wings, which in one fpecimen are hyaline, 

 while on the contraiy the wings of the other are tinged with 

 teftaceous yellow. This yellow-winged variety is further diftinguifhed 

 by having the body gloffed with fine golden purple ; in the other, the 

 body is of a braffy green colour, with only a flight inclination to 

 reddifh brown *. Both infects are figured in the annexed plate in 

 their natural fize. 



This fpecies is not peculiar to England. Linnaeus defcribes it as a 

 native of Sweden ; from Geoffroy we learn, that it is a native of 

 France ; and from Roefel, as being found in Germany. 



* An indifferent figure of a fpecies of Libellula, much refembling this, occurs in the 

 ■work of Schaeffer, Icon. Ratif. pi. 167, fig. 4, and which is probably intended for our 

 yellow-winged variety.
